Lateral femoral wall thickness in trochanteric hip fractures: a systematic review.

BACKGROUND: Thin lateral femoral wall has been investigated as a sign of instability in trochanteric hip fractures, necessitating lateral wall reconstruction or the use of a cephalomedullary nail (CMN). Various cut-off values have been proposed to guide implant choice. This review aims to determine the clinical significance of the lateral femoral wall thickness (LWT) in trochanteric hip fractures and identify an optimal cut-off value for increased risk of lateral wall (LW) fracture when using Dynamic Hip Screw (DHS). METHODS: A comprehensive search was conducted in databases including Medline, Embase, and the Cochrane library up to July 2023. A predefined strategy was employed, with 5 eligible studies critically appraised using the methodological index for non-randomized studies (MINORS) criteria. Outcomes assessed encompassed the standardised mean difference (SMD) of LWT between the LW fracture and non LW fracture groups, aggregate LWT mean in LW fracture group, and the relation between AO/OTA fracture type with LW fracture utilising the chi-square test. RESULTS: Among 481 patients from 5 studies, 112 experienced LW fractures, while 369 did not postoperatively. Analysis indicated a significantly lower LWT in the LW fracture group (SMD -1.13, I² = 41.3%, p = 0.146). The mean LWT in the LW fracture group was 18.2 mm, with a 95% confidence interval of 17.29-19.10 mm. CONCLUSIONS: A preoperative thin lateral femoral wall is a critical predictor of fixation failure and suboptimal functional outcomes when using a DHS. Thorough evaluation of pre- and intraoperative x-rays is essential. CMN is recommended over DHS in cases with LWT measurements <19 mm.

The Impact of the COVID-19 Pandemic on One-Year Mortality in Geriatric Hip Fracture: A Retrospective Cohort Study.

Introduction: The COVID-19 pandemic has profoundly impacted global healthcare systems, necessitating substantial shifts in patient care strategies. The pandemic's onset led to drastic operational changes in hospitals, including reduced bed capacity and staffing levels, which could have further influenced the mortality outcomes for geriatric patients. The study aimed to assess the impact of the COVID-19 pandemic on 1-year mortality rates of surgically treated geriatric hip fractures. Methods: This retrospective, single-center cohort study included 346 participants aged 65 and above who underwent surgical treatment for hip fractures. We compared mortality rates between the pre-COVID and COVID eras. Data included demographics, treatment, complications, and COVID-19 status. The independent samples t test and Chi-square tests (or Fisher's exact test) were used for comparisons for era cohorts. Survival probabilities were assessed using Kaplan-Meier, while multivariate analysis identified mortality predictors. Results: 175 patients were included in the pre-COVID era, and 171 patients were included in the COVID era. During the COVID era, the 30-day mortality rate was 11.7% (compared to 13.7% in the pre-COVID era, p = 0.573), and the 1-year mortality rate was 43.9% (compared to 49.1% in the pre-COVID era, p = 0.325). The overall 1-year mortality rate was 46.5%. Patients who underwent surgery within 48 hours had a higher 1-year survival rate (60.5%) compared to those with delayed surgery (51.2%), p = 0.031. Additionally, patients not admitted to the ICU had a higher 1-year survival rate (74.7%) than those who were admitted (44.9%), p < 0.001. 70.1% of the total deaths occurred within the first 90 days. Conclusion: Elderly patients with hip fractures experienced high mortality rates before and during the pandemic. This study demonstrates that the 1-year mortality rates of geriatric hip fractures were not significantly affected by the pandemic. The findings emphasize the importance of pandemic preparedness and prompt surgeries and attentive ICU care in reducing mortality rates.

Patient Satisfaction Following Non-Operative Treatment of Geriatric Hip Fractures: A Case-Control Study.

