A Comparative Study of the Effect of Pericapsular Nerve Block (PENG) and Ultrasound-guided Fascia Iliaca Blocks on Postoperative Pain of Intertrochanteric Fractures

Background: Previous anesthesia blocks often failed to provide complete pain relief and were associated with weakness in the lower limbs, which hindered the essential mobility of patients undergoing hip surgery. Recently, the pericapsular nerve group block (PENG) has emerged as a promising alternative for managing postoperative pain following hip fracture surgery. Objectives: This study aimed to compare pain reduction between the pericapsular nerve group block (PENG) and the fascia iliaca compartment block (FICB) in patients who underwent intertrochanteric hip surgery. Methods: This randomized, double-blind clinical trial included 41 patients who were randomly assigned to either the pericapsular block group (PENG) or the ultrasound-guided (FICB). The primary outcome was pain relief, assessed using the postoperative Visual Analog Scale (VAS) score. Secondary outcomes included the dose of morphine consumed, the time of first morphine request, patient satisfaction with analgesia, and complications. Results: There was no significant difference between the PENG and FICB groups in terms of pain scores at any of the studied intervals (P-value > 0.05). The dose of morphine consumed and the time to the first morphine request were similar for both methods, with no significant difference (P-value > 0.05). The complication rates were 15% for the PENG group and 8.3% for the FICB group, with no significant difference observed (P-value > 0.05). Conclusions: Both pericapsular and fascia iliaca blocks effectively reduced postoperative pain in patients undergoing intertrochanteric fracture surgery. Additionally, both methods were well tolerated by patients with no significant complications. However, there was no evidence to suggest that PENG is superior to FICB in terms of pain reduction.

A Comparative Study between Fascia Iliaca Block and Femoral Nerve Block for Postoperative Analgesia after Intertrochanteric Fracture Surgery

Abstract Background Intertrochanteric fracture surgery is a common orthopedic procedure worldwide, pain may be severe, and the patients generally require a significant amount of opioid-based analgesics after such procedures. Peripheral nerve blocks offer effective analgesia and decrease the need for opioids, thereby reducing the complications associated with the use of this class of drug. Pain management regimens following Intertrochanteric fracture surgery include oral analgesics, periarticular injection, peripheral nerve blocks (PNBs), and intravenous patient- controlled analgesia (PCA). Objective To compare the analgesic efficacy and functional recovery of Fascia iliaca block and FNB in patients who have undergone Hip surgery. Methods This prospective randomized clinical trial study was conducted in Ain Shams University hospital after approval of the anesthesia department and the local ethics and research committee over 6 months and after obtaining a written informed consent. Sixty patients underwent Intertrochanteric fracture surgery under spinal anaesthesia regarding postoperative pain and early ambulation were included in the study their ages range between 40 to 75 years old and classified as ASA I and II. The patients were randomly divided using computer generated randomization into two groups 30 patients in each (n = 30). Results The two groups were compared as regard pain control post operatively. Numerical rating scale (NRS) was used to assess pain post operatively and used at regular interval (PACU, After 15min., After 30min., After 45min., After 1 hr., After 1.5 hrs., After 2 hrs., After 4 hrs., After 6 hrs., After 8 hrs., After 10 hrs., After 12 hrs., After 14 hrs., After 16 hrs., After 18 hrs., After 20 hrs., After 22 hrs. and After 24 hrs.). And there is no significant difference between two groups, with p- value (p > 0.05 NS). As regard to total dose of narcotics used in each group, there is no difference in postoperative nalbuphine consumption. The two groups are compared as regard to quadriceps weakness, onset of ambulation and there was a significant difference between two groups. Conclusion Fascia iliaca block is more effective than Femoral Nerve Block in in patient satisfaction for post-operative analgesia and equally effective with femoral nerve block in post-operative ambulation after Intertrochanteric fracture surgery.

