RESUMO
A validation of the GeRi-Score on 120-day mortality, the impact of a pre-operative visit by a geriatrician, and timing of surgery on the outcome was conducted. The score has predictive value for 120-day mortality. No advantage was found for surgery within 24 h or a preoperative geriatric visit. PURPOSE: Numerous tools predict mortality among patients with hip fractures, but they include many variables, require time-consuming assessment, and are difficult to calculate. The GeRi-Score provides a quick method of pre-operative assessment. The aim of this study is to validate the score in the 120-day follow-up and determine the impact of a pre-operative visit by a geriatrician and timing of surgery on the patient outcome. METHODS: A retrospective analysis of the AltersTraumaRegister DGU® from 2017 to 2021 was conducted, including all proximal femur fractures. The patients were divided into low-, moderate-, and high-risk groups based on the GeRi-Score. Mortality was analyzed using logistic regression. To determine the influence of the time to surgery and the preoperative visit by a geriatrician, matching was performed using the exact GeRi-Score, preoperative walking ability, type of fracture, and the time to surgery. RESULTS: The study included 38,570 patients, divided into 12,673 low-risk, 18,338 moderate-risk, and 7,559 high-risk patients. The moderate-risk group had three times the mortality risk of the low-risk group (OR 3.19 (95% CI 2.68-3.79; p<0.001)), while the high-risk group had almost eight times the mortality risk than the low-risk group (OR 7.82 (95% CI 6.51-9.93; p<0.001)). No advantage was found for surgery within the first 24 h across all groups. There was a correlation of a preoperative geriatric visit and mortality showing an increase in the moderate and high-risk group on in-house mortality. CONCLUSIONS: The GeRi-Score has predictive value for 120-day mortality. No advantage was found for surgery within 24 h. The analysis did not demonstrate a benefit of the preoperative geriatric visit, but more data are needed.
RESUMO
Background and Objectives: This study aimed to determine the relationship between non-simultaneous contralateral hip fractures, urban and rural differences, fracture localization, time between fractures, physiotherapy applications, comorbidity, and the second fracture outcomes. Materials and Methods: We retrospectively analyzed 107 patients aged 65 and older with proximal femur fractures (PFFs) who underwent surgery at Düzce University Medical Faculty between January 2010 and December 2022. High-energy fractures, pathological fractures, and patients with a history of old fractures were excluded. Results: The study included 66 females (61.7%) and 41 males (38.3%), with a mean age of 83.76 years. The mean interval between two fractures was 28.3 months. There was no statistical difference between the localization of the first and second fractures (p = 0.107). However, there was a significant difference in the first PFF localizations of patients living in rural areas (p = 0.023). Patients with heart failure, respiratory failure, osteoporosis, and cognitive impairment had shorter intervals between fractures (p < 0.001). Conclusions: This study shows that age, female gender, place of residence, comorbid diseases, and whether physical therapy is received after the first fracture are significant risk factors for a second hip fracture in patients over 65 years of age.

