MEDICINA (KAUNAS, LITHUANIA) 2024; 60:928. [PMID: 38929545 PMCID: PMC11206099 DOI: 10.3390/medicina60060928] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 05/22/2024] [Accepted: 05/30/2024] [Indexed: 06/28/2024]
Abstract
Background and Objectives: This study aimed to determine the relationship between non-simultaneous contralateral hip fractures, urban and rural differences, fracture localization, time between fractures, physiotherapy applications, comorbidity, and the second fracture outcomes. Materials and Methods: We retrospectively analyzed 107 patients aged 65 and older with proximal femur fractures (PFFs) who underwent surgery at Düzce University Medical Faculty between January 2010 and December 2022. High-energy fractures, pathological fractures, and patients with a history of old fractures were excluded. Results: The study included 66 females (61.7%) and 41 males (38.3%), with a mean age of 83.76 years. The mean interval between two fractures was 28.3 months. There was no statistical difference between the localization of the first and second fractures (p = 0.107). However, there was a significant difference in the first PFF localizations of patients living in rural areas (p = 0.023). Patients with heart failure, respiratory failure, osteoporosis, and cognitive impairment had shorter intervals between fractures (p < 0.001). Conclusions: This study shows that age, female gender, place of residence, comorbid diseases, and whether physical therapy is received after the first fracture are significant risk factors for a second hip fracture in patients over 65 years of age.

Abstract
Maintaining post-operative mechanical stability is crucial for successfully healing intertrochanteric fractures treated with the Proximal Femoral Nail Antirotation (PFNA) system. This stability is primarily dependent on the bone mineral density (BMD) and strain on the fracture. Current PFNA failure analyses often overlook the uncertainties related to BMD and body weight (BW). Therefore, this study aimed to develop a probabilistic model using finite element modeling and engineering reliability analysis to assess the post-operative performance of PFNA under various physiological loading conditions. The model predictions were validated through a series of experimental test. The results revealed a negative nonlinear relationship between the BMD and compressive strain. Conversely, the BW was positively and linearly correlated with the compressive strain. Importantly, the compressive strain was more sensitive to BW than to BMD when the BMD exceeded 0.6 g/cm3. Potential trabecular bone compression failure is also indicated if BMD is equal to or below 0.15 g/cm3 and BW increases to approximately 2.5 times the normal or higher. This study emphasizes that variations in the BMD significantly affect the probability of failure of a PFNA system. Thus, careful planning of post-operative physical therapy is essential. For patients aged > 50 years restrictions on high-intensity activities are advised, while limiting strenuous movements is recommended for those aged > 65 years.

[PMID: 38159332 DOI: 10.1016/j.injury.2023.111279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 11/28/2023] [Accepted: 12/10/2023] [Indexed: 01/03/2024]
Abstract
INTRODUCTION Hip fractures among the elderly exhibit diverse patterns. Differences regarding treatment and prognosis of displaced versus undisplaced intracapsular fractures are well established. Unstable extracapsular fractures are associated with considerably higher rates of complications than stable fractures, including cutout failures, non-unions, wound complications and hardware related problems. The purpose of this study was to identify trends in the distribution of various types of hip fractures and their complexity between 2001 and 2022. METHODS This retrospective study compared hip fractures treated in the years 2001, 2006, 2010, 2014, 2018, and 2022, excluding patients under 60 years old and those with pathological or peri‑prosthetic fractures. Radiographs were reviewed and fracture patterns were categorized as stable extracapsular, unstable extracapsular, subtrochanteric or intracapsular. RESULTS Out of 2646 patients admitted with proximal femoral fractures during these years, 2277 patients (69.5 % women) were available for analysis. Over the initial decade, the mean patient age gradually increased from 80 to 82, subsequently stabilizing. Gender distribution remained consistent, and the proportion of intracapsular fractures showed minimal variation (36-38 %). The most significant finding was the marked decrease in the proportion of stable-to-unstable extracapsular fractures during the first decade from 51 % to 31 %, followed by stabilization after 2010. Subgroup analysis by age revealed that while the proportion change between stable and unstable fractures remained insignificant in younger age groups (p = 0.41 for sexagenarians and 0.12 for septuagenarians), a significant change was observed in older patients (p = 0.002 for octogenarians and 0.04 for nonagenarians and older patients). DISCUSSION This study reveals a surge in unstable peritrochanteric fractures between 2001 and 2010, particularly pronounced in patients over 80. This trend plateaued in the following decade, aligning with the stabilization of the cohort's mean age at 82. Numerous factors, from bone morphology to systemic markers, influence hip fracture types. Evolutions in osteoporosis screening and treatment over the last three decades may have contributed to the observed shifts in fracture pattern distribution. CONCLUSION Understanding these trends enriches treatment strategies and underscores the need for further exploration of the interplay between demographic and anatomical factors in the etiology of specific fracture patterns.

Intertrochanteric Femoral Fractures: A Comparative Analysis of Clinical and Radiographic Outcomes Between Talon Intramedullary Nail and Intertan Nail. Cureus 2023; 15:e50877.

Abstract
Introduction Hip fractures in the elderly constitute a significant health concern, and their incidence is on the rise. It has been reported that intertrochanteric femoral fractures comprise a large portion of hip fractures, and they are especially prevalent among women. Over 75% of these types of fractures in the elderly occur as a result of simple falls. Surgical intervention must be performed for these fractures to expedite the healing process in patients. The application of a proximal femoral nail (PFN) is conducted using a minimally invasive technique after the fracture has been reduced using closed techniques. This technique maintains the fracture hematoma while minimizing the occurrence of consequences such as surgical trauma, hemorrhaging, infection, and issues with the wound site. This study aimed to assess the radiologic and functional outcomes among the groups following surgical procedures utilizing two distinct PFNs. Methods Between November 2021 and June 2023, a total of 96 individuals (38 males and 58 females) who underwent surgery for ITF using PFN were included in the study. Our surgical team utilized the Talon™ DistalFix™ PFN system (Orthopedic Designs North America Inc., FL, USA) and the Trigen InterTAN® nail (Smith & Nephew). Results The surgery time (number of scopes) for the Talon PFN was recorded as 25 (25-30), while it was 30 (30-35) in the InterTAN group (p<0.001). No nail protrusion was observed in the InterTAN group, whereas nail protrusion was observed in 12 patients (31.6%) in the Talon PFN group (p<0.001). Nail jamming was observed in two (5.3%) patients in the Talon PFN group, while none was observed in the InterTAN group (p<0.07). Conclusion In ITF fractures, the InterTAN nail is a more reliable implant. The shorter surgery time, reduced radiation exposure, and more minimally invasive nature of the Talon PFN might be preferred for geriatric patient populations with comorbidities where prolonged anesthesia could elevate mortality risks or for fractures of two or three pieces (Evans-Jansen Type 1 and Type 2). However, for more unstable fractures (Evans-Jensen Type 3) and in the active elderly patient group, we recommend the use of the InterTAN nail.

Abstract
PURPOSE This study was designed to compare clinical outcomes of the femoral stable interlocking intramedullary nail (FSIIN) with proximal femoral nail anti-rotation (PFNA) for the treatment of intertrochanteric fractures (OTA 31A1 + A2). METHODS This study retrospectively analyzed a registered sample of 74 intertrochanteric fractures (OTA 31A1 + A2) surgically treated using FSIIN (n = 36) or PFNA (n = 38) from January 2015 to December 2021. The intra-operative variables (operation time, fluoroscopy time, intra-operative blood loss, length of incision) and fracture healing time were compared between the two groups in this study. Harris hip score (HHS) and visual analog scale (VAS) were used to evaluate the functional states. At the last follow-up, the incidence of related complications in patients was calculated. Eventually, the 3D finite element model was established to analyze the stress of FSIIN and PFNA. RESULTS The distribution of all basic characteristics was similar between the two groups (p > 0.05). The operation time, fluoroscopy time, intra-operative blood loss, and length of incision were significantly decreased in the FSIIN group (p < 0.001). The FSIIN group had a shorter fracture healing time than the PFNA group (p < 0.001). There is no significant difference between the two groups in the Harris and VAS (p > 0.05). The incidences of post-operative anaemia, electrolyte imbalance, varus malalignment, and thigh pain were significantly lower in FSIIN than in PFNA groups (all p < 0.05). The finite element results show that the stress shielding effect of FSIIN is smaller. CONCLUSIONS Our study revealed that FSIIN seemed to be superior to PFNA in the treatment of intertrochanteric fractures (OTA 31A1 + A2) due to less surgical damage and shorter fracture healing time.

Abstract
BACKGROUND Hip fractures are still unsolved problems nowadays. We evaluated the functional outcomes and complications in the treatment of hip fractures (AO/OTA31A1-A3) to find potential difference and risk between intramedullary nail (IMN) and dynamic hip screw (DHS). METHOD We searched PubMed, Embase, Cochrane library up to 19 June 2023 and retrieved any studies comparing IMN and DHS in treatment of Hip fractures. The main outcomes and complications were extracted from the included studies. The fixed-effect model was selected to pool the data for homogeneous studies (I2 < 50%). Otherwise, the random effects model was selected (heterogeneity, I2 > 50%). The analysis of sensitivity and subgroup was performed to explore the homogeneous studies among studies. The p-value of less than 0.05 was considered statistically significant. RESULTS 30 RCT studies were included in this meta-analysis. There were significant difference of in the items of blood loss, screening time, femoral neck shortening, non-union, and femoral fractures (p < 0.05). Significant difference was found in the parameter of open reduction of fracture after sensitive analysis (p < 0.05). No significant difference was found in the parameter of Mobility Score at the last follow-up after sensitive analysis (p ≥ 0.05). There was no significant difference in the parameters of open reduction of fracture, required blood transfusion, mean surgical time, hospital stays, time to healing, mean Harris Hip Score, infection, cut out, poor reduction, breakage of implant, failure of fixation, reoperation, and systemic complications of chest infection, decubital ulcer, urinary tract infection and persistent pain in the hip (p ≥ 0.05). CONCLUSIONS Our meta-analysis revealed that hip fractures treated with IMN have merits with lower rate of blood loss, femoral neck shortening and non-union; shortcoming of increased risk of femoral fractures. It is suggested that special attention should be paid to the risk of femoral fracture when intramedullary nail was inserted in the intraoperative.