One-year mortality risk in older individuals with femoral intertrochanteric fracture: a tertiary center in China

BackgroundThe accelerated growth of older individuals worldwide has increased the number of patients presenting with fragility hip fractures. Having a hip fracture can cause excess mortality, and patients with hip fracture have a higher risk of death than those without hip fracture. Most studies have treated hip fracture as a single, homogeneous condition, but hip fracture includes two major anatomic types: intertrochanteric fracture and femoral neck fracture. Few studies have specifically evaluated 1-year mortality risk in older individuals with femoral intertrochanteric fracture. The aim of this study was to evaluate 1-year mortality and factors associated with mortality in older individuals with femoral intertrochanteric fracture.MethodsA retrospective review was conducted of 563 patients ≥ 65 years old who underwent surgery for femoral intertrochanteric fractures at our institution between January 2010 and August 2018. Patient demographics, comorbidities, and treatment were collected by retrospective chart review. Age, sex, Body Mass Index (BMI), American Society of Anesthesiologists (ASA) classification, Charlson comorbidity index (CCI), Arbeitsgemeinschaft Für Osteosynthesefragen (AO) fracture classification, haemoglobin value at admission, time to surgery, operation time, and intraoperative blood loss were risk factors to be tested. Multivariable logistic regression was used to evaluate associations between variables and death.ResultsAmong the 563 patients, 49 died within 1 year after surgery, and the 1-year mortality rate was 8.7%. Multivariate analysis identified age > 80 years (OR = 4.038, P = 0.011), haemoglobin < 100 g/l (OR = 2.732, P = 0.002), ASA score ≥ 3 (OR = 2.551, P = 0.005), CCI ≥ 3 (OR = 18.412, P = 0.018) and time to surgery > 14 d (OR = 3.907, P = 0.030) as independent risk factors for 1-year mortality. Comorbidities such as myocardial infarction and chronic pulmonary disease were associated with 1-year mortality after adjusting for age > 80 years and time to surgery > 14 days.ConclusionsPatients over 80 years old with haemoglobin < 100 g/l, ASA score ≥ 3, CCI ≥ 3, and multiple comorbidities, especially myocardial infarction and chronic pulmonary disease before surgery, are at a higher risk of 1-year mortality. Doctors should pay more attention to these vulnerable patients, and a surgical delay greater than 14 days should be avoided.

Comparison of Twin Screw Derotation Type Versus Single Helical Blade Type Cephalomedullary Nail in the Management of Unstable Intertrochanteric Fractures.

The intertrochanteric fracture is a frequently occurring fracture, often attributed to osteoporosis in older populations. Recently, there has been a proposal to perform early surgical fixation on elderly patients to facilitate early rehabilitation. This approach has been shown to have a beneficial effect in lowering comorbidities. The study aims to compare the efficacy of the twin screw derotation type cephalomedullary nail with that of the single helical blade type cephalomedullary nail in the management of unstable intertrochanteric fractures. The research sample included patients from the orthopedic outpatient and emergency departments of Adesh Medical College and Hospital,Ambala Cantt, India, who were scheduled for surgery for unstable intertrochanteric femur fractures. The patients were categorized into two groups according to the kind of implant they were given: either a twin screw derotation cephalomedullary nail or a single helical blade cephalomedullary nail. The functional result was evaluated by comparing the modified Harris hip score (HHS). Patients with unstable intertrochanteric fractures, including reverse oblique fractures and fractures with posteromedial comminution, as well as patients who provided consent, were included in this study. Thirteen individuals received treatment with proximal femoral nail antirotation (PFNA2), whereas 19 individuals received treatment with proximal femoral nail (PFN). The mean age in the PFNA2 group was 69.51, whereas the mean age in the PFN group was 70.804. There were three patients in the PFNA2 group and five patients in the PFN group who had a tip apex distance of more than 25 mm. According to the Cleveland index, nine patients in the PFNA2 group and eight patients in the PFN group had an implant location that was not optimum. Four patients in the PFNA2 group and seven patients in the PFN group had a neck shaft angle difference of more than 10° between their undamaged and operated sides. The mean HHS was 74.55 for the PFNA2 group and 69.88 for the PFN group. The PFNA2 group exhibited four problems, whereas the PFN group had five issues. The study found that both implants offer similar functional outcomes, with adherence to specific radiological parameters optimizing results. While both face similar challenges with osteoporosis, there was no notable distinction between them. Notably, the PFNA2 group showed superior outcomes in perioperative morbidity.