Introduction: Fracture of the proximal femur is common in elderly patients, in fact threatening their lives. Age-related sarcopenia may be involved in the imbalance resulting in the injury. Handy and readily accessible biochemical tests would be useful to assess the musculoskeletal system condition in daily practice. The aim of the study was to determine whether there is any relation between muscle decay and fracture of the proximal femur and to assess bone quality in elderly patients. Material and methods: In the study 22 patients who represented the treatment group were hospitalized due to proximal femur fracture. Eighteen patients from the control group with no fracture in their history were admitted to the Internal Medicine Department. Anyone treated for osteoporosis, immune disease affecting protein balance, neoplasm, mental illness, heart failure, or myocardial infarction was excluded from the study. In every case a blood sample from an elbow vein was drawn, collected in EDTA-K2 tubes, and then centrifuged to separate plasma from the whole blood. Subsequently, the concentrations of C-terminal cross-linked telopeptide of type I collagen (CTX-I), sex hormone binding globulin (SHBG) and creatine kinase (CK) in plasma were determined using commercial enzyme-linked immunosorbent assays. Results: The CK plasma concentration differed between the patient groups (p = 0.011). The SHBG plasma concentration was significantly higher in the treatment group (p = 0.006), whereas a slight difference in CTX-I plasma concentration between the groups was found (p = 0.038). No significant correlations between plasma CK, SHBG or CTX-I were found (p > 0.05). Conclusions: Creatine kinase is actually not an appropriate marker for the clinical assessment of muscle tissue quality in patients with or at risk of proximal femur fracture. Analyzing the quality of bone tissue, we can conclude it was poorer in patients with proximal femur fracture than in the control group.
RESUMO
PURPOSE: The aim of our study was to analyze the clinical and radiological outcomes of conversion total hip arthroplasty (THA) for failed fixation of proximal femur fractures with monoblock grit-blasted titanium reconstruction stem (Wagner self-locking stem, Zimmer). PATIENTS AND METHODS: Thirty-nine patients were included in this retrospective analysis undergoing conversion THA for failed cephalomedullary nail or dynamic hip screw fixation for intertrochanteric fractures from January 2017 to January 2022. The clinical evaluation was done using Harris hip score. The radiological outcomes measured were subsidence, level of osteointegration, stem-canal fill ratio and heterotopic bone formation. The complications were noted postoperatively and during the follow-up. RESULTS: The mean follow-up at the end of the study was 27.8 months (range, 14-72 months). There was a significant improvement in the Harris hip score over serial follow-ups (p < 0.001), but after 2 years, there was no statistically significant difference (p = 0.46). According to Engh's criteria, stable ingrowth was noted in 35 stems, fibrous stable ingrowth was noted in 4 stems and no patients had progressive subsidence and unstable stem. The mean stem-canal fill percentages were 91.8 ± 5.4% at the mid-stem and 80.3 ± 11.5% at the stem tip. Heterotopic ossification Brooker grade 2 was noted in 8 patients, and no patients had grade 3 or 4 heterotopic ossification. There were 7 (17.9%) intraoperative periprosthetic fractures, and greater trochanteric avulsion was noted in 2 patients in the follow-up. CONCLUSION: Conversion THA using monoblock tapered distal loading stems bypasses the calcar deficiency and gives stable fixation in failed fixation of intertrochanteric fractures. It gives good radiological outcome and significant improvement in the clinical outcomes compared to the preoperative disability. However, caution should be noted for risk of intraoperative periprosthetic fractures in this subgroup of patients.

This study developed an easy-to-use mortality prediction tool, which showed an acceptable discrimination and no significant lack of fit. The GeRi-Score was able to predict mortality and could distinguish between mild, moderate and high risk groups. Therefore, the GeRi-Score might have the potential to distribute the intensity of medical care. PURPOSE: Several mortality-predicting tools for hip fracture patients are available, but all consist of a high number of variables, require a time-consuming evaluation and/or are difficult to calculate. The aim of this study was to develop and validate an easy-to-use score, which depends mostly on routine data. METHODS: Patients from the Registry for Geriatric Trauma were divided into a development and a validation group. Logistic regression models were used to build a model for in-house mortality and to obtain a score. Candidate models were compared using Akaike information criteria (AIC) and likelihood ratio tests. The quality of the model was tested using the area under the curve (AUC) and the Hosmer-Lemeshow test. RESULTS: 38,570 patients were included, almost equal distributed to the development and to the validation dataset. The AUC was 0.727 (95% CI 0.711 - 0.742) for the final model, AIC resulted in a significant reduction in deviance compared to the basic model, and the Hosmer-Lemeshow test showed no significant lack of fit (p = 0.07). The GeRi-Score predicted an in-house mortality of 5.3% vs. 5.3% observed mortality in the development dataset and 5.4% vs. 5.7% in the validation dataset. The GeRi-Score was able to distinguish between mild, moderate and high risk groups. CONCLUSIONS: The GeRi-Score is an easy-to-use mortality-predicting tool with an acceptable discrimination and no significant lack of fit. The GeRi-Score might have the potential to distribute the intensity of perioperative medical care in hip fracture surgery and can be used in quality management programs as benchmark tool.

