Abstract
Removal of a retained and osseointegrated intramedullary femoral nail can represent a considerable problem, especially in the case of contemporary total hip arthroplasty or, even worse, in the case of revision hip arthroplasty. Usually, complex and invasive surgical techniques are required to remove incarcerated Kuntscher nails. We described a case of an incarcerated Kuntscher nail, inserted 39 years before, in a 75-year-old woman waiting for a revision total hip arthroplasty of a failed metal-on-metal hip resurfacing. A CT-based custom-made extra-long trephine reamer was designed and successfully used to easily extract the nail, leaving the proximal femur before a revision hip arthroplasty.

Abstract
CASE A 70-year-old man with a year-long history of arthritic pain in his left hip presented to our clinic. He had a left intertrochanteric hip fracture 6 years ago, fixed with an open reduction internal fixation with a cephalomedullary nail. He underwent a conversion Birmingham Hip Resurfacing (BHR) with removal of the proximal helicoidal blade and retention of the intramedullary nail. At 7-year follow-up, the patient reported satisfactory clinical outcomes and excellent radiographic fixation. CONCLUSION This case highlights using conversion BHR in patients with post-traumatic arthritis with retained femoral hardware as an alternative to conventional total hip arthroplasty.

Abstract
Salvage conversion hip arthroplasty is a viable solution to restore function and reduce pain after failed intertrochanteric hip fracture fixation. Our primary objective was to assess early outcomes achieved with primary cementless metaphyseal-engaging femoral stems for conversion hip arthroplasty compared with revision diaphyseal-engaging stems. This was a retrospective review of 70 patients with failed intertrochanteric hip fractures subsequently managed with conversion total hip arthroplasty or hemiarthroplasty. Thirty-five patients who underwent conversion using a primary cementless stem were compared with 35 patients who underwent conversion using a revision stem. The groups were similar regarding sex, body mass index, American Society of Anesthesiologists classification, preoperative diagnosis, and implants removed. Clinical and radiographic outcomes and complications were compared over a mean follow-up of 6 years. The primary stem cohort had a shorter mean hospital stay (3.03 vs 4.34 days, P=.028). There were no significant differences between the primary and revision cohorts regarding mean time to conversion (2.26 vs 1.75 years, P=.671), operative time (127 vs 131 minutes, P=.611), incidence of discharge to home (54.3% vs 37.1%, P=.23), postoperative complications (5.71% vs 5.71%, P=1.0), reoperations (5.71% vs 11.4%, P=.669), leg length discrepancy (5.33 vs 7.38 mm, P=.210), subsidence (20.0% vs 23.3%, P=.981), and Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement (78.6 vs 81.9, P=.723). We report comparable outcomes of conversion hip arthroplasty with the use of primary cementless and revision stems. Current primary cementless femoral stems may be considered for conversion hip arthroplasty for failed intertrochanteric fracture fixation. [Orthopedics. 2024;47(1):e6-e12.].

Abstract
The combination of an aging population and increased utilization of total hip arthroplasty (THA) is leading to a higher incidence of conversion THA, defined as conversion from previous hip fracture surgery to THA. Conversion THA is a more technically challenging, time-consuming, and costly procedure compared to primary THA and frequently involve more medically complex patients. Thus, the aim of this review is to provide a rubric for surgeons to use when preparing for a conversion THA. We have assessed the compatibility of commonly available extraction devices with popular femoral nails. Furthermore, we review technical pearls for conversion THA including equipment planning, operative setup, intraoperative imaging, extraction sequencing, and troubleshooting commonly encountered obstacles.

Abstract
BACKGROUND Ipsilateral femoral neck and hip fractures are uncommon high energy injuries. In the literature no single method of treatment has emerged as superior to the others. A recent publication has documented the successful application of the rendezvous technique using dual-implants for treating these injuries. However in some cases, this technique may fail and revision surgery is required. CASE PRESENTATION A 67-year old man sustained ipsilateral fractures of his femur and femoral neck in a road traffic accident. His injuries were treated by a dual construct consisting of a retrograde femoral nail and dynamic hip screw. Three months after surgery the hip screw cut out of the femoral head necessitating revision to a total hip arthroplasty. Surgery was carried out using a single stage two part procedure on a standard operating table without having to reposition or redrape the patient. There were no postoperative complications and at 1 year from surgery the patient is satisfied with the result and has returned to work. CONCLUSION Conversion hip arthroplasty in the presence of dual implants is a technically challenging and unpredictable procedure, with an increased risk of complications. Our surgical approach provides a framework for orthopedic surgeons to safely perform this complex procedure.