Abstract
AIMS To compare in a prospective randomized trial the mechanical complications in patients with unstable extracapsular proximal femur fractures without subtrochanteric extension (AO/OTA 31-A2 and 31-A3) METHODS: We prospectively studied 182 patients with unstable extracapsular proximal femur fractures without fractures lines extending more than 3 cm below the lesser trochanter, randomized to receive either a 'standard' (240 mm) nail or a long nail and followed them up for 1 year. RESULTS We found no difference in the incidence of mechanical or general complications between the two groups, no cut-outs, no fractures of the tip the implant, 1 cut-through and 2 malrotations in the LN group, 2 non-unions that were reoperated, one on each group. The commonest complication was blade lateral migration, 13 (14%) patients in SN and 6 (9%) in the LN. The operating time was shorter in the SN group 51 minutes compared to 67 minutes in the LN group (p=0.000075). The mortality at 1,3 and 12 months in the SN group was of 2%, 6%, 12% while in the LN group was 12%, 18% and 22%. These differences where significative at 1 (p=0.007) and 3 months (p=0.013), but not at 12 months (p=0.075). CONCLUSIONS We recommend the use of standard nails (240 mm) for this group of fractures, since it does not produce more mechanical complications, and it is faster, cheaper and easier to interlock distally.

Abstract
Background The primary objective of the present study was to compare surgical failures of intertrochanteric fractures of the femur through a meta-analysis of randomized controlled trials and to assess the change in surgical outcomes over time in a cumulative meta-analysis. Methods To identify studies evaluating the surgical outcomes of internal fixation using sliding hip screws (SHS) or cephalomedullary (CM) nails for the treatment of intertrochanteric fractures of the femur, all records until August 2021 in the PubMed, Embase, and Cochrane Library databases were searched. Studies with the following characteristics were considered eligible: patients who had an intertrochanteric fracture of the femur (population); patients who received surgical treatment using a CM nail (intervention); patients who received surgical treatment using SHS (comparator); surgical failures that required reoperation, including cut-out or cut-through of lag screws, varus collapse or posterior angulation of proximal fragments, loosening of lag screws or helical blades, and fracture nonunion (outcomes); and two reviewers independently reviewed the titles and abstracts of the randomized controlled trials and selected relevant studies for a full-text review (study design). Results Twenty-one studies were included in the final analysis consisting of 1,777 cases in the SHS group and 1,804 cases in the CM nail group. The cumulative standard mean difference was 0.87, indicating that CM nails had no significant effect in improving the surgical outcomes. There was no significant difference in surgical failure between SHS and CM nails for all intertrochanteric fractures (odds ratio [OR], 1.07; 95% confidence interval [CI], 0.76-1.49). Pooled data showed no significant difference between the two groups in terms of surgical failure in unstable intertrochanteric fractures (OR, 0.80; 95% CI, 0.42-1.54). Conclusions Although the use of CM nails has become a current trend in the treatment of intertrochanteric fractures, there is no literature supporting their clinical superiority when compared with SHS.

Abstract
Background Neck of femur (NOF) fractures, including intertrochanteric fractures, are common fragility fractures seen in the elderly population and are often amenable to fixation with a proximal femoral nail (PFN). However, there is conflicting evidence regarding the incidence of peri-prosthetic fractures with each device. Several studies from the 1990s and a recent meta-analysis have shown a higher incidence of peri-prosthetic fractures in the short PFN cohort. Other studies have shown a lower reoperation rate with short PFNs, and no statistically significant differences have been quoted in the rates of peri-prosthetic fractures in systematic reviews. Aim The purpose of this retrospective study, therefore, was to assess the peri-prosthetic fracture rate and failure rates of elderly neck of femur (NOF) fractures implanted with either a short or long proximal femoral nail (PFN). Materials and methods A retrospective study was conducted in a single orthopaedic department (University Hospital Dorset, Poole, GBR) using collected data on all extracapsular neck of femur fracture patients from the national hip fracture database (NHFD) from January 1, 2011, to December 23, 2021. The data collected included patient age, sex, the American Society of Anesthesiologists (ASA) type of neck of femur fracture, type of surgery performed, any further peri-prosthetic fractures, and time to re-operation in that subset of the group. The implants used were the Stryker Gamma 3 Nail and the Smith Nephew (Trigen and Intertan). All patients were allowed to fully weight bear as tolerated and received both orthopaedic and elderly medical care. Failure was defined as a cut-out or implant fracture. Results From January 1, 2011, to December 23, 2021, there were 1010 extracapsular neck of femur fractures recorded on the National Hip Fracture Database (NHFD) treated with a PFN from the study centre. Of those patients, 11 had pathological fractures and were excluded. 649 patients had long PFNs, and 350 had short PFNs. Of the total of 999 patients, 254 (25%) were male and 745 (75%) were female. More than 80% of the patients in the sample were over the age of 75. The majority of patients in both groups had A1/A2 fractures (short 84.3%, long 49.1%). The rate of periprosthetic fractures in the short PFNs was 1.71%, and the failure rate was 0.57%. The rate of periprosthetic fractures in the long PFNs was 0.62%, with a failure rate of 0.92%. The multi-nominal logistic regression model did not show statistically significant odds ratios (OR) for the following variables: long/short nails, male/female gender, age, ASA, or type of fracture. The female gender was associated with a higher risk of both periprosthetic fractures and failures (OR of 2.232 and 2.95), but this was not found to be statistically significant. Similarly, unstable A3 fractures had a much higher risk of failure (OR of 2.691) compared to periprosthetic fractures (OR of 0.985). However, this was not statistically significant. Conclusion Overall, this study has identified that in a patient population that is predominantly female and over the age of 75, the risk of periprosthetic fracture rate and the failure rate is similar in both the use of a short or a long PFN for intertrochanteric fractures.

Abstract
BACKGROUND Surgery for intertrochanteric fractures using intramedullary hip nails (IHNs) is among the most common surgical procedures in the orthopedic field. Although IHNs provide good overall outcomes, they sometimes cause complications, such as loss of reduction and cut-out. Here, we investigated the usefulness of IHNs with an anterior offset (Best Fit Nail® [BFN]) in maintaining fragment reduction and ensuring proper lag screw position compared with conventional non-offset nails (Proximal Femoral Nail Antirotation® [PFNA]), using postoperative computed tomography (CT). METHODS Fifty consecutive patients with intertrochanteric fractures who underwent surgery with BFNs (BFN group) and 50 patients who underwent surgery with PFNAs (PFNA group) were retrospectively analyzed. Indices evaluated by postoperative CT were displacement distance of proximal fragment relative to distal fragment, reduction status (intramedullary, anatomical, and extramedullary types), lag screw direction, and angle between lag screw and femoral neck axis (deviation angle). RESULTS Median [interquartile range] displacement distance was significantly smaller in the BFN group (0 [0, 0] mm) compared with the PFNA group (5.2 [3.6, 7.1] mm) (p<0.001). Reduction status was significantly better in the BFN group (anatomical type, 40 cases; intramedullary type, in 9 cases, and extramedullary type in 1 case) than in the PFNA group (anatomical type, 6 cases; intramedullary type, 43 cases; extramedullary type, 1 case) (p<0.001). Deviation of lag screw direction was observed in significantly fewer cases in the BFN group (20 cases; 40%) compared with the PFNA group (36 cases; 72%). Lag screw deviation angle was significantly smaller in the BFN group (-0.71°±4.0°) compared with the PFNA group (6.9°±7.1°). No adverse events related to surgery were observed in either group. CONCLUSIONS Intertrochanteric fracture surgery using offset BFNs exhibited significantly smaller displacement distance, better reduction status, and higher frequency of no deviation with central lag screw position, compared with surgery using non-offset PFNAs.

Abstract
BACKGROUND IM nails are the gold standard of subtrochanteric fractures management. Indications to use a short rather than a long nail remain unclear. Operative complications of subtrochanteric fractures reach up to 25%. OBJECTIVE Retrospectively compare clinical and radiographic outcome of subtrochanteric fractures treated by long and short intramedullary nailing, analysing rates of complications. METHODS 390 patients were chosen from the archives. 194 patients were available: 70 treated with a short intramedullary nail (Group A), while 124 with long one (Group B). Radiographic evaluation at 6 and 12 months assess failure of the osteosynthesis. Clinical outcomes were the return to normal activities prior trauma and VAS scale. Group A mean age was 81.37 years, group B mean age was 78.9 years (29-99, SD: 15.38). RESULTS Radiografic Healing was found in 66 patients (94.28%) in group A, while in 116 patients (94.54%) in group B. Pseudarthrosis was found in 4 cases (5.71%) in group A, while in 8 cases (6.45%) in group B. Implant failure occurred in 5 cases: one required revision of fixation, while 4 require hip replacement. 59 patients of group A (84.29%) returned to social life, while 102 patients (81.94%) in group B. Group A mean VAS was 1.55, Group B mean VAS was 1.49. CONCLUSION Comparison of the two group showed no differences. Complication percentages are in line with literature. Optimal reduction and fixation allow high percentage of healing and return to social life.

