Hip fracture types in men and women change differently with age

Robot-assisted versus traditional surgery in the treatment of intertrochanteric fractures: a meta-analysis

Intramedullary nail fixation of intertrochanteric fractures assisted by orthopedic surgical robot navigation is a new surgical method, but there are few studies comparing its efficacy with traditional intramedullary nail fixation. We aimed to assess whether robot-assisted internal fixation confers certain surgical advantages through a literature review. PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wan fang Data Knowledge service Platform were searched to collect randomized and non-randomized studies on patients with calcaneal fractures. Five studies were identified to compare the clinical indexes. For the clinical indexes, the technology of robot-assisted is generally feasible, in time to operation, intraoperative fluoroscopy times, blood loss, pine insertion, tip apex distance (TAD), and Harris score (P < 0.05). However, on the complication and excellent and good rate after operation did not show good efficacy compared with the traditional group (P > 0.05). Based on the current evidence, For the short-term clinical index, the advantages of robot-assisted are clear. The long-term clinical effects of the two methods are also good, but the robot-assisted shows better. However, the quality of some studies is low, and more high-quality randomized controlled trials (RCTs) are needed for further verification.

Outcomes of Name-brand Versus Generic Cephalomedullary Nail Fixation for Intertrochanteric and Subtrochanteric Fractures: A Matched Cohort Study

This study aims to compare 90-day and 6-month outcomes and implant costs of intertrochanteric and subtrochanteric fracture fixation using cephalomedullary nails (CMNs) from a single name-brand company to fixation using generic CMNs. This was a retrospective matched cohort study. All CMN procedures for a single surgeon in a single US metropolitan institution from 2021 to 2022 were identified using current procedural terminology codes. Nearest neighbor 1:1 matching was conducted between the name-brand and generic cohorts controlling for (1) age, (2) American Society of Anesthesiologists score, and (3) Charlson Comorbidity Index. A total of 50 patients were successfully matched (25 namebrand versus 25 generic). The average implant cost per case for the name-brand group was $3,587 versus $1,615 for the generic group. Cost of disposables averaged $109 for the generic implant sets versus $916 for the name-brand (P < 0.001). Overall, a cost savings of 61% could be generated per case with the use of generic implants and disposables. Fixation of intertrochanteric and subtrochanteric fractures using generic CMNs produces similar outcomes compared with using name-brand CMNs for approximately half the implant cost.

Intertrochanteric Femoral Fractures: A Comparative Analysis of Clinical and Radiographic Outcomes Between Talon Intramedullary Nail and Intertan Nail

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.

Pertrochanteric hip fracture is associated with mobility decline and poorer physical performance 4 to 6 months post-hip fracture

BACKGROUND

To study the effect of hip fracture type on physical performance, functional ability and change in mobility four to six months after the injury.

METHODS

A total of 1331 patients out of consecutive 2052 patients aged ≥ 65 years who underwent hip fracture surgery were included in the study. Patient information was collected on admission, during hospitalization, by phone interview and at the geriatric outpatient clinic 4 to 6 months after the fracture. Of the 1331 eligible patients, Grip strength, Timed Up and Go -test (TUG), Elderly Mobility Scale (EMS), mobility change compared to pre-fracture mobility level, Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) were used to determine physical performance and functional ability. Logistic regression was used for the analyses which was adjusted for gender, age, American Society of Anesthesiologists score, diagnosis of cognitive disorder, pre-fracture living arrangements, mobility and need of mobility aid.

RESULTS

Patients with pertrochanteric hip fracture had an EMS lower than 14 (Odds Ratio (OR) 1.38, 95% confidence intervals (CI) 1.00-1.90), TUG time ≥ 20 s (OR 1.69, 95% CI 1.22-2.33) and they had declined in mobility (OR 1.58, 95% CI 1.20-2.09) compared to femoral neck fracture patients 4 to 6 months post-hip fracture in multivariable-adjusted logistic regression analyses. Grip strength and functional ability (IADL, BADL) 4 to 6 months after hip fracture did not differ between fracture types. There were no statistically significant differences in physical performance in patients with a subtrochanteric fracture compared to patients with a femoral neck fracture.

CONCLUSIONS

Pertrochanteric hip fracture independently associated with poorer physical performance 4 to 6 months post hip fracture compared to other hip fracture types. Pertrochanteric hip fracture patients should be given special attention in terms of regaining their previous level of mobility.

Biomechanical evaluation of three implants for treating unstable femoral intertrochanteric fractures: finite element analysis in axial, bending and torsion loads

Purpose: How to effectively enhance the mechanical stability of intramedullary implants for unstable femoral intertrochanteric fractures (UFIFs) is challenging. The authors developed a new implant for managing such patients. Our aim was to enhance the whole mechanical stability of internal devices through increasing antirotation and medial support. We expected to reduce stress concentration in implants. Each implant was compared to proximal femoral nail antirotation (PFNA) via finite element method. Methods: Adult AO/OTA 31-A2.3 fracture models were constructed, and then the new intramedullary system (NIS), PFNA, InterTan nail models were assembled. We simulated three different kinds of load cases, including axial, bending, and torsion loads. For further comparison of PFNA and the NIS, finite element analysis (FEA) was repeated for five times under axial loads of 2100 N. Two types of displacement and stress distribution were assessed. Results: Findings showed that the NIS had the best mechanical stability under axial, bending, and torsion load conditions compared to PFNA and InterTan. It could be seen that the NIS displayed the best properties with respect to maximal displacement while PFNA showed the worst properties for the same parameter in axial loads of 2100 N. In terms of maximal stress, also the NIS exhibited the best properties while PFNA showed the worst properties in axial loads of 2100 N. For bending and torsion load cases, it displayed a similar trend with that of axial loads. Moreover, under axial loads of 2100 N, the difference between the PFNA group and the NIS group was statistically significant (p < 0.05). Conclusion: The new intramedullary system exhibited more uniform stress distribution and better biomechanical properties compared to the PFNA and InterTan. This might provide a new and efficacious device for managing unstable femoral intertrochanteric fractures.

A biomechanical investigation of a novel intramedullary nail used to salvage failed internal fixations in intertrochanteric fractures

PURPOSE

The ideal approach for revision surgery following femoral head salvage treatments for an intertrochanteric fracture is still up for debate. A novel variety of proximal femoral bionic intramedullary nail (PFBN) has been created in clinical practice. We aimed to compare the biomechanical results of the novel implant to conventional intramedullary and extramedullary fixation in the treatment of intertrochanteric fracture following primary internal fixation failure.

METHODS

Using finite element analysis, we created a three-dimensional model of the intertrochanteric fracture's helical blade cut-out for this investigation. The PFBN 1 group, the PFBN 2 group, the PFNA group, and the DHS group were our four test groups. For each fracture group, the von Mises stress and displacements of the femur and internal fixation components were measured under 2100 N axial loads.

RESULTS

The values for the femoral displacement in the PFBN1 group, PFBN2 group, PFNA group, and DHS group were 6.802 mm, 6.716 mm, 8.080 mm, and 8.679 mm, respectively. The internal implant displacement values were 6.201 mm, 6.138 mm, 7.396 mm, and 8.075 mm in the PFBN1 group, PFBN2 group, PFNA group, and DHS group, respectively. The maximum von Mises Stress in the femoral was 187.2 MPa, 85.18 MPa, 106.6 MPa, and 386.2 MPa in the PFBN1 groups, PFBN2 groups, PFNA groups, and DHS groups, respectively. In the PFBN1 groups, PFBN2 groups, PFNA groups, and DHS groups, the maximum von Mises Stress in internal fixation was 586.7 MPa, 559.8 MPa, 370.7 MPa, and 928.4.8 MPa, respectively.

CONCLUSION

Our biomechanical research demonstrates that intramedullary fixation is more stable than extramedullary fixation when salvaging failed internal fixations in intertrochanteric fracture. Compared with PFNA and DHS, PFBN showed better biomechanical stability in the treatment of patients with revised intertrochanteric fractures. In light of this, we advocate PFBN fixation as the method of choice for intertrochanteric fracture revision. This result still has to be confirmed in more clinical research.

