    1. Muscle size and density are independently associated with death after hip fracture: A prospective cohort study.
    期刊:Journal of cachexia, sarcopenia and muscle
    日期:2023-05-19
    DOI :10.1002/jcsm.13261
    BACKGROUND:Mortality following hip fracture is high and incompletely understood. We hypothesize that hip musculature size and quality are related to mortality following hip fracture. This study aims to investigate the associations of hip muscle area and density from hip CT with death following hip fracture as well as assess the dependence of this association on time after hip fracture. METHODS:In this secondary analysis of the prospectively collected CT images and data from the Chinese Second Hip Fracture Evaluation, 459 patients were enrolled between May 2015 and June 2016 and followed up for a median of 4.5 years. Muscle cross-sectional area and density were measured of the gluteus maximus (G.MaxM) and gluteus medius and minimus (G.Med/MinM) and aBMD of the proximal femur. The Goutallier classification (GC) was used for qualitatively assessing muscle fat infiltration. Separate Cox models were used to predict mortality risk adjusted for covariates. RESULTS:At the end of the follow-up, 85 patients were lost, 81 patients (64% women) had died, and 293 (71% women) survived. The mean age of non-surviving patients at death (82.0 ± 8.1 years) was higher than that of the surviving patients (74.4 ± 9.9 years). The Parker Mobility Score and the American Society of Anesthesiologists scores of the patients that died were respectively lower and higher compared to the surviving patients. Hip fracture patients received different surgical procedures, and no significant difference in the percentage of hip arthroplasty was observed between the dead and the surviving patients (P = 0.11). The cumulative survival was significantly lower for patients with low G.MaxM area and density and low G.Med/MinM density, independent of age and clinical risk scores. The GC grades were not associated with the mortality after hip fracture. Muscle density of both G.MaxM (adj. HR 1.83; 95% CI, 1.06-3.17) and G.Med/MinM (adj. HR 1.98; 95% CI, 1.14-3.46) was associated with mortality in the 1st year after hip fracture. G.MaxM area (adj. HR 2.11; 95% CI, 1.08-4.14) was associated with mortality in the 2nd and later years after hip fracture. CONCLUSION:Our results for the first time show that hip muscle size and density are associated with mortality in older hip fracture patients, independent of age and clinical risk scores. This is an important finding to better understand the factors contributing to the high mortality in older hip fracture patients and to develop better future risk prediction scores that include muscle parameters.

    2. Intramedullary Femur Nailing in Intertrochanteric Fractures: Postoperatively Do Helical Blades Migrate More Than Lag Screws? A Randomized Controlled Trial.
    期刊:Indian journal of orthopaedics
    日期:2023-04-29
    DOI :10.1007/s43465-023-00892-9
    Objectives:This was a prospective, randomized controlled trial to test functional outcomes between a single lag screw and helical blade nails in the treatment of intertrochanteric fractures. Methods:72 patients with intertrochanteric fractures between March 2019 to November 2020 were randomized into two groups and treated with a lag screw or a helical blade nail. Intraoperative parameters such as operative time, blood loss, and radiation exposure were calculated. Postoperatively, tip apex distance, neck length, neck-shaft angle, lateral impingement of implant, union rate, and the functional outcomes were measured at the end of 6 month follow-up period. Results:There was a significant decrease in tip apex distance ( = 0.03) and neck length(p-0.04) with significant lateral impingement of the implant ( = 0.04) in the helical blade group compared to the lag screw group. The functional outcome calculated using the modified Harris Hip score & Parker and Palmer mobility score, at the end of 6 months, had no significant difference between the two groups. Conclusion:Both lag screw and helical blade devices can be used to successfully treat these fractures, although there is greater medial migration in the helical blade as compared to the lag screw.