Periprosthetic fracture rate after short and long hip nails: Analysis of a regional health database. Injury 2022; 53:2195-2198. [PMID: 35341598 DOI: 10.1016/j.injury.2022.03.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Accepted: 03/01/2022] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Intertrochanteric hip fractures are a major socio-economic burden, and a significant source of morbidity and mortality. Treatment is generally surgical, with either a dynamic hip screw or a cephalomedullary hip nail. Recently, there has been a trend toward the use of hip nails. The use of short nails over long nails, which span the length of the femur, remains a source of controversy. Historically, short nails were associated with a higher periprosthetic fracture rate compared with long nails, however newer nail designs, appear to have resolved this issue. Small retrospective studies show a refracture rate similar in both long and short nails. Given the small sample size of current studies, it remains unclear if the refracture rate is indeed the same between treatment arms, or if studies are not sufficiently large to identify a difference between the two. A large database review would provide the practical next step to further explore this question. METHODS Intertrochanteric hip fracture cases from our Regional Hip Fracture Registry were reviewed. All patients with an intertrochanteric fracture treated with a cephalomedullary nail from June 2009 to December 2017 were included. Patient demographics were compared using the t-test. Fracture rate was compared using the chi square test. RESULTS 655 short nails and 315 long nails were reviewed. Patients in the short nail (SN) group were older than in the long nail group (LN) (SN: 81, LN 76 p < 0.001). The periprosthetic fracture rate was 2.1% overall with 1.3% in LN group and 2.4% in SN group (p = 0.34). There was no difference identified in the rate of blood transfusions (SN 38% LN 40% p = 0.5), however the procedure time was shorter in the SN group (SN: 81 min LN: 112 min p < 0.001). DISCUSSION This study did not find a statistical difference in periprosthetic fracture rate when comparing short and long cephalomedullary nails for the treatment of intertrochanteric fractures. Procedure time was shorter in the SN group. However, no difference in rate of blood transfusion was noted between patient groups. This study supports use of both nail type for hip fracture fixation, on the basis of periprosthetic fracture rate.

Abstract
BACKGROUND The literature is inconclusive as to whether an intramedullary nail changes the distribution of a subsequent ipsi- or contralateral fracture of the femur. We have compared the incidence, localisation, and fracture pattern of subsequent femoral fractures after intramedullary nailing of trochanteric or subtrochanteric fractures in patients without previous implants in either femur at the time of surgery. METHODS Retrospective analysis was performed of a two-centre cohort of 2012 patients treated with a short or long intramedullary nail for the management of trochanteric or subtrochanteric fracture between January 2005 and December 2018. Subsequent presentations with ipsi- and contralateral femoral fractures were documented. Only patients with no previous femoral surgery performed, other than the index nailing were followed. Odds ratios (ORs) for subsequent femoral fracture were calculated using robust variance estimates in logistic regression. RESULTS The mean age of the cohort was 82.4 years and 72.1% were female. The total number of patients presenting with subsequent femoral fractures was 299 (14.9%). The number of patients presenting with subsequent ipsilateral and contralateral femoral fractures was 51 (2.5%) and 248 (12.3%) respectively (OR 5.0; CI 3.7-6.9). Twenty-six (8.7%) of all subsequent femoral fractures occured in the ipsilateral shaft, 14 (4.7%) in the ipsilateral metaphyseal area, one (0.33%) in the contralateral shaft, and three (1.0%) in the contralateral metaphysis (OR 10; CI 3.6-29). CONCLUSION An intramedullary nail significantly changes the fracture pattern in the event of a second low-energy trauma, reducing the risk of subsequent proximal ipsilateral femoral fractures and increasing the risk of subsequent ipsilateral femoral fractures in the shaft and distal metaphyseal area compared with the native contralateral femur.

Abstract
PURPOSE Cephalomedullary nails are used widely today for pertrochanteric fractures, and intraoperative lateral wall fractures can cause adverse effects. Recently, a high incidence of coronal fragments in pertrochanteric fractures was reported when analyzed with 3D CT reconstructions. In this study, we analyzed the association between the type of coronal fragments and perioperative lateral wall fractures. METHODS Patients diagnosed with pertrochanteric fractures and treated by cephalomedullary nails at three university hospitals from September 2016 to December 2020 were examined. A total of 463 patients were included. We examined the coronal fragments and divided the patients into two groups according to the involvement of the posteromedial cortex. Postoperative X-rays were scanned for fracture lines at the blade entry site. RESULTS Twenty-two patients among 463 patients had perioperative lateral wall fractures. The AO type A2 fractures, use of provisional pins, existence of coronal fragments, involvement of the posteromedial cortex, and the existence of anterior big neck fragments were significantly relevant to perioperative lateral wall fractures. 11 of 22 lateral wall fracture patients were delayed fracture patients, identified 4 weeks after surgery. A coronal fragment combined by anterior big neck fragments had a 9.24 times higher risk of lateral wall fractures compared to fractures with only coronal fragments. CONCLUSION Pertrochanteric fractures with large coronal fragments and anterior big neck fragments have a high risk of perioperative lateral wall fractures when treated by cephalomedullary nails. Surgeons should examine the width of the intact lateral wall, and take caution to preserve its integrity.

Abstract
BACKGROUND Hip fractures are a major healthcare problem, presenting a challenge and burden to individuals and healthcare systems. The number of hip fractures globally is rising. The majority of extracapsular hip fractures are treated surgically. OBJECTIVES To assess the relative effects (benefits and harms) of all surgical treatments used in the management of extracapsular hip fractures in older adults, using a network meta-analysis of randomised trials, and to generate a hierarchy of interventions according to their outcomes. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Web of Science and five other databases in July 2020. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing different treatments for fragility extracapsular hip fractures in older adults. We included internal and external fixation, arthroplasties and non-operative treatment. We excluded studies of hip fractures with specific pathologies other than osteoporosis or resulting from high-energy trauma. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion. One review author completed data extraction which was checked by a second review author. We collected data for three outcomes at different time points: mortality and health-related quality of life (HRQoL) - both reported within 4 months, at 12 months and after 24 months of surgery, and unplanned return to theatre (at end of study follow-up). We performed a network meta-analysis (NMA) with Stata software, using frequentist methods, and calculated the differences between treatments using risk ratios (RRs) and standardised mean differences (SMDs) and their corresponding 95% confidence intervals (CIs). We also performed direct comparisons using the same codes. MAIN RESULTS We included 184 studies (160 RCTs and 24 quasi-RCTs) with 26,073 participants with 26,086 extracapsular hip fractures in the review. The mean age in most studies ranged from 60 to 93 years, and 69% were women. After discussion with clinical experts, we selected nine nodes that represented the best balance between clinical plausibility and efficiency of the networks: fixed angle plate (dynamic and static), cephalomedullary nail (short and long), condylocephalic nail, external fixation, hemiarthroplasty, total hip arthroplasty (THA) and non-operative treatment. Seventy-three studies (with 11,126 participants) with data for at least two of these treatments contributed to the NMA. We selected the dynamic fixed angle plate as a reference treatment against which other treatments were compared. This was a common treatment in the networks, providing a clinically appropriate comparison. We downgraded the certainty of the evidence for serious and very serious risks of bias, and because some of the estimates included the possibility of transitivity owing to the proportion of stable and unstable fractures between treatment comparisons. We also downgraded if we noted evidence of inconsistency in direct or indirect estimates from which the network estimate was derived. Most estimates included the possibility of benefits and harms, and we downgraded the evidence for these treatments for imprecision. Overall, 20.2% of participants who received the reference treatment had died by 12 months after surgery. We noted no evidence of any differences in mortality at this time point between the treatments compared. Effect estimates of all treatments included plausible benefits as well as harms. Short cephalomedullary nails had the narrowest confidence interval (CI), with 7 fewer deaths (26 fewer to 15 more) per 1000 participants, compared to the reference treatment (risk ratio (RR) 0.97, 95% CI 0.87 to 1.07). THA had the widest CI, with 62 fewer deaths (177 fewer to 610 more) per 1000 participants, compared to the reference treatment (RR 0.69, 95% CI 0.12 to 4.03). The certainty of the evidence for all treatments was low to very low. Although we ranked the treatments, this ranking should be interpreted cautiously because of the imprecision in all the network estimates for these treatments. Overall, 4.3% of participants who received the reference treatment had unplanned return to theatre. Compared to this treatment, we found very low-certainty evidence that 58 more participants (14 to 137 more) per 1000 participants returned to theatre if they were treated with a static fixed angle plate (RR 2.48, 95% CI 1.36 to 4.50), and 91 more participants (37 to 182 more) per 1000 participants returned to theatre if treated with a condylocephalic nail (RR 3.33, 95% CI 1.95 to 5.68). We also found that these treatments were ranked as having the highest probability of unplanned return to theatre. In the remaining treatments, we noted no evidence of any differences in unplanned return to theatre, with effect estimates including benefits as well as harms. The certainty of the evidence for these other treatments ranged from low to very low. We did not use GRADE to assess the certainty of the evidence for early mortality, but our findings were similar to those for 12-month mortality, with no evidence of any differences in treatments when compared to dynamic fixed angle plate. Very few studies reported HRQoL and we were unable to build networks from these studies and perform network meta-analysis. AUTHORS' CONCLUSIONS: Across the networks, we found that there was considerable variability in the ranking of each treatment such that there was no one outstanding, or subset of outstanding, superior treatments. However, static implants such as condylocephalic nails and static fixed angle plates did yield a higher risk of unplanned return to theatre. We had insufficient evidence to determine the effects of any treatments on HRQoL, and this review includes data for only two outcomes. More detailed pairwise comparisons of some of the included treatments are reported in other Cochrane Reviews in this series. Short cephalomedullary nails versus dynamic fixed angle plates contributed the most evidence to each network, and our findings indicate that there may be no difference between these treatments. These data included people with both stable and unstable extracapsular fractures. At this time, there are too few studies to draw any conclusions regarding the benefits or harms of arthroplasty or external fixation for extracapsular fracture in older adults. Future research could focus on the benefits and harms of arthroplasty interventions compared with internal fixation using a dynamic implant.