Delayed surgery and health related quality of life in patients with proximal femoral fracture

This study aimed to establish factors associated with delayed surgery in patients with proximal femoral fracture and to assess patients' health-related quality of life (HRQoL) after surgery including all-cause 6-months mortality. This was a single-center, observational, prospective cohort study that included patients with a proximal femur fracture. We described patients' HRQoL measured by EuroQoL (EQ-5D-5L and EQ-VAS) questionnaire and perioperative complications (including mortality) 6 months after surgery. We included 163 patients with a mean age of 80.5 years, the majority were women and 76.1% reported falling from their own height. The mean time between hospital admission and surgery was 8.3 days (SD 4.9 days) and the mean hospital stay was 13.5 days (SD 10.4 days). After adjustment, the principal factor associated with delayed surgery was adjournment in surgery authorization (3.7 days). EQ-5D-5L index values and the VAS score at 1 month after surgery were 0.489 and 61.1, at 3 months were 0.613 and 65.8, and at 6 months 0.662 and 66.7 respectively. Mortality at 6 months of follow-up was 11% (18 patients). In conclusion, administrative authorization was the strongest associated factor with delayed time from hospital admission to surgery. HRQoL of patients with a proximal femoral fracture improved 6 months after surgery.Trial registration: NCT04217642.

Evolutionary roots of the risk of hip fracture in humans

The transition to bipedal locomotion was a fundamental milestone in human evolution. Consequently, the human skeleton underwent substantial morphological adaptations. These adaptations are responsible for many of today's common physical impairments, including hip fractures. This study aims to reveal the morphological changes in the proximal femur, which increase the risk of intracapsular hip fractures in present-day populations. Our sample includes chimpanzees, early hominins, early Homo Neanderthals, as well as prehistoric and recent humans. Using Geometric Morphometric methods, we demonstrate differences in the proximal femur shape between hominids and populations that practiced different lifestyles. We show that the proximal femur morphology is a risk factor for intracapsular hip fracture independent of osteoporosis. Changes in the proximal femur, such as the shortening of the femoral neck and an increased anterolateral expansion of the greater trochanter, are associated with an increased risk for intracapsular hip fractures. We conclude that intracapsular hip fractures are a trade-off for efficient bipedal walking in humans, and their risk is exacerbated by reduced physical activity.

Clinical and Demographic Characteristics of Centenarians versus Other Age Groups Over 75 Years with Hip Fractures

Objective

The primary objective was to describe the clinical characteristics, management, and outcomes of centenarians with fragility hip fracture and compare them to other age groups. The secondary objective was to determine the variables associated with length of stay, in-hospital mortality and 30-day mortality.

Materials and Methods

This is a secondary analysis of the Spanish National Hip Fracture Registry. We included patients ≥75 years admitted for fragility hip fractures in 86 Spanish hospitals between 2017 and 2019, dividing the sample into four age groups. The variables studied were baseline characteristics, type of fracture, management, length of stay, in-hospital mortality and 30-day mortality.

Results

We included 25,938 patients (2888 were 75-79 years old; 14,762 octogenarians; 8,035 nonagenarians and 253 centenarians). Of the centenarians, 83% were women, 33% had severe dementia, 9% had severe dependency and 36% lived in residential care homes. Six out of ten had intertrochanteric fracture. Length of hospital stay was 8.6 days; in-hospital mortality was 10.3% and 30-day mortality 20.9%. Older age groups had more women, severe functional dependency, severe dementia, intertrochanteric fracture, living in care facilities and being discharged to nursing care. They had less frequent early mobilization, osteoporosis treatment and discharge to rehabilitation units. In-hospital and 30-day mortality were higher with increasing age. In centenarians, time to surgery >48 hours was independently associated with length of stay (correlation coefficient 3.99 [95% CI: 2.35-5.64; p<0.001]) and anaesthetic risk, based on an ASA score of V, was related to 30-day mortality (ASA score II [OR 0.25, 95% CI: 0.09-0.70; p=0.009] and ASA score III [OR 0.43, 95% CI: 0.19-0.96; p=0.039]).

Conclusion

Centenarians had different clinical characteristics, management and outcomes. Although centenarians had worse outcomes, nearly 4 out of 5 centenarians were alive one month after surgery.

Hip structure analysis and femoral osteodensitometry in aged postmenopausal women with hip osteoarthritis and femoral neck fracture

PURPOSE

Osteoarthritis (OA), osteoporosis, and bone fractures are frequent aging-related conditions. Regardless of the growing research interest in the effects of hip OA on femoral fracture risk, data about the region specificity of osteodensitometric and hip structure analysis (HSA) parameters of the proximal femora are lacking in aged postmenopausal women with hip OA compared to individuals with femoral neck fragility fracture.

METHODS

This study included 76 postmenopausal women admitted for total hip arthroplasty due to non-traumatic femoral neck fracture (FN_Fx group, n = 39) and hip osteoarthritis (OA group, n = 37).

RESULTS

Osteodensitometric parameters differed significantly between the OA and FN_Fx groups, depicting lower bone mineral density in the FN_Fx group (p < 0.05). The most significant increase in these parameters was registered in the intertrochanteric region of the OA group. Moreover, the OA-induced changes in HSA-derived parameters displayed significant regional heterogeneity, with the intertrochanteric region showing the most notable difference between OA and FN_Fx group.

CONCLUSION

Our data may indicate that OA displayed the most prominent positive effect on the intertrochanteric femoral region, revealing the regional heterogeneity in structural geometry and biomechanical indices of proximal femora in OA individuals. Since we did not observe significant differences in the femoral neck region, we may speculate that OA does not have a substantial protective effect on the femoral neck fracture risk in aged postmenopausal women.

Risk factors for prolonged preoperative waiting time of intertrochanteric fracture patients undergoing operative treatment

Purpose

Intertrochanteric fracture is a common fracture in older adults. We observed the case characteristics of intertrochanteric fracture and analyzed the risk factors for prolonged preoperative waiting time based on patient data from a 6 year period. Investigate the post-admission treatment of intertrochanteric fracture.

Methods

We retrospectively reviewed the medical records from July 2015 to July 2021 of patients hospitalized for intertrochanteric fracture who had undergone internal fixation surgery in the orthopedic ward of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine. Data regarding gender, age, AO/OTA classification, preoperative waiting time, preoperative medical comorbidities, and complicated deep venous thrombosis (DVT) of lower limbs were collected. Statistical tests were used to evaluate the factors influencing preoperative preparation time and DVT.

Results

A total of 1812 cases were retrospectively analyzed, 1258 patients (69.43%) had three or more medical comorbidities. The average preoperative waiting time was 5.09 ± 3.27 days. Advanced age, more preoperative medical comorbidities and DVT led to longer preoperative waiting times, and preoperative medical comorbidities were an independent risk factor. Patients with advanced age and preoperative medical comorbidities were more likely to have DVT.

Conclusion

Age and preoperative medical comorbidities are risk factors for DVT and prolonged preoperative preparation time in intertrochanteric fracture patients. Preoperative medical comorbidities are an independent risk factors affecting the preoperative waiting time, and a combination of multiple comorbidities almost predicts the delay of the operation time.

Does anatomical type of proximal hip fracture affect rehabilitation outcomes among older adults?

BACKGROUND AND PURPOSE

Numerous studies have detailed the potential benefits of inpatient geriatric rehabilitation for older adults with hip fractures. However, data regarding effect of fracture type (femoral neck, intertrochanteric, or subtrochanteric) on rehabilitation outcomes are limited. This study assessed whether the anatomical type of proximal hip fracture affects rehabilitation outcomes among disabled older adults.

METHODS

A population-based study was conducted comparing all patients with a recent hip fracture who were admitted to a geriatric rehabilitation facility in Israel. Data were collected retrospectively from an electronic database during a 5-year period (2014-2019). The Functional Independence Measure (FIM) was used to assess physical and cognitive function at admission and discharge.

RESULTS

The analyses included 624 older adults with hip fractures. We found significant differences in motor FIM score at admission, as patients with femoral neck fracture performed better than patients with intertrochanteric and subtrochanteric fracture did. The disparity in motor FIM score remained consistent through discharge, with all groups achieving a median gain of 14 points. Within one month of rehabilitation, about a third of all patients achieved a higher functional level.

