Investigation of Novel Radiological Parameters to Predict Treatment Failure and Ideal Surgical Interventions in Young Femoral Neck Fractures Treated with Triple Cannulated Screw: A Retrospective Analysis.

Treatment failure remains a challenge in young femoral neck fractures treated with triple cannulated screws (TCS). This study aims to identify novel radiological parameters that can predict treatment failure and propose surgical techniques to enhance the success of TCS or aid in selecting alternative methods. We conducted a retrospective analysis of 87 patients who underwent surgery for femoral neck fractures between February 2014 and June 2022, meeting the inclusion criteria. Patients achieving union were categorized as Non-Fail (Group 1), while those experiencing nonunion were categorized as Fail (Group 2). Various demographic and clinical factors were assessed, including age, gender, fracture side, and fracture classification (Garden and Pauwels). Radiological parameters such as fragmentation in the medial cortex, postoperative fracture displacement in the calcar region, collo-diaphyseal angle (CDA) difference (varus/valgus alignment), and several newly defined parameters (modified tip apex distance (m-TAD), tip cortex distance (TCD), upper-lower screw-cortex distance/neck diameter, the calcar screw-cortex distance/neck diameter (Buyukdogan index), and sub-capital area/basocervical area (Dogan index) were evaluated. Patients developing nonunion were studied to establish potential cut-off values based on radiological parameters. Of the patients, 61 were classified as Non-Fail (Group 1) and 26 as Fail (Group 2). Both groups exhibited similar distributions in terms of gender, fracture side, Pauwels classification, and follow-up times (p > 0.05). However, Group 2 had a higher mean age than Group 1 (p = 0.006). There was a significant difference between the two groups in terms of Garden classification (p = 0.0003). Furthermore, postoperative calcar displacement, varus alignment, m-TAD, TCD, upper-lower screw-cortex distance/neck diameter ratio, Buyukdogan index, and Dogan index showed significant differences between the groups (p < 0.05). Conversely, medial calcar fragmentation did not differ significantly between the groups (p > 0.05). The Dogan index (≤ 0.5) can serve as an independent preoperative predictor of treatment failure, aiding in the selection of more effective surgical interventions than TCS. Varus alignment (> 10 degrees), the upper-lower screw-cortex distance to the neck diameter (> 0.45) and Buyukdogan index (> 0.2) are influenced by the surgical technique of TCS application and should be considered to decrease the success of TCS.

A perforation of a duodenal diverticulum in a 97-year-old patient after total gastrectomy and Roux-en-Y reconstruction: a case report

Most duodenal diverticula (DD) are asymptomatic and rarely develop perforations. Perforation is the most serious complication of DD and often requires emergency surgery. A 97-year-old woman who had undergone total gastrectomy and Roux-en-Y reconstruction 30 years ago was referred to our department with chief complaints of abdominal pain and fever during her hospitalization after femoral neck fracture surgery in the orthopedic department. Contrast-enhanced computed tomography showed free air and residue in the abdominal cavity and right retroperitoneum, and an emergency laparotomy was performed. The abdominal cavity was mildly contaminated, and a 6-cm DD with a 1-cm perforation in the wall of the diverticulum on the contralateral side of the mesentery of the duodenum was found. Diverticulectomy and duodenal closure were performed and a drainage tube was placed. The patient experienced no complications and was transferred to the orthopedic department on postoperative day 10. Reports of perforation of DD after gastrectomy are very rare. Particular attention should be paid to perforation of DD after Billroth-II and Roux-en-Y reconstructions as they involve the formation of a duodenal stump that differs from the normal anatomy and may be highly invasive surgical procedures, depending on the degree of inflammation and fistula formation.

Trends and benefits of early hip arthroplasty for femoral neck fracture in China: a national cohort study.