Abstract
BACKGROUND Hip fractures are a major healthcare problem, presenting a substantial challenge and burden to patients, healthcare systems and society. The increased proportion of older adults in the world population means that the absolute number of hip fractures is rising rapidly across the globe. Most hip fractures are treated surgically. This Cochrane Review evaluates evidence for implants used to treat extracapsular hip fractures. OBJECTIVES To assess the relative effects of cephalomedullary nails versus extramedullary fixation implants for treating extracapsular hip fractures in older adults. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Web of Science, the Cochrane Database of Systematic Reviews, Epistemonikos, ProQuest Dissertations & Theses, and the National Technical Information Service in July 2020. We also searched clinical trials databases, conference proceedings, reference lists of retrieved articles, and conducted backward-citation searches. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing cephalomedullary nails with extramedullary implants for treating fragility extracapsular hip fractures in older adults. We excluded studies in which all or most fractures were caused by a high-energy trauma or specific pathologies other than osteoporosis. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We collected data for seven critical outcomes: performance of activities of daily living (ADL), delirium, functional status, health-related quality of life, mobility, mortality (reported within four months of surgery as 'early mortality'; and reported from four months onwards, with priority given to data at 12 months, as '12 months since surgery'), and unplanned return to theatre for treating a complication resulting directly or indirectly from the primary procedure (such as deep infection or non-union). We assessed the certainty of the evidence for these outcomes using GRADE. MAIN RESULTS: We included 76 studies (66 RCTs, 10 quasi-RCTs) with a total of 10,979 participants with 10,988 extracapsular hip fractures. The mean ages of participants in the studies ranged from 54 to 85 years; 72% were women. Seventeen studies included unstable trochanteric fractures; three included stable trochanteric fractures only; one included only subtrochanteric fractures; and other studies included a mix of fracture types. More than half of the studies were conducted before 2010. Owing to limitations in the quality of reporting, we could not easily judge whether care pathways in these older studies were comparable to current standards of care. We downgraded the certainty of the outcomes because of high or unclear risk of bias; imprecision (when data were available from insufficient numbers of participants or the confidence interval (CI) was wide); and inconsistency (when we noted substantial levels of statistical heterogeneity or differences between findings when outcomes were reported using other measurement tools). There is probably little or no difference between cephalomedullary nails and extramedullary implants in terms of mortality within four months of surgery (risk ratio (RR) 0.96, 95% CI 0.79 to 1.18; 30 studies, 4603 participants) and at 12 months (RR 0.99, 95% CI 0.90 to 1.08; 47 studies, 7618 participants); this evidence was assessed to be of moderate certainty. We found low-certainty evidence for differences in unplanned return to theatre but this was imprecise and included clinically relevant benefits and harms (RR 1.15, 95% CI 0.89 to 1.50; 50 studies, 8398 participants). The effect estimate for functional status at four months also included clinically relevant benefits and harms; this evidence was derived from only two small studies and was imprecise (standardised mean difference (SMD) 0.02, 95% CI -0.27 to 0.30; 188 participants; low-certainty evidence). Similarly, the estimate for delirium was imprecise (RR 1.22, 95% CI 0.67 to 2.22; 5 studies, 1310 participants; low-certainty evidence). Mobility at four months was reported using different measures (such as the number of people with independent mobility or scores on a mobility scale); findings were not consistent between these measures and we could not be certain of the evidence for this outcome. We were also uncertain of the findings for performance in ADL at four months; we did not pool the data from four studies because of substantial heterogeneity. We found no data for health-related quality of life at four months. Using a cephalomedullary nail in preference to an extramedullary device saves one superficial infection per 303 patients (RR 0.71, 95% CI 0.53 to 0.96; 35 studies, 5087 participants; moderate-certainty evidence) and leads to fewer non-unions (RR 0.55, 95% CI 0.32 to 0.96; 40 studies, 4959 participants; moderate-certainty evidence). However, the risk of intraoperative implant-related fractures was greater with cephalomedullary nails (RR 2.94, 95% CI 1.65 to 5.24; 35 studies, 4872 participants; moderate-certainty evidence), as was the risk of later fractures (RR 3.62, 95% CI 2.07 to 6.33; 46 studies, 7021 participants; moderate-certainty evidence). Cephalomedullary nails caused one additional implant-related fracture per 67 participants. We noted no evidence of a difference in other adverse events related or unrelated to the implant, fracture or both. Subgroup analyses provided no evidence of differences between the length of cephalomedullary nail used, the stability of the fracture, or between newer and older designs of cephalomedullary nail. AUTHORS' CONCLUSIONS Extramedullary devices, most commonly the sliding hip screw, yield very similar functional outcomes to cephalomedullary devices in the management of extracapsular fragility hip fractures. There is a reduced risk of infection and non-union with cephalomedullary nails, however there is an increased risk of implant-related fracture that is not attenuated with newer designs. Few studies considered patient-relevant outcomes such as performance of activities of daily living, health-related quality of life, mobility, or delirium. This emphasises the need to include the core outcome set for hip fracture in future RCTs.

Abstract
In unstable pertrochanteric fractures, there are still debates regarding the complications and long-term benefits after internal fixation using short or long cephalomedullary nails. Therefore, a study was developed regarding this idea. From May 2017 to April 2020, 61 patients with unstable (AO 31-A2) and intertrochanteric fractures (AO 31-A3) were surgically operated on. During follow-up, 8 patients were excluded (lost or deceased). A total of 26 patients received internal short nail system fixation and 27 received a long nail system. All cases followed the standard 6-week rehabilitation protocol. Follow-up was at 3, 6 weeks, 3, 6 and 12 months, and clinical and functional assessment were determined by a different surgeon using the Visual Analogue Scale (VAS), Harris Hip Score (HHS) and Functional Ambulation Categories (FAC). A total of 42 (79.2%) had a 31.A2 fracture (21 in the long nail group and 21 in the short nail group) and 11 (20.8%) had a 31.A3 fracture (6 in long nail group and 5 in the short nail group). Surgical time was significantly longer (P<0.05) in the long nail group (an average of 81.38±12.01 min), compared with the short nail group (53.11±8.36 min). Blood loss was significantly higher (P<0.05) in the long nail group (210±12.1 ml) compared to the short nail group (75.4±14.8 ml). No statistical differences were noted regarding tip-apex distance (TAD) and VAS score. At 6 months, HHS was better for the short nail group (84.76±3.68) (P<0.05). Regarding the FAC scale, no significant statistical differences were identified. Cut-out occurred in 2 cases in the short nail group and 1 case from the long nail group. Only 1 peri-implant fracture occurred in a patient with a long cephalomedullary nail. In conclusion, the long cephalomedullary nail requires a longer surgical time and is associated with an increase in intraoperative blood loss without improving the functional outcome after 12 months postoperatively. A larger sample of cases is required to thoroughly analyze the postoperative complications.

Injury 2021; 52:3404-3407. [PMID: 34311957 DOI: 10.1016/j.injury.2021.07.021] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 07/05/2021] [Accepted: 07/10/2021] [Indexed: 02/02/2023]
Abstract
BACKGROUND Tip-apex distance (TAD) of greater than 25 mm increases the risk of cephalomedullary nail (CMN) cutout for trochanteric hip fractures. The Stryker ADAPT navigation system provides intraoperative feedback to guide implant positioning. This study compares lag screw positioning using the ADAPT to conventional methods and investigates if the use of ADAPT impacts operating room efficiency. METHODS Retrospective review of 82 consecutive patients who underwent Stryker Gamma3 CMN for a peritrochanteric hip fracture. Study groups were assigned based on use of ADAPT navigation. Primary outcome was TAD. Secondary outcomes were lag screw position, operative time, and radiation dose. Univariate analysis of covariance was used to compare primary outcome measures, controlling for fracture classification. RESULTS 41 patients were assigned to each group. When comparing ADAPT and conventional groups mean TAD was 14.45±3.68 and 16.41±3.78 mm (p = 0.023). A higher portion of ADAPT nails (85.4% vs 63.4%, p = 0.024) were center- center within the femoral head compared to conventional methods. There were no significant differences with regards to operative time, fluoroscopy time, or radiation dose. CONCLUSION ADAPT navigation provides intraoperative feedback to achieve improved lag screw positioning, leading to improved TAD. The overall improvement in TAD does not likely reach clinical significance. The system requires minimal setup in the operating room, does not impact workflow, and the user interface is straight forward.

Abstract
Background: Intertrochanteric femur fractures, which are common geriatric osteoporotic fractures, have imposed a huge economic and social burden. This study clarified the global status of research on intertrochanteric fractures between 2001 and 2020 and predicted future research trends in this field using bibliometric and visualized studies. Methods: Publications related to intertrochanteric fractures were retrieved from the Web of Science (WoS) database. All studies were published between 2001 and 2020. Bibliometric and co-occurrence analyses were conducted using VoS viewer software. Results: In total, 2,632 studies were retrieved. The number of global publications regarding intertrochanteric fractures increased annually. The United States was the largest contributor, ranking first in total publications, citations, and the H-index. Switzerland had the highest average citation frequency among the 10 countries with the highest number of publications. The journal that published the most articles regarding intertrochanteric fractures was the Injury International Journal of The Care of The Injured, with 290 articles published. This journal also ranked first in the citation frequency. MJ Parker, an author, published the most papers in the field, and the University of California research team at San Francisco contributed the most publications in this field. During the co-occurrence analysis, all keywords were divided into four clusters: internal fixation study, complication study, risk-factor study, and survival and prognosis analysis study. The internal fixation and survival and prognosis analysis studies were predicted as the next hot topics in the field of intertrochanteric fractures. Conclusions: Intertrochanteric fractures are gaining increasing research attention according to the current global trend, and the number of publications regarding intertrochanteric hip fractures will continue to increase. The United States currently publishes the most articles on intertrochanteric fractures. The number of studies related to internal fixation, survival, and prognosis analysis is increasing, suggesting that these topics may become the next research hotspots in the area of intertrochanteric fractures.