Introduction: A minority of geriatric hip fracture patients pursue non-operative treatment. Compared with surgical patients, non-operative patients have higher mortality rates. However, patient satisfaction following non-operative vs operative treatment has not been investigated extensively. The purpose of this study was to compare satisfaction among non-operatively vs operatively treated hip fracture patients. Methods: We identified patients aged 60+ years with proximal femur fractures treated over a 10-year period. Excluded were patients with isolated greater/lesser trochanteric fractures. Patients or relatives were asked to complete a 6-question survey about their treatment satisfaction. Results: Survey responses from 56 operative and 28 non-operative patients were recorded. Overall, 91.1% of operative and 82.1% of non-operative patients were satisfied with their treatment course (P = 0.260). However, only 71.4% of non-operative patients were satisfied with treatment option explanations vs 83.9% of operative patients (P = 0.014). While only 64.3% of non-operative respondents were satisfied with the ultimate treatment outcome (vs 85.7% of operative patients, P = 0.025), 89.3% of patients in each cohort would choose the same treatment plan again. Discussion: Our findings highlight the complexity of defining patient satisfaction, particularly in a geriatric hip fracture population. Unlike previous studies, we chose a direct approach to quantifying patient satisfaction by asking participants specifically about satisfaction with treatment outcome and the overall treatment course. Additional survey questions were then included to assess factors considered important in treatment satisfaction, such as health care provider treatment explanations, post-treatment mobility, and palliative care service involvement. Conclusions: We identified significant differences between non-operatively and operatively treated geriatric hip fracture patients regarding satisfaction with the explanation of treatment options, and ultimate treatment outcomes. There was no significant difference in overall satisfaction with the treatment course or likelihood of choosing the same treatment again. Further research investigating patient satisfaction following geriatric hip fracture treatment is warranted.

Enhanced recovery after surgery speeds up healing for hip fracture patients.

OBJECTIVE: To investigate the effects of enhanced recovery after surgery (ERAS) on the perioperative healing and stress response in patients with hip fractures. METHODS: A retrospective analysis was conducted on the medical records of 86 patients with hip fractures admitted to the Affiliated Hospital of Southwest Medical University between January 2022 and August 2023. Among them, 48 patients in the research group received ERAS, while 38 patients in the control group received conventional nursing. Hip joint function, pain levels, stress response, fracture healing time, incidence of complications, and nursing satisfaction were compared between the two groups. RESULTS: After nursing, the Harris scores notably increased in both groups, with the research group showing notably higher scores compared to the control group (P<0.05). The levels of cortisol and epinephrine, as well as the visual analog scale scores significantly decreased in both groups, with the research group showing significantly lower levels (P<0.05). In addition, the research group experienced significantly shorter fracture healing time (P<0.05), higher nursing satisfaction (P=0.014), and lower incidence of complications (P=0.028). Logistic regression analysis revealed that age, underlying diseases, nursing method, emotional disorders, and timing of surgery were independent factors influencing the post-nursing outcomes. CONCLUSION: The ERAS mode can effectively alleviate pain, improve hip joint function, reduce fracture healing time and complications, mitigate stress response, and accelerate postoperative recovery in patients with hip fractures. It is worthy of application and promotion in clinical practice.

Preoperative cardiology consultations for geriatric patients with hip fractures rarely provide additional recommendations and are associated with prolonged hospital stays and delayed surgery: a retrospective case control study.