PURPOSE: The economic cost linked to the increasing number of proximal femur fracture and their postoperative care is immense. Mortality rates are high. As early surgery is propagated to lower mortality and reduce complication rates, a 24-h target for surgery is requested. It was our aim to determine the cut-off for the time to surgery from admission and therefore establish a threshold at which the in-house mortality rate changes. METHODS: A retrospective single-center cohort study was conducted including 1796 patients with an average age of 82.03 years treated operatively for a proximal femoral fracture between January 2016 and June 2020. A single treatment protocol was performed based on the type of anticoagulant, surgery, and renal function. Patient data, surgical procedure, time to surgery, complications, and mortality were assessed. RESULTS: In-house mortality rate was 3.95%, and the overall complication rate was 22.7%. A prolonged length of hospital stay was linked to patient age and occurrence of complications. Mortality is influenced by age, number of comorbidities BMI, and postoperative complications of which the most relevant is pneumonia. The mean time to surgery for the entire cohort was 26.4 h. The investigation showed no significant difference in mortality rate among the two groups treated within 24 h and 24 to 48 h while comparing all patients treated within 48 h and after 48 h revealed a significant difference in mortality. CONCLUSIONS: Age and number of comorbidities significantly influence mortality rates. Time to surgery is not the main factor influencing outcome after proximal femur fractures, and mortality rates do not differ for surgery up to 48 h after admission. Our data suggest that a 24-h target is not necessary, and the first 48 h may be used for optimizing preoperative patient status if necessary.

BACKGROUND: Impact of concomitant fractures on patients sustaining a proximal femur fracture remains unclear. Rising numbers and patient need for rehab is an important issue. The objective of our study was to investigate the impact of concomitant fractures, including all types of fractures, when treated operatively, for proximal femur fractures on the length of hospital stay, in-house mortality and complication rate. METHODS: Observational retrospective cohort single-center study including 85 of 1933 patients (4.4%) with a mean age of 80.5 years, who were operatively treated for a proximal femoral and a concomitant fracture between January 2016 and June 2020. A matched pair analysis based on age, sex, fracture type and anticoagulants was performed. Patient data, length of hospital stay, complications and mortality were evaluated. RESULTS: The most common fractures were osteoporosis-associated fractures of the distal forearm (n = 34) and the proximal humerus (n = 36). The group of concomitant fractures showed a higher CCI than the control group (5.87 vs. 5.7 points; p < 0.67). Patients with a concurrent fracture had a longer hospital stay than patients with an isolated hip fracture (15.68 vs. 13.72 days; p < 0.056). Complications occurred more often in the group treated only for the hip fracture (11.8%, N = 20), whilst only 7.1% of complications were recorded for concomitant fractures (p < 0.084). The in-house mortality rate was 2.4% and there was no difference between patients with or without a concomitant fracture. CONCLUSIONS: A concomitant fracture to a hip fracture increases the length of hospital stay significantly but does not increase the complication rate or the in-house mortality. This might be due to the early mobilization, which is possible after early operative treatment of both fractures.

BACKGROUND: Currently, there is no consensus on the most appropriate technique for obtaining lateral hip radiographs after cephalomedullary nail (CMN) surgery. The aim of this study was to investigate the distribution of two commonly used postoperative lateral hip radiographic methods (classic lateral view and modified lateral view) and try to find out which one is better suited for this situation. METHODS: A retrospective analysis was conducted on 146 patients who underwent surgical fixation for extracapsular hip fractures between January 2018 and June 2022. The main outcome measured was the angle between the straight part of the CMN and the lag screw/blade on hip lateral X-rays (CMNA). The lateral hip radiographs were categorized into two groups based on different lateral hip radiographic methods. CMNA, patient age, gender, fracture classification based on the 2018 AO classification, nail length (short/long), surgical side (left/right), height, weight, BMI, preoperative waiting time, postoperative imaging interval were collected and compared between the two groups. RESULTS: The distribution trend of CMNA significantly differs between two types of hip joint lateral radiographic methods. Specifically, the classic lateral method exhibits a significantly bimodal and skewed distribution with a median (p25, p75) of -21.6° (-31.2°, -8°), whereas the modified lateral method presents a normal distribution with a mean ± SD of +7.57° ± 14.4°. The difference in the Mean Rank between the classic (47.10) and the modified (102.96) lateral methods is statistically significant (P < 0.001). CONCLUSIONS: The CMNA method is an excellent tool for studying the lateral distribution.We recommend using the modified lateral view as the preferred option for obtaining lateral hip radiographs after CMN surgery due to its superior distribution of CMNA and greater patient-friendliness.