Abstract
INTRODUCTION Intertrochanteric (IT) fractures are estimated to burden the healthcare system six billion dollars annually. Previous studies have documented a trend of early-career orthopaedic surgeons favoring intramedullary nails (IMNs) for these fractures, despite multiple randomized controlled trials demonstrating no evidence for improved patient outcomes when compared with sliding hip screws (SHSs). The purpose of this study was to report the trend of implant utilization for IT fracture fixation from 2007 to 2017. METHODS The American Board of Orthopaedic Surgery (ABOS) Part II (oral) database was used to identify IT fractures (International Classification of Diseases, 9th revision, code 820.21 or 820.31, and 10th revision, code S72.14) over a 10-year period (2007 to 2017). The cases were categorized by IMN or SHS fixation by surgeon-reported Current Procedural Terminology codes. Utilization of the devices was analyzed according to year, and the implants were compared for outcomes, complications, and cost. RESULTS As of 2017, 92.4% of IT fractures were being fixed through IMN, representing a 49.1% increase in the number of IMN devices used during the course of this study. SHS had significantly lower medical complication rate (21.3%) and readmittance rate (4.0%) compared with the IMN (medical complication: 26.9%; P < 0.01) (readmittance rate: 5.4%; P = 0.02). SHS also had significantly lower rates of anemia (5.2%) and patient expiration (4.8%) compared with IMN (anemia: 10.2%; P < 0.01) (patient expiration: 6.1%; P = 0.01). Overall surgical complication rates, reoperative rates, and anesthetic complications did not differ between constructs. A cost differential of $671,812 was found from the 2007-projected distribution, which rose to $3,911,211.00 across the entire 11-year duration of the study for the population. DISCUSSION Early-career orthopaedic surgeons continue to use a more expensive implant for IT fractures despite limited evidence for improved outcomes. LEVEL OF EVIDENCE Level III; Retrospective Cohort Study.

Malays Orthop J 2021; 15:115-121. [PMID: 34429831 PMCID: PMC8381670 DOI: 10.5704/moj.2107.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Accepted: 05/24/2021] [Indexed: 11/17/2022] Open
Abstract
INTRODUCTION Both short and long PFNA are employed to treat intertrochanteric fractures. Controversy exists in the choice between the two nails as each implant has specific characteristics and theoretical advantages. This retrospective study seeks to examine the operative complication rates and clinical outcomes of short versus long (Proximal Femoral Nail Antirotation) PFNA in the treatment of intertrochanteric fractures. MATERIAL AND METHODS Between July 2011 and February 2015, 155 patients underwent PFNA insertion. The decision on whether to use a short or long PFNA nail, locked or unlocked, was determined by the attending operating surgeon. Visual Analogue Pain Score (VAS) Harris Hip Scores (HHS), Short-form 36 Health Questionnaire (SF-36) and Parker Mobility Scores (PMS) were collected at six weeks, six months and one year post-operatively. RESULTS A total of 137 (88.4%) patients were successfully followed-up. Forty-two (30.7%) patients received a short PFNA. The patients were similar in baseline characteristics of age, gender, and comorbidities. Operative time was significantly longer in the short PFNA group (62 ±17 mins) versus the long PFNA group (56±17). While the patients in both groups achieved improvement in all outcome measures, there was no significant difference between the groups in terms of HHS (61.0 ±16.0 vs 63.0 ±16.8, p=0.443), PMS (2.3±1.5 vs 2.7±2.1, p=0.545) and VAS (1.7±2.9 vs 1.8 ±2.2 p=0.454). There were 3 (7.1%) and 7 (7.4%) complications in the short versus long PFNA group, respectively. CONCLUSION Both short and long PFNA had similar clinical outcomes and complication rates in the treatment of intertrochanteric fractures in an Asian population.

Abstract
Purpose To evaluate clinical-functional and radiologic outcomes of elderly patients with an unstable intertrochanteric femur fracture treated with a wedge wing in the lag screw. Materials and Methods Forty-eight patients treated with the Dyna Locking Trochanteric nail (DLT nail) to resolve an unstable intertrochanteric femur fracture were reviewed retrospectively. Based on AO/OTA classification, Fracture 31-A2 (34 cases) and 31-A3 (14 cases) were included in the analysis. We measured the femoral neck-shaft angle, tip-apex distance (TAD), Cleveland index, sliding distance of the lag screw, and time to the fracture union. The Harris Hip Score and Paker and Palmer's mobility score for clinical evaluation were used. Results The mean follow-up period was 21.4 months (range, 12–34 months). The postoperative state of reduction was good in 28 cases and acceptable in 20 cases. The mean TAD was 20.5 mm. The position of the lag screw was center-center in 30 cases and center-inferior in 18 cases. The mean sliding distance of the lag screw was 3.4 mm at the last follow-up. The mean union time was 4.5 months. Two cases had complications which included a cut-out (1 case) and non-union (1 case). The mean Harris Hip Score was 86.5±8.3 (range, 76–90). Walking ability in 34 of the cases (70.8%) at last follow-up was similar to that prior to fracture. Conclusion Functional and radiological outcomes are satisfactory using the DLT nail in the treatment of elderly patients with unstable intertrochanteric fractures; however, wedge wing in the lag screw does not prevent implant-related complications.

Abstract
Objective To investigate the occurrence, treatment, and effectiveness of peri-implant refracture after intramedullary nail fixation for intertrochanteric fractures. Methods The clinical data of 16 patients with peri-implant refracture after intramedullary nail fixation for intertrochanteric fractures who met the inclusion criteria between April 2014 and November 2019 were retrospectively analyzed. There were 7 males and 9 females with an average age of 78.4 years (range, 65-93 years). The 14 cases of initial intertrochanteric fractures were classified according to the classification of AO/Orthopaedic Trauma Association (AO/OTA): 5 cases of type A1, 7 cases of type A2, and 2 cases of type A3; the other 2 cases were intertrochanteric combined with subtrochanteric fractures (Seinsheimer type Ⅴ). According to the classification of peri-implant refracture which was proposed by Chan et al., there were 10 cases of type 1 (6 cases of type 1A, 3 cases of type 1B, 1 case of type 1C) and 6 cases of type 2 (4 cases of type 2A and 2 cases of type 2B). The average interval between refracture and initial surgery was 14.6 months (range, 1-52 months). The incidence of peri-implant refracture in short nail group (the length of intramedullary nail used in initial surgery≤240 mm) was 1.92% (11/573), while the incidence of long nail group (the length of intramedullary nail used in initial surgery≥340 mm) was 1.66% (5/301), showing no significant difference between the two groups ( χ 2=0.073, P=0.786). The peri-implant refractures were revised with extended intramedullary nail (5 cases) or fixed with additional limited invasive stabilization system (11 cases). Results The average operation time was 115.8 minutes (range, 78-168 minutes) and the average intraoperative blood loss was 283.1 mL (range, 120-500 mL). One patient died of myocardial infarction at 3 months after operation, and the other 15 patients were followed up 9-46 months (mean, 16.8 months). The peri-implant refractures healed at 14-20 weeks (mean, 16.4 weeks) after operation. There was no complications such as incision infection, nonunion, internal fixator loosening and rupture, screw cutting-out, and the second refracture during the follow-up. At last follow-up, all injured limbs regained walking function, and the Hospital for Special Surgery (HSS) score was 56-92 (mean, 80.2). The results were classified as excellent in 2 cases, good in 10, fair in 2, and poor in 1, with the excellent and good rate of 80%. Conclusion Stress concentration at the tip of initial intramedullary nail and distal interlocking screw aera is the main cause of peri-implant refracture after intramedullary nail fixation for intertrochanteric fractures. Revision with extended intramedullary nail or fixation with limited invasive stabilization system according to the length of initial intramedullary nail and the type of refracture can get satisfactory effectiveness.

Biomechanical analysis of peri‑implant fractures in short versus long cephalomedullary implants following pertrochanteric fracture consolidation. Injury 2021; 52:60-65. [PMID: 32972726 DOI: 10.1016/j.injury.2020.09.037] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Accepted: 09/13/2020] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Pertrochanteric femur fracture fixation with use of cephalomedullary nails (CMN) has become increasingly popular in recent past. Known complications after fracture consolidation include peri‑implant fractures following the use of both short and long nails, with fracture lines around the tip of the nail or through the interlocking screw holes, resulting in secondary midshaft or supracondylar femur fractures, respectively. Limited research exists to help the surgeon decide on the use of short versus long nails, while both have their benefits. The aim of this biomechanical study is to investigate in direct comparison one of the newest generations short and long CMNs in a human anatomical model, in terms of construct stability and generation of secondary fracture pattern following pertrochanteric fracture consolidation. METHODS Eight intact human anatomical femur pairs were assigned to two groups of eight specimens each for nailing using short or long CMNs. Each specimen was first biomechanically preloaded at 1 Hz over 2000 cycles in superimposed synchronous axial compression to 1800 N and internal rotation to 11.5 Nm. Following, internal rotation to failure was applied over an arc of 90° within one second under 700 N axial load. Torsional stiffness as well as torque at failure, angle at failure, and energy to failure were evaluated. Fracture patterns were analyzed. RESULTS Outcomes in the study groups with short and long nails were 9.7 ± 2.4 Nm/° and 10.2 ± 2.9 Nm/° for torsional stiffness, 119.8 ± 37.2 Nm and 128±46.7 Nm for torque at failure, 13.5 ± 3.5° and 13.4 ± 2.6° for angle at failure, and 887.5 ± 416.9 Nm° and 928.3 ± 461.0 Nm° for energy to failure, respectively, with no significant differences between them, p ≥ 0.17. Fractures through the distal locking screw holes occurred in 5 and 6 femora instrumented with short and long nails, respectively. Fractures through the lateral entry site of the head element were detected in 3 specimens within each group. For short nails, fractures through the distal shaft region, not interfacing with the implant, were detected in 3 specimens. CONCLUSION From a biomechanical perspective, the risk of secondary peri‑implant fracture after intramedullary fixation of pertrochanteric fractures is similar when using short or long CMN. Moreover, for both nail versions the fracture pattern does not unexceptionally involve the distal locking screw hole.