CONCLUSIONS

Patients with femoral neck fracture have better motor ability than do those with intertrochanteric and subtrochanteric fractures, which were retained throughout the course of rehabilitation; yet, the level of improvement remained similar. Clinicians should be aware of such differences in functional ability when discussing goals of care with older adults with hip fractures and consider them when implementing individual rehabilitation programs .

Adherence to Exercise Programs in Community-Dwelling Older Adults Postdischarge for Hip Fracture: A Systematic Review and Meta-analysis

OBJECTIVE

To determine whether older adults adhere to exercise programs after discharge for hip fracture and how adherence relates to exercise program characteristics and intervention efficacy.

DATA SOURCES

Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health, Embase, Physiotherapy Evidence Database, Web of Science, SPORTDiscus, PsycINFO, PubMed, and Ovid MEDLINE were searched from inception to August 2020.

STUDY SELECTION

Randomized controlled trials of exercise interventions in adults older than 60 years with a surgically managed hip fracture that provided a measure of adherence were selected by 2 independent reviewers.

DATA EXTRACTION

Data were extracted independently by 1 reviewer and cross-checked by a second reviewer for accuracy. Risk of bias was assessed with 2 tools: a customized checklist was used to examine sources of bias and ambiguity for adherence data, and the Cochrane Risk of Bias tool was used to assess the interval validity of studies.

DATA SYNTHESIS

Seventeen trials with 1850 participants (mean age, 78.8 years) were included in the review. The pooled estimate of adherence to exercise programs post hip fracture was 0.88 (95% CI, 0.78-0.95). Programs that were more than 6 months in duration were associated with a decrease in adherence (odds ratio, 0.29; 95% CI, 0.11-0.77). However, increased adherence was not associated with improvements in functional outcomes. None of the other program characteristics were associated with improvements in functional outcomes.

CONCLUSIONS

Adherence to exercise programs after hip fracture appears to be high and may be related to program duration. However, there is a need for a standardized approach to measure and report adherence data in future studies to determine whether exercise adherence is associated with improvements in function for this population.

Effect of Age on the Patterns of Traumatic Femoral Fractures: Seven Years of Experience at a Regional Tertiary Hospital

Objective

Femoral fractures are a common cause of mortality and functional loss, mainly among older people, and there are few studies about the age in relation to traumatic femoral fractures. The aim of this study was to investigate the effect of age on the patterns of traumatic femoral fractures in patients presenting to our regional tertiary hospital.

Methods

The records of 2020 patients who presented with traumatic femoral fractures between 2013 and 2019 were retrospectively reviewed. The patients' clinical and radiographic records were reviewed. Univariate and multivariable logistic regression were used to identify independent risk factors for associated injuries and complications.

Results

The patients were divided into a child group (CH group, n = 342) aged under 18 years, a young adult group (YA group, n = 484) aged 18–60 years, and an older people group (OP group, n = 1194) aged 60 years and over. There were significant differences among the three groups in several indexes, such as sex ratio (χ² = 301.699, p < 0.001), osteoporosis (χ² = 375.463, p < 0.001), injury time of day (χ² = 114.913, p < 0.001), injury cause (χ² = 748.187, p < 0.001), injury location (χ² = 490.153, p < 0.001), fracture side (χ² = 57.000, p < 0.001), fracture site (χ² = 806.650, p < 0.001), associated injuries (χ² = 322.921, p < 0.001), coma after injury (χ² = 147.814, p < 0.001), non‐surgery‐related complications (χ² = 7.895, p = 0.019), and surgery‐related complications (χ² = 82.186, p < 0.001). The YA group had a significantly higher percentage of patients with surgery‐related complications than the OP group. The OP group had a higher frequency of non‐surgery‐related complications than the YA group and CH group. The most common non‐surgery‐related complications were pneumonia (7.1%) in the OP group and deep venous thrombosis (6.4%) in the YA group. Multivariable logistic regression showed that young adults, high‐energy injury, outdoors, coma after injury, and fracture sites except for the proximal region were independent risk factors for associated injuries. Older age, male, and fracture site except for the proximal region were independent risk factors for complications.

Conclusions

Traumatic femoral fractures are mostly the result of low‐energy trauma and predominantly affect the proximal site of the femur among older people. A higher rate of shaft fractures, fractures occurring outdoors, and associated injuries were observed among young adults and children than among older people.

Finite Element Analysis of Proximal Femur Bionic Nail (PFBN) Compared with Proximal Femoral Nail Antirotation and InterTan in Treatment of Intertrochanteric Fractures

Objective

To compare the biomechanical properties of proximal femur bionic nail (PFBN), proximal femoral nail antirotation (PFNA) and InterTan in the treatment of elderly intertrochanteric fractures AO/OTA 31‐A1.3 by finite element analysis.

Methods

We used Mimics, Unigraphics and other software to establish normal femur and AO/OTA 31‐A1.3 fracture models, and reconstructed PFBN, PFNA and InterTan intramedullary nail models, and assembled them on the fracture model. The ANSYS software was used to compare the femoral von Mises stress distribution, deformation distribution, and internal fixation stress distribution of each group under a load of 2100 N.

Results

It could be seen that the femoral maximum stress, femoral maximum displacement, and maximum stress of internal fixation of the PFBN group were lower than those in the PFNA group and the InterTan group. The maximum femoral stress of the PFBN was 190.25 MPa, while the maximum stress of the femur of the PFNA and InterTan groups were 238.41 Mpa and 226.97 Mpa. The maximum femoral displacement of each group were located at the top of the femoral head, and the maximum displacement of the PFBN group was 14.373 mm, and the maximum displacement values of the PFNA and InterTan groups were 19.49 and 15.225 mm. For the stress distribution of intramedullary nail, the maximum stress of the three kinds of internal fixation was located on the main nail. The maximum stress of PFBN was 1191.8 MPa, compared with 2142.8 MPa for PFNA and 1702.3 MPa for InterTan. And the maximum stress on the PFBN pressure nail was 345.35 MPa, compared with 868.6 MPa for the PFNA spiral blade and 545.5 MPa for InterTan interlocking twin nails.

Conclusion

Compared with PFNA and InterTan, PFBN has better mechanical properties. The biomechanical characteristics of PFBN are more advantageous than PFNA and InterTan internal fixation system in the treatment of femoral intertrochanteric fractures.

Annual incidence of osteoporotic hip fractures in Iran: a systematic review and meta-analysis

Background

Osteoporosis (OP) is progressively becoming a global concern with the aging of the world’s populations. Osteoporotic fractures are associated with significantly increased mortality rates and a financial burden to health systems. This Meta-analysis aims to estimate the annual incidence of osteoporotic fractures in Iran.

Methods

A comprehensive systematic literature search was performed through Medline (PubMed), Embase, Scopus, Web of Science, and Google Scholar to identify studies which contain an investigation of the incidence of osteoporotic fractures in Iran up to December 3rd 2020, with no time and language restriction. For the risk of bias assessments of studies, the Joanna Briggs Institute (JBI) critical appraisal checklist for studies reporting prevalence data was used. The pooled estimation of the incidence of osteoporotic fractures in population aged≥50 years was calculated using random-effects meta-analysis, and the heterogeneity of included studies was quantified with the I² statistic.

Results

In all, 6708 papers were initially retrieved from the electronic databases, among which seven studies were included in the meta-analysis. The pooled standardized annual cumulative incidence of hip fractures was estimated as 138.26 (95% CI: 98.71–193.65) per 100,000 population and 157.52 (95% CI: 124.29–199.64) per 100,000 population in men and women, respectively.

Conclusion

This study showed a high incidence rate of osteoporotic hip fractures in Iran. Early detection and treatment of individuals with higher risks of primary fragility fractures at primary health care as well as implementing fracture liaison services to prevent secondary fractures are highly recommended. The results suffer from the following limitations: first, a low number of studies that were eligible for inclusion; second, the lack of population-based studies; and presence of highly heterogeneous studies despite the use of a random effect model.

Does the type of hip fracture affect functional recovery in elderly patients undergoing inpatient rehabilitation?

BACKGROUND

Hip fractures should not be considered as a single, homogeneous condition. Various determinants of functional recovery of patients with hip fracture have been proposed, such as age or type of fracture. The aim of this study was to determine if patients with an intertrochanteric fracture (ITF) had lower functional recovery characteristics with respect to those with a femoral neck fracture (FNF).