Limited studies have examined the benefits of early arthroplasty within 48h from admission to surgery for femoral neck fractures (FNFs). Using the national inpatient database, the authors aimed to investigate the trends in early arthroplasty within 48h for FNFs in China and to assess its effect on in-hospital complications and 30-day readmission patterns. This was a retrospective cohort study. Patients receiving primary total hip arthroplasty (THA) or hemiarthroplasty (HA) for FNFs in the Hospital Quality Monitoring System between 2013 and 2019 were included. After adjusting for potential confounders with propensity score matching, a logistic regression model was performed to compare the differences in in-hospital complications [i.e. in-hospital death, pulmonary embolism, deep vein thrombosis (DVT), wound infection, and blood transfusion], rates and causes of 30-day readmission between early and delayed arthroplasty. During the study period, the rate of early THA increased from 18.0 to 19.9%, and the rate of early HA increased from 14.7 to 18.4% ( P <0.001). After matching, 11731 pairs receiving THA and 13568 pairs receiving HA were included. Compared with delayed THA, early THA was associated with a lower risk of pulmonary embolism [odds ratio (OR) 0.51, 95% CI: 0.30-0.88], DVT (OR 0.59, 95% CI: 0.50-0.70), blood transfusion (OR 0.62, 95% CI: 0.55-0.70), 30-day readmission (OR 0.82, 95% CI: 0.70-0.95), and venous thromboembolism-related readmission (OR 0.50, 95% CI: 0.34-0.74). Similarly, early HA was associated with a lower risk of DVT (OR 0.70, 95% CI: 0.61-0.80) and blood transfusion (OR 0.74, 95% CI: 0.68-0.81) than delayed HA. Despite a slight increase, the rate of early arthroplasty remained at a low level in China. Given that early arthroplasty can significantly improve prognosis, more efforts are needed to optimize the procedure and shorten the time to surgery.

Real-time traking and virtual reality technology-assisted trauma orthopaedic surgery robot for femoral neck fractures

To investigate the effectiveness of real-time tracking and virtual reality technology（RTVI） used to assist the intraoperative alignment of the trauma orthopaedic surgery robot for the treatment of femoral neck fractures and its impact on the treatment outcome. A retrospective analysis was conducted on 60 patients with femoral neck fractures treated with trauma orthopedic robotic surgery from September 2020 to September 2022. Patients were divided into two groups according to whether RTVI technology was used during surgery to assist robotic surgery. There were 28 patients in the RTVI group （12 males and 16 females）, with an average age of （46.2±9.3） years old ranging from 28 to 60 years old. There were 32 patients in the simple Tianji surgical robot group, including 15 males and 17 females, aged （48.2±7.8） years old ranging from 32 to 58. The number of registered fluoroscopy, operation time, total number of intraoperative fluoroscopy, intraoperative blood loss, and hospitalization time of the two groups of patients were observed and recorded. All patients received regular follow-up after surgery, and hip X-rays were routinely reviewed to record Garden alignment index, fracture healing time, postoperative complications, and Harris score. All 60 patients were followed up. The RTVI group was followed up for 9 to 16 months with an average of （13.0±1.2） months, and the Tianji surgical robot group alone was followed up for 10 to 14 months with an average of （12.0±1.3） months. During the follow-up period, the femoral neck fractures of both groups of patients healed well, and no complications such as internal fixation loosening and incision infection occurred. The number of registered fluoroscopy, operation time, and number of intraoperative fluoroscopy of patients in the RTVI group were significantly better than those in the simple Tianji surgical robot group（P<0.01）. There was no statistically significant difference in intraoperative blood loss, hospital stay, Garden alignment index, fracture healing time, and hip Harris score between two groups（P>0.05）. Although RTVI technology assisted by the surgical robot for femoral neck fracture surgery has little impact on its postoperative outcome, it can effectively reduce the operating time, the number of intraoperative X-ray projections, and the risk of intraoperative radiation exposure to patients. It also shortened the learning curve of the operator and better reflected the precision and efficiency of the trauma orthopaedic surgery robot.

A Rare Complication of Intraprosthetic Dissociation of Cemented Bipolar Hemiarthroplasty during Closed Hip Reduction: Case Report and Literature Review

AbstractHip hemiarthroplasty (HA) remains a frequently performed surgery for femoral neck fractures especially in the oldest, lowest demand patients. Debate persists concerning the optimal choice between unipolar and bipolar HA implants. A rare but important to recognize complication unique to bipolar HA is intraprosthetic dissociation (IPD). We review the literature on this rare phenomenon and identify predominant etiologies and implant components most involved in IPD, notably the role of hip dislocation and closed reduction in precipitating this complication. We also describe an elderly male patient with Parkinson's who experienced IPD of his bipolar HA during a closed reduction attempt. IPD typically requires open reduction and possibly revision of components, adding increased risk of reoperation/revision to those already frail and vulnerable to surgical complications.