Le QT. Effectiveness in the Treatment of Intertrochanteric Fracture in Geriatric Patients by A Novel Prototype Carbon Composite External Fixator. Med Arch 2021; 75:122-132. [PMID: 34219872 PMCID: PMC8228569 DOI: 10.5455/medarh.2021.75.122-132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/09/2022] Open
Abstract
Background: Intertrochanteric fracture is a common injury in seniors. Senior patients taking surgical interventions suffer from prolonged bed-rest complications such as pressure ulcer, thromboembolism, or pneumonia, which may lead to high mortality rate. A treatment using external fixators is, therefore, recommendable, and has shown satisfactory outcomes such as early weight-bearing, short hospitalization time and quick union time. Fracture treatments in Vietnam mainly use metal and imported fixation, raising concerns of compatibility and financial issues from patients. Objective: This study investigated the in vivo effectiveness in treating an intertrochanteric fracture in Vietnamese geriatric patients by a novel prototype carbon composite external fixator (whose shaft screws near the fracture site) and an available stainless steel external fixator (shaft screw far from the fracture site) already used in Vietnam. Methods: Fifty-five patients treated with the metal fixator and 54 patients treated with the composite fixator – all aged 60 – 99 – were monitored for treatment results until one year after surgery. Results: The results demonstrated the external fixator’s effectiveness, especially the composite prototype, which minimized blood loss, shortened operation time, reduced pain, and provided stable fixation that promoted proper bone union. Conclusion: The novel composite fixator prototype in this study was also superior to the current metal fixator in many aspects. Proper application of this method could prove its effectiveness in the surgical cure for fracture in older people. It should be a viable choice for intertrochanteric fracture treatment for senile people in Vietnam.

Abstract
Introduction: As the geriatric population increases, the incidence of intertrochanteric fractures (ITF) has also increased significantly. There are various modalities to treat these fractures. In this study our aim is to analyse outcomes of Proximal Femoral Nail (PFN) in comparison to those of Dynamic Hip Screw (DHS) for the treatment of ITF. Materials and Methods: This study was carried out during 2017–20. 150 patients of unstable ITF (AO type 31-A2, 31-A3) in elderly were randomly divided into two groups of 75 each and were treated either by DHS or PFN and were followed up regularly. Results: The results were compared between the groups and statistical analyses were performed. The results were assessed with Harris Hip Score(HHS) & Parker Palmer mobility score (PPMS) which were better in PFN group. Conclusion: PFN is a better fixation device for unstable ITF (31 A2 and 31 A3) in elderly patients.

Abstract
OBJECTIVE To compare antirotator proximal femoral nail (A-PFN) with antirotator dynamic hip screw (A-DHS). METHODS Fourteen proximal femur models with type 31/A2 fracture, according to the AO Foundation/Orthopaedic Trauma Association (AO/OTA) classification, were separated into two groups. Group 1 bones (n = 7) were fixed with A-PFN and Group 2 (n = 7) with A-DHS. A 5 mm/min axial load was applied to femur heads using a testing device. RESULTS Two of the seven models in the A-PFN group fractured at the proximal, and the other five at distal locking screw level. All models in the A-DHS group fractured at the tightened distal screw region. The median fracture load for the A-PFN group was 132.1 N (97.1-173.69 N range), and for the A-DHS group it was 81.7 N (75.15-89.12 N range). CONCLUSION A-PFN-treated unstable intertrochanteric fractured models resisted to higher levels of axial load than the A-DHS-treated group, with statistically significant difference. However, clinical studies are required to support these results. Level of Evidence V, Biomechanical study.

Abstract
Background There are several surgical methods to treat intertrochanteric fracture: dynamic hip screw (DHS), compression hip screw (CHS), percutaneous compression plate (PCCP), Medoff sliding plate, less invasive stabilization system (LISS), Gamma nail, proximal femoral nail (PFN), and proximal femoral nail anti-rotating (PFNA). We therefore conducted a network meta-analysis to compare eight surgical interventions, including DHS, CHS, PCCP, Medoff sliding plate, LISS, Gamma nail, PFN, and PFNA, to provide the optimal surgical intervention for intertrochanteric fracture. Methods An electronic search of 4 databases (PubMed, Embase, Cochrane library, and Web of Science) from inception to July 2020. Two or more of the eight surgical interventions, including the DHS, CHS, PCCP, Medoff sliding plate, LISS, Gamma nail, PFN, and PFNA, for intertrochanteric fracture were included. The methodological quality of the included studies was assessed using the Cochrane Collaboration risk of bias (ROB) tool. Network meta-analysis was conducted by using R-3.5.1 software with the help of package “gemtc”. The odd ratios (ORs) with 95% credibility interval (CrI) were used to assess complications and standard mean difference (SMD) with 95% CrI to calculate the continuous outcomes (operative time, intraoperative blood loss, and Harris hip score). Surfaces under the cumulative ranking curves (SUCRA) were used to rank the intervention. Results A total of 36 RCTs were included in this study. The results of this network meta-analysis showed that, compared with the CHS and DHS group, PFNA exhibited a beneficial role in reducing the blood loss (SMD, 152.50; 95% CrI, 72.93 to 232.45; and SMD, 184.40; 95% CrI, 132.99 to 235.90, respectively). PFNA achieved the lowest value for the surface under the cumulative ranking curve (SUCRA) for the blood loss (SURCA = 0.072) and highest of Harris hip score (SURCA = 0.912). PCCP may have the lowest probability of the operative time (SURCA = 0.095). There were no significant differences among the eight surgical procedures in complications. Conclusion PFNA technique is the optimal treatment method for intertrochanteric fracture. Larger, longitudinal RCTs addressing current limitations, including sources of bias, inconsistency, and imprecision, are needed to provide more robust and consistent evidence.

Abstract
OBJECTIVES There is no definitive evidence to guide clinicians in their decision-making for implant choice regarding long or short intramedullary nails for unstable fracture patterns. Historically short nails were associated with higher rates of perisprothetic fractures which seem to have improved with newer designs. Long intramedullary nails have higher blood loss and time under anesthesia. The purpose of this study was to assess stability of long and short intramedullary nail constructs in unstable intertrochanteric fracture patterns to better elucidate if unstable intertrochanteric fractures are amenable to treatment with short intramedullary nails. METHODS This study utilized composite model femurs which were assigned to either a comminuted or reverse obliquity fracture pattern, then subsequently assigned to implantation with either a long or short intramedullary nail. All the samples were reamed to the level of the distal femur and instrumented with the appropriate nail. Axial and torsional stiffness as well as axial load to failure values were determined using a servohydraulic loading system. RESULTS Short nail constructs exhibited significantly greater axial stiffness in A1 fractures and torsional stiffness in A3 fractures when compared with long nails. There was no significant difference between axial load to failure between long nails and short nails. DISCUSSION We found no significant difference in axial load to failure values between long and short intramedullary nail fixation in 2 unstable intertrochanteric fracture patterns in a composite femur model. Short nails exhibited greater stiffness in axial loads in the A1 pattern and torsional stiffness in the A3 pattern. This suggests short or long intramedullary nails could be appropriately employed for fixation of unstable intertrochanteric hip fracture patterns.

Abstract
OBJECTIVES This study compares the intraoperative and postoperative outcomes of the traditional technique of femoral canal reaming to placement of an unreamed 10-mm nail. DESIGN Retrospective cohort study. SETTING Academic Level I Trauma Center, Southeastern US. PATIENTS/PARTICIPANTS Intertrochanteric femur fractures treated with a CMN (January 2016-December 2018) were retrospectively identified. Inclusion criteria were as follows: low-energy mechanism, at least 60 years of age, and long CMN. Exclusion criteria were as follows: short CMN, polytrauma, and subtrochanteric fractures. OUTCOME MEASUREMENTS Records were reviewed for demographics, hematologic markers, transfusion rates, operative times, and postoperative complications. Variables were assessed with a χ or Student T-test. Significance was set at 0.05. RESULTS Sixty-five patients were included (37 reamed and 28 unreamed), with a mean age of 76.2 years and mean body mass index of 25.1. Between the reamed and unreamed groups, respectively, mean nail size was 11.0 (SD 1.1) and 10.0 (SD 0.0), P < 0.001; mean blood loss was 209.1 mL (SD 177.5) and 195.7 mL (SD 151.5), P = 0.220; 55% (21/38), and 43% (12/28) were transfused, P = 0.319; operative time was 98.2 (SD 47.3) and 81.5 minutes (SD 40.7); P = 0.035. Changes in hemoglobin/hematocrit were not significant between the study groups. Two patients from the reamed group experienced implant failure due to femoral head screw cut out and returned to the operating room. Two patients from the unreamed group returned to operating room for proximal incision infection, without implant removal. One reamed patient and 2 unreamed patients died before 6-month follow-up. CONCLUSIONS Unreamed CMNs for geriatric intertrochanteric femur fractures provide shorter operative times with no difference in perioperative complications. Both reamed and unreamed techniques are safe and effective measures for fixation of these fractures. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
PURPOSE The dynamic hip screw (DHS) is widely used for fixing intertrochanteric femur fractures. A porous bionic DHS was developed recently to avoid the stress concentration and risk of post-operative complications associated with titanium alloy DHSs. The purpose of this study was to compare the effects of traditional titanium alloy, bionic titanium alloy, and bionic magnesium alloy DHS fixation for treatment of intertrochanteric fractures using finite element analysis. METHODS A three-dimensional model of the proximal femur was established by human computed tomography images. An intertrochanteric fracture was created on the model, which was fixed using traditional and porous bionic DHS, respectively. The von Mises stress, maximum principal stress, and minimum principal stress were calculated to evaluate the effect of bone ingrowth on stress distribution of the proximal femur after fixation. RESULTS Stress concentration of the bionic DHS model was lower compared with traditional DHS fixation models. The von Mises stress, maximum principal stress, and minimum principal stress distributions of bionic magnesium alloy DHS models improved, along with simulation of the bone healing process and magnesium alloy degeneration, assumed to biodegrade completely 12 months post-operatively. The distribution of maximum principal stress in the secondary tension zone of the bionic DHS model was close to the intact bone. In the minimum principal stress, the region of minimum stress value less than - 10 MPa was significantly improved compared with traditional DHS models. CONCLUSION The bionic magnesium alloy DHS implant can improve the stress distribution of fractured bone close to that of intact bone while reducing the risk of post-operative complications associated with traditional internal fixations.