METHODS

A retrospective study was carried out on 531 elderly patients with hip fracture, surgically treated, admitted to a rehabilitation institute between December 1, 2014, and December 31, 2017. Patients underwent an individualized rehabilitation program for improving their physical function. The outcome measures of this study were the length of stay (LOS) in the rehabilitation institute, the Functional Independence Measure (FIM) gain, i.e. the difference in FIM score between discharge and admission, and the FIM efficiency, which represents the daily gain. Patients were also stratified by age categories and by different levels of functional independence, as evaluated with the FIM total score at baseline.

RESULTS

Age (p<0.05), LOS (p<0.005) and rehabilitation outcomes (FIM score and efficiency; p<0.05) differed significantly between patients with FNF and ITF. In particular, patients with ITF were older and more dependent at baseline. Moreover, they showed a lower FIM efficiency with respect to patients with FNF (p<0.05), which obtained a similar improvement in FIM total score of about 26 points but were discharged on average 3 days before. With aging, FIM efficiency decreased, while LOS increased. Patients highly dependent at baseline (FIM total score <40) had the lowest FIM gain and efficiency and the longest LOS respect to the more independent patients. Moreover, in older (85+ years) and in higher dependent patients the differences in the outcome measures between ITF and FNF were reduced.

CONCLUSIONS

The type of hip fracture could affect the LOS and FIM efficiency of younger and more independent patients with hip fracture during inpatient rehabilitation. In particular, patients with ITF require a longer rehabilitation period to achieve a similar functional gain as those with FNF.

Effectiveness in the Treatment of Intertrochanteric Fracture in Geriatric Patients by A Novel Prototype Carbon Composite External Fixator

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.

Gender and Age Differences in Hip Fracture Types among Elderly: a Retrospective Cohort Study

Objectives: To investigate the differences in distribution of intracapsular and extracapsular hip fractures among genders and age groups treated surgically. Materials and methods: This is a nine-year retrospective cohort study. The type of hip fractures, age, and sex-related as well as overall incidence among 2 430 patients aged over 65, surgically treated at the "Venizeleio" General Hospital of Heraklion, Crete, Greece, were explored and evaluated. Outcomes: Women suffered hip fractures 2.9 times more often than men. The majority of patients hospitalized with hip fracture were above 75 years of age (62.3% in females and 59.3% in males). The proportion of extracapsular and intracapsular fractures were 59.6% and 40.4% in men and 62.7% and 37.2% in women, respectively. Extracapsular-intertrochanteric fractures were found to increase dramatically with age in women (from 52.3% in patients younger than 75 to 58.8% in those older than 75; p-value=0.007), while in men they slightly increased with age (57.7% in patients older than 75, compared to 55.7% in those less than 75; p-value=0.62). Conclusion: The pattern of hip fractures was found to differ between genders and age groups in the present patients' population. Most likely, these findings reflect differences in the nature and rate of bone loss, and frequency of falling events between males and females. It has become evident that the two main hip fracture types (extracapsular and intracapsular) are distinct clinical entities. Hence, they should be addressed independently in terms of underlying causes and prevention strategies.

The Effect of Sensory Stimulation on Quality of Life of the Elderly and their Self-efficacy for Coping with the Fear of Falling

BACKGROUND

Aging causes major changes that affect the performance of all senses, and as a result, a critical change in the quality of life is expected. Falling and the fear of falling is one of the major health risks that affect the quality of life among elderly, threatening their independent living. This study was conducted to determine the role of sensory stimulation on the quality of life and self-efficacy in coping with fear in the elderly population.

MATERIALS AND METHODS

During this randomized controlled trial, 80 elderly volunteers from healthcare centers were divided into four intervention groups (music, photo album, aromatherapy, and hand massage) and one control group. Data collection was performed using the Older People's Quality of Life Questionnaire and Falls Efficacy Scale-International tools. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software program, version 16.0.

RESULTS

Comparing the scores of the quality of life and self-efficacy questionnaires, no statistically significant difference was reported among the groups (p < 0.05).

CONCLUSIONS

Sensory stimulation seems to have no impressive effect on the improvement of self-efficacy in coping with the fear of falling and the quality of life in the older population.

Three-Dimensional Microstructural Basis for Differential Occurrence of Subcapital versus Basicervical Hip Fractures in Men

We analyzed the bone microarchitecture of the subcapital and basicervical subregions of the femoral neck in men, to determine whether microarchitectural differences of cortical or trabecular bone can explain differential frequency of subcapital vs. basicervical fractures, especially in aged persons. The study sample encompassed twenty male proximal femora obtained during autopsy. They were divided in two age groups: young (< 40 years, n = 10) and aged (> 60 years, n = 10). Micro-computed tomography was used to evaluate cortical and trabecular microarchitecture of the subcapital and basicervical regions of the superolateral femoral neck-typical fracture initiation site. Basicervical region showed significantly thicker and less porous cortex than subcapital region (p = 0.02, p < 0.001, respectively), along with increased distance between cortical pores (p = 0.004) and smaller pore diameters (p = 0.069). Higher trabecular number (Tb.N: p = 0.042), lower trabecular thickness (Tb.Th: p < 0.001), and lower trabecular separation (p = 0.003) were also hallmarks of the basicervical compared to subcapital region, although BV/TV was similar in both regions (p = 0.133). Age-related deterioration was mostly visible in trabecular bone (for BV/TV, Tb.Th, Tb.N and fractal dimension: p = 0.026, p = 0.049, p = 0.059, p = 0.009, respectively). Moreover, there were tendencies to age-specific patterns of trabecular separation (more pronounced inter-site differences in aged) and cortical thickness (more pronounced inter-site differences in young). Trabecular microarchitecture corresponded to cortical characteristics of each region. Our study revealed the microarchitectural basis for higher incidence of subcapital than basicervical fractures of the femoral neck. This is essential for better understanding of the fracture risk, as well as for future strategies to prevent hip fractures and their complications.

Euthyroid sick syndrome in hip fractures: Valuation of vitamin D and parathyroid hormone axis

INTRODUCTION

Femur fracture is an acute event with a high incidence and mortality worldwide. Euthyroid sick syndrome (ESS) is a disease characterized by an alteration of fT3 in the absence of a primary thyroid pathology. The aim of the study is evaluating the association between femur fracture and ESS and post-operative fluctuations of the parathyroid hormone (PTH) and vitamin D and their physio-pathological implications.

MATERIALS AND METHODS

All patients older than 65 years, admitted in our emergency care unit with a diagnosis of proximal femur fracture were recruited. Exclusion criteria were acute cardio-pulmonary events, neoplastic diseases, any thyroid or endocrine pathology and use of drugs with thyroidal interactions. All patients underwent surgery within 48 h from the injury. The outcome of the study is the presence of ESS, moreover, post-operative fluctuations of the PTH and vitamin D are also evaluated.

RESULT

45 patients (13 men and 32 females) were enrolled. 20 patients had a normal thyroidal function, while 23 had a diagnosis of ESS. Mean age was 81.9. BMI was lower in the ESS group than the controls (25,3 vs 22,7; p < 0.02). In the ESS group a significantly higher decrease in Vitamin D levels was observed, compared to controls (3.96 ng/ml, p<0.001). Values of PTH were significantly different between the two groups, with a level 44.29 pg/ml lower among the ESS group compared to controls (p = 0.002). In the ESS group a significant decrease of serum calcium on the first post-surgery day was observed, compared to controls (8,7 vs 8,3; p < 0,01). There were no differences in the CCI, serum electrolytes and other variables collected between the two groups.

CONCLUSION

Part of the geriatric population suffering from fractures of the proximal femur are affected by ESS. This population displays anomalies of the Vitamin d-PTH axis and a lower BMI.

