Patients with trochanteric hip fractures and pre-existing osteoarthritis can be treated with nailing osteosynthesis without significant decrease in functional status. Injury 2023; 54 Suppl 6:110735. [PMID: 38143114 DOI: 10.1016/j.injury.2023.04.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 03/25/2023] [Accepted: 04/12/2023] [Indexed: 12/26/2023]
Abstract
PURPOSE Functional outcome in patients after trochanteric fracture fixation with pre-existing radiographic osteoarthritis (OA) is unclear. Analyzing their function and independence, before and after fracture, could optimize their treatment and decrease the socioeconomic burden in this particular group. METHODS The influence of pre-existing radiographic hip OA on functional outcome was retrospectively analyzed with a cohort of patients undergoing proximal femoral nailing for trochanteric fracture. OA was graded according to the Tonnis classification. Functional outcome was assessed preoperatively and 12 months after surgery by the Parker Mobility Score (PMS). We consider a meaningful reduction a difference between preoperatively PMS and 12 months after surgery ≥ 2. In order to evaluate if OA is related to PMS reduction ≥ 2, we calculate the SubHazard ratio (SHR) performing a competing risk regression model considering death as a competing risk event, adjusting by confounders. Death, reoperations, readmissions, surgical time, and fracture reduction quality in patients with and without osteoarthritis were recorded. RESULTS 375 trochanteric hip fractures treated with cephalomedullary nails were included, from which 80 (21% CI95% 17%-21%) were classified as Tonnis 2 or 3. This group of patients with pre-existing OA was significantly older (mean age of 88.6 [SD 5.65] vs 85.5 years [SD 6.95]) than the group without OA. The preoperatively PMS score was 6.28 (2.71) in non-OA patients and 5.69 (2.67) in OA patients. The mean PMS reduction 12 months after surgery was 1.3 (SD 2.05) in OA patients and 1.07 (SD 2.2) in non-OA patients (p = 0.43). Competing risks analysis, adjusted by confounders had an SHR of 1.15 (IC95% 0.77 - 1.69). Death, readmission, reoperations, surgical time, and fracture reduction quality did not differ in both groups. CONCLUSIONS Patients with pre-existing radiographic OA treated with femoral nailing have a similar reduction in functional outcomes compared to the non-OA group at one-year follow-up. Further studies will be needed to compare the results of the functional outcome in arthroplasty with those of femoral nailing for the treatment of trochanteric femur fractures in patients with OA.

Short- and long-term prognostic factors associated with functional recovery in elderly patients with hip fracture: A systematic review. Osteoporos Int 2022; 33:1429-1444. [PMID: 35247062 DOI: 10.1007/s00198-022-06346-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 02/10/2022] [Indexed: 01/17/2023]
Abstract
UNLABELLED This systematic review aimed to identify short- and long-term associated factors to functional recovery of elderly hip fracture patients after discharge. We identified 43 studies reporting 74 associated factors to functional recovery; most of them were biological, sociodemographic, or inherent factors to patients' baseline characteristics, including their pre-facture functional capacity. PURPOSE This systematic review aimed to identify short- and long-term associated factors to functional recovery of elderly hip fracture patients after hospital discharge. We assessed the use of the hip fracture core-set and key-performance indicators for secondary fracture reduction. METHODS A search was performed in seven electronic databases. Observational studies reporting predictors after usual care of elderly patients with hip fracture diagnoses receiving surgical or conservative treatment were included. Primary outcomes considered were part of the domains corresponding to functional capacity. RESULTS Of 3873 references identified, and after the screening and selection process, 43 studies were included. Sixty-one functional measures were identified for ten functional outcomes, including BADLs, IADLs, ambulation, and mobility. Biological characteristics such as age, sex, comorbidities, cognitive status, nutritional state, and biochemical parameters are significantly associated. Determinants such as contact and size of social network and those related to institutional care quality are relevant for functional recovery at six and 12 months. Age, pre-fracture function, cognitive status, and complications continue to be associated five years after discharge. We found 74 associated factors to functional recovery of elderly hip fracture patients. Ten of the studies reported rehabilitation programs as suggested in KPI 9; none used the complete hip fracture core-set. CONCLUSION Most of the associated factors for functional recovery of elderly hip fracture were biological, sociodemographic, or inherent factors to patients' baseline characteristics, including their pre-facture functional capacity. For the core-set and KPI's, we found an insufficient use and report. This study reports 61 different instruments to measure functional capacity. REGISTRATION NUMBER PROSPERO (CRD42020149563).