Abstract
BACKGROUND Various internal fixation methods have been used to treat proximal femur fractures and occasionally the fixation material is removed. However, nationwide trends of hardware removals are not known. Thus, this study investigated the hardware removal rates after proximal femur fractures in Finland during 1997-2016. MATERIALS AND METHODS Finnish adults aged 18 years or older in 1997-2016 formed the basic study population. From the National Hospital Discharge Register patients with trochanteric femur fracture treated with an intramedullary nail (IMN) or dynamic hip screw (DHS), and patients with femoral neck fracture treated with screw fixation, were included. Hardware removal and secondary prosthesis rates were assessed. RESULTS Altogether 41,253 patients underwent proximal femoral fracture fixation surgery in Finland in 1997-2016. Of these, 16,152 were DHS surgery and 15,724 IMN surgery and 8491 underwent screw operation of femoral neck fracture. The total removal rates of DHS and IMN were 5.5% and 5.4%. The total removal rate of screw fixations of the femoral neck was higher, 18.5%. The total removal rates during the first 3 years after the IMN more than halved in 1997-2013, from 7.6% to 3.7%, whereas the removal rate of the DHS or screw fixation of femoral neck fractures did not show consistent trend. The rate of secondary prosthesis operations following DHS and IMN was low (1.8% for both). This was in clear contrast to the prosthesis rate following screw fixations of the femoral neck (7.2%). CONCLUSIONS IMN operations largely replaced DHS operations in trochanteric fractures of the proximal femur in Finland in 1997-2016. The removal and secondary prosthesis rates of the DHS and IMN were clearly lower than the corresponding rates after screw fixations of the femoral neck fracture.

Abstract
The purpose of the current study was to present the authors’ experiences with the long intramedullary Gamma nail in the treatment of patients with complex femoral fractures. Th is retrospective study included 48 patients with complex femoral fractures. All patients had received fracture fixation treatments with long intramedullary Gamma nails from January 2007 to December 2015. The complex fractures of all patients were classified into 3 types, according to the anatomical locations of the fractures. Type I included combined fractures of the shaft and the proximal femur. Type II included segmental fractures. Type III included combined fractures of the shaft and distal femur. According to the Harris Hip Score, 85.4% of our patients had excellent and very good functional outcomes of the operative procedure. Complications occurred in 7 (14.58%) patients. The most common complications occurred in patients with combined fractures of the shaft and distal femur (50%). Based on the findings of this study, we conclude that the clinical and radiological results after the treatment of complex femoral fractures with the long intramedullary Gamma nail show good outcomes, with a high rate of bone union and minimal soft tissue damage. Experience with this procedure is important to prevent and minimise technical complications.

Abstract
INTRODUCTION Intra- and post-operative femoral shaft fractures related with nailing remain of concern. Although manufacturers have sought to solve the problem by providing distally slotted nails, it is not clear that these implants reduce fractures. We compare two distally slotted proximal femoral nails [trochanteric nail (TRON) and proximal femur intramedullary nail (PROFIN)]. PATIENTS AND METHODS The medical records of 195 hips treated with TRONs (distally slotted in four places in the sagittal and coronal planes) and 583 hips treated with PROFINs (distally slotted in two places in the coronal plane) in two institutes were retrospectively evaluated. The inclusion criteria were follow-up for at least 6 months; pertrochanteric fractures and age over 55 years. RESULTS In total, 161 hips in the TRON group and 512 hips in the PROFIN group were included. The mean follow-up time was 28.5 (range: 6-84) months in whole group. The demographic characteristics of the groups were similar. Only 2 intraoperative shaft and 3 proximal lateral cortex fracture was detected in PROFIN group, there wasn't any postoperative fracture. Four proximal lateral cortex and 2 femur shaft fractures were detected in TRON group (one during operation and one at postoperative 8th month after a fall at pedestrian way). CONCLUSIONS Distal cephalomedullary nail slotting prevented intra- and post-operative femoral fractures. A distal slot 50 mm in length may increase nail elasticity and reduce nail tip stress to a greater extent than a 30-mm slot. Distal slotting in both the sagittal and coronal planes afforded no advantage compared to coronal slotting only. LEVEL OF EVIDENCE Level III retrospective study.

Abstract
INTRODUCTION Intertrochanteric fracture is one of the most common and severe fractures occurring in the elderly population. We conducted a randomized prospective study to compare the functional and radiological outcome of Proximal Femoral Nail anti-rotation-Asia(PFNA-II) and Dynamic Hip screw (DHS) used in fixation of stable (AO type 31 A1-A2.1) intertrochanteric fractures in elderly. METHODS 60 elderly patients with stable intertrochanteric fractures treated with DHS and PFNA-II between August 2014 to Dec 2016 were enrolled in the study. Intraoperative variables-surgical time, blood loss, fluoroscopy time and post-operative variables-union rate, change in neck shaft angle(NSA), functional outcome in terms of Modified Harris Hip Score(HHS) & SF-12, complication rate and mortality at one year were studied and compared between both the groups. RESULTS The mean age of patients in our study was 70.96 years. We found patients treated with DHS required significantly longer surgical time and had more blood loss compared to PFNA-II group. However, there was no significant difference in both the groups in terms of intra-operative fluoroscopy time, change in neck shaft angle, union rate, complication rate and Modified Harris Hip Score & SF-12 at three months; six months and one year follow-up. CONCLUSIONS Both DHS and PFNA-II can be used effectively in the treatment of elderly patients with stable intertrochanteric fracture with comparable outcome. However, in high-risk elderly patients requiring shorter surgical time and less blood loss, PFNA-II can be used.

Abstract
OBJECTIVE To compare functional and clinical outcomes in patients with pertrochanteric hip fractures treated with either a short (SN) or long (LN) cephalomedullary nail. DESIGN Prospective, randomized. SETTING Clinical investigation was performed at the Mayo Clinic's Level 1 Trauma Center in Rochester, MN. PATIENTS/PARTICIPANTS Two hundred twenty patients with intertrochanteric fractures were prospectively randomized to an SN or LN cohort. A total of 168 patients (SN, n = 80; LN, n = 88) had a mean follow-up of 13.9 months. Fifty-two patients did not meet the minimum 3-month follow-up. Demographics were comparable between the cohorts. MAIN OUTCOME MEASURES The primary outcome measurement was functional outcome evaluated by Short Form (SF-36) and Harris Hip scores (HHS) at 3 months. Secondary outcomes included implant failure, peri-implant fracture, mortality, operative time, estimated blood loss, and reoperation. RESULTS SN and LN cohorts were comparable in all aspects of the SF-36. There was a clinically insignificant difference in the HHS between cohorts. Patients treated in the SN cohort experienced shorter operative times but did not differ in tip-to-apex distance or subtrochanteric fracture extension. There was no difference in implant cutout, deep surgical site infection, or peri-implant fractures. CONCLUSIONS Patients treated with SNs or LNs for pertrochanteric femur fractures experienced comparable functional outcomes as measured by SF-36 and HHS. When compared with the LN cohort, SN patients experienced no difference in peri-implant fracture or lag-screw cutout and tolerated up to 3 cm of subtrochanteric fracture line extension. LEVEL OF EVIDENCE Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Three techniques to avoid malalignment in proximal femoral fractures managed with cephalomedullary nails, have been described. Issues related to rotational mismatch at fracture site, central placement of lag screw in femoral head neck fragment and limb rotation restoration have been addressed. We believe these simple techniques can help in minimizing malreduction in proximal femur fractures and result in favourable outcomes.

Eur J Trauma Emerg Surg 2019; 46:955-962.

Abstract
INTRODUCTION Third-generation nails for the management of unstable trochanteric fractures were evaluated with regard to outcomes. PATIENTS AND METHODS A prospective observational study comparing the Gamma 3 nail and the Proximal Femoral Nail Antirotation (PFNA) in 106 unstable trochanteric fractures confirms the recently reported low intra- and postoperative complication rates from retrospective cohort studies. RESULTS Studies of same generations of both intramedullary nail systems did not reveal significant differences in intra- or postoperative complications. Intraoperative dislocation during nail insertion occurred 7 times for the Gamma nail and 9 times for the PFNA. The standard PFNA had to be exchanged intraoperatively for a shorter one on two occasions. Superficial wound healing disorders and hematoma requiring revision were observed in four patients in the Gamma 3 nail group and in three patients in the PFNA group. No deep infections were documented. Mechanical complications required revision in four patients (7.5%) after Gamma nailing and in two patients (3.8%) after PFNA. Postoperative rotation of the head-neck fragment was observed for the Gamma nail in three patients, not in the PFNA group. This was not statistically significant (p = 0.08). There were neither incidences of cut out without renewed trauma nor intraoperative fracture or postoperative femoral fracture. Nonunion affected 1 of 18 patients in late follow-up (p = 0.3) in the Gamma 3 nail group. DISCUSSION The Gamma 3 nail and the PFNA yielded comparable clinical results and significantly improved outcomes for unstable trochanteric fractures compared to older nail generations.