Abstract
BACKGROUND The incidence of conversion total hip arthroplasty (cTHA) following reduction and fixation for proximal femur fractures will increase in parallel to the aging population worldwide. OBJECTIVE The goal of this study is to report the frequency of bacterial detection and the outcome of cTHA at the authors' institution and to analyze preoperative factors that correlate with higher rates of bacterial growth and septic revision. METHODS 48 patients who had been converted to THA after osteosynthesis of a proximal femur fracture either by a one- or two-stage procedure were included. Septic failure rate and the frequency of bacterial detection at the time of fixation device removal were calculated. The influence of different preoperative factors was examined by the odds ratio. A receiver operating characteristic curve of c-reactive protein (CRP) for detection of bacterial growth at the time of fixation device removal was calculated. RESULTS 18.8% patients showed positive bacterial cultures, with Staph. epidermidis being the most frequent pathogen (33.3%). Septic failure after cTHA occurred in 4.2%. Fixation with cephalomedullary nails and complications with the internal fixation showed higher odds for bacterial growth at time of cTHA. CRP for predicting bacterial growth had an area under the curve of 0.661. Implant survival was worse when temporary spacers were used. CONCLUSION Bacterial detection rate at the time of cTHA is high, whereas septic failure rates are low. Isolated evaluation of inflammatory blood markers without other diagnostic modalities for infection is not decisive and does not justify a two-stage approach with implantation of a temporary spacer.

Abstract
BACKGROUND Conversion hip arthroplasty is defined as a patient who has had prior open or arthroscopic hip surgery with or without retained hardware that is removed and replaced with arthroplasty components. Currently, it is classified under the same diagnosis-related group as primary total hip arthroplasty (THA); however, it frequently requires a higher cost of care. METHODS A retrospective study of 228 conversion THA procedures in an orthopaedic specialty hospital was performed. Propensity score matching was used to compare the study group to a cohort of 510 primary THA patients by age, body mass index, sex, and American Society of Anesthesiologists score. These matched groups were compared based on total costs, implants used, operative times, length of stay (LOS), readmissions, and complications. RESULTS Conversion THA incurred 25% more mean total costs compared to primary THA (P < .05), longer lengths of surgery (154 versus 122 minutes), and hospital LOS (2.1 versus 1.56 days). A subgroup analysis showed a 57% increased cost for cephalomedullary nail conversion, 34% increased cost for sliding hip screw, 33% for acetabular open reduction and internal fixation conversion, and 10% increased costs in closed reduction and percutaneous pinning conversions (all P < .05). There were 5 intraoperative complications in the conversion group versus none in the primary THA group (P < .01), with no statistically significant difference in readmissions. CONCLUSION Conversion THA is significantly more costly than primary THA and has longer surgical times and greater LOS. Specifically, conversion THA with retained implants had the greatest impact on cost.

Abstract
OBJECTIVE Conversion total hip arthroplasty (CTHA) through a direct anterior approach (DAA) in supine position. INDICATIONS Failed osteosynthesis of proximal femoral fractures or failed conservative hip surgery, with hardware in situ. CONTRAINDICATIONS Decayed general conditions, infection (peri-implant or systemic infection), need for greater trochanter reconstruction, severe proximal femur deformity. SURGICAL TECHNIQUE Supine position. Mark DAA and expected limited incisions for hardware removal (HR) with the help of a C-arm. Use guidewire and extraction devices for HR. Perform a DAA with particular attention to a wide release of the femur. POSTOPERATIVE MANAGEMENT Full progressive weight-bearing starting on day 1, depending on bone quality. Discharge with crutches following patient walking capability. Precautions for 6 weeks. RESULTS In all, 27 conversion THAs through a DAA. Mean age at the time of surgery 59.8 (range 18-81) years. Mean body mass index was 23.5 (range 17-31.6). Reasons of previous surgery failures were avascular necrosis of the femoral head, posttraumatic arthritis and nonunion with or without hardware migration. Mean surgical time was 125.8 min (range 58-190 min, standard deviation [SD] 38.2 min). Mean follow-up time was 6.9 years (range 2-15, SD 5.03 years). Mean pre-Harris Hip Score (mHHs) was 24.4 (range 19-36, SD 5.4), while the mean post-mHHS was 90.3 (range 89-91, SD 0.95). Two patients required postoperative osteosynthesis for periprosthetic fractures due to falls. Overall complication rate was 10%.