Distal Locking of Proximal Femoral Nails in Intertrochanteric Fractures: A Comparison of Taloned and Static Locking Systems

Background: The necessity of distal locking in proximal femoral nails (PFNs) used in intertrochanteric fracture surgery is still controversial. However, the newly designed talon distalfix PFN differs from other PFN systems with its taloned distal locking (TDL) mechanism. Aim: To compare the radiologic and functional results of this newly designed TDL system and the static distal locking (SDL) system. Methods: Between January 2018 and December 2021, 142 patients over the age of 65 who underwent PFN surgery for intertrochanteric fractures in our department and underwent SDL or TDL as the distal locking mechanism were analyzed. The patients were divided into two groups as SDL and TDL according to the type of distal locking applied. Demographic variables and intraoperative data (operative time, intraoperative bleeding amount, and fluoroscopy time) were recorded. Harris hip score and Visual Analog Scale (VAS) score results were recorded to evaluate postoperative functional outcomes. Union time and all postoperative complications were recorded. Results: Of a total of 142 patients with a mean age of 77.51 ± 11.67 years, 79 underwent SDL and 63 underwent TDL. Operative time, intraoperative bleeding amount, and fluoroscopy time were significantly reduced in patients who underwent TDL compared to those who underwent SDL. The union times were found to be significantly shorter in TDL patients. There was no significant difference between the groups in terms of postoperative Harris hip score and VAS score results and complications. Conclusions: This clinical study confirms that TDL is as effective and safe as SDL. In addition, TDL has been shown to have advantages over SDL with shorter operative time, less bleeding amount, and less fluoroscopy time.

Development and validation of models for predicting mortality in intertrochanteric fracture surgery patients with perioperative blood transfusion: a prospective multicenter cohort study.

The association between allogenic blood transfusions (ABT) and all-cause mortality in surgically treated hip fracture patients with perioperative transfusion (STHFPT) remained unknown. We aim to introduce transfusion-related factors, new variables to develop and validate models to predict mortality in these patients. A prospective multicenter cohort study was conducted with STHFPT hospitalized during Jan. 2018 and Jun. 2021. The database was divided into training cohort and validation cohort in a ratio of 70% to 30% using the randomization method. All participants received a minimum of 2-year follow-up and all participants' overall and eight time-specific survival status were recorded. Prediction models were developed using multivariate logistic regression and Cox regression for variable selection. Model performance was measured by determining discrimination, calibration, overall model performance or precision, and utility. Sensitivity analyses were performed to test robustness of the results. A total of 7074 consecutive patients were prospectively screened and assessed for eligibility to participate. Finally, 2490 patients met our inclusion and exclusion criteria and 1743 (70%) patients were randomized to the training cohort and 747 (30%) to the validation cohort. The median duration of follow-up was 38.4 months (IQR 28.0-62.0). Our novel models highlight that preoperative transfusion is of significance for short-term mortality while mid-term outcomes are predominantly determined by severe complications, pulmonary complications, and advanced age. Our models showed high discriminative power, good calibration and precision for mortality prediction in both training and validation cohorts, especially in short-term mortality prediction. We introduce transfusion-related factors, new variables to develop and validate models to predict mortality with STHFPT. The models can be further tested and updated with the ultimate goal of assisting in optimizing individual transfusion strategy.

The Effect of Intraoperative Patient Positioning on the Success of Intertrochanteric Fracture Surgery in Older Patients.

Background and Objectives: The incidence of hip fractures in people of advanced ages is increasing due to our aging society. Patient positioning for the intertrochanteric fractures of the femur can be performed in various ways. The aim of this study is to clinically and radiologically compare the use of the supine hemilithotomy position, the lateral decubitus position, and the traction table when performing proximal femoral nail (PFN) surgery for femoral intertrochanteric fractures in the geriatric age group. Materials and Methods: A total of 170 elderly patients with femoral intertrochanteric fractures were included in this cross-sectional study. The patients were divided into three groups (the supine hemilithotomy group, the lateral decubitus group, and the fracture table group). For the postoperative period, complications, length of stay in the intensive care unit, and length of stay in hospital were examined, while in postoperative radiographs, tip-apex distances (TADs), collodiaphyseal angles (CDAs), and Cleveland-Bosworth quadrants were examined to evaluate the placement of the lag screw in the femoral head. The quality of fracture reduction was evaluated according to the modified Baumgaertner criteria. Results: The mean age of the patients was 77.8 ± 8.8; 57.6% of patients were female. According to the modified Baumgaertner criteria, it was determined that patients with 'poor' reduction quality had an approximately ten times higher risk of cut-out than those with 'good' reduction quality (OR = 10.111, p = 0.002, 95% confidence interval; 2.313-44.207). The operative time for patients in the fracture table group was longer than that of the other groups Additionally, the CDA in the supine hemilithotomy position group was longer. Conclusions: Although PFN surgery using the traction table is longer in terms of surgical time compared to surgery performed in the lateral decubitus position and the supine hemilitotomy position, it is advantageous in terms of better TAD and CDA values and lower complication rates.