Functional outcomes after the treatment of hip fracture

Osteoporotic hip fracture is a major public health issue. Estimation of the outcome and maximization of functional recovery after fracture is very important in the treatment of older patients. The purposes of this study were to clarify the functional outcomes after the treatment of hip fracture and to identify the factors that influence functional recovery. In the present study, 228 patients admitted to an acute-care hospital from January 2016 to June 2018 were evaluated. The patients were categorized into a trochanteric fracture group (n = 128) and a neck fracture group (n = 100). We retrospectively reviewed their ambulation ability 6 months after fracture using the Functional Ambulation Category (FAC) score. The other survey items were the presurgical duration, length of hospital stay, time until beginning to walk using parallel bars, complications affecting treatment, and mortality rate. The 6-month follow-up rate was 54.4% (n = 124). The results showed that the patients with trochanteric fracture were significantly older than those with neck fracture (86 vs. 82 years, respectively; p = 0.03). In total, 85.0% of patients with trochanteric fracture and 92.2% of patients with neck fracture were independent ambulators before injury (FAC score of 4 or 5). The FAC score 6 months after fracture was positively correlated with the FAC score before fracture and at discharge (all p<0.001) and negatively correlated with patient age (p<0.001) and presurgical duration for patients with neck fracture (p = 0.04). There was no statistically significant correlation with the length of hospital stay or the time until beginning to walk using parallel bars. In conclusion, patients with trochanteric fractures were older than those with neck fractures. In both fracture types, walking recovery 6 months after hip fracture was related to the FAC score before injury and at discharge from an acute-care hospital but not to the time until beginning to walk using parallel bars.

Relationship between the AB0 Blood System and Proximal Femoral Fracture Patterns in the Turkish Population

Objective. AB0 blood groups have shown to be associated with increased risk of several orthopedic disorders such as Achilles tendon rupture and hip osteoarthritis. The objective of this study was to investigate relationships between the AB0 blood system and hip fracture patterns, duration of hospitalization, and amount of blood transfusion. Methods. Data of 308 patients treated due to hip fractures in our hospital between 2017 and 2019 were evaluated. Epicrisis reports and X-rays of the patients included in this study were retrospectively screened, and hip fractures were classified as intracapsular and extracapsular fractures. Patients were divided into A, B, 0, and AB groups according to blood groups. Results. The mean age of the patients was 75.54±13.5 years. Of all patients, 103 had an intracapsular fracture and 205 had an extracapsular fracture. No statistically significant correlation was found between blood groups and fracture patterns. No statistically significant difference was found between the amounts of transfusion according to the blood groups, and no significant difference between the durations of hospitalizations according to the blood groups. Conclusion. In our study population, we could not find a significant relationship between the AB0 blood system and fracture patterns. We think that these potential relationships could be explained with further comprehensive studies with larger populations.

Predisposing Factors and Outcomes After Prolonged Admission Following Hip Fracture

Introduction Hip fractures are increasingly prevalent and can result in substantial morbidity, mortality, and cost. Despite the existence of enhanced management strategies, prolonged hip fracture admissions persist. This study's objective was to ascertain characteristics associated with a prolonged length of stay (LOS) and quantify return to baseline once discharged. Methods A retrospective audit of hip fractures over a four-year period was conducted, identifying patients with a LOS over 100 days. Demographics, comorbidities, pre- and post-admission function, and status were assessed. Patients sustaining inpatient hip fractures were excluded to negate the effect of initial admission on LOS. Results Seven hundred and eleven hip fractures were treated, of which 48 (6.8%) were suitable for inclusion. The patients' median age and LOS was 83.5 years and 153 days, respectively. Preoperative American Society of Anesthesiologists - Physical Status (ASA-PS) Grades II and III predominated at 41.7% and 39.6%, respectively. Eighteen of patients had a diagnosis of dementia before admission, increasing to 29 on discharge (P = 0.0026). One patient was in long-term care prior to admission, rising to 30 on discharge (P < 0.0001), with only 25.6% returning to pre-admission residential status (P < 0.0001). Nineteen patients were mobilising unaided prior to admission, decreasing to only two following discharge, with a mere 37.1% returning to their pre-admission mobility baseline (P < 0.0001). Discussion Hip fracture patients with multiple comorbidities or a diagnosis of dementia were most likely to have a prolonged LOS which, in turn, impacted upon return to baseline mobility, cognitive status, and independence. Early identification and management of this cohort may help reduce the potential disease burden and economic effects that a prolonged LOS creates.

The role of parathyroid hormone (PTH) and vitamin D in falls and hip fracture type

BACKGROUND

Fragility fractures of the hip are associated with high morbidity and mortality, and represent a rather devastating consequence of osteoporosis. Hip fractures are traditionally investigated as a whole, although it has been recently implied that distinct pathogenic mechanisms may lead either to trochanteric or subcapital fractures.

AIMS

To investigate whether differences exist by hip fracture type with respect to serum 25(OH)D (vitamin D) and parathyroid hormone (PTH) levels, in addition to epidemiological and demographic data, including history of falls.

METHODS

The inclusion criteria were met by 116 patients [48 men and 68 women; mean age 80.8 ± 8.5 (range 62-94) years]. Patients were analyzed according to hip fracture type, history of falls, and vitamin D and PTH status.

RESULTS

Older age, recurrent falls, serum levels of PTH > 65 pg/ml, and severe vitamin D deficiency were found to be associated with trochanteric fractures. Additionally, older age, female gender, PTH > 65 pg/ml, and severe vitamin D deficiency were related to recurrent falls. Meanwhile, patients with absence of PTH response to low vitamin D levels, were not repeated fallers and suffered mostly from subcapital fractures.

DISCUSSION AND CONCLUSION

Elevated PTH levels predispose both to falls and trochanteric fractures, while vitamin D-deficient patients with normal PTH levels are mostly related to subcapital fractures. It is thereby indicated that different pathophysiological processes lie behind subcapital and trochanteric fractures. A better understanding of these mechanisms may assist in the development of prevention strategies for individuals recognized at risk for falls and either type of hip fracture.

The influence of ageing on the incidence and site of trauma femoral fractures: a cross-sectional analysis

Background

This study aimed to determine the influence of ageing on the incidence and site of femoral fractures in trauma patients, by taking the sex, body weight, and trauma mechanisms into account.

Methods

This retrospective study reviewed data from adult trauma patients aged ≥20 years who were admitted into a Level I trauma center, between January 1, 2009 and December 31, 2016. According to the femoral fracture locations, 3859 adult patients with 4011 fracture sites were grouped into five subgroups: proximal type A (n = 1359), proximal type B (n = 1487), proximal type C (n = 59), femoral shaft (n = 640), and distal femur (n = 466) groups. A multivariate logistic regression analysis was applied to identify independent effects of the univariate predictive variables on the occurrence of fracture at a specific site. A two-dimensional plot was presented visually with age and the propensity score accounts for the risk of a fracture at a specific femoral site.

Results

This analysis revealed that older age was an independent variable that could positively predict the occurrence of proximal type A (OR [95%CI]: 1.03 [1.03–1.04], p < 0.001) and B fractures (1.02 [1.01–1.02], p < 0.001), and negatively predict the occurrence of proximal type C (0.96 [0.94–0.98], p < 0.001), shaft (0.95 [0.95–0.96], p < 0.001), and distal fractures (0.98 [0.98–0.99], p < 0.001).

Discussion

Using the propensity scores which account for the risk of a fracture in a specific femoral site, this study revealed that the older patients were at a higher risk of developing proximal type A and type B fractures, while a lower risk of developing fractures in the shaft and distal femur. This incidence of fracture site can largely be explained by age-related factors, including a decrease in bone strength and falling being the most common mechanism of trauma in older patients.

Conclusions

This study revealed a difference in the involvement of age in the incidence of femoral fracture sites in the trauma patients.

Mediating Effect of Muscle on the Relationship of Physical Activity and Bone

PURPOSE

This study analyzed prospective associations between distinct trajectories of objectively measured physical activity (PA) and late adolescent bone parameters and explored the mediating effects of lean soft tissue, a surrogate of muscle mass to associations.

METHODS

Physical activity was measured by accelerometry starting at age 5 yr and continuing at 8, 11, 13, 15, and 17 yr in approximately 524 participants from the Iowa Bone Development Study. Sex-specific group-based trajectory modeling was used to construct developmental trajectories of moderate- and vigorous-intensity PA (MVPA) from childhood to late adolescence. At age 17 yr, proximal femur bone mineral density (aBMD) was assessed by dual X-ray energy absorptiometry, and its distribution was calculated by aBMD ratios. Specific geometric measures of the proximal femur were assessed using hip structural analysis.