How Does Conversion Total Hip Arthroplasty Compare to Primary? J Arthroplasty 2021; 36:S155-S159. [PMID: 33422393 DOI: 10.1016/j.arth.2020.12.023] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 12/08/2020] [Accepted: 12/15/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Recent institutional evidence suggests that conversion total hip arthroplasty (THA) incurs higher complication rates and costs when compared to primary THA. These findings contrast with the current reimbursement system as conversion and primary THAs are classified under the same diagnosis-related group. Thus, a national all-payer database was utilized to compare complication rates up to 2 years, 30-day readmission rates, and 90-day costs between conversion THA and matched primary THA patients. METHODS A retrospective review of the PearlDiver database between 2010 and second quarter of 2018 was performed using Current Procedural Terminology (CPT) codes to compare conversion THA (CPT 27132) to primary THA (CPT 27130). Patients were matched at a 1:3 ratio based on age, gender, Charlson Comorbidity Index, body mass index, tobacco use, and diabetes (conversion = 8369; primary = 25,081 patients). RESULTS Conversion THA had higher rates of periprosthetic joint infections (conversion: 7.7% vs primary: 1.4%), hip dislocations (4.5% vs 2.0%), blood transfusions (2.0% vs 1.0%), mechanical complications (5.5% vs 1.0%), and revision surgeries (4.0% vs 1.5%) (P < .001 for all) by 90 days. The 30-day readmission rate for conversion THA was significantly higher compared to the primary group (7.3% vs 3.3%) (P < .001). Median cost at 90 days for conversion THA was significantly higher compared to primary THA ($18,800 vs $13,611, P < .001). CONCLUSION This study revealed increased complication rates, revisions, readmissions, and costs among conversion THA patients compared to matched primary THA patients. These results support the reclassification of conversion into a diagnosis-related group separate from primary THA.

Abstract
AIMS Previous studies have already shown early proximal ingrowth, fast osseous integration, and a stable fit of the uncemented Symax hip stem, with excellent clinical and radiographic performance. Aims were to evaluate cumulative revision rates and reasons for revision of the Symax hip stem using Dutch Arthroplasty Register (LROI) data and to assess possible associations between patient characteristics and revision rate of the Symax hip stem. PATIENTS AND METHODS All total hip arthroplasties with the uncemented Symax hip stem registered in the LROI between 2007 and 2017 were included (n = 5,013). Kaplan-Meier survival analysis was performed to assess the cumulative 1, 5 and 7-year revision percentages. Cox proportional hazard regression analysis was performed to assess the association between patient and procedural characteristics, and revision arthroplasty of the stem. RESULTS Cumulative 1, 5, and 7-year revision rates (with 95% confidence interval (CI)) for revision of any component were 1.5% (CI 1.2%-1.8%), 3.2% (CI 2.7%-3.7%), and 3.8% (CI 3.1%-4.4%) respectively. Cumulative 1, 5, and 7-year stem revision rates of the Symax hip stem were 0.9% (CI 0.6%-1.1%), 1.5% (CI 1.1%-1.9%), and 1.7% (CI 1.3%-2.1%) respectively. Periprosthetic fractures (n = 35) and loosening of the stem (n = 30) were the most common reasons for revision of the stem. Revision of the stem was associated with acute fracture as primary diagnosis (Hazard Ratio (HR) 2.4 (CI 1.3-4.3)), or history of a previous surgery to the affected hip (HR 2.7 (CI 1.4-5.2)). CONCLUSION This population-based registry study shows revision rates for the Symax hip stem comparable to those for best performing uncemented total hip arthroplasties in the Netherlands. Primary diagnosis of an acute fracture, and history of previous surgery on the affected hip, were significantly associated risk factors for revision of the Symax hip stem, and we discourage the use of the Symax hip stem in these patients.

Does using different entrance points for intramedullary nails affect clinical outcomes for femoral shaft fractures? A retrospective clinical comparative study. North Clin Istanb 2021; 7:609-618. [PMID: 33381702 PMCID: PMC7754867 DOI: 10.14744/nci.2020.08058] [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: 04/10/2020] [Accepted: 05/29/2020] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVE We examined the clinical and radiological outcomes of femoral shaft fractures treated with two different intramedullary nail designs using either greater trochanteric or trochanteric fossa entrance. METHODS The medical records of patients undergoing operations for a shaft fracture either with a nail with trochanteric entrance or trochanteric fossa entrance were retrospectively reviewed. Inclusion criteria were: having the necessary medical records including radiographic images and follow-up data, at least 12 months of follow-up, skeletal maturity (≥16 years of age) not having osteoporosis (≤60 years of age). Exclusion criteria were: pathological fractures, fragility fractures, fractures that extend to hip or knee joint capsule, lack of enough medical data, less than 12 months of follow up, and patients yet to reach skeletal maturity. RESULTS A total of 65 patients (67 femur fractures) were treated with intramedullary nails using a trochanteric fossa entrance (TFE) and 21 patients (23 femur fractures) were treated with nails using a greater trochanteric entrance (GTE). No statistically significant differences were evident between groups in terms of union time, blood loss, need for implant removal, implant failure, or revision operation. However, the duration of postoperative hospitalization was significantly shorter in the GTE nail group and the need for open reduction of the fracture was less common in these patients. Although there were no significant differences between groups in terms of complications and union among isthmal and infra-isthmal fractures, malreduction and iatrogenic fractures were more common with the use of GTE nails for treatment of supra-isthmal fractures. CONCLUSION Use of intramedullary nails via both GTE and TFE were safe and efficient for the treatment of isthmal and infra-isthmal fractures. However, varus malalignments associated with iatrogenic fractures were more common with trochanteric entrance nails. Together, our results show that the use of nails via TFE may represent a safer option for surgical treatment of supra-isthmal fractures.