Abstract
Objective: We investigated whether elderly patients treated for a proximal
femoral fracture would be able to return home. Patients and Methods: The subjects of this study were 834 patients. We
defined the acute care hospital group as patients who returned home from the acute care
hospital and the kaihukuki group as patients who were transferred from an acute care
hospital to a rehabilitation hospital. We recorded the proportion of patients who returned
home. We also analyzed walking ability and the Barthel index (BI) of patients. Results: After 2013, the proportion of patients who returned home from the
acute care hospital fell below 20%. The proportion of patients who returned home from the
kaihukuki hospital stayed within the 75–85% range. The BI before injury and at discharge
was 86 and 76 points, respectively, in the acute care hospital group. The acute care
hospital group included patients who walked without an aid before the injury or when
leaving the hospital. In the kaihukuki group, the BI before an injury, at admission, and
at discharge from the rehabilitation hospital was 85, 56, and 74 points, respectively. In
the kaihukuki group, the ability of patients to walk recovered more slowly than that of
patients in the acute care hospital group. Conclusion: Walking ability and BI are important factors for determining
whether patients with a proximal femoral fracture are able to return home.

Optimising the tip-apex-distance in trochanteric femoral fracture fixation using the ADAPT-navigated technique, a longitudinal matched cohort study. Injury 2019; 50:744-751. [PMID: 30782395 DOI: 10.1016/j.injury.2019.02.010] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2018] [Revised: 01/14/2019] [Accepted: 02/12/2019] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The annual incidence of proximal femoral fractures is 100-150/100,000 and continues to increase with an aging population. Cut-out of hip screws after fracture fixation has been quoted as 8% in the literature. The tip-apex distance (TAD) is the strongest predictor for cut-out after operative fracture stabilisation. The aim of this study was to evaluate the novel ADAPT system (Adaptive Positioning Technology, Stryker, USA), a navigation device for intramedullary nailing of trochanteric fractures and its effect on optimising the TAD. This is the first clinical study to evaluate this new technology. METHODS The study group of 36 consecutive patients with a pertrochanteric fracture underwent intramedullary nailing for fracture fixation using ADAPT technology, while the matched control group underwent conventional Gamma-3-nailing. Matching criteria included fracture classification, gender and age. We measured the operative time and the postoperative TAD in anteroposterior (AP) and lateral radiographs of the 72 patients. RESULTS The mean TAD using ADAPT was 16.9 mm (range 8.4-33.7 mm) compared with 24.9 mm (range 14.6-40.2 mm) in the reference group treated without ADAPT. Using the ADAPT system significantly improved (p < 0.0005) the accuracy of lag screw placement but had no effect on operating time in fixation of femoral pertrochanteric fractures. CONCLUSION Working with the novel ADAPT system for positioning the lag screw using the Gamma-3-nail led to a statistically highly significant reduction of the TAD compared to the reference group (p < 0.001). The ADAPT system proved to be a very useful device in achieving higher surgical standards for the treatment of trochanteric fractures with intramedullary nailing. It enables higher accuracy in screw positioning and therefore better placement of the implant.

Abstract
BACKGROUND AND PURPOSE To compare the radiological and clinical results of sliding hip screw (SHS) fixation with or without a Trochanteric Support Plate (TSP) on unstable three-or-more-part trochanteric fractures. METHODS A randomized prospective non blinded study of one hundred patients with trochanteric fractures; Evans-Jensen type 3, 4 and 5, reduced and fixed with SHS. Patients were randomized into two study groups; with or without TSP supplementation ('TSP' and 'NoTSP' groups). Radiologic measurements of the hip in the frontal plane (primary outcome), including fracture movement, nonunion and loss of fixation were measured, as well as pain, ambulation, mobility, institution residence, complications and death, twelve months post operatively (secondary outcomes). RESULTS At one-year follow-up four patients in the TSP and ten patients in the NoTSP group had either died or been lost in follow-up. Within this period, forty-three fractures healed and three had a loss of fixation in the TSP group; thirty-nine fractures healed and one had a loss of fixation in the NoTSP group. Frontal X-rays showed fracture subsidence on average 1 mm less in the TSP group compared to the NoTSP group. This difference was negligible, as was the difference in all subgroups, in fixation failure/cutout, modified Merle d'Aubigne Postel scores (measuring function and pain), institution residence, complications and death between the groups. INTERPRETATION This study cannot confirm that TSP has any beneficial effects on unstable three-or-more-part trochanteric fractures. If any effect at all, the difference is most likely slight and clinically irrelevant.

Abstract
BACKGROUND The γ‑nailing system is a widespread intramedullary therapeutic option that has been used for intertrochanteric and subtrochanteric fractures since the late 1980s; however, some reports from the 1990s describing femoral shaft fractures questioned the indications for this system in simple fracture types. Due to increasing numbers of patients treated with this system, the complication rate is continuously falling as confirmed by many recent studies. OBJECTIVE Between 2008 and 2013 a total of 1500 operations using the γ‑nailing system were performed at this traumatology department. The standard 200 mm nail was used in 1290 cases and the extended system available from 340 to 440 mm in 210 cases. The aim of this study was to record the excellent results using the standard γ‑nailing system and to confirm the indications of the long intramedullary nailing system (Gamma3®) also for use in complex intertrochanteric and subtrochanteric fractures. MATERIAL AND METHODS All 1500 patients were retrospectively analyzed. Information on epidemiological data, intraoperative and postoperative complications and patient outcome was retrieved from the digital patient medical history. All available radiographs were assessed by a single traumatologist. RESULTS The results showed a low complication rate of 5% for surgical complications, mainly caused by cutting out in 34.66%, followed by hematomas in 21.33% and fractures of the nail in 16%. A comparison of the standard and long nailing systems could be carried out, showing a complication rate of 3.64% for the standard system compared to 13.33% for the long γ‑nail system. CONCLUSION The γ‑nailing system is a safe treatment option for trochanteric femoral fractures and failure of the implant is associated with high biomechanical forces in unstable fractures. A low complication rate is linked to a thorough surgical technique under consideration of a correct positioning of the implant.

Abstract
Objective: In this study, 14-month clinical outcomes of the endoprosthesis and pertrochanteric external fixator application are retrospectively evaluated in elderly patients with pertrochanteric fractures. Patients and Method: A total of 45 patients of 65 years old and older (25 females and 20 males) with a mean age of 78.1, who were treated due to intertrochanteric femur fracture between November 2013 and December 2014 and whose controls could be made were included in this study. The deaths that occurred within the postoperative 1 year were not included in the study. 28 patients with endoprosthesis as Group I, and 17 patients with pertrochanteric external fixator as Group II were evaluated. Results: Table 2 shows the clinical evaluation results of the patients according to different criteria by the groups. The mean operation time was 45 min in Group I and 20 min in Group II. The external fixator application time is significantly shorter. The mean hospital stay was 14 days for Group I and 10 days for Group II. The hospital stay period of the external fixator group is 4 days shorter. While 7 patients were taken into the intensive care unit in Group I postoperatively, only 1 patient was taken into the same unit in Group II. This difference was significantly in favor of the external fixator group. While 14 patients in Group I needed a preoperative and postoperative blood transfusion, no patient needed blood transfusions in Group II. External fixator application is significantly more advantageous in terms of patient hemodynamics. The mean time to postoperatively move the extremity independently in the bed was 24 hours in Group I and 36 hours in Group II. All patients were exposed to the Harris hip scoring in the postoperative 12. month (the fixator was removed for the external fixator group). Conclusion: In addition to internal fixation options and endoprosthesis applications in elderly intertrochanteric femoral fractures, an external fixator may also be a good treatment alternative with appropriate patient selection and proper application in accordance with the technique thanks to its short surgical time, less blood loss and easy applicability.

Abstract
This case report describes the management and therapeutic solution for the treatment of subtrochanteric non-union in a patient with hip arthrodesis. Two techniques can be used in the treatment of these non-unions: a closed intramedullary nailing or an open technique with plate, preferably carried out together with cortical bone graft. The surgical technique varies depending on the fixation method used for the initial treatment of the fracture and on the characteristics of the non-union. We report an unusual case of a patient who started her long clinical history more than 40 years ago with a septic arthritis of the hip healed in arthrodesis. 35 years later, after having undergone various surgeries, she fractured the proximal femur, which had to be operated seven times before reaching healing. Satisfactory outcomes were finally obtained. Arthrodesis proved to be the main cause of failed healing and of the recurrent non-union.

Abstract
INTRODUCTION Few clinical studies have analyzed the utility of distal interlocking screws in stable and unstable intertrochanteric fractures treated with intramedullary devices. We performed a prospective analysis comparing short unlocked versus short dynamic and short static distal locked intramedullary nails. MATERIALS AND METHODS Nine level-II trauma centres were involved in the study. 240 patients over the age of 65 with a stable (AO/OTA 31-A1) or unstable intertrochanteric fracture (AO/OTA 31-A2) were prospectively investigated. The same type of nail was used in every patient. Patients were randomly divided into 3 groups according to the type of distal locking used. Intra-operative variables were examined and patients were followed clinically and radiographically at 1, 3, 6, 12 months postoperatively. All complications were recorded. RESULTS A total of 212 patients completed 1 year of follow-up visits. In the Unlocking Group (UG) the operation time, blood loss, fluoroscopy time, total length of incision were significantly decreased compared to both the Dynamic Group (DG) and the Static Group (SG) (p < 0.05). Conversely, no reliable differences in intraoperative variables were noted between the Dynamic Group and the Static Group (p > 0.05). In terms of time of fracture union we found no differences among the three Groups (p > 0.05). Moreover, no cases of limb shortening >1 cm or varus collapse were detected in any group. The 3 Groups were similar in terms of HHS, SF-12 and Barthel index results at 1-year follow-up (p > 0.05). Finally, no significant differences were demonstrated across the three Groups in terms of major complications. CONCLUSIONS This clinical study further confirms the hypothesis that short intramedullary nails do not need to be locked for stable and unstable intertrochanteric fractures.