BACKGROUND: Early fixation and rehabilitation is the gold standard treatment for intertrochanteric femur fractures. Cement augmentation through perforated head elements has been developed to avoid postoperative complications such as cut-out or cut-through. The purpose of this study was to compare two head elements in terms of cement distribution using computed tomography (CT) and to examine their initial fixation and clinical outcomes. METHODS: Elderly patients who had intertrochanteric fractures were treated with a trochanteric fixation nail advanced (TFNA) helical blade (Blade group) or a TFNA lag screw (Screw group). In both groups, 4.2 mL of cement was injected under an image intensifier (1.8 mL of cement was directed cranially and 0.8 mL each caudally, anteriorly, and posteriorly). Patient demographics and clinical outcome were investigated post-operatively. Cement distribution from the center of the head element was evaluated with CT. Maximum penetration depth (MPD) were measured in the coronal and sagittal planes. On each axial plane, the cross-sectional areas in the cranial, caudal, anterior and posterior directions were calculated. The sum of cross-sectional areas (successive 36 slices) was defined as the volume of the head element. RESULTS: The Blade group included 14 patients, and the Screw group included 15 patients. In the Blade group, MPD in the anterior and caudal direction was significantly greater than that in the posterior direction (p < 0.01). In the Screw group, volume in the cranial and posterior direction was significantly greater than that in the Blade group (p = 0.03). Subsequently, the total volume in the Screw group was significantly larger than that in the Blade group (p < 0.01). No significant correlation was detected between bone mineral density, T score, young adult mean, and total cement volume. Change in radiographic parameters and clinical outcome such as Parker score and visual analog scale were similar in both groups. No patients suffered from cut-out / cut through or non-union. CONCLUSIONS: The position of cement distribution through the lag screw is different from that through the helical blade, and the total volume of the head element is significantly larger in the lag screw. Both groups had similarly effective results in terms of mechanical stability after surgery, postoperative pain and early phase of rehabilitation.

BACKGROUND: The femoral neck system (FNS) is commonly used for internal fixation of femoral neck fractures and has shown promising results. However, we have observed cases of peri-implant subtrochanteric femur fractures associated with the use of FNS at our institution. This case series aims to investigate four cases of peri-implant subtrochanteric fractures in patients treated with the FNS implant for femoral neck fractures. CASE PRESENTATION: We reviewed 35 patients who underwent treatment with FNS for femoral neck fractures between January 2017 and December 2021 at our level 1 trauma institution. Among these patients, four cases of peri-implant subtrochanteric femur fractures were identified. In contrast, no such fractures occurred in patients treated with cannulated screws or dynamic hip screws (DHS). Interestingly, all four cases of peri-implant fractures were seen in patients with incomplete nondisplaced femoral neck fractures. Only one case involved an identifiable technical error. CONCLUSIONS: This case series sheds light on peri-implant subtrochanteric femur fractures as a previously unreported complication associated with the use of FNS for femoral neck fractures. These fractures were observed exclusively in patients with incomplete nondisplaced fractures who received FNS fixation. No similar complications were observed in patients treated with other types of fixation. This finding suggests the need for caution and further investigation when considering FNS as a treatment option for this specific fracture pattern. The identification of peri-implant subtrochanteric femur fractures as a potential complication of FNS usage in incomplete nondisplaced femoral neck fractures raises important considerations for clinical decision-making and patient management in orthopedic trauma.

OBJECTIVE: The purpose of this study is to develop and validate a deep convolutional neural network (DCNN) model to automatically identify the manufacturer and model of hip internal fixation devices from anteroposterior (AP) radiographs. MATERIALS AND METHODS: In this retrospective study, 1721 hip AP radiographs, including six internal fixation devices from 1012 patients, were collected from an orthopedic center between June 2014 and June 2022 to establish a classification network. The images were divided into training set (1106 images), validation set (272 images), and test set (343 images). The model efficacy is evaluated by using the data on the test set. The overall TOP-1 accuracy, and the precision, sensitivity, specificity, and F1 score of each model are calculated, and receiver operating characteristic (ROC) curves are plotted to evaluate the model performance. Gradient-weighted class activation mapping (Grad-CAM) images are used to determine the image features that are most important for DCNN decisions. RESULTS: A total of 1378 (80%) images were used for model development, and model efficacy was validated on a test set with 343 (20%) images. The overall TOP-1 accuracy was 98.5%. The area under the receiver operating characteristic curve (AUC) values for each internal fixation model were 1.000, 1.000, 0.980, 1.000, 0.999, and 1.000, respectively. Gradient-weighted class activation mapping showed the unique design of the internal fixation device. CONCLUSION: We developed a deep convolutional neural network model that can identify the manufacturer and model of hip internal fixation devices from the hip AP radiographs.