Abstract
Failed treatment of intertrochanteric (IT) femoral fractures leads to remarkable disability and pain, and revision surgery is frequently accompanied by higher complication and reoperation rates than primary internal fixation or primary hip arthroplasty. There is an urgent need to establish a profound strategy for the effective surgical management of these fragile patients. Salvage options are determined according to patient physiological age, functional level, life expectancy, nonunion anatomical site, fracture pattern, remaining bone quality, bone stock, and hip joint competency. In physiologically young patients, care should be taken to preserve the vitality of the femoral head with salvage internal fixation; however, for the elderly population, conversion arthroplasty can result in early weight bearing and ambulation and eliminates the risks of delayed fracture healing. Technical challenges include a difficult surgical exposure, removal of broken implants, deformity correction, critical bone defects, poor bone quality, high perioperative fracture risk, and prolonged immobilization. Overall, the salvage of failed internal fixations of IT fractures with properly selected implants and profound techniques can lead to the formulation of valuable surgical strategies and provide patients with satisfactory clinical outcomes.

Abstract
Conversion of prior proximal femoral fracture fixation to hip arthroplasty is a fairly common and successful procedure, necessitated by various modes of failure. The procedure is well described utilizing a posterior or anterolateral surgical approach. The anterior approach for total hip arthroplasty has gained in popularity. The approach allows for supine positioning and facilitates live fluoroscopic imaging. We present possible advantages and disadvantages, as well as the surgical technique, of conversion to total hip arthroplasty via the direct anterior approach.

Abstract
AIMS Cephalomedullary nails (CMNs) are commonly used for the treatment of intertrochanteric hip fractures. Total hip arthroplasty (THA) may be used as a salvage procedure when fixation fails in these patients. The aim of this study was to analyze the complications of THA following failed intertrochanteric hip fracture fixation using a CMN. PATIENTS AND METHODS Patients who underwent THA were identified from the 5% subset of Medicare Parts A/B between 2002 and 2015. A subgroup involving those with an intertrochanteric fracture that was treated using a CMN during the previous five years was identified and compared with the remaining patients who underwent THA. The length of stay (LOS) was compared using both univariate and multivariate analysis. The incidence of infection, dislocation, revision, and re-admission was compared between the two groups, using multivariate analysis adjusted for demographic, hospital, and clinical factors. RESULTS The Medicare data yielded 56 522 patients who underwent primary THA, of whom 369 had previously been treated with a CMN. The percentage of THAs that were undertaken between 2002 and 2005 in patients who had previously been treated with a CMN (0.346%) more than doubled between 2012 and 2015 (0.781%). The CMN group tended to be older and female, and to have a higher Charlson Comorbidity Index and lower socioeconomic status. The mean LOS was 1.5 days longer (5.3 vs 3.8) in the CMN group (p < 0.0001). The incidence of complications was significantly higher in the CMN group compared with the non-CMN group: infection (6.2% vs 2.6%), dislocation (8.1% vs 4.5%), revision (8.4% vs 4.3%), revision for infection (1.1% vs 0.37%), and revision for dislocation (2.2% vs 0.6%). CONCLUSION The incidence of conversion to THA following failed intertrochanteric hip fracture fixation using a CMN continues to increase. This occurs in elderly patients with increased comorbidities. There is a significantly increased risk of infection, dislocation, and LOS in these patients. Patients with failed intertrochanteric hip fracture fixation using a CMN who require THA should be made aware of the increased risk of complications, and steps need to be taken to reduce this risk.

Abstract
Posttraumatic arthritis accounts for a notable share of secondary osteoarthritis about the hip joint. Compared with total hip arthroplasty for primary osteoarthritis or inflammatory arthritis, total hip arthroplasty for posttraumatic arthritis offers greater technical challenges because of bone deformities and retained implants. Careful preoperative evaluation is necessary to prepare the approach, hardware removal strategy, and implants necessary to address bone deficiencies. Although arthroplasty is a highly successful procedure for posttraumatic arthritis, the results are less favorable than surgery for primary osteoarthritis. It is associated with a higher incidence of intraoperative and postoperative complications, including periprosthetic fractures, infection, instability, and decreased survivorship.