Radiological Differences Following Proximal Femoral Nail Antirotation (PFNA) Compared to the Contralateral Side and Its Correlation with Harris Hip Score (HHS) in Intertrochanteric Femoral Fracture After Three Months

Introduction: The incidence of intertrochanteric femoral fractures, which account for 50% of all hip fractures, is increasing as a result of the aging population. While PFNA surgery typically enhances outcomes, certain individuals continue to have pain, stiffness, and difficulties with their gait. This study aims to determine whether there is a correlation between post-surgical complications and changes in hip joint angles assessed three months following PFNA to lead future advances in PFNA surgery for older persons by comparing impacted and unaffected hips and correlating angles with patients' hip ratings. Methods: This study included 42 individuals who underwent surgery for intertrochanteric fractures aged 50 and above. Eligible participants must possess the ability to walk before to the study, have no history of previous leg fractures, and be capable of participating in rehabilitation. Individuals having comorbidities impacting these aspects or those unable to partake were not included. Result : This study looked at hip angles in 42 people who had surgery intertrochanteric fracture. While the participants varied in age and gender, the surgery itself didn't seem to significantly change the angles of their hip bones or their ability to walk. This suggests that PFNA may not directly affect hip mechanics on its own. Conclusion: This study indicates that attaining acceptable hip angles during the procedure could enhance patients' mobility and post-operative condition. Further investigation involving bigger cohorts and extended periods of observation is necessary to validate these findings and ascertain whether modifying these angles during surgery will result in improved outcomes following PFNA.

Sagittal support rather than medial cortical support matters in geriatric intertrochanteric fracture: A finite element analysis study

Hip fracture, increasing exponentially with age, is osteoporosis's most severe clinical consequence. Intertrochanteric fracture, one of the main types of hip fracture, is associated with higher mortality and morbidity. The current research hotspots lay in improving the treatment effect and optimizing the secondary stability after intertrochanteric fracture surgery. Cortex buttress reduction is a widely accepted method for treating intertrochanteric fracture by allowing the head-neck fragment to slide and rigidly contact the femoral shaft's cortex. Medial cortical support is considered a more effective option in treating young patients. However, osteo-degenerations features, including bone weakness and cortical thickness thinning, affect the performance of cortex support in geriatric intertrochanteric fracture treatment. Literature focusing on the age-specific difference in cortex performance in the fractured hip is scarce. We hypothesized that this osteo-19 degenerative feature affects the performance of cortex support in treating intertrochanteric fractures between the young and the elderly. We established twenty models for the old and the young with intertrochanteric fractures and performed static and dynamic simulations under one-legged stance and walking cycle conditions. The von Mises stress and displacement on the femur, proximal femoral nail anti-rotation (PFNA) implant, fracture plane, and the cutting volume of cancellous bone of the femur were compared. It was observed that defects in the anterior and posterior cortical bone walls significantly increase the stress on the PFNA implant, the displacement of the fracture surface, and cause a greater volume of cancellous bone to be resected. We concluded that ensuring the integrity and alignment of the anterior and posterior cortical bones is essential for elderly patients, and sagittal support is recommended. This finding suggests that the treatment method for intertrochanteric fracture may differ, considering the patient's age difference.