OBJECTIVES: Hip fractures are increasingly common among the elderly population, who often present with a high burden of comorbidities necessitating preoperative stabilization. As a result, preoperative cardiology consultations are frequently conducted in clinical practice. The aim of this study was to investigate the additional recommendations provided by preoperative cardiology consultations and the impact of consultations on the management and outcomes of elderly patients undergoing hip fracture surgery. PATIENTS AND METHODS: This matched cohort study was performed to retrospectively assess the clinical data of patients who were treated for hip fractures at our institution between January 2016 and December 2017. Individuals who were 60 years old or older with available clinical and radiological data were included. A total of 262 patients who met these criteria were included, with 192 undergoing cardiology consultation and 70 not. Through matching for age, sex, ASA grade, fracture type, and surgery type, two groups (Group A, preoperative cardiology consultation requested; Group B, preoperative cardiology consultation not requested) of 50 patients each were formed. The duration between hospital admission and surgery, recommendations provided by cardiology consultation, type of anaesthesia and surgery, length of hospital stay, incidence of medical and orthopaedic complications, and one-year mortality status were compared between the groups. RESULTS: The mean age of Group A was 78.5 (± 7.4) years, whereas that of Group B was 78.4 (± 7.4) years (p = 0.99). Both groups included 30 female patients and 20 male patients each. There were no significant differences in anaesthesia type or the incidence of medical or orthopaedic complications between the groups. However, Group A experienced a significantly longer duration between admission and surgery (5 [1/9] days vs. 3 [0/7] days; p = 0.00) and a longer hospital stay (7 [3/15] days vs. 5 [1/19] days; p = 0.01) than did Group B. The one-year mortality rate did not significantly differ between the groups (30% vs. 20%; p = 0.36). Notably, only 3 out of 50 patients received additional treatments following cardiology consultation beyond routine recommendations. CONCLUSION: Preoperative cardiology consultations before hip fracture surgery rarely leads to a change in treatment. Additionally, these evaluations delay surgery and extend the hospital stay.

Developing a consensus-based motivational care pathway for individuals with lower limb fractures: a Delphi protocol.

Older adults with lower limb fractures often harbor concerns about losing their mobility, fearing a loss of independence. It is vital to develop strategies that foster their active engagement in the rehabilitation process. The present protocol aims to create a care pathway tailored to motivate individuals with lower limb fractures to adhere to rehabilitation. We will develop an observational, cross-sectional, and descriptive study using the Delphi data-gathering approach. Purposive sampling will recruit a panel of healthcare professionals and experts who care for patients with lower limb fractures. Aligned with the Delphi method, a series of iterative rounds will be developed to gather consensus around the motivational strategies used by health professionals in the rehabilitation of people with lower limb fractures. We will employ the Qualtrics platform for data collection and analysis, and a consensus target of 75% has been predetermined. For quantitative data analysis, we will use descriptive statistics encompassing a range of measures, including count, mean, standard deviation, median, minimum, maximum, and range. An inductive thematic analysis procedure will be employed to extract meaningful themes and patterns from qualitative data. The study results are expected to significantly impact clinical practice by creating a specialized care pathway to motivate individuals with lower limb fractures to adhere to rehabilitation. Adopting these explicit standards by professionals will ensure uniform and high-quality care.

Phase Angle as a Predictor of Mortality in Older Patients with Hip Fracture.

The aim of our study is to determine if there is an association between phase angle obtained by bioelectrical impedance analysis (BIA) and mortality in older patients with fragility hip fractures. A prospective study of patients over 65 years old and hospitalized with a diagnosis of hip fracture was conducted. BIA was performed 24 to 48 h after surgery. Mortality was recorded, and the optimal phase angle cut-off value for predicting mortality was determined by using receiver operating characteristic (ROC) curves. A total of 262 patients were included. Of the patients studied, 10 (3.8%), 21 (8%), 39 (14.9%) and 53 (20.2%) died at 1, 3, 6 and 12 months after surgery, respectively. The phase angle cut-off for mortality at 12 months was 4.05° in women and 4.65° in men. A total of 94 patients (35.9%) were considered to have a low phase angle. After adjustment for possible confounders, mortality in patients with a low phase angle was 5.1 times higher at 1 month, 3.1 times higher at 3 months, 2.9 times higher at 6 months, and 2.8 times higher at 12 months. Phase angle is associated with prognosis in patients admitted for hip fracture regardless of age and comorbidities and can be positioned as a prognostic tool for mortality at 1, 3, 6 and 12 months.

Comparative analysis of geriatric hip fracture management outcomes in teaching and nonteaching hospitals in Jordan.