Risk Factors for Loss to Follow-up of Elderly Patients After Hip Fracture Surgery: A Retrospective Cohort Study.

Non-attendance with scheduled postoperative follow-up visits remains a common issue in orthopaedic clinical research. The objective of this study was to identify the risk factors associated with loss to follow-up among elderly patients with hip-fracture postoperatively. A retrospective analysis of 1-year post-surgery was performed on patients aged over 60 years who underwent hip-fracture surgery from January 2017 to March 2019. Based on their completion of the appointed follow-up schedule, the patients were classified into 2 groups: the Loss to Follow-up (LTFU) Group and the Follow-up (FU) Group. Clinical outcomes were evaluated by Functional Recovery Score (FRS) questionnaires. Telephone interviews were conducted with patients lost to follow-up to determine the reasons for non-attendance. A comparative analysis of baseline characteristics between the 2 groups was implemented, with further exploration of statistical differences through logistic regression. A total of 992 patients met the inclusion criteria were included in this study, of which 189 patients, accounting for 19.1%, were lost to follow-up 1 year postoperatively. The mean age of the patients in the LTFU Group was 82.0years, significantly higher than the 76.0years observed in the FU Group (P < 0.001). The FRS for the LTFU Group was marginally higher than that of the FU group (84.0 vs 81.0), with no significant difference (P = 0.060). Logistic regression analysis identified several significant predictors of noncompliance, including advanced age at surgery, femoral neck fracture, hip arthroplasty, long distance from residence to hospital, and the reliance on urban-rural public transportation for reaching the hospital. Postoperative follow-up loss was prevalent among elderly patients with hip fractures. Our study indicated a constellation of risk factors contributing to noncompliance, including advanced age, transportation difficulties, long travel distance, femoral neck fracture and hip arthroplasty surgery.

Mobility following femoral neck fracture surgery: Does surgical treatment affect outcome?

BACKGROUND: Hip fractures are a life changing injury for many; often patients sustaining a hip fracture do not regain their pre-injury function. Early rehabilitation improves patient outcomes (e.g. Mobility, independence &amp; function). OBJECTIVES: The aim of this study was to investigate whether patients with hip fracture progressed differently depending on their surgery type, specifically whether arthroplasty or internal fixation (IF) was employed as part of the surgical management. METHODS: A prospective audit was completed on hip fracture patients presenting to our unit between October 2019 and October 2020 who received surgical intervention for their fracture. The audit collected data on patient outcomes, specifically Timed Up and Go scores (TUG), Discharge destination and Cumulative Ambulatory Scores. The study group comprised 89 patients with femoral neck fractures (60 females, 29 males). The average age was 77 (range 50–96) years. Sixty-nine patients were managed with an arthroplasty, 20 patients were managed with IF. RESULTS: Results from this audit highlighted that at discharge, TUG scores had improved in both groups with the arthroplasty group completing their TUG in a mean of 46 seconds (median 39 seconds) and the IF group in a mean of 55.7 seconds (median 46 seconds). Eleven (55%) of the patients treated with IF were discharged home directly, while 26 (38%) of the patients treated with an arthroplasty were discharged home directly. Hip fracture patients treated with arthroplasty had lower functional ability on day one post-operatively based on the CAS. Patients treated with arthroplasty showed greater improvement in function and mobility at the time of discharge when compared to the IF group. A greater proportion of the IF group were discharged directly home (55% vs 38%) and able to receive any ongoing rehabilitation as an outpatient while a greater portion of the arthroplasty group required further inpatient rehabilitation (35% vs 48%). CONCLUSION: This audit indicated that irrespective of surgical intervention (Arthroplasty or IR) there is little difference in patient outcomes in the post-operative period.

Management of Femoral Neck Fractures in Patients Age ≥50 Years by American Board of Orthopaedic Surgery Part II Examination Candidates.