Abstract
BACKGROUND The aim of this study was to investigate the postoperative outcomes of cementless Total hip arthroplasty (THA) following failed internal fixation for femoral neck and intertrochanteric fractures. METHOD Ninety-six cementless THAs for failed internal fixation after femoral neck fracture (59, group I) and intertrochanteric fracture (37, group II) with a minimum follow-up of 3 years were analyzed. Clinical and radiologic evaluations were performed on all patients. RESULTS The intraoperative blood loss and operating time were significantly increased in group II (p = 0.001, p = 0.001, respectively). Harris hip score at last follow-up was significantly improved in group I (p = 0.007) but, there were no differences in hospital stay, Koval score at last follow-up, and perioperative complications between both groups. Long femoral stems for diaphyseal fitting were frequently used in group II (32/37, 86%) (p = 0.001). Radiographically, none of the acetabular cups showed evidence of migration, loosening. All cases showed stable fixation of the femoral stem at last follow-up. CONCLUSIONS Outcomes of cementless THA following failed internal fixation for femoral neck and intertrochanteric fractures were satisfactory; increased intraoperative blood loss, operating time, and requirement of long femoral stem should be considered in the latter type of fracture.

Orthop Traumatol Surg Res 2018; 104:681-686.

Abstract
INTRODUCTION The indications for total hip arthroplasty (THA) after failed internal fixation of a proximal femur fracture vary. Published studies on this topic are broad-ranging and do not distinguish between intracapsular and extracapsular fractures. This led us to conduct a retrospective analysis comparing the clinical outcomes, radiological outcomes, technical problems and complications between these two types of fractures. HYPOTHESIS The functional outcomes of THA after an extracapsular fracture will be worse than the ones after an intracapsular fracture. MATERIAL AND METHODS This was a retrospective, single-center study of 59 THA cases performed after internal fixation of a proximal femur fracture. These procedures were performed between 2002 and 2013 in 58 patients (22 men, 36 women). There were 40 intracapsular fractures and 19 extracapsular fractures. The initial fracture fixation involved a screw-plate (n=50), intramedullary nail (n=6) or screws (n=3). The mean patient age at the time of THA was 67 years [22-94]. The THA was performed an average of 2.8 years [0.2-28] after the fracture. The posterolateral approach was used in 55 cases (93%). Ten patients (17%) had the fixation hardware removed before the THA procedure, on average at 30 months [1-240] after the fracture. During the THA procedure, a cemented stem was used in 31 cases (53%) and a cementless stem in 28 cases (47%). A cementless press-fit cup was used in 56 cases (95%), of which 35 were dual mobility cups (60%), and a cemented cup was used in the other 3 cases (5%). All patients were reviewed by a physician not involved in the surgical procedures who performed a clinical and radiological examination. RESULTS No patients were lost to follow-up; two patients died. Ten patients suffered an intraoperative femur fracture (17%) and four suffered a dislocation (2 early, 2 late) (6.8%). Nine hips had to be reoperated (15%), of which five required an implant change (8.5%). There were significantly more intraoperative fractures and postoperative complications in the THA cases after extracapsular fracture. With a mean follow-up of 38 months [12-149], the mean PMA and Harris scores were 14.6 [3-18] and 74 [10-100], respectively; these scores were significantly lower in the THA cases after extracapsular fracture (p<0.05). With an endpoint of revision with implant change, the overall 40-month survival was 94% (95% CI: 0.25-0.55); it was 97% (95% CI: 0.62-0.85) for the intracapsular fracture cases and 84% (95% CI: 0.39-0.75) for the extracapsular fracture cases (p<0.05). CONCLUSION Secondary THA after failed fixation of proximal femur fractures has more complications than primary THA. Subgroup analysis identified more technical problems in the THA cases after extracapsular fracture and a higher number of complications, particularly dislocation and periprosthetic fractures. LEVEL OF EVIDENCE IV - Retrospective study.

Abstract
BACKGROUND With the increasing incidence of hip fractures and hip preservation surgeries, there has been a concomitant rise in the number of conversion total hip arthroplasties (THAs) performed. Prior studies have shown higher complication rates in conversion THA. However, there is a paucity of data showing differences in cost between these 2 procedures. Currently, the Center for Medicare and Medicaid Services bundles primary and conversion THA in the same Medicare Severity-Diagnosis Related Group for hospital reimbursement. More evidence is needed to support the reclassification of conversion THA. METHODS The cohort provided by the institutional database included 163 conversion THAs between January 1, 2012 and December 31, 2015. Intraoperative complications, estimated blood loss, operative time, postoperative complications, and perioperative cost data were analyzed for 163 primary THA patients matched to the conversion THA cohort. RESULTS Compared with primary THA, conversion THA had significantly (P < .05) greater cost for direct labor, other direct costs, intermediate nursing services, other diagnostic/therapy, surgery services, physical/occupational/speech therapy, radiology, laboratories, blood, medical/surgical supply, and total direct costs. In addition, the conversion THA group had significantly greater operative times, estimated blood loss, length of stay, intraoperative complications, and postoperative complications. CONCLUSION Conversion THA, as compared with primary THA, is associated with greater costs (approximately 19% greater), increased surgical times, and perioperative complications. To prevent these additional expenses from creating patient selection bias and a barrier to care, the conversion THA Medicare Severity-Diagnosis Related Group should be reclassified, or modifiers created.