Hip fractures are common orthopedic injuries that have significant impacts on patients and healthcare systems. Previous studies have shown varying outcomes for hip fracture management in different settings, with diverse postoperative outcomes and complications. While teaching hospital settings have been investigated, no studies have specifically examined hip fracture outcomes in teaching hospitals in Jordan or the broader Middle East region. Therefore, the aim of this study was to investigate this important outcome. A cohort comprising 1268 patients who underwent hip fracture fixation from 2017 to 2020 was analyzed for nine distinct outcomes. These outcomes encompassed time to surgery, ICU admissions, perioperative hemoglobin levels, length of hospital stay, readmission rates, revision procedures, and mortality rates at three time points: in-hospital, at 6-months, and at 1-year post-surgery. The analysis of 1268 patients (616 in teaching hospitals, 652 in non-teaching hospitals) showed shorter mean time to surgery in teaching hospitals (2.2 days vs. 3.6 days, p < 0.01), higher ICU admissions (17% vs. 2.6%, p < 0.01), and more postoperative blood transfusions (40.3% vs. 12.1%, p < 0.01). In-hospital mortality rates were similar between groups (2.4% vs. 2.1%, p = 0.72), as were rates at 6-months (3.1% vs. 3.5%, p = 0.65) and 1-year post-surgery (3.7% vs. 3.7%, p = 0.96). Geriatric hip fracture patients in teaching hospitals have shorter surgery times, more ICU admissions, and higher postoperative blood transfusion rates. However, there are no significant differences in readmission rates, hospital stays, or mortality rates at various intervals.

Predictive value of prognostic nutritional index on postoperative intensive care requirement and mortality in geriatric hip fracture patients.

OBJECTIVE: The incidence of postoperative morbidity and mortality in hip fracture patients is high and is associated with nutritional deficiencies. This study investigated the predictive value of preoperative prognostic nutritional index (PNI) on postoperative intensive care unit (ICU) requirement and mortality in geriatric hip fracture patients. METHODS: Geriatric (≥65 years old) hip fracture patients who underwent surgery between January 2021 and September 2023 were evaluated retrospectively. Patients were classified according to the unit followed in the postoperative period (service group and ICU group) and 28-day mortality (mortality group and survivor group). The predictive value of PNI for ICU requirement and mortality and the factors affecting ICU requirement and mortality were investigated. RESULTS: The study included two hundred twenty-two patients, and 66.2% (n=147) were women. In the postoperative period, 47.7% (n=106) of the patients were followed in the ICU and 52.3% (n=116) in the inpatient service. The 28-day mortality of the patients was 6.8% (n=15). PNI was found to be significantly lower in patients followed in the ICU (group ICU) than in those followed in the service (group S) and in patients who died (group mortality) compared to those who lived (group survivor) (p<0.001 and p=0.029, respectively). In multivariate regression analysis, high American Society of Anesthesiologists (ASA) status and low PNI were determined to be independent risk factors for ICU requirement. Acute Physiology and Chronic Health Assessment II score was an independent predictor of mortality. In ROC curve analysis, the cut-off value of PNI in predicting mortality was 32.5, and the area under the curve was 0.660 (95% CI, 0.516-0.803). CONCLUSION: In geriatric hip fracture patients, preoperative PNI value can be used, like ASA status, in determining postoperative ICU requirements. Nutritional deficiencies are associated with adverse postoperative outcomes in this patient group, and low PNI values (<32.5) help predict in-hospital mortality.

Which factor is more associated with survival of patients with hip fracture over 90 years: Type of fracture or treatment modality?