BACKGROUND: The treatment of Vancouver B periprosthetic proximal femur fractures (PPFFs) is complex due to the overlap between arthroplasty and orthopedic trauma techniques. Our purpose was to assess the effects of fracture type, treatment difference, and surgeon training on the risk of reoperation in Vancouver B PPFF. METHODS: A collaborative research consortium of 11 centers retrospectively reviewed PPFFs from 2014 to 2019 to determine the effects of variations in surgeon expertise, fracture type, and treatment on surgical reoperation. Surgeons were classified as per fellowship training, fractures using the Vancouver classification, and treatment as open reduction internal fixation (ORIF) or revision total hip arthroplasty with or without ORIF. Regression analyses were performed with reoperation as the primary outcome. RESULTS: Fracture type (Vancouver B3 versus B1: odds ratio [OR]: 5.70) was an independent risk factor for reoperation. No differences were found in reoperation rates with treatment (ORIF versus revision: OR 0.92, P = .883). Treatment by a nonarthroplasty-trained surgeon versus an arthroplasty specialist led to higher odds of reoperation in all Vancouver B fracture (OR: 2.87, P = .023); however, no significant differences were seen in the Vancouver B2 group alone (OR: 2.61, P = .139). Age was a significant risk factor for reoperation in all Vancouver B fractures (OR: 0.97, P = .004) and in the B2 fractures alone (OR: 0.96, P = .007). CONCLUSION: Our study suggests that age and fracture type affect reoperation rates. Treatment type did not affect reoperation rates and the effect of surgeon training is unclear.

INTRODUCTION: The cumulated ambulation score (CAS) has been developed as an index for evaluating mobility in the early postoperative period. This study aimed to estimate the association between CAS and independent ambulation after surgery for proximal femur fractures. MATERIALS AND METHODS: This retrospective cohort study included 223 elderly patients who underwent surgery for proximal femur fractures and had independent ambulation before the injury. Multivariable logistic regression analyses with cognitive impairment, pre-injury Barthel index, and CAS as the test variables were used to predict independent ambulation at 2 weeks (model 1) and 3 months (model 2) postoperatively. We established scoring systems based on the modeling results. RESULTS: The number of patients with independent ambulation at 2 weeks and 3 months postoperatively was 115 and 169, respectively. Univariate analysis showed that the CAS was significantly associated with independent ambulation at 2 weeks and 3 months postoperatively. Multivariable analysis showed that models 1 and 2 had good predictive accuracies, with areas under the receiver-operating characteristic curve of 0.855 and 0.868, respectively. Among the explanatory variables, only the CAS in model 2 was not significantly associated with the postoperative ambulatory ability. Scoring systems for both models 1 and 2 also had good predictive accuracies, with cut-off scores of 3.5 for model 1 and 9.5 for model 2. CONCLUSIONS: The CAS predicted independent ambulation at 2 weeks postoperatively; however, this relationship was limited at 3 months postoperatively. Therefore, the CAS may help estimate independent ambulation at discharge from an acute-care hospital.