Abstract
INTRODUCTION This study evaluated the effectiveness of hip resurfacing in patients with femoral deformities or retained femoral implants. Implant removal and conversion total hip replacement (CTHR) have been associated with increased operative time, blood loss, and cost. Removing intramedullary nails in particular can be difficult and can result in a more difficult recovery and/or complications. Hip resurfacing can be performed with a blocked femoral canal and has the possible additional benefits of a less-complex procedure, improved functional outcomes, better patient survivorship, and a possibly less-complicated revision should a failure occur. MATERIALS AND METHODS The author performed hip resurfacing in 61 patients (65 hips) with a blocked femur who had been advised elsewhere that they could not undergo THR without also undergoing additional surgical procedures. The perioperative complexity of resurfacing was evaluated by recording operative time, blood loss and functional outcomes using the Harris Hip Score (HHS) and Short-Form 12 (SF-12) questionnaire. Implant survivorship was evaluated by the need for revision surgery. RESULTS At 9 years' mean follow-up (range 5-19 years), 59 of the 61 patients presented for postoperative evaluation. The mean operative time was 104 minutes and the mean blood loss was 300 cc. The mean HHS improved from 41 to 92 ( p < 0.001) and the mean SF-12 physical and mental scores improved from 26 to 49 and from 44 to 54, respectively ( p < 0.001). None of the procedures failed or required revision. CONCLUSION Canal-sparing hip resurfacing is a successful and less complicated option than CTHR when there is deformity or retained implant blocking the femoral canal.

Hip Arthroplasty After Surgical Treatment of Intertrochanteric Hip Fractures. J Arthroplasty 2017; 32:3438-3444.

Abstract
BACKGROUND Although use of intramedullary hip screws (IMHS) for intertrochanteric (IT) hip fractures has become more common, limited data have suggested difficulties in conversion to hip arthroplasty. The present study investigates whether conversion of failed IT fracture fixation with an intramedullary vs extramedullary device leads to different rates or types of complications or decreased arthroplasty survivorship. METHODS One hundred eleven patients were converted to hip arthroplasty after previous surgical treatment of an IT fracture from 2000 to 2010. Seventy hips had been treated with an extramedullary fixation device (EFD) and 41 with an IMHS. RESULTS Length of hospital stay and operative times were similar (6 days and 206 minutes for EFD vs 6 days and 208 minutes for IMHS; P > .7). The presence of a Trendelenburg gait at last clinical follow-up was similar between groups (37% in EFD group and 38% in IMHS group). Five-year survivorship free of revision was 95% in the EFD group and 94% in the IMHS group (P = 1.0). The overall complication rate was similar (21% for EFD vs 27% for IMHS; P = .51) between groups. The most common complication was late periprosthetic fracture in the EFD patients (6% vs 0% in IMHS; P = .29) and intraoperative femoral fracture in the IMHS patients (12% vs 1% in EFD; P = .02). CONCLUSION The short-term survivorship of conversion hip arthroplasty after surgical treatment of an IT fracture is excellent regardless of original fracture fixation method. If early complications, particularly periprosthetic fractures, can be minimized, the likelihood of a successful outcome is high. The risk of intraoperative femoral fracture was greater during conversion from an IMHS compared to an EFD.

Abstract
BACKGROUND The incidence of hip fractures is growing with the increasing elderly population. Typically, hip fractures are treated with open reduction internal fixation, hemiarthroplasty, or total hip arthroplasty (THA). Failed hip fracture fixation is often salvaged by conversion THA. The total number of conversion THA procedures is also supplemented by its use in treating different failed surgical hip treatments such as acetabular fracture fixation, Perthes disease, slipped capital femoral epiphysis, and developmental dysplasia of the hip. As the incidence of conversion THA rises, it is important to understand the perioperative characteristics of conversion THA. Some studies have demonstrated higher complication rates in conversion THAs than primary THAs, but research distinguishing the 2 groups is still limited. METHODS Perioperative data for 119 conversion THAs and 251 primary THAs were collected at 2 centers. Multivariable linear regression was performed for continuous variables, multivariable logistic regression for dichotomous variables, and chi-square test for categorical variables. RESULTS Outcomes for conversion THAs were significantly different (P < .05) compared to primary THA and had longer hospital length of stay (average 3.8 days for conversion THA, average 2.8 days for primary THA), longer operative time (168 minutes conversion THA, 129 minutes primary THA), greater likelihood of requiring metaphysis/diaphysis fixation, and greater likelihood of requiring revision type implant components. CONCLUSION Our findings suggest that conversion THAs require more resources than primary THAs, as well as advanced revision type components. Based on these findings, conversion THAs should be reclassified to reflect the greater burden borne by treatment centers.