OBJECTIVE: We aimed to analyze prognostic factors affecting the mortality and to evaluate whether the fracture type (collum femoris or intertrochanteric fracture) or treatment method (proximal femoral nail or hemiarthroplasty) affects the mortality in patients with hip fractures and older than 90 years old. METHODS: In our study, we retrospectively reviewed the patients aged >90 years and operatively treated hip fractures. Patients were categorized according to fracture type and treatment method. Finally, three groups were created. Demographic values, laboratory values were analyzed for prognostic factors and determining independent factors associated with survival for each group. RESULTS: A total of 193 patients were included with an average age of 92.5±2.4 (range, 90-104) years. There were 144 women and 49 men. There were 126 (65.2%) patients with intertrochanteric fracture and 67 (34.8%) patients with collum femoris fracture. At the time of this study, 142 (73.5%) patients had deceased. Staying in intensive care unit for collum femoris group, general anesthesia for intertrochanteric fracture treated with hemiarthroplasty group and delay to surgery and preoperative albumin level for intertrochanteric fracture treated with proximal femoral nail group were associated with poor survival. CONCLUSION: Staying intensive care unit, general anesthesia, delay to surgery and preoperative albumin levels should be carefully evaluated for patients aged over 90 years with hip fractures. Our study showed that both fracture type and treatment modality were not associated with poor overall survival of the patients aged >90 years following hip fracture surgery.

Two-year outcomes of internal fixation with femoral neck system in patients with femoral neck fracture in an Asian population.

Background: Femoral neck fractures (FNF) are one of the most common fractures, with a projected increase in incidence with population growth and ageing. The Femoral Neck System (FNS) launched in 2019 was developed specifically for fixation of FNF with the purported advantages of providing both angular and rotational stability. We report our experience with the FNS and evaluate its effectiveness and associated complications. Methods: A retrospective case series of 50 patients who underwent surgical fixation for FNF from August 2020 to October 2021 using the FNS in two Singapore tertiary institutions with at least 2 years follow-up were included. Clinical data (patients' demographics, fracture classification, intra-operative and post-operative complications) were reviewed. Radiological analysis assessed the pre- and immediate post-operative garden alignment index (GAI) and presence of femoral neck shortening at 3 months. Results: The mean age was 63.5 years (SD 16.9, range 26-92). Five (10 %), 34 (68 %) and 11 (22 %) were ASA 1, 2 and 3 respectively. Twenty-four (48 %), 16 (32 %), 4 (8 %), and 6 (12 %) patients sustained Garden's 1, 2, 3 and 4 FNF respectively. The mean operative duration was 66.2 min (SD 20.5) and length of stay was 6.9 days (SD 4.6).The post-operative improvement in garden alignment index (GAI) was a mean of 9.1° (p < 0.001) on lateral view. The mean femoral neck shortening was 1.97 mm (SD 5.3) at 3 months. There were no intra-operative complications. Post-operatively, 1 (2 %) patient required blood transfusion, 1 (2 %) patient had implant cut-out and non-union managed non-operatively, 2 (4 %) patients developed avascular necrosis and required revision to total hip replacements. There were two (4 %) cases of 1-year mortality. Conclusion: The FNS achieved good outcomes with low rates of complications. The promising results justify its continued use and further evaluation in comparison to other devices.

Vitamin D Supplementation and the Incidence of Fractures in the Elderly Healthy Population: A Meta-analysis of Randomized Controlled Trials.