RESULTS

A significant portion of the total effect of MVPA from age 5 to 17 yr on bone parameters at age 17 yr was explained by an increase in leg lean soft tissue in both sexes. For males and females, indirect effects were observed on the total and all regional proximal femur aBMD, and on the ratio between the inferomedial and superolateral neck aBMD. The effect on the ratio between the trochanter and the total proximal femur was specific to females, whereas the effect on the hip axis length was specific to males. Direct effects of MVPA on aBMD were identified only in males.

CONCLUSIONS

Using robust mediation analysis, this is the first study addressing the indirect effect (through muscle) of PA across childhood and adolescence on proximal femur bone parameters. To improve bone health at the proximal femur, the results suggest PA interventions during growth that increase muscle mass, particularly in females.

The Relationship Between BMI and Stability of Intertrochanteric Fracture Following Low-Energy Falls. A Retrospective Cohort Study

INTRODUCTION

Intertrochanteric proximal femur fractures are common injuries in the elderly. Certain patterns are considered unstable and confer increased risks. Risk factors for these patterns are not well defined. We sought to determine whether increased body mass index (BMI) was associated with increased risk of sustaining an unstable pattern intertrochanteric (IT) fracture following low-energy trauma. Materials and methods: Retrospective case review of all patients presenting to a level-2 trauma center between October 2010 and August 2014 with Intertrochanteric fracture. Fracture pattern (stable or unstable) and BMI were analyzed using odds ratios and age was controlled for.

RESULTS

Four hundred fifty-two patients were identified. No difference was found between fracture stability when BMI of 25 was used as a cutoff. However, when a BMI of 30 was used as a cutoff, there was a trend of difference (relative difference 30%) in rates of fracture type favoring unstable patterns in the obese group. This difference approached but did not reach statistical significance (P = .08). When adjusted for age, the difference remained but still did not reach statistical significance (P = .11).

DISCUSSION

Unstable type IT fractures were found more frequently in the obese cohort (BMI >30) than those who were not obese.

Spanish National Hip Fracture Registry (RNFC): analysis of its first annual report and international comparison with other established registries

Hip fracture registries have helped improve quality of care and reduce variability, and several audits exist worldwide. The results of the Spanish National Hip Fracture Registry are presented and compared with 13 other national registries, highlighting similarities and differences to define areas of improvement, particularly surgical delay and early mobilization.

INTRODUCTION

Hip fracture audits have been useful for monitoring current practice and defining areas in need of improvement. Most established registries are from Northern Europe. We present the results from the first annual report of the Spanish Hip Fracture Registry (RNFC) and compare them with other publically available audit reports.

METHOD

Comparison of the results from Spain with the most recent reports from another ten established hip fracture registries highlights the differences in audit characteristics, casemix, management, and outcomes.

RESULTS

Of the patients treated in 54 hospitals, 7.208 were included in the registry between January and October 2017. Compared with other registries, the RNFC included patients ≥ 75 years old; in general, they were older, more likely to be female, had a worse prefracture ambulation status, and were more likely to have extracapsular fractures. A larger proportion was treated with intramedullary nails than in other countries, and spinal anesthesia was most commonly used. With a mean of 75.7 h, Spain had by far the longest surgical delay, and the lowest proportion of patients mobilized on the first postoperative day (58.5%). Consequently, development of pressure ulcers was high, but length of stay, mortality, and discharge to home remained in the range of other audits.

CONCLUSIONS

National hip fracture registries have proved effective in changing clinical practice and our understanding of patients with this condition. Such registries tend to be based on an internationally recognized common dataset which would make comparisons between national registries possible, but variations such as age inclusion criteria and follow-up are becoming evident across the world. This variation should be avoided if we are to maximize the comparability of registry results and help different countries learn from each other's practice. The results reported in the Spanish RNFC, compared with those of other countries, highlight the differences between countries and detect areas of improvement, particularly surgical delay and early mobilization.

Functionality, comorbidity, complication & surgery of hip fracture in older adults by age distribution

BACKGROUND

Hip fractures may be the greatest complication secondary to osteoporotic disorder. The objective of this study was to determine the influence of age distribution in the functionality, comorbidity, complications and surgical features of older adults with hip fractures.

METHODS

A prospective cohort study was carried out from 2013 to 2014. A sample of 557 adults over 75 years old with osteoporotic hip fractures was recruited from the Orthogeriatric Unit of the León University Hospital (Spain). Age distributions of 75-84, 85-90 and >90 years old were considered. Firstly, sociodemographic data, fracture type and hospital staying days were collected. Secondly, baseline functionality (Barthel index), ambulation, cognitive impairment and comorbidities were described. Thirdly, surgical intervention, urgency, type, American Association of Anesthesiologists (ASA) scores, non-surgical cause, and baseline pharmacologic treatments were determined. Finally, complications and features at hospital discharge were observed.

RESULTS

The age ranges did not show any statistically-significant differences (P<.05; R2=.000-.005) for gender, fracture type, or number of hospital staying days. Statistically-significant differences (P<.05; R2=.011-.247) between age groups were observed for Barthel index, cognitive impairment, dementia, osteoporosis, Parkinson's disease, aortic stenosis, surgery type, ASA-score, non-surgical cause, benzodiazepines, antidementia, anti-osteoporosis, insulin, pharmacologic treatments, renal function alteration, heart failure, destination and ambulation features. All other measurements did not show statistically-significant differences (P>.05; R2=.000-.010).

CONCLUSION

Age distributions greater than 75 years old may determine the functionality, comorbidities, surgical features, baseline pharmacologic treatments, complications and features at hospital discharge for older adults who suffer a hip fracture.

Beyond orthogeriatric co-management model: benefits of implementing a process management system for hip fracture

Hip fracture is a major health care problem worldwide. Business process management systems (PMSs) have made significant contributions in health care environments to improve patient care standards. The effectiveness of PMS applied to hip fracture in older adults in the acute phase has been demonstrated.

INTRODUCTION

Fragility fracture is a major health care problem worldwide. Business PMSs have made significant contributions in health care environments to improve patient care standards. It is a new way of management that defines a homogeneous application procedure involving eliminating steps that add no value and developing explicit supervision criteria, in addition to identifying the appropriate managers.

PURPOSE

The aim of our trial was to assess the effectiveness of the PMS applied to hip fracture versus the orthogeriatric co-management model in the acute phase.

METHODS

All consecutive patients aged ≥ 65 who were admitted to Hospital Universitario Infanta Leonor between January 1, 2009, and December 31, 2016, for acute hip fracture surgery were included. We compared the effectiveness indicators in the acute phase between the preprocess period (orthogeriatric co-management) and the process period.

RESULTS

One thousand two hundred twenty-two patients were included (76.6% women). Mean age (SD) was 83.9 (6.4) years. Effectiveness management indicators are the following: length of hospital stay, time to admission to the ward from the emergency department, preoperative stay, surgery in < 48 h, and the operating room availability which were all improved in the process period with statistical significance. Effectiveness clinical indicators are the following: the numbers of patients with operated limb loading approved after surgery, discharged to home, and with osteoporosis treatment postfracture at the time of discharge which were statistically significantly higher in the process period, and the number of patients who suffered from delirium was statistically significantly lower in the process period. The number of in-hospital deaths was lower during the process period without statistical significance.

CONCLUSION

Our results demonstrated the effectiveness of the PMS applied to hip fracture in older adults compared with an orthogeriatric co-management model in the acute phase, based on both management indicators and clinical indicators.

Geriatric Patients with Hip Fracture: Frailty and Other Risk Factors Affecting the Outcome

BACKGROUND

Hip fracture is a devastating health-care problem in a geriatric patient, leading to high mortality and morbidity. Preoperative risk assessment in the geriatric patient is often inexact because of the difficulty in measuring their poor physiologic reserves.

AIMS

The primary objective was to find the association of modified frailty index (MFI) with 90-day mortality in geriatric patients who received anesthesia for fractured hip. Secondary objectives were to assess the association of preoperative waiting time with the 90-day mortality and the correlation of preexisting medical conditions with poor functional outcome among the survivors.

SETTINGS AND DESIGNS

This prospective, observational study was conducted at a tertiary care institution.