Assess associations between fellowship training, procedure, and performance in femoral neck fracture (FNF) surgery on adults by American Board of Orthopaedic Surgery (ABOS) Part II Examination candidates. ABOS SCRIBE database exam years 2007-2020. 6,777 candidates performing 39,283 FNF surgeries on adults age ≥ 50 years. Fellowship training. Case volume; procedure performed: internal fixation (IF), hemiarthroplasty (HA), or total hip arthroplasty (THA); complications; readmission; reoperation. Over the observation period, fewer candidates reported FNF surgery (68% overall, -0.6%/year, R2=0.80) while more candidates reported fellowship training (87% overall, +1.4%/year, R2=0.81). The rate of any complication was significantly associated with fellowship training (32% overall, p<0.001). Readmission (12%, p=0.080) and reoperation (5%, p=0.531) were not significantly associated with fellowship training. The odds of any complication (odds ratio [OR]=-0.03 [95% CI -0.07 to -0.001] per 10 cases) and surgical complication (OR=-0.12 [95% CI -0.17 to -0.07] per 10 cases) were negatively associated with candidate FNF case volume. 3,396 THA for FNF were performed (8% of cases). THA use increased 25 cases/year (R2=0.83) and was associated with adult reconstruction (p<0.001) and oncology (p<0.001) fellowship training. Any complication of THA for FNF (32%, p=0.261), readmission (9% overall, p=0.321), and reoperation (5%, p=0.200) were not significantly associated with fellowship training. Between 2007-2020, femoral neck fracture surgery was performed by fewer ABOS Part II Examination candidates and there was greater use of THA. Over this time period there was a greater prevalence of fellowship training but complications were not associated with fellowship training. Complications were associated with FNF case volume.

The effect of the Ankle Pump Exercise (APE) counter system assisted ankle pump motion in patients after femoral neck fracture

ObjectiveTo explore the effect of the Ankle Pump Exercise (APE) counter system on moderate to high-risk Venous thromboembolism (VTE) after femoral neck fracture surgery.MethodsFrom June 2021 to June 2022, a total of 140 patients with moderate and high-risk VTE after femoral neck fracture surgery treated at the Department of Orthopedics of a tertiary hospital in Zhejiang were included and divided into observation (70 cases) and control (70 cases) groups according to whether APE counter system was used or not. The control group was given routine oral propaganda, and the observation group was given a comprehensive nursing intervention with APE counter system on the basis of the control group’s treatment. The compliance rates of the two groups on the postoperative 3st, 5rd, and 7th days were compared. Moreover, the General self-efficacy scale (GSES) was used to evaluate self-efficacy before and after exercise.ResultsThe compliance rates of the control group and the observation group on the postoperative 3st, 5rd, and 7th days were 74.3% vs. 85.7%, 67.1% vs. 85.7%, and 61.4% vs. 82.9%. On the 5rd and 7th days, the compliance of the observation group was obviously higher than that of the control group. Moreover, the mean postoperative GSES score was also significantly higher than that in the control group (23.20 ± 3.516 vs. 25.31 ± 4.583, P < 0.05, values are expressed in mean ± standard).ConclusionAPE counter system can significantly improve the compliance and self-efficacy of patients with moderate and high-risk VTE after lower limb fracture surgery.

The Role of Endoscopy in Investigating the Causes of Persistent Anaemia in Post-operative Fractured Neck of Femur Patients.