INTRODUCTION: Although a well-established component of bone metabolism, the efficacy and safety of vitamin D supplementation for the prevention of fractures in elderly healthy individuals is still unclear. PURPOSE: To perform a meta-analysis comparing vitamin D supplementation with placebo and its contributions on fracture incidence. METHODS: This meta-analysis was registered in the International Prospective Register of Systematic Reviews (PROSPERO), under protocol CRD42023484979. We systematically searched PubMed, Embase, and Cochrane Central databases from inception to November 2023 for randomized controlled trials (RCTs) comparing vitamin D supplementation versus placebo in individuals with 60 years of age or more and without bone related medical conditions such as cancer and osteoporosis. RESULTS: Seven RCTs with 71,899 patients were included, of whom 36,822 (51.2%) were women. There was no significant difference in total fracture incidence (RR 1.03; 95% CI 0.93-1.14; p = 0.56; I2 = 58%) between groups or subgroups. However, women had an increased risk for hip fractures (164 vs. 121 events; RR 1.34; 95% CI 1.06-1.70; p = 0.01; I2 = 0%). There was no significant difference in non-vertebral fractures, osteoporotic fractures development, or falls (RR 1.02; 95% CI 0.94-1.12; p = 0.6; I2 = 47%; RR 0.97; 95% CI 0.87-1.08; p = 0.63; I2 = 0%; RR 1.01; 95% CI 0.97-1.04; p = 0.66; I2 = 55%, respectively). CONCLUSION: Vitamin D supplementation does not reduce the total fracture development rate in the elderly healthy population, and it may increase the incidence of hip fractures among elderly healthy women. This finding suggests refraining from prescribing high intermittent doses of vitamin D, without calcium, to individuals aged 60 or older with unknown vitamin D serum concentration or osteoporosis status and inadequate calcium intake.

Prevalence and risk factors for atypical femoral fracture among Lebanese patients with hip and shaft fractures.

This retrospective study investigates the prevalence of atypical femoral fractures (AFFs) among patients admitted with hip and shaft fractures at a tertiary referral center in Beirut, Lebanon. We analyzed electronic medical records and radiology studies of patients aged above 40 admitted with hip and shaft fractures between January 2006 and December 2019. Fractures were confirmed by ICD9 or ICD10 codes. All cases were reviewed by radiologists, and AFFs were identified according to the 2013 revised ASBMR criteria. We identified 1366 hip and shaft fracture patients, of which 14 female patients had 19 AFFs. This represents a prevalence of 1.0% among all hip and shaft fractures patients and 1.7% among all female hip and shaft fracture patients. Bilateral AFFs were found in 5 of the 14 patients. Patients with AFF tended to be younger, with a mean age of 74.3 (±8.6) yr compared to 78.0 (±10.6) for patients with non-AFF fractures. A total of 36% of AFF patients had a prior history of non-traumatic fracture at first admission. A high percentage of patients with AFFs reported intake of proton pump inhibitors (42.9%) and glucocorticoids (21.4%). Bisphosphonate exposure was noted in 64.3% of AFF patients. None of the AFF patients were active smokers or consumed alcohol regularly. BMD assessments were available for 7 AFF patients, indicating osteoporosis in 4 and osteopenia in 3 cases. Hip axis length measurements showed no significant difference between AFF patients (N = 7) and sex and age-matched controls (N = 21). The study underlines the prevalence and characteristics of AFFs in Lebanon, which is consistent with the numbers reported in the literature (0.32%-5%). A larger prospective study that includes hospitals across the nation is needed to gain a more comprehensive view of the prevalence of AFFs in the Lebanese population.

Taking care of inpatients with fragility hip fractures: the hip-padua osteosarcopenia (Hip-POS) fracture liaison service model.

PURPOSE: Osteoporotic fragility fractures (FF), particularly those affecting the hip, represent a major clinical and socio-economic concern. These fractures can lead to various adverse outcomes, which may be exacerbated by the presence of sarcopenia, especially among older and frail patients. Early identification of patients with FF is crucial for implementing effective diagnostic and therapeutic strategies to prevent subsequent fractures and their associated consequences. METHODS: The Hip-POS program, implemented at Azienda Ospedale-Università Padova, is a Fracture Liaison Service (FLS) program to evaluate patients aged > 50 years old admitted with fragility hip fractures, involving an interdisciplinary team. After the identification of patients with hip fractures in the Emergency Department, a comprehensive evaluation is conducted to identify risk factors for further fractures, and to assess the main domains of multidimensional geriatric assessment, including muscle status. Patients are then prescribed with anti-fracture therapy, finally undergoing periodic follow-up visits. RESULTS: During the first five months, a total of 250 patients were evaluated (70.4% women, median age 85 years). Following assessment by the Hip-POS team, compared to pre-hospitalization, the proportion of patients not receiving antifracture therapy decreased significantly from 60 to 21%. The prescription rates of vitamin D and calcium increased markedly from 29.6% to 81%. CONCLUSIONS: We introduced the Hip-POS program for the care of older adults with hip fractures. We aspire that our model will represent a promising approach to enhancing post-fracture care by addressing the multifactorial nature of osteoporosis and its consequences, bridging the gap in secondary fracture prevention, and improving patient outcomes.