[PMID: 32900470 DOI: 10.1016/j.injury.2020.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 06/24/2020] [Accepted: 09/02/2020] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Hip fractures are the most common fractures amongst frail older patients. Earlier studies have indicated an impaired hip flexion strength in patients with fractures that include detachment of the lesser trochanter. These patients may experience protracted functional impairment and longer recovery time, causing prolonged rehabilitation journeys. This study aimed to evaluate the effects of a detached lesser trochanter in trochanteric fractures on the recovery of hip function. METHOD A prospective observational cohort study was performed between 2016 and 2019. Community dwelling patients aged 70 years or older with AO 31A1-A3 trochanteric fractures were included. Patients followed routine care and were treated with a DHS or PFNA. The groups with and without involvement of the lesser trochanter were analysed. The primary outcome was hip function assessed at 6 weeks, 3 months and 1 year after surgery with the Harris Hip Score. Secondary outcomes included the Ludloff's test, complications, rehabilitation time, and pain-, independence-, and quality of life scores. A propensity score was used to adjust for any baseline differences between the two groups. RESULTS A total of 114 patients were included, 51 (44.7%) with involvement of the lesser trochanter and 63 (55.3%) without. Minor differences were observed in the baseline characteristics. No significant difference was observed for the Harris Hip Score (coefficient estimate: 3.31; 95% CI, -5.09-11.72; P = 0.43). The flexion function of the iliopsoas muscle was more often normal with the Ludloff's test in patients without involvement of the lesser trochanter (OR, 2.33; 95% CI, 1.241-4.387; P = 0.009). However, no differences were observed for any of the other secondary outcomes. CONCLUSION Although no differences in overall hip function were found, more hip fracture patients with involvement of the lesser trochanter showed prolonged impaired flexion of the hip. The absence of long-term, clinically relevant disadvantages however, proves fixing the lesser trochanter to be redundant.

Abstract
BACKGROUND Romosozumab is a bone-forming antibody that increases bone formation and decreases bone resorption. We conducted a double-blinded, randomized, phase-2, dose-finding trial to evaluate the effect of romosozumab on the clinical outcomes of open reduction and internal fixation of intertrochanteric or femoral neck hip fractures. METHODS Patients (55 to 94 years old) were randomized 2:3:3:3 to receive 3 subcutaneous injections of romosozumab (70, 140, or 210 mg) or a placebo postoperatively on day 1 and weeks 2, 6, and 12. The primary end point was the difference in the mean timed "Up & Go" (TUG) score over weeks 6 to 20 for romosozumab versus placebo. Additional end points included the time to radiographic evidence of healing and the score on the Radiographic Union Scale for Hip (RUSH). RESULTS A total of 332 patients were randomized: 243 to receive romosozumab (70 mg, n = 60; 140 mg, n = 93; and 210 mg, n = 90) and 89 to receive a placebo. Although TUG scores improved during the study, they did not differ significantly between the romosozumab and placebo groups over weeks 6 to 20 (p = 0.198). The median time to radiographic evidence of healing was 16.4 to 16.9 weeks across treatment groups. The RUSH scores improved over time across treatment groups but did not differ significantly between the romosozumab and placebo groups. The overall safety and tolerability profile of romosozumab was comparable with that of the placebo. CONCLUSIONS Romosozumab did not improve the fracture-healing-related clinical and radiographic outcomes in the study population. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
Objective To identify baseline factors relevant to functional outcomes and health‐related quality of life in the elderly with intertrochanteric fractures. Methods For the present study, 168 patients with intertrochanteric fracture who were assigned to different treatments between January 2016 and December 2017 were retrospectively selected. Hip function was assessed by Harris hip score (HHS), and health‐related quality of life was evaluated by Barthel index (BI) of activities of daily living (ADL) and EuroQol 5‐dimensions (EQ‐5D) score, respectively. Data were analyzed by t‐test, ANOVA, Pearson's correlation, χ2‐test, and multivariate linear regression. Results A total of 164 (97.6%) patients completed the follow‐up, with an average follow‐up time of 15.7 ± 6.9 months; 39 (23.8%) patients died during the follow‐up period and 125 (76.2%) patients were eligible for the functional analysis. HHS at final follow‐up of 125 patients was 71.8 ± 13.1, and the following were associated with hip functional recovery: age (−0.45, 95% confidence interval (CI) −0.73 to −0.18, P < 0.01), serum albumin (0.65, 95% CI 0.04 to 1.27, P < 0.05), and ADL at discharge (0.18, 95% CI 0.01 to 0.33, P < 0.05). The Barthel index at final follow up in this cohort was 80.2 ± 18.1, and multivariable linear regression analysis showed that age (−0.49, 95% CI −0.85 to −0.12; P < 0.05), ADL score at discharge (0.29, 95% CI 0.07 to 0.51; P < 0.05) and internal fixation (16.3, 95% CI 3.3 to 29.3; P < 0.05) were associated with ADL at final follow‐up. EQ‐5D at final follow‐up was 0.74 ± 0.2, with which HHS (0.012, 95% CI 0.011 to 0.013; P < 0.01) was positively associated. Conclusion We identify several baseline factors associated with hip functional outcome, health utility, and ADL in the elderly after an intertrochanteric fracture, of which we could modify mutable factors to achieve better outcomes. These findings could help to inform treatment and functional prognosis.