Introduction Post-operative anaemia in hip fracture patients has been associated with increased risk of blood transfusion, poorer functional outcomes, increased morbidity and mortality. Patients with persisting drop in haemoglobin after fractured neck of femur with no obvious source of blood loss are often referred for endoscopy to find the cause of anaemia. The reported incidence of perioperative acute upper gastrointestinal bleeding varies from 1 to 15%. Objective The aim of our study is to find out the usefulness of endoscopy in finding gastrointestinal causes leading to the occult loss of blood causing irreversible anaemia in post-operative neck of femur fractures. Material and methods The orthogeriatric unit conducted a study using retrospective dataon neck of femur fracture patients from January 2015 to December 2020. Out of 1863 cases, 918 (49.3%) developed post-operative anaemia. Forty-five patients (5%) with refractory anaemia underwent endoscopy referral. Patient demographics, fracture patterns, pre-existing anaemia, and co-morbidities (anaemia, heart disease, chronic kidney disease, oral anticoagulant usage) were recorded. The recorded information also included the type of procedure undergone by each patient. Intra-operative tranexamic acid injections were administered to all patients. Results Male patients accounted for 24% (11) and females for 76% (34). The average age was 82.3 years (range: 73-94). In terms of fracture type, 60% (27) were intracapsular and 40% (18) were extracapsular. Iron deficiency anaemia was present in 24% (11), oral anticoagulants in 20% (9), and systemic malignancy in 12% (6) of patients. The mean post-operative hemoglobin level during endoscopy referral was 7.3 g/dL. Endoscopy revealed normal findings in 60% (27), esophagitis/gastritis in 20% (8), and hiatus hernia in 16% (7) of patients. No patients were diagnosed with active gastrointestinal bleeding or malignancy as the cause of post-operative hemoglobin drop. Conclusion The study did not show evidence of any gastrointestinal bleeding in patients with resistant and refractory post-operative anaemia following fractured neck of femur surgery using endoscopy procedure.The value of such difficult, expensive and time-consuming procedure may be reviewed further.

Comparison of the Analgesic Effect of Pericapsular Ultrasound-Guided Nerve Group Block and Fascia Iliaca Block in Patients with Femoral Head Fracture for Neuraxial Block: A Pilot Study

Background: Pelvic fractures are associated with a lot of pain. Objectives: This study aimed to compare pericapsular nerve and fascia iliaca block analgesia in the positioning of patients with femoral neck fractures for neuraxial anesthesia. Methods: In this double-blind clinical trial study, 50 patients (each group as a pilot: 25 patients) who were candidates for femoral neck fracture surgery were referred to Imam Khomeini Hospital in Urmia. They were randomly assigned (using random allocation software) to 2 groups, including pericapsular block and fascia iliaca block. Visual Analogue Scale (VAS) was used to evaluate analgesia. The pain level of the patients was checked before the block, 10 minutes after the block, and before positioning for neuraxial anesthesia. Results: Regarding gender, 38% (N = 19) were female, and 62% (N = 31) were male. The mean age of the patients was 57.38 ± 8.49 years without a significant difference between the 2 groups (P = 0.315). The mean body mass index of the patients was 26.44 ± 3.77 kg/m2 without a significant difference between the 2 groups (P = 0.243). The mean pain 10 minutes after the block was 1.72 ± 0.73 in the pericapsular group and 3.92 ± 0.86 in the fascia iliaca group (P &lt; 0.001). The mean difference in pain was investigated before and after the block in the pericapsular and fascia iliaca groups (P &lt; 0.001). Ten minutes after the block, the pain intensity was different in the pericapsular group and in the fascia iliaca. Moreover, there was no pain in the moderate classification in the pericapsular treatment group, while 16 patients (64%) had moderate pain in the fascia iliaca group. The differences were statistically significant (P &lt; 0.001). Conclusions: This study shows that the pericapsular block may provide better analgesia for positioning in comparison to the fascia iliaca block in patients with femoral neck fractures.

Comparison of clinical outcomes between posterolateral approach and modified Hardinge approach in salvage total hip arthroplasty after medial buttress plate failure for femoral neck fractures.

The purpose of this study was to investigate the clinical outcomes of salvage total hip arthroplasty (THA) after medial buttress plate surgery for femoral neck fractures via the modified Hardinge approach (MHA) and posterolateral approach (PLA) through a retrospective analysis. From October 2016 to October 2020, a total of 41 patients with failed femoral neck fractures treated with cannulated screws and medial buttress plates underwent unilateral salvage THA, and a retrospective study was conducted. According to the surgical approach, patients were divided into PLA group and MHA group. Clinical and radiological data were evaluated. The primary outcome indicators were the Pain Visual Analog Scale (VAS) and Hip Harris Score (HHS). Secondary outcome indicators include hemoglobin (HGB), hematocrit (HCT), creatine kinase (CK), creatine kinase-MB (CK-MB), etc. The occurrence of postoperative complications was also recorded. There were no differences in demographic or clinical characteristics before surgery. There were no differences in postoperative HGB, HCT, CK-MB and radiological parameters. The surgical approach had no effect on the hospitalization period. The PLA group had earlier ambulation time, and the serum level of CK was also low. Analysis of the HHS and VAS showed that on postoperative day 3, the PLA group had superior scores. The incidence of complications did not significantly differ between groups. The posterolateral approach for salvage THA provides better functional recovery with less muscle damage in the early postoperative period.