BMC Musculoskelet Disord 2017; 18:38. [PMID: 28122548 PMCID: PMC5264307 DOI: 10.1186/s12891-017-1415-6] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2016] [Accepted: 01/18/2017] [Indexed: 01/08/2023] Open
Abstract
Background Conversion to total hip arthroplasty (CTHA) is a relatively common procedure after a failed dynamic hip screw (DHS) or proximal femoral nail anti-rotation (PFNA) fixation of intertrochanteric fractures, but there have been far fewer reports specifically describing the long-term results of CTHA after failed treatments of stable intertrochanteric fractures with DHS or PFNA. The aim of the present study was to compare the clinical and radiological outcomes of CTHA after failed PFNA or DHS fixations of stable intertrochanteric fractures after a minimum follow-up of 3 years. Methods Between January 2005 and April 2014, we retrospectively reviewed 142 active elderly patients treated at our institution (a single institution study). A total of 72 patients (72 hips; 41 women, 31 men; mean age 76.9 years old; range 60–92 years old) who underwent conversion of a failed PFNA to a THA were compared with 70 patients (70 hips; 36 women, 34 men; mean age 75.0 years old; range 60–90 years old) who underwent CTHA after a failed DHS fixation. The mean follow-up periods were 48 (range 43–52) and 48 (range 44–52) months for the DHS and PFNA groups, respectively. Clinical and radiologic evaluations were performed on all patients. The primary outcome was the Harris Hip Score (HHS). The secondary outcomes were the complication rates. Results The Harris Hip Score (HHS) improved from 50.61 ± 3.23 preoperatively to 85.28 ± 4.45 at the last follow-up in the PFNA group and from 51.46 ± 3.90 to 84.50 ± 4.34 in the DHS group, with no significant differences noted between the groups at each follow-up (P > 0.05). However, the complication rate in the converted DHS patients was significantly higher (42.9%) than that in the converted PFNA patients (20.8%; P = 0.003). Thirty-seven PFFs (2.4%) occurred during a mean follow-up of 44.4 months. The incidence of periprosthetic fractures was found to be significantly higher (P = 0.021) for the DHS group (15.7%) than for the PFNA group (4.2%). Conclusions CTHA after failed DHS fixations of stable intertrochanteric fractures might be associated with a significantly higher complication rate than CTHA after failed PFNA fixations. Therefore, PFNA patients with stable intertrochanteric fractures may be more suitable for CTHA.

Abstract
The optimal entry point for antegrade intramedullary nailing of femoral shaft fractures remains controversial. The purpose of this systematic review was to determine whether there is a difference in operative parameters, healing, and functional outcome when comparing the greater trochanter (GT) and piriformis fossa (PF) entry points. A systematic search of multiple databases and 3 major orthopedic meetings (American Academy of Orthopaedic Surgeons, Canadian Orthopaedic Association, and Orthopaedic Trauma Association) was conducted. Four studies (570 patients) met the inclusion criteria. Mean patient age was 34.5 years, and 60.4% were male. The GT entry point was associated with significantly shorter operative (mean difference [MD], -20.05 minutes [95% confidence interval (CI), -23.09 to -17.02]; P<.00001) and fluoroscopy times (MD, -24.55 seconds [95% CI, -43.23 to -5.86]; P=.01). There was no significant difference in nonunion (risk ratio [RR], 0.74 [95% CI, 0.35 to 1.58]; P=.44) and delayed union rates (RR, 0.94 [95% CI, 0.41 to 2.14]; P=.88) between the 2 entry points. Heterogeneity in outcome measures reported prevented pooled analysis of functional outcomes. This review supports the use of the GT entry point during antegrade nailing of femoral shaft fractures over the PF entry point, with regard to shorter operative and fluoroscopy times. Healing and complication rates were not related to the entry point. Further study is required to determine the effect of each entry point on the surrounding soft tissue structures and ultimately its impact on postoperative function.

Abstract
Purpose People with dementia have poor mobility and discharge outcomes following hip fractures. The purpose of this study was to evaluate the clinical and radiological results of internal fixation of undisplaced femur neck fractures (Garden types 1 and 2) by proximal femoral nail antirotation (PFNA) in dementia patients. Materials and Methods We studied retrospectively 19 patients with undisplaced femur neck fracture. All patients were over 70 years of age, walked independently with a cane or crutches and suffered moderate-to-severe dementia. Patients were treated with PFNA and followed-up for more than 2 years. Revision, loss of fixation, complications, and walking ability outcomes were measured. Results In walking-ability evaluation, patients showed an average decrease of just 0.2 points at the final follow-up. Walking ability was evaluated from before injury to 4 weeks after surgery and decreased by less than 0.5 points. Radiological bone union was achieved in 17 cases; the average time to bone union was 4.14 months (range, 2.5-7 months). Complications included non-union in two cases and femoral head avascular necrosis in one case of non-union. Conclusion We found that for patients with osteoporotic bone tissues in their femoral heads or patients (e.g., those suffering dementia) for whom cooperating with medical workers for postoperative walking control or rehabilitation exercises is difficult, implanting a mechanically stable spiral blade for fixation of femoral neck fractures could facilitate walking after surgery.