Unusual Pattern of Osteochondral Marginal Impaction in Acetabular Fractures: A Report of Two Cases.

Acetabular fractures could be accompanied by articular impaction injuries, affecting the outcomes if missed or treated less than optimally. Marginal impaction detected either in preoperative or intraoperatively imaging studies should be anatomically reduced using the femoral head as a template and augmenting the defect with bone graft if needed. The impacted segment articular surface looks enface during surgery, which is the classic description of such injuries. In the present report, we describe an unusual pattern of marginal impaction injuries appearance in two patients, in which the impacted fragment articular surface is facing toward the joint cavity, which is the reverse of the classic description, alluding to the probable mechanism of its occurrence, the technique for reduction, and the consequences of missing such injuries. Marginal impaction injuries should be diagnosed and treated correctly to preserve joint congruency; however, the surgeon should be aware of the possibility of an unusual pattern of marginal impaction in which the fragment could be reversed, and keeping this possibility in mind would make its diagnosis and management easier.

Complication Rates in Intertrochanteric Fractures: A Database Analysis Comparing Sliding Hip Screw and Cephalomedullary Nail.

Objectives: In the treatment of closed intertrochanteric fractures, the two most common treatment options are intramedullary medullary nail (IMN) and dynamic hip screw (DHS), yet the best treatment method remains controversial. The purpose of this study is to determine the difference in mortality and morbidity between IMN and DHS. Secondarily, this study determines which pre-operative risk factors affect rates of morbidity and mortality. Methods: American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) 2006-2016 database was used to search for patients with a closed intertrochanteric hip fracture. Bivariate analysis was performed using Pearson's Chi Square test to determine pre-operative risk factors associated with complications in fixation with IMN and DHS. Significant variables in this analysis, as well as demographic data, were analyzed via binary logistic regression. The results were recorded as odds ratio (OR) and significant differences were based on a P<0.05. Results: After adjusting for demographics and clinical covariates, patients who underwent fixation with IMN had higher 30-day mortality, reintubation, UTI, bleeding, prolonged length of stay, and non-home discharged destination rates compared to DHS. Mortality risk was increased by ascites, disseminated cancer, impaired functional status, history of congestive heart failure, and hypoalbuminemia. Bleeding risk was increased by previous percutaneous coronary (PCI) and transfusions and was decreased by impaired functional status. Myocardial infarction risk was increased by female gender. Conclusion: Our study found that IMN fixation increased risk of mortality, UTI, reintubation, bleeding, prolonged length of stay, and a non-home discharge destination compared to DHS. This study also identified patient risk factors associated with several postoperative complications. These data may better inform orthopaedic surgeons treating closed intertrochanteric fractures.

Utilization of the pericapsular nerve group block in preoperative rehabilitation of patients with femoral neck fractures: a case series.

Background: Elderly patients with femoral neck fractures, particularly those with severe comorbidities or living in regions with limited medical resources, may experience delays in surgical treatment. Although the benefits of preoperative rehabilitation (prehabilitation) in hip arthroplasty have been reported, pain management remains a challenge. The pericapsular nerve group (PENG) block, known for its exceptional analgesic effect and motor function preservation, may be a promising intervention during prehabilitation in these patients. Case: We enrolled ten patients with Garden classification 3-4 femoral neck fractures scheduled for hip arthroplasty. After receiving a PENG block with 20 ml of 0.375% ropivacaine, all patients underwent initial prehabilitation sessions comprising 9 mobility levels, ranging from bed-sitting to walking. One patient was excluded due to experiencing high blood pressure during prehabilitation. Six of the nine remaining patients (66.7%) were successfully transferred from bed to wheelchair. Conclusions: The PENG block enhanced prehabilitation for patients with femoral neck fractures undergoing hip arthroplasty.