Background and Objectives: Patients with occult hip fractures are a difficult subgroup to treat. MRI is the gold standard for diagnosing occult proximal femur fractures but is costly and may not be readily available in an emergency setting. The purpose of this study was to determine whether changes in the proximal femur geometry can predict the likelihood of an occult hip fracture in patients presenting with hip pain following a ground-level fall. Material and Methods: Patients admitted to the hospital with a clinical suspicion of a hip fracture but initial negative radiographs over a seven-year period were included. All patients were additionally investigated with an MRI scan, and retrospectively, six radiologic parameters were obtained on plain radiographs: The cortical thickness index (CTI), the canal to calcar ratio (CCR), the canal flare index (CFI), the morphological cortical index (MCI), the canal bone ratio (CBR) and the canal bone aria ratio (CBAR). Subsequently the result of the plain radiographic indices of the patients with a negative MRI (Group A, no occult fracture) were compared to those with a positive MRI (Group B, occult fracture). Results: A total of 78 patients (59 female, 19 male) could be included in the study. The mean age was 82 years. The univariate analyses revealed a poor predictive ability of all radiological parameters with AUC values ranging from 0.515 (CBR) to 0.626 (CTI), whereas a multivariate prognostic model demonstrated improved prognosis (AUC = 0.761) for the CTI (p = 0.024), CBAR (p = 0.074) and CRR (p = 0.081) as the most promising predictive radiological parameters. Conclusions: Single radiologic indices obtained from conventional X-rays of the proximal femur have a weak predictive value in detecting occult fractures of the hip and cannot be used as clinical decision-making factors.

BACKGROUND: The World Health Organization classified Covid-19 as a pandemic during the first months of 2020 as lockdown measures were implemented globally to mitigate the increasing incidence of Covid-19-related morbidity and mortality. The purpose of this study was to evaluate the effect of national lockdown measures on proximal femur fracture epidemiology. Our hypothesis was that due to the prolonged period of stay-at-home orders, we would observe a decrease in the incidence of proximal femur fractures during the years 2020-21. METHODS: A retrospective case-control study of 2784 hip fractures admitted to the emergency department at one hospital between January 1, 2010, and March 31, 2021, was conducted. Cases were stratified weekly, and an analysis was conducted comparing cases occurring during government-imposed lockdown periods of 2020-21 to corresponding periods during 2010-2019. Furthermore, the trend of cases throughout the year of 2020 was observed. RESULTS: Of all proximal femur fracture cases included, 2522 occurred between 2010-2019 and 261 during the Covid-19 period. There was no significant difference in age (81.95 vs. 82.09; P = 0.78) or gender (P = 0.12). There was a total decrease of 21.64% in proximal femur fracture per week during the entirety of the Covid-19 pandemic period compared to the previous years (3.64 ± 1.99 vs. 4.76 ± 0.83; P = 0.001). During all three lockdown periods, there was a significant decrease in proximal femur fracture cases per week (3.55 ± 2.60 vs. 4.87 ± 0.95; P = 0.04), and the most pronounced decrease occurred during the third lockdown period (2.89 ± 1.96 vs. 5.23 ± 1.18; P = 0.01). CONCLUSION: We observed a total decrease in the number of proximal femur fractures occurring during the Covid-19 era compared to previous years and specifically a decrease of cases occurring during the government-imposed lockdown periods. The decrease in cases was more pronounced during the second and third lockdown periods.

PURPOSE: The prevalence of proximal femur fractures is increasing with rising population age. Patients are presenting with more comorbidities. Anticoagulants create a challenge for the necessary early surgical procedure (osteosynthesis or arthroplasty). Our aim was to investigate the influence of anticoagulants on in-house mortality after surgical treatment of proximal femoral fractures. METHODS: A retrospective single-centre study was conducted including 1933 patients with an average age of 79.8 years treated operatively for a proximal femoral fracture between January 2016 and June 2020. One treatment protocol was performed based on type of anticoagulant, surgery, and renal function. Patient data, surgical procedure, time to surgery, complications and mortality were assessed. RESULTS: On average, patients with anticoagulants had a delay to surgery of 41.37 hours vs 22.1 hours for patients without (p < 0.000). Anticoagulants were associated with the occurrence of complications. The total complication rate was 22.4%. Patients with complications showed a prolonged time to surgery in comparison to those without (28.9 h vs 24.9 h; p < 0.00). In-house mortality rate was 4% and twice as high for patients on anticoagulants (7.7%; p < 0.00). Whilst there was no significant difference in the mortality rate between surgery within 24 and 48 hours (2.9% vs. 3.8%; p < 0.535), there was a significant increase in mortality of patients waiting more than 48 hours (9.8%; p < 0.001). CONCLUSIONS: Pre-existing anticoagulant therapy in patients with proximal femur fractures is associated with a higher mortality rate, risk of complications and prolonged hospital stay. Further influential factors are age, gender, BMI and time to surgery.