SUBJECTS AND METHODS

In this prospective observational study, done over a period of 1 year, 60 geriatric patients aged ≥65 years who received anesthesia for fractured hip and fulfilled selection criteria were recruited. The association of MFI with 90-day mortality and the correlation of preexisting comorbidities with poor functional outcome among the survivors were assessed.

STATISTICAL ANALYSIS USED

Independent sample t-test, Mann-Whitney test, and odds ratio were used as applicable.

RESULTS

Total 60 patients were available for analysis as two patients dropped off from final 62 on follow up, fifty three patients survived after 90 days. MFI and 90-day mortality showed a significant direct correlation with P < 0.0001. However, no association was found between the preoperative waiting time and 90-day mortality. Preexisting medical conditions showed a significant association of dementia with total dependence afterward with a P = 0.02.

CONCLUSION

There is significant statistical correlation of MFI with the 90-day mortality in the geriatric hip-fractured patients undergoing surgery.

Risk factors for trochanteric and femoral neck fracture

INTRODUCTION AND OBJECTIVES

The differences between the two main types of fracture of proximal end of the femur, trochanteric and cervical fractures, are still a subject of study, and could be the key to a better understanding of its pathophysiology and prevention. The aim of this study is to determine whether epidemiological differences in the distribution of risk factors associated with hip fracture exist between these two entities.

PATIENTS AND METHOD

A descriptive cross-sectional study of 428 patients over the age of 65 admitted for trochanteric or cervical fractures in 2015, in which gender, age, previous diagnosis, external causes associated with fracture and place of the event were recorded.

RESULTS

There were 220 patients with a cervical fracture (51.4%) and 208 patients with a trochanteric fracture (48.6%). The average age was higher in the trochanteric fracture, observing a constant increase with age only in women with trochanteric fractures. Cervical fracture showed a significant association with cerebrovascular disease (p=0.039) and trochanteric fracture with accidental falls (p=0.047) and presence of 5-9 previous diseases (p=0.014). A regression analysis maintained this association in the case of a cerebrovascular disease (OR 2.6, 95%CI 1.1-6.4) and the presence of 5-9 diseases (OR 1.5, 95%CI 1.1-2.3).

CONCLUSIONS

Trochanteric fractures are associated with women patients of more advanced ages, 5-9 previous diseases and accidental falls. Cerebrovascular disease shows a higher prevalence in cervical fractures.

Hip osteoarthritis as a predictor of the fracture pattern in proximal femur fractures

INTRODUCTION

Several authors have suggested a correlation between the fracture patterns of proximal femur fractures and the degree of hip osteoarthritis (HOA), but the current evidence to support this are insufficient. The aim of our study was to demonstrate whether there is an association between the grade of HOA and fracture pattern observed, in patients presenting with a fragility fracture of the proximal femur.

MATERIALS AND METHODS

We contacted a retrospective review of all patients presenting to our institution with fragility fractures involving the proximal femur, between March 2012 and October 2013. Pathological fractures, high-energy injuries and patients with less than one year of follow-up were excluded from further analysis. Admission radiographs and severity of HOA were assessed according to Kellgren and Lawrence scale (minimal: Grades 1-2; severe: Grades 3-4). Fractures were classified according to AO/OTA classification.

RESULTS

A total of 1003 patients (725 females; 1003 fractures) met the inclusion criteria, having a mean age of 81.5 (46-106 years). With regards to fracture classification, 417 (41.6%) fractures were classified as extracapsular and 586 (58.4%) as intracapsular. A total of 939 (93.9%) patients presented with minimal HOA, whilst 61 (6.1%) of the patients presented with severe HOA. Of the 61 patients presenting with severe HOA, 42 patients (68.9%) sustained a 31A-interthrocanteric fracture and 19 patients (31.1%) sustained a 31B-intracapsular fracture. Regarding the patients presenting with minimal HOA (832 patients in total), 323 patients (38.8%) sustained 31A-intertrochanteric fracture and 509 patients (61.2%) sustained a 31B-intracapsular fracture. Patients presenting with severe HOA were found to have a statistically significant chance to present with an extracapsular fracture (p<0.01).

CONCLUSIONS

The degree of HOA is related to the fracture pattern in patients presenting following simple mechanical falls. More specifically, higher grades of HOA are associated with extracapsular fracture patterns, whereas lower grades of HOA are associated with intracapsular fracture patterns.

Physical Activity for Strengthening Fracture Prone Regions of the Proximal Femur

PURPOSE OF REVIEW

Physical activity improves proximal femoral bone health; however, it remains unclear whether changes translate into a reduction in fracture risk. To enhance any fracture-protective effects of physical activity, fracture prone regions within the proximal femur need to be targeted.

RECENT FINDINGS

The proximal femur is designed to withstand forces in the weight-bearing direction, but less so forces associated with falls in a sideways direction. Sideways falls heighten femoral neck fracture risk by loading the relatively weak superolateral region of femoral neck. Recent studies exploring regional adaptation of the femoral neck to physical activity have identified heterogeneous adaptation, with adaptation principally occurring within inferomedial weight-bearing regions and little to no adaptation occurring in the superolateral femoral neck. There is a need to develop novel physical activities that better target and strengthen the superolateral femoral neck within the proximal femur. Design of these activities may be guided by subject-specific musculoskeletal modeling and finite-element modeling approaches.

Hip Fracture Types in Canadian Men and Women Change Differently with Age: A Population-Level Analysis

BACKGROUND

We have previously reported a gender difference in the occurrence of hip fracture type with age in our local population. In the current report, we have explored this phenomenon in a Canadian population using five years of data from a national administrative database. We have compared community-dwelling and institutionalized individuals to determine if frailty is important and has a differential effect on the type of hip fracture experienced.

METHODS

Hospitalization records from 2005 to 2009, in which the most responsible diagnosis, that is the diagnosis causing the admission to hospital, was a hip fracture, were obtained from the Discharge Abstract Database of the Canadian Institute for Health Information. Hip fracture type was identified using the Canadian Classification of Health Interventions and the International Classification of Diseases 10th Revision, Canada (ICD-10-CA). Hip fracture proportions were calculated for the study period and stratified by age group and sex.

RESULTS

The relative proportion of intertrochanteric fractures in women rose from 35% in the youngest group (55-59 years) to 51% in the oldest group (84+ years; P < 0.0001). In men, the proportions remain relatively stable (47% and 44%, respectively). Community and institutionalized patients showed the same pattern.

CONCLUSIONS

The change in the proportion of the two hip fracture types that occur in women but not men may point to differences in the etiology and consequently the approaches to prevention for the two fracture types. Level of frailty did not seem to be important.

Risk factors for hip fracture in very old people: a population-based study

SUMMARY

Knowledge of risk factors for hip fracture among very old people is limited. Walking indoors with help from ≤1 person, Parkinson's disease, currently smoking, delirium in the previous month, underweight, and age were associated with increased risk of hip fracture and could be important for preventive strategy development.

INTRODUCTION

The purpose of this study is to investigate risk factors for hip fracture among a representative sample of very old people.

METHODS

In total, 953 participants from the Umeå 85+/Gerontological Regional Database population-based cohort study were interviewed and assessed during home visits. Associations of baseline characteristics with hip fracture during the maximum 5-year follow-up period were analyzed using Cox proportional hazards regression.

RESULTS

Participants had a mean age of 89.3 ± 4.7 years; 65.8% were women, 36.8% lived in residential care facilities, 33.6% had dementia, and 20.4% had histories of hip fracture. During a mean follow-up period of 2.7 years, 96 (10.1%) individuals sustained hip fracture. Walking indoors with help from no more than one person (hazard ratio [HR] = 8.57; 95% confidence interval [CI], 1.90-38.71), Parkinson's disease (HR = 5.12; 95% CI, 1.82-14.44), currently smoking (HR = 4.38; 95% CI 2.06-9.33), delirium in the previous month (HR = 2.01; 95% CI, 1.15-3.49), underweight (body mass index <22; HR = 1.74, 95% CI, 1.09-2.77), and age (HR = 1.09; 95% CI, 1.04-1.14) were associated independently with an increased risk of hip fracture. Hip prosthesis at baseline decreased the risk of hip fracture (HR = 0.37; 95% CI, 0.15-0.91), but only for those with bilateral hip prostheses.