Allied health assistant management of people with hip fracture is feasible and may improve patient adherence to hip fracture mobilisation guidelines: a feasibility randomised controlled trial.

OBJECTIVES: Determine the feasibility of allied health assistant (AHA) management of people with hip fracture an acute hospital. DESIGN: Assessor-blind, parallel, feasibility randomised controlled trial with qualitative component. SETTING: Acute orthopaedic ward. PARTICIPANTS: People with surgically-managed hip fracture, who walked independently pre-fracture and had no cognitive impairment. INTERVENTIONS: Rehabilitation from an AHA, under the supervision of a physiotherapist, compared with rehabilitation from a physiotherapist. MAIN OUTCOME MEASURES: Feasibility was evaluated according to focus areas of demand, acceptability, practicality and implementation. Secondary outcomes included estimates of effect of adherence to hip fracture mobilisation guidelines, discharge destination, 30-day readmission, functional activity, and length of stay. RESULTS: Fifty people were allocated to receive rehabilitation from an AHA (n = 25) or physiotherapist (n = 25). AHA rehabilitation had high demand with 60% of eligible participants recruited. Satisfaction with AHA rehabilitation was comparable with physiotherapy rehabilitation (acceptability). The AHA group received an average of 11 min (95% CI 4 to 19) more therapy per day than the physiotherapy group (implementation). The AHA group may have had lower cost of acute care (MD -$3 808 95% CI -7 651 to 35) and adverse events were comparable between groups (practicality). The AHA group may have been 22% (HR 1.22, 95% CI 0.92 to 1.61) more likely to walk on any day and may have had a shorter length of stay (MD -0.8 days, 95% CI -2.3 to 0.7). CONCLUSIONS: AHA management of patients with hip fracture was feasible and may improve adherence to mobilisation guidelines and reduce cost of care and length of stay.

Development and validation of machine learning models to predict perioperative transfusion risk for hip fractures in the elderly.

BACKGROUND: Patients with hip fractures frequently need to receive perioperative transfusions of concentrated red blood cells due to preoperative anemia or surgical blood loss. However, the use of perioperative blood products increases the risk of adverse events, and the shortage of blood products is prompting us to minimize blood transfusion. Our study aimed to construct a machine learning algorithm predictive model to identify patients at high risk for perioperative transfusion early in hospital admission and to manage their patient blood to reduce transfusion requirements. METHODS: This study collected patients hospitalized for hip fractures at a university hospital from May 2016 to November 2022. All patients included in the analysis were randomly divided into a training set and validation set according to 70:30. Eight machine learning algorithms, CART, GBM, KNN, LR, NNet, RF, SVM, and XGBoost, were used to construct the prediction models. The models were evaluated for discrimination, calibration, and clinical utility, and the best prediction model was selected. RESULTS: A total of 805 patients were included in the study, of whom 306 received transfusions during the perioperative period. We screened eight features used to construct the prediction model: age, fracture time, fracture type, hemoglobin, albumin, creatinine, calcium ion, and activated partial thromboplastin time. After evaluating and comparing the performance of each of the eight models, the model constructed by the XGBoost algorithm had the best performance, with MCC values of 0.828 and 0.939 in the training and validation sets, respectively. In addition, it had good calibration and clinical utility in both the training and validation sets. CONCLUSION: The model constructed by the XGBoost algorithm has the best performance, using this model to identify patients at high risk for transfusion early in their admission and promptly incorporating them into a patient blood management plan can help reduce the risk of transfusion.