Effects of ultrasound-guided lumbar plexus and sacral plexus block combined with general anesthesia on the anesthetic efficacy and surgical outcomes in elderly patients undergoing intertrochanteric fracture surgery: a randomized controlled trial

BackgroundSurgery for intertrochanteric fractures in elderly patients is challenging due to the risk of severe pain and significant stress responses. We investigated the effects of a combined approach of ultrasound-guided lumbar plexus and sacral plexus block with general anesthesia on anesthetic efficacy and surgical outcomes in these patients.MethodsA randomized controlled trial was conducted involving 150 elderly patients, divided into two groups: the combined anesthesia group (receiving ultrasound-guided lumbar plexus and sacral plexus block along with general anesthesia) and the general anesthesia alone group. Outcome measures included hemodynamic parameters, postoperative pain levels (VAS scores), postoperative recovery times, and incidence of adverse reactions.ResultsIn the combined anesthesia group, the patients had more stable intraoperative hemodynamics, lower postoperative VAS scores at 1, 3, and 6 h, and faster recovery times (eye-opening upon command and return of respiratory function) compared to the general anesthesia group. Furthermore, the incidence of adverse reactions was significantly lower in the combined anesthesia group.ConclusionsUltrasound-guided lumbar plexus and sacral plexus block combined with general anesthesia enhanced the anesthetic efficacy and improved surgical outcomes in elderly patients undergoing intertrochanteric fracture surgery.

Does early administration of denosumab delay bone healing after intertrochanteric femoral fractures?

IntroductionHip fractures are commonly associated with osteoporosis and pose a risk for secondary fractures. Although the administration of anti-osteoporotic drugs is recommended after fractures to mitigate this risk, the potential effect of strong anti-resorptive drugs (e.g., denosumab) on fracture healing processes have not been extensively studied. This prospective study aimed to evaluate the feasibility of early denosumab administration after femoral intertrochanteric fracture surgery and to compare its effect on fracture healing to that of bisphosphonate-treated patients. Materials and MethodsPatients who underwent surgery for intertrochanteric femoral fragility fractures between November 2018 and November 2020 were prospectively examined. Patients were randomized into two groups (denosumab [DSM] and ibandronate [IBN] groups) using a simple randomization procedure. Physical findings, plain radiographs, and computed tomography (CT) were used to evaluate fracture healing at 3 months postoperatively. ResultsPhysical findings showed no significant differences between the two groups in pain on loading, tenderness at fracture site, or walking ability. There were inter-rater differences in radiological fracture healing rate: plain radiographs, 57.5% to 81.8% in the DSM group and 51.5% to 90.9% in the IBN group; CT, 51.5% to 72.7% in the DSM group and 45.4% to 81.8% in the IBN group. Although there were variations, there were no significant differences in the fracture healing rate between groups on plain radiographs or CT among all three raters. ConclusionsEarly administration of denosumab after intertrochanteric femoral fracture surgery did not delay radiological or clinical fracture healing times when compared with ibandronate administration.

Six-Part Classification of Femoral Intertrochanteric Fractures: A Classification Method to Improve the Diagnosis Rate of Unstable Fractures.