    3. Is sarcopenia associated with osteoporosis? A cross-sectional study of 262 women with hip fracture.
    期刊:European journal of physical and rehabilitation medicine
    日期:2022-04-12
    DOI :10.23736/S1973-9087.22.07215-X
    BACKGROUND:Several lines of evidence support the view that sarcopenia and osteoporosis are strictly connected. However, the capability of the updated sarcopenia definition to capture the concomitant presence of osteoporosis has been scarcely investigated. AIM:The main aim was to assess the association between sarcopenia defined according to the revised criteria from the European Working Group on Sarcopenia in Older People (EWGSOP2) and osteoporosis in women with a hip fracture. A second aim was to investigate the thresholds for low appendicular lean mass (aLM) and handgrip strength to optimize osteoporosis detection. DESIGN:Cross-sectional study. SETTING:Rehabilitation hospital. POPULATION:Women with subacute hip fracture. METHODS:A scan by dual-energy X-ray absorptiometry (DXA) was performed to assess body composition. A Jamar dynamometer was used to measure handgrip strength. Sarcopenia was diagnosed with both handgrip strength <16 kg and aLM <15 kg. Osteoporosis was identified with femoral bone mineral density lower than 2.5 standard deviations below the mean of the young reference population. RESULTS:We studied 262 of 290 women. Osteoporosis was found in 189 of the 262 women (72%; 95% CI: 67-78%) whereas sarcopenia in 147 (56%; 95% CI: 50-62%). After adjustment for age, time interval between fracture and DXA scan and body fat percentage the odds ratio to have osteoporosis for a sarcopenic woman was 2.30 (95% CI: 1.27-4.14; P=0.006). Receiver operating characteristic curve analyses showed that the best cut-off points to discriminate osteoporosis were 20 kg for handgrip strength and 12.5 kg for aLM. Adopting the optimized thresholds to define sarcopenia, the adjusted odds ratio to have osteoporosis for a sarcopenic woman was 3.68 (95% CI: 1.93-7.03; P<0.001). CONCLUSIONS:This preliminary study shows a positive association between sarcopenia defined according to the EWGSOP2 criteria and osteoporosis in 262 women with hip fracture. The association may be bettered by refining the cut-off points for low aLM and handgrip strength. CLINICAL REHABILITATION IMPACT:Sarcopenia seems to be a risk factor for osteoporosis in hip-fracture women. The issue, and the potential role of optimized thresholds should be addressed by robust longitudinal studies.

    4. Is central sarcopenia a predictor of prognosis for patients with pathological fracture?
    期刊:The surgeon : journal of the Royal Colleges of Surgeons of Edinburgh and Ireland
    日期:2022-04-13
    DOI :10.1016/j.surge.2022.03.005
    INTRODUCTION:We aimed to investigate the relationship between central sarcopenia and survival in patients with pathological fracture. METHODS:We reviewed records of patients who were treated for pathological fracture of axial and appendicular skeleton in our clinic between 2011 and 2020. We used the psoas: lumbar vertebral index (PLVI) on axial computer tomographic evaluation to assess for central sarcopenia. A multivariate Cox algorithm was applied to recognize these factors independently associated with one month, six months, one year, and overall survival. RESULTS:A total of 147 patients [61 (41.4%) male and 86 (58.6%) female] were included, with an average age of 62.4 years. During the study, 108 (73.4%) patients died, and 39 (26.6%) were alive. The survival rates at 1 month, 6 months, and 1 year after surgery were 94.6%, 68.7%, and 53.1%, respectively. PLVI values ranged from 0.21 to 1.20 with a mean of 0.536 and a median of 0.520. According to the median value of PLVI, 68 patients with sarcopenia had low PLVI and 79 patients without sarcopenia had high PLVI. For the first month, only the preoperative albumin level was identified as a prognostic factor. Eastern Cooperative Oncology Group Performance Status (ECOG), American Society of Anesthesia (ASA) scores and primary malignancy (rapid grade) were strong predictor of poor survival. The PLVI was independent significant predictor of first month (HR, 0.083 [95% CI, 0.011-0.649], p = 0.018) and overall survival (HR, 0.129 [95% CI, 0.034-0.492], p = 0.003). CONCLUSION:The PLVI was a strong predictor of first year, and overall survival in patients with pathological fracture.