BACKGROUND: Cut-out failure following proximal femoral fracture fixation is a compromising complication warranting surgical treatment. We describe 24 patients with cut-out failure after cephalomedullary nail fixation managed with salvage hip replacement. METHODS: Twenty-four consecutive patients who had sustained a proximal femoral fracture from December 2009 to December 2019, were managed with cephalomedullary nail fixation and experienced a cut-out failure were reviewed retrospectively. Data on demographics, comorbidities, injury characteristics, treatment, and post-operative course were analysed. RESULTS: Among 2802 proximal femoral fractures assessed, 28 fixations failed due to cut-out, with 24/28 patients subsequently undergoing salvage hip replacement. Intertrochanteric fractures (66.7%) managed with short nails predominated (79.2%). The median tip-to-apex distance (TAD) was 19 mm, but only two fractures had a good quality of reduction. Inverse correlations were identified between patient age and the time from fixation to cut-out (r = - 0.57; p = 0.02), and between the time of nailing to failure among patients with a greater TAD (r = - 0.43; p = 0.04). Most patients were managed via cemented hemiarthroplasty (66.7%). Surgical time was longer for total hip replacements (175.4 vs. 136.8 min; p < 0.01), but no bleeding or blood transfusion requirement differences were found. Two patients had orthopaedic complications, and three patients died within the first follow-up year. CONCLUSION: In our series, 1% of the proximal femoral fractures managed with a cephalomedullary nail failed due to cut-out. Salvage hip replacement appeared to be a relatively safe and reliable procedure for managing this challenging complication in patients who typically are elderly and physically frail.

Background: Osteoporotic fractures are associated with a loss of quality of life, but only few patients receive an appropriate therapy. Therefore, the present study aims to investigate the awareness of musculoskeletal patients to participate in osteoporosis assessment and to evaluate whether there are significant differences between acute care patients treated for major fractures of the hip compared to elective patients treated for hip joint replacement.; Methods: From May 2015 to December 2016 patients who were undergoing surgical treatment for proximal femur fracture or total hip replacement due to osteoarthritis and were at risk for an underlying osteoporosis (female > 60 and male > 70 years) were included in the study and asked to complete a questionnaire assessing the awareness for an underlying osteoporosis. ASA Score, FRAX Score, and demographic information have also been examined. Results: In total 268 patients (female = 194 (72.0%)/male = 74 (28%)), mean age 77.7 years (±7.7) undergoing hip surgery were included. Of these, 118 were treated for fracture-related etiology and 150 underwent total hip arthroplasty in an elective care setting. Patients were interviewed about their need for osteoporosis examination during hospitalization. Overall, 76 of 150 patients receiving elective care (50.7%) considered that an examination was necessary, whereas in proximal femur fracture patients the awareness was lower, and the disease osteoporosis was assessed as threatening by significantly fewer newly fractured patients. By comparison, patients undergoing trauma surgery had a considerably greater risk of developing another osteoporotic fracture than patients undergoing elective surgery determined by the FRAX® Score (p ≤ 0.001).; Conclusions: The patients' motivation to endure additional osteoporosis diagnostic testing is notoriously low and needs to be increased. Patients who underwent acute care surgery for a fragility proximal femur fracture, although acutely affected by the potential consequences of underlying osteoporosis, showed lower awareness than the elective comparison population that was also on average 6.1 years younger. Although elective patients were younger and at a lower risk, they seemed to be much more willing to undergo further osteoporosis assessment. In order to better identify and care for patients at risk, interventions such as effective screening, early initiation of osteoporosis therapy in the inpatient setting and a fracture liaison service are important measures.

The COVID-19 pandemic has significantly reduced the number of orthopedic surgeries world- wide. The main reason for this was an introduction of numerous restrictions in the field of mobility, which resulted in reduction of circumstances predisposing to injuries. This had a positive impact on the overall readiness of the health system to fight the pandemic, thanks to saving human and material resources that could be successfully allocated in order to fight a new, previously unknown threat. On the other hand, such aimed administration of the system was not indifferent in terms of care quality directed towards traumatized patients, often requiring immediate measures (risk of infection transmission). This study aims to evaluate in-hospital mortality in patients with COVID-19 operated on proximal femur fractures. An attempt was also made to determine predictors influencing mortality rate among patients operated over the analyzed period.