Three-dimensional (3D)-CT data is currently insufficient for classifying femoral trochanter fractures. Fracture classification based on fracture stability analysis is helpful to evaluate the prognosis of patients after internal fixation. Currently, there is a lack of fracture classification methods based on 3D-CT images and fracture stability analysis. The aim of this study was to propose a new six-part classification method for intertrochanteric fractures of femur based on 3D-CT images and fracture stability analysis to improve the diagnosis rate of unstable fractures. From January 2009 to December 2019, 320 patients receiving intramedullary nail surgery for femoral intertrochanteric fractures at Chengdu University's Affiliated Hospital were studied retrospectively. AO and six-part classifications were undertaken according to the 3D-CT image data of the patients, and the stability rates of two classifications were compared. According to the six-part classification stability criteria, the patients were divided into a stable and an unstable fracture group. The perioperative and follow-up indicators of the two groups were statistically analyzed, and the six-part classification's inter-observer and internal reliability was examined. There were 107 men and 213 females women the 320 patients, with an average age of 79.32 ± 11.26 years and an osteoporosis rate of 55.63% (178/320). The fracture stability rate of 39.69% (127/320) was studied using a six-part classification method. The AO classification fracture stability rate was 42.50% (136/320), with no significant difference (χ2 = 0.523, p = 0.470 > 0.05). There is no statistically significant difference between the two classification techniques in the examination of fracture stability (McNemer difference test p = 0.306 > 0.05; Kappa consistency test p < 0.001). According to the six-part classification, fracture stability and instability group were divided into two groups. The following indicators were compared between the two groups: The surgery time (p = 0.280), fracture reduction quality (p = 0.062); function independent measurement (p = 0.075); timed up and go test (TUG) (p = 0.191), and Parker-Palmer score (p = 0.146). Were as compared according to the six-part classification of stable and unstable fracture groups. Perioperative blood loss (p < 0.001), the Harris score excellent and good rate (p = 0.043), fracture healing time (p < 0.001), and the entire weight-bearing duration (p = 0.002) were statistically significant. The difference in femoral head height (FHH) (p = 0.046), the change in femoral neck shaft angle (p = 0.003), the change in medial cephalic nail length (p = 0.033), and the change in tip-apex distance (TAD) (p = 0.002) were statistically significant compared to the relevant markers of imaging stability. Fracture stability had a substantial influence on Harris ratings at 3, 6, and 12 months following surgery, according to repeated measures analysis of variance (F(1,126) = 32.604, p < 0.001). The effect of time on the Harris score was similarly significant (F(1.893,238.508) = 202.771, p < 0.001). The observer intra-observer inter-group correlation coefficient (ICC) value was 0.941 > 0.75, the inter-observer ICC value was 0.921 > 0.75, and the intra-observer and inter-observer reliability were both good. The six-part classification of femoral intertrochanteric fractures based on 3D-CT images has broader guiding relevance for femoral intertrochanteric fracture stability analysis. Clinicians will find this classification simpler and more consistent than the AO classification.

Feasibility of diagnosing osteoporosis using routine computed tomography scans for hip fractures: Correlation with histopathological diagnosis of head and neck regions.

The aim of this study was to demonstrate the feasibility of diagnosing osteoporosis through routine computed tomography (CT) by assessing the association between the histopathological assessment of femoral head specimens extracted from patients who underwent surgery for intertrochanteric fractures and the Hounsfield unit (HU) measurements derived from preoperative CT scans. Forty-eight patients who presented to our clinic between November 2019 and May 2020 with hip fractures and underwent partial prosthesis fixation were included in this retrospective study. Hounsfield unit measurements were performed on the head and neck regions using dual-energy x-ray absorptiometry (DEXA) and CT scans, respectively. The trabecular ratio per unit area was calculated using the Nikon Imaging Software (NIS-Elements ) program in the pathology laboratory from digitally captured images of the removed head and neck specimens. The mean HU receiver operating characteristic analysis had a sensitivity of 77% and a specificity of 87%, with a cutoff value of 77.68. There was a moderate correlation between the mean trabecular density and the mean HU of the femoral head (P=0.013, r=0.340). Additionally, there was a significant correlation between the mean HU and the T-score of the head, although this correlation was not found with the maximum-minimum HU. Although there was a significant correlation between trabecular density and mean HU, the correlation coefficient indicated a moderate relationship. This relationship was also observed between the inferior sections of the head and the trabecular density and HU (P=.018). However, no significant correlation was found between the T-score and the trabecular structure of the head (P=.977). The results of the present study suggest that conventional CT has the potential to serve as a diagnostic tool for osteoporosis and may offer a more precise and accurate method for evaluating the success of intraosseous implants when compared to T-scores without the need for additional tests or procedures.

The Efficiency of Antiosteoporosis Medicine after Intertrochanteric Fracture Surgery: A Retrospective Study of Refracture Rate, Function Recovery, Complications, and Mortality in the Chinese Elderly Population