Abstract
Background Hip fracture is an important and prevalent medical condition associated with adverse outcomes. The aim of this article is to systematically review and summarise the predictors of poor functional outcomes and mortality for patients with hip fractures. Methods We conducted a systemic literature search using PubMed, EMBASE and Cochrane Library. We included English peer-reviewed cohort studies that examined predictors of poor functional outcomes (such as independence in Activities of Daily Living) and mortality for patients with hip fracture published in the past 15 years (from 1 Jan 2004 up to 30 May 2019). Two independent researchers evaluated the articles for eligibility. Consensus on the eligibility was sought and a third researcher was involved if there was disagreement. A standardised form was used to extract relevant data. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included studies. Results We retrieved 4339 and included 81 articles. We identified two emerging predictors of poor functional outcomes and mortality for patients with hip fractures: low hand grip strength and frailty in line with an emerging concept of “physical performance”. The predictors identified in this systematic review can be grouped into 1) medical factors, such as presence of co-morbidities, high American Society of Anesthesiologists (ASA) grade, sarcopenia, 2) surgical factors including delay in operation (e.g. > 48 h), type of fracture s, 3) socio-economic factors which include age, gender, ethnicity, and 4) system factors including lower case-volume centers. Conclusions This systematic review identified multiple significant predictors of poor functional outcomes and mortality, with the hand grip strength and frailty being important emerging predictors in the most recent literature. These predictors would further inform healthcare providers of their patients’ health status and allow for early intervention for modifiable predictors.

Abstract
OBJECTIVE The femoral neck-shaft angle (NSA) is an important measure for the assessment of the anatomy of the hip and planning of operations. Despite its common use, there remains disagreement concerning the method of measurement and the correction of hip rotation and femoral version of the projected NSA on conventional radiographs. We addressed the following questions: (1) What are the reported values for NSA in normal adult subjects and in osteoarthritis? (2) Is there a difference between non-corrected and rotation-corrected measurements? (3) Which methods are used for measuring the NSA on plain radiographs? (4) What could be learned from an analysis of the intra- and interobserver reliability? MATERIAL AND METHODS A systematic literature search was performed including 26 publications reporting the measurement of the NSA on conventional radiographs. RESULTS The mean NSA of healthy adults (5,089 hips) was 128.8° (98-180°) and 131.5° (115-155°) in patients with osteoarthritis (1230 hips). The mean NSA was 128.5° (127-130.5°) for the rotation-corrected and 129.5° (119.6-151°) for the non-corrected measurements. CONCLUSION Our data showed a high variance of the reported neck-shaft angles. Notably, we identified the inconsistency of the published methods of measurement as a central issue. The reported effect of rotation-correction cannot be reliably verified.

Abstract
BACKGROUND The influence of pre-existing radiographic osteoarthritis on the functional outcome of elderly patientents with displaced intracapsular fractures of the femoral neck treated by hemiarthroplasty is unclear. METHODS We prospectively examined the impact of pre-existing osteoarthritis on the functional outcome of 126 elderly patients with displaced intracapsular fracture of the femoral neck treated by hemiarthroplasty. RESULTS The mean age of the cohort was 82.7 years. At 12 months, we observed no statistically significant differences in the Harris hip score (p = 0.545), the timed up and go test (p = 0.298), the Tinetti test (p = 0.381) or the Barthel Index (p = 0.094) between patients with Kellgren and Lawrence grades 3 or 4 osteoarthritis, and patients with grades 0 to 2 changes. Furthermore, there were no differences in complication or revision rates. CONCLUSIONS Our findings challenge the hypothesis that pre-existing osteoarthritis is a contraindication to hemiarthroplasty in elderly patients with femoral neck fracture.

Abstract
PURPOSE Inadequate reconstruction of femoral offset after total hip arthroplasty (THA) is associated with unfavourable outcomes, but its importance following hemiarthroplasty for displaced femoral neck fracture is unknown. METHODS Our study examined the correlation between reconstructed femoral offset and functional outcome 12 months after post traumatic hemiarthroplasty in 126 prospectively enrolled elderly patients. Rotation-corrected femoral offset (FORC), relative femoral offset (FORL) and contralateral femoral offset (FOC) were measured on anteroposterior radiographs. The Harris Hip Score (HHS) was the primary outcome measure; the timed up and go (TUG) test and Lawton instrumental activities of daily living (IADL) score were secondary outcomes. Correlations were sought using the Spearman correlation coefficient (r). Sample size was calculated using an Altman nomogram, with the power set at 80 %, the significance level of 0.05 and a standardised difference of 0.75. RESULTS The mean reconstructed FORC was 41 mm (17-67 mm) and showed a linear relationship and excellent correlation with the FOC. At 12 months, we found a significant positive correlation between FORC and HHS (r = 0.303, p = 0.025) and IADL (r = 0.325, p = 0.013), but not TUG (r = -0.026, p = 0.863). These findings were confirmed by bivariate and multivariate correlation between FORL and functional outcome parameters. CONCLUSIONS We found a clinically relevant relationship between femoral offset and functional outcome after hemiarthroplasty in elderly patients, comparable with that of THA, for treating osteoarthritis.