Abstract
Total hip arthroplasty can be a very effective salvage treatment for both failed fracture surgery and hip arthritis that may occur after prior fracture surgery. The rate of complications is significantly increased including especially infection, dislocation, and loosening. Complications are more likely to occur after failed open reduction and internal fixation than after posttraumatic arthritis. Adequately ruling out infection before hip arthroplasty can be difficult. The best predictor of infection is a prior infection. Long-term outcomes can be comparable to outcomes in other conditions if complications are avoided.

Abstract
Purpose This study was aimed to explore and report the short term results of primary cementless hip arthroplasty in treatment of unstable intertrochanteric femur fracture in elderlys. Materials and Methods Between March 2009 and Feburary 2012, 35 arthroplasty cases performed by single surgeon and followed up for more than one year were evaluated. They were 21 females and 14 males with mean age of 78 years (range, 71-92 years). Preoperative evaluation was performed by American Society of Anesthesia score. Retrospective evaluation was performed by operative time, transfusion amount, time to operation days, hospital stay and time to full weight bearing. Clinically, ambulatory ability was checked by Parker and Palmer (P&P) score and function of hip was appraised by Harris hip score (HSS). Radiologically, bone healing of fractured trochanteric fragment and presence of subsidence, stress shielding or osteolysis were checked. Results Fracture type was 11 cases of A2.2, 18 cases of A2.3 and 6 cases of A3.3. Femoral stems used were 8 cases of rectangular tapered wedge type and 27 cases of fluted modular distal fixation type. P&P score improved from mean preinjury score of 7.1 to mean postoperative last follow-up score of 6.5. Median HHS at last follow-up was 75. Mean time to full weight bearing was 47 days (24-79 days). Postoperative complications were one case of linear periprosthetic femoral fracture and one case of postoperative dislocation. Conclusion Cementless hip replacement arthroplasty could be a good option for unstable intertrochanteric femoral fracture in elderlys.

Increased complication rate following conversion total hip arthroplasty after cephalomedullary fixation for intertrochanteric hip fractures: a multi-center study. J Arthroplasty 2013; 28:45-7. [PMID: 23891060 DOI: 10.1016/j.arth.2013.04.048] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2012] [Revised: 03/07/2013] [Accepted: 04/07/2013] [Indexed: 02/01/2023] Open
Abstract
Cephalomedullary devices (CMN) have become an increasingly popular for treatment of intertrochanteric hip fractures compared to sliding hip screw and side plate (SHS) devices. Failed fixation is often treated with conversion total hip arthroplasty (THA). We performed a multi-institutional study in which 60 patients with SHS devices and 31 patients with CMN devices were converted to THA. Harris Hip Score improved from 41.6 preoperatively to 83.6 at final follow-up in the SHS group and from 41.6 to 78.6 in the CMN group, with no significant difference between the groups (P=0.23). However, the complication rate in converted CMN patients was significantly higher at 41.9% compared with 11.7% (P=0.001) in converted SHS patients. Prior fixation with CMN may be associated with significantly higher complication rates during conversion.

Salvage hip arthroplasty after failed fixation of proximal femur fractures. J Arthroplasty 2013; 28:855-9. [PMID: 23489728 DOI: 10.1016/j.arth.2012.10.027] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2012] [Revised: 10/16/2012] [Accepted: 10/28/2012] [Indexed: 02/01/2023] Open
Abstract
We reviewed 46 patients who underwent salvage hip arthroplasty (SHA) for revision of failed cannulated screws (CS), sliding hip screws (SHS), or intramedullary nails (IMN). The primary objective was to determine differences in operative difficulty. SHA after failed femoral neck fixation was associated with lower intra-operative demands than after failed peri-trochanteric fractures. Similarly, analysis by the index implant found that conversion arthroplasty after failed CSs was associated with lower intra-operative morbidity than failed SHSs or IMNs; differences between SHS and IMN were not as clear. Importantly, intra-operative data in cases of failed SHSs were similar regardless of the original fracture type, showing the device played a larger role than the fracture pattern. Complications and revision surgery rates were similar regardless of fracture type or fixation device. Our results suggest that operative demands and subsequent patient morbidity are more dependent on the index device than the fracture pattern during SHA.