Abstract Objective This research aimed to discern the effects of antiosteoporosis medication on postoperative functional recovery, refracture incidence, complications, and mortality in geriatric patients with intertrochanteric fractures. Methods A retrospective study was conducted on 250 patients aged 65 years and above who underwent surgery for intertrochanteric fractures between January 2013 and December 2014. Intertrochanteric fracture is diagnosed with International Classification of Diseases 10th Revision code (S72.101) and classified by the Evans–Jensen system. Collected data encompassed demographic details, pre- and postoperative histories of antiosteoporotic medication, functional outcomes (measured using Harris hip score, Parker Mobility Score, and EuroQol-5 Dimension [EQ-5D] scores), refracture incidences, complications, and survival rates. The antiosteoporotic regimen was categorized into essential (calcium, vitamin D) and advanced medications (bisphosphonate, calcitonin, etc.). Outcomes between patients on antiosteoporosis treatment (AO group) and those without (control group) were compared. Results The cohort comprised 250 patients, with a gender distribution of 85 males (34%) and 165 females (66%), and a mean age of 79.8 ± 7.0 years. The median follow-up period was 15.82 months (maximum 31.13 months). Postoperatively, 126 (50.4%) patients were administered antiosteoporotic treatment. The refracture incidence in the AO group (2.4%, n = 3) was notably lower than the control group (8.9%, n = 11), manifesting a substantial risk reduction (odds ratio 0.251, 95% confidence interval 0.068–0.920, p = 0.024). While no marked differences in functional outcomes between the AO and control groups were observed (Harris score [96.17 ± 7.77 vs. 97.29 ± 6.74, p = 0.074), Parker score [8.54 ± 1.26 vs. 8.62 ± 1.18, p = 0.411], EQ-5D [0.83 ± 0.05 vs. 0.82 ± 0.06, p = 0.186]), patients administered a combination of essential and advanced drugs showcased significantly improved Harris and EQ-5D scores compared to those on essential drugs alone (Harris score [77.93 ± 2.04 vs. 84.94 ± 2.73, p = 0.015], EQ-5D [0.65 ± 0.03 vs. 0.75 ± 0.04, p = 0.015]). Conclusion Postoperative antiosteoporosis treatment acts as a deterrent against refracture following intertrochanteric fracture surgeries, evidenced by a decline in refracture rates. However, the treatment's impact on functional recovery, quality of life, complications, and mortality remains indistinct. Interestingly, the combined administration of essential and advanced antiosteoporotic drugs seems to foster enhanced functional outcomes, warranting further exploration in future studies.

Intramedullary administration of tranexamic acid reduces bleeding in proximal femoral nail antirotation surgery for intertrochanteric fractures in elderly individuals: A randomized controlled trial

PurposeIntertrochanteric fractures undergoing proximal femoral nail antirotation (PFNA) surgery are associated with significant hidden blood loss. This study aimed to explore whether intramedullary administration of tranexamic acid (TXA) can reduce bleeding in PFNA surgery for intertrochanteric fractures in elderly individuals. MethodsA randomized controlled trial was conducted from January 2019 to December 2022. Patients aged over 60 years with intertrochanteric fractures who underwent intramedullary fixation surgery with PFNA were eligible for inclusion and grouped according to random numbers. A total of 249 patients were initially enrolled, of which 83 were randomly allocated to the TXA group and 82 were allocated to the saline group. The TXA group received intramedullary perfusion of TXA after the bone marrow was reamed. The primary outcomes were total peri-operative blood loss and post-operative transfusion rate. The occurrence of adverse events was also recorded. Continuous data was analyzed by unpaired t-test or Mann-Whitney U test, and categorical data was analyzed by Pearson Chi-square test. ResultsThe total peri-operative blood loss (mL) in the TXA group was significantly lower than that in the saline group (577.23 ± 358.02 vs. 716.89 ± 420.30, p = 0.031). The post-operative transfusion rate was 30.67 % in the TXA group and 47.95 % in the saline group (p = 0.031). The extent of post-operative deep venous thrombosis and the 3-month mortality rate were similar between the 2 groups. ConclusionWe observed that intramedullary administration of TXA in PFNA surgery for intertrochanteric fractures in elderly individuals resulted in less peri-operative blood loss and decreased transfusion rate, without any adverse effects, and is, thus, recommended.

Adjuvant Vitamin D Injection in Elderly Patients Before Intertrochanteric Fracture Surgery: A Randomised Controlled Trial.