CONCLUSIONS

Seven factors were associated independently with incident hip fracture during follow-up in this sample of very old people. These factors could have important clinical implications in identifying persons at high risk of hip fracture, as well as in the development of effective preventive strategies.

Maxillofacial Fractures in Women and Men: A 10-Year Retrospective Study

PURPOSE

The purpose of this study was to evaluate and compare the demographic characteristics of maxillofacial fractures between women and men in China.

PATIENTS AND METHODS

The sample was composed of all patients who sustained maxillofacial fractures during a 10-year period (2000 through 2009). Incidences, age distributions, etiologies, fracture patterns, associated injuries, and occupation distributions were recorded and analyzed. Data analysis included the χ(2) test, the Fisher exact test, and the t test. A P value less than .05 was considered significant.

RESULTS

There were 1,131 patients (881 male and 250 female) who sustained maxillofacial fractures, with a male-to-female ratio of 3.5:1. Male patients sustained injuries most frequently during the autumn (P = .048), whereas female patients sustained more maxillofacial injuries during the summer (P = .006). Men sustained motorcycle (P = .023) and assault-related accidents (P = .036) more frequently than women, whereas women were more frequently injured in bicycle-related accidents (P < .001) or falling while at ground level (P = .001) than men. Women presented more frequently with condylar fracture than men (P = .028), whereas men were more prone to symphysis fractures than women (P = .037). For drivers, only men were involved (P = .001). Male workers sustained maxillofacial fractures more frequently than female workers (P < .001). Female children, students, and company staff were more prone to maxillofacial fractures than their male counterparts (P = .010, P = .004, and P = .044 respectively).

CONCLUSIONS

The demographic characteristics of maxillofacial fractures in female patients considerably differ from those in male patients.

The Effect of Skin Traction on Preoperative Pain and Need for Analgesics in Patients With Intertrochanteric Fractures: A Randomized Clinical Trial

BACKGROUND

Preoperative skin traction is applied for many patients with hip fracture. However, the efficacy of this modality in pain relief is controversial.

OBJECTIVES

The aim of the current study was to investigate the effects of skin traction on pain in patients with intertrochanteric fractures.

PATIENTS AND METHODS

A total of 40 patients contributed in this randomized clinical trial. Patients were randomly allocated into two equal groups: the skin traction (3 kg) and control groups. The severity of pain was recorded at admission and 30 minutes, one, six, 12, and 24 hours after skin traction application utilizing a Visual Analogue Scale (VAS). In addition, the number of requests for analgesics was recorded. Finally, the mean severity of pain in each measurement and the mean number of analgesic requests were compared between the two groups.

RESULTS

The severity of pain was significantly decreased in skin traction group only at the end of the first day after traction application (2.7 ± 0.8 vs. 3.3 ± 0.9; P = 0.042), while there was no significant difference between the two groups in other pain measurements. The number of requests for analgesics was the same between the two groups.

CONCLUSIONS

Although skin traction had no effect on analgesic consumption, it significantly decreased the pain at the end of the first day. The application of skin traction in patients with intertrochanteric fractures is recommended.

Distribution of vertebral fractures varies among patients according to hip fracture type

This study explored the distribution of vertebral fractures in hip fracture patients. Unlike patients with intertrochanteric fractures, those with subcapital fractures were less likely to have vertebral fractures in the T4-T10 region of the spine. The dissimilar distribution of vertebral fractures among patients with intertrochanteric and subcapital fractures may indicate different underlying etiologies.

INTRODUCTION

There are two main types of hip fractures: intertrochanteric and subcapital. Both types can have associated vertebral fractures. In this study, we explored the distribution of vertebral fractures in the two hip fracture populations.

METHODS

This was a retrospective analysis of a convenience sample of 120 patients: 40 with subcapital fractures and vertebral fractures, 40 with intertrochanteric fractures and vertebral fractures, and 40 with vertebral fractures only. Based on Genant's semiquantitative assessment method of radiographic images, the distribution and severity of each patient's vertebral fractures were explored [1].

RESULTS

Patients with subcapital fractures had significantly fewer total vertebral fractures (93 vs. 144, p = 0.005; 93 vs. 127, p = 0.019), vertebral fractures from T4 to T10 (41 vs. 81, p = 0.005; 41 vs. 64, p = 0.042), and vertebral fractures at the T7-T8 peak (11 vs. 31, p = 0.002; 11 vs. 30, p = 0.003) than patients with intertrochanteric fractures and those with vertebral fractures alone, respectively, and they were more likely to have only one vertebral fracture (15 vs. 3, p < 0.001; 15 vs. 2, p < 0.001). The number of vertebral fractures from T11 to L4 and at the T12-L1 peak did not differ among the groups. The numbers of fractures at each vertebral level was significantly correlated only between those with intertrochanteric fractures and those with vertebral fractures alone (r = 0.65, p = 0.009).

CONCLUSION

The distribution of vertebral fractures among patients with subcapital fractures differed from the other fracture groups, which may indicate that subcapital fractures and some lumbar fractures have a different underlying etiology than intertrochanteric fractures and thoracic (T4-T10) fractures.

Intra- and extra-capsular hip fractures in the elderly: Two different pathologies?

OBJECTIVES

To compare intracapsular (IC) and extracapsular (EC) hip fractures (HIF) in elderly patients in order to determine if they are different pathologies.

SUBJECTS AND METHODS

Longitudinal, observational, descriptive, analytical prospective design, using a non-probabilistic sample from a full sample collection with 647 subjects (male and female), of 60 or more years old, admitted with HIF to the Department of Orthopedics and Traumatology of the Hospital, between January 1, 2010 and December 31, 2012. Follow-up was for 1 year post HIF. Socio-demographic, etiological, developmental, therapeutic and prognostic variables are compared.

RESULTS

This is the first study on this subject with Latin American population. EC HIF incidence was superior to IC, contrary to that published in European/American populations. There are significant differences in etiological variables (χ(2)=6.34, p<0.042), with traumatic etiology in EC and non-traumatic in IC. There are also differences in therapeutic interventions performed (osteosynthesis for EC, arthroplasty for IC), with the decision on not to operate being lower in IC (both p<0.0000). The variables associated with the decision on not to perform surgery are age, etiology and postoperative mortality.

DISCUSSION

The results are similar to other studies, adding the IC association with non-traumatic origin, in particular the trend of statistical association between IC and non-primary osteoporotic pathology (neoplasms, renal osteodystrophy, primary hyperparathyroidism). A further analysis was performed on the differences between Latin American and European/American populations in the incidence of either type of HIF. There are important etiological and therapeutic differences between IC and EC HIF; therefore it would be advisable to consider them as distinct disease entities.

Association of ABO blood group with fracture pattern and mortality in hip fracture patients

INTRODUCTION

The mechanism of falling has been proposed as the exclusive explanation for hip fracture pattern. Evidence exists that other genetic factors also influence proximal femoral fracture configuration. The ABO blood group serotype has been associated with other pathologies but any role in hip fracture has yet to be definitively characterised.

METHODS

Our National Hip Fracture Database was interrogated over a four-year period. All patients had their blood group retrieved, and this was compared with hip fracture pattern and mortality rates. Confounding factors were accounted for using logistic regression and the Cox proportional hazards model.

RESULTS

A total of 2,987 consecutive patients presented to our institution. Those with blood group A were significantly more likely to sustain intracapsular fractures than 'non-A' individuals (p=0.009). The blood group distribution of patients with intracapsular fractures was identical to that of the national population of England. However, blood group A was less common in patients with intertrochanteric fractures than in the general population (p=0.0002). Even after correction for age and sex, blood group A was associated with a decrease in the odds of suffering an intertrochanteric fracture to 80% (p=0.002). Blood group A had inferior survivorship correcting for age, sex and hip fracture pattern (hazard ratio: 1.14, p=0.035). This may be due to associated increased prevalence of co-morbid disease in this cohort.

CONCLUSIONS

Blood group is an independent predictor of hip fracture pattern, with group A patients more likely to sustain an intracapsular fracture and non-A individuals more likely to sustain an intertrochanteric fracture. The determinants of fracture pattern are likely to be related to complex interactions at a molecular level based on genetic susceptibility. The mechanism of fall may not be the only aetiological determinant of proximal femoral fracture configuration.