There are multiple recommended protocols for Vitamin D (VitD) supplementation in elderly; however, only a few studies achieved to examine the role of VitD supplements before intertrochanteric fracture surgery on mortality and complications after surgery. This single-center block-randomized double-blinded trial was conducted on 80 patients with intertrochanteric fractures and a sufficient level of 25 (OH) VitD. The intervention group received an intramuscular 300,000IU VitD ampule before surgery. The primary outcome was a 6-month mortality rate, and the secondary outcomes were 1- and 2-year mortality rates and Harris Hip Score (HHS) in 6, 12, and 24months after surgery. Chi-square, t-test, repeated measure ANOVA, and Cox regression survival model was used for statistical analysis. 40 patients were allocated to each group. Demographic, clinical characteristics, and preoperative evaluations were not significantly different between the groups. Mortality rate 6-month after the surgery was 7.5% and 10% for the intervention and placebo groups respectively (P value = .71), 15% and 12.5% at 1-year (P value = .83), and 25% and 27.5% at 2-year (P value = .98). Based on the Cox regression model, only age was significantly associated with mortality (HR = 1.229, P value <.001). Significant HHS changes from baseline through 24 months after surgery were observed within both groups; however, mean differences were not significantly different between groups. A single preoperative 300,000IU VitD did not significantly impact 2-year survival and HHS in patients with intertrochanteric fractures and sufficient serum VitD level.

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

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. 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. 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. 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.

Effect of rapid rehabilitation care on surgical site wound infection and pain in patients with intertrochanteric femoral fractures: A meta-analysis.

This study examines the effects of rapid rehabilitation on surgical site wound infections and pain in patients with intertrochanteric femoral fractures. A computerised search was conducted for randomised controlled trials (RCTs) on rapid rehabilitation care in patients undergoing surgery for intertrochanteric femoral fractures published in the China National Knowledge Infrastructure, China Biomedical Literature Database, Wanfang Database, VIP, PubMed, Embase, Cochrane Library and Web of Science. The search was conducted from the time of the database construction to August 2023. Two investigators independently performed literature screening, data extraction and quality assessment based on predefined inclusion and exclusion criteria. Meta-analysis was performed via RevMan 5.4 software. Encompassing 21 studies involving 2004 patients, with 1007 patients receiving rapid rehabilitation care and 997 receiving routine care, our analysis revealed that rapid rehabilitation care significantly reduced postoperative complications (odds ratio [OR] = 0.24, 95% confidence interval [CI]: 0.17-0.33, p < 0.001), wound infections (OR = 0.30, 95% CI: 0.14-0.65, p = 0.002) and hospital stay (mean difference [MD] = -5.23, 95% CI: -6.03 to -4.43, p < 0.001). Moreover, compared with routine care, it notably improved wound pain (MD = -1.51, 95% CI: -1.98 to -1.05, p < 0.001) in patients undergoing surgery for intertrochanteric femoral fractures. Our findings underscore the effectiveness of rapid rehabilitation care in reducing wound pain, postoperative complications and wound infections among patients with intertrochanteric femoral fractures.

Computer-Assisted Intramedullary Nailing of Intertrochanteric Fractures Did Not Prevent Tip–Apex Distance Outliers

Intertrochanteric femoral fractures are commonly treated with intramedullary nails (IMNs). A tip–apex distance (TAD) of more than 20–25 mm is associated with an increased risk of cut-out. The Stryker Adaptive Positioning System (ADAPT) is a computer-assisted navigation system designed to reduce TADs. We aim to assess if the ADAPT reduces the number of outliers with a TAD &gt; 20 mm. All patients with intertrochanteric fractures treated with an IMN between 1 September 2020 and 12 March 2022 were included. Patients were included in three periods: a pre-ADAPT period (55 patients); an ADAPT period (50 patients), where it was compulsory to use the system; and a post-ADAPT period after the discontinuation of the system (59 patients). The TADs and lag screw protrusions beyond the lateral cortex were measured. The median TADs in the three periods were 17.0 mm (8–31 mm), 15.5 mm (9–30 mm), and 18.0 mm (11–32 mm), respectively. The absolute number of outliers with a TAD &gt; 20 mm decreased from 15/55 patients in the pre-ADAPT period to 11/50 patients during the ADAPT period. This observation was not statistically significant, but this is likely due to the lack of power of the present study to show changes of this magnitude. However, our expectation that the ADAPT would diminish outliers markedly or close to zero outliers was not met, as we observed 11/50 = 22% outliers with a TAD &gt; 20 mm when using computer-assisted surgery, i.e., ADAPT and Gamma3 for intertrochanteric fractures. Based on these findings, the use of the ADAPT was discontinued at our level 1 trauma center.