Prediction of hip joint function and analysis of risk factors for internal fixation failure after Femoral Neck System (FNS)

ObjectiveAnalysis of the risk factors affecting hip function and complications after femoral neck system (FNS) surgery for femoral neck fractures is of great significance for improving the procedure’s efficacy.MethodsThe data of patients with femoral neck fractures who underwent FNS surgery in our hospital between October 2019 and October 2020 were retrospectively analyzed. Age, gender, time from injury to operation, fracture classification, operation time, fracture reduction, and postoperative weight-bearing time information were set as potential factors that may affect the results. Hip Harris scores were performed at 12 months postoperatively, and postoperative complication data (e.g., femoral head necrosis, nonunion, and femoral neck shortness) were collected. The risk factors affecting hip function and complications after FNS surgery were predicted using linear and logistic regression analyses.ResultsA total of 69 cases of femoral neck fracture were included, with an average age of 56.09 ± 11.50 years. The linear analysis demonstrated that the age and fracture type of the patients were the risk factors affecting the Harris score of the hip joint after FNS surgery. Older patients with displaced femoral neck fractures had an inferior postoperative hip function. In addition, fracture type, reduction of the femoral neck, and postoperative weight-bearing significantly impacted postoperative complications. Displaced fractures, negative fixation, and premature weight-bearing (< 6 weeks) were risk factors for postoperative complications. The Harris score of patients with a shortened femoral neck in the included cases was not significantly different from that of patients without shortening (P = 0.25).ConclusionsAdvanced age and fracture type are important evaluation indicators of the Harris score after FNS internal fixation of femoral neck fractures in young patients. Fracture type, fracture reduction, and postoperative weight-bearing time are risk factors for complications after FNS.

IRON NOF trial: IV iron for anaemic patients with femoral fracture

BackgroundPreoperative anaemia is associated with increased use of blood transfusions, a greater risk of postoperative complications, and patient morbidity. The IRON NOF trial aimed to investigate whether the administration of i.v. iron in anaemic patients during hip fracture surgery reduced the need for blood transfusion and improved patient outcomes. MethodsThis phase III double-blind, randomised, placebo-controlled trial included patients >60 yr old with preoperative anaemia undergoing surgery for femoral neck or subtrochanteric fracture across seven Australian Hospitals. Patients were randomly allocated on a 1:1 basis to receive either i.v. iron carboxymaltose 1000 mg or placebo (saline) at operation. The primary endpoint was blood transfusion use, with secondary endpoints of haemoglobin concentration at 6 weeks, length of hospital stay, rehabilitation duration to discharge, and 6-month mortality. Subgroup analysis compared outcomes in patients <80 yr old and patients >80 yr old. All analyses were performed by intention-to-treat. This trial was terminated early because of jurisdictional changes of more restrictive transfusion practices and changes in consent requirements. ResultsParticipants (n=143) were recruited between February 2013 and May 2017. There was no difference observed in the incidence of blood transfusion between the treatment group (18/70) (26%) compared with the placebo group (27/73) (37%) (odds ratio for transfusion if receiving placebo: 1.70; 95% confidence interval [CI] 0.83–3.47; P=0.15) and there was no overall difference in the median number of blood units transfused between groups (odds ratio 1.52; 95% CI 0.77–3.00; P=0.22). Patients receiving i.v. iron had a higher haemoglobin 6 weeks after intervention compared with the placebo group (Hb 116 g L−1vs 108 g L−1; P=0.01). No difference was observed in length of hospital stay, rehabilitation duration to discharge, or 6-month mortality. However, in younger patients without major bleeding, the use of placebo compared with i.v. iron was associated with an increased number of units of blood transfused (placebo transfusion incidence rate ratio 3.88; 95% CI 1.16–13.0; P=0.03). ConclusionsIn anaemic patients undergoing surgery for hip fracture, i.v. iron did not reduce the overall proportion of patients receiving blood transfusion. The use of i.v. iron may reduce the amount of blood transfused in younger patients. The use of i.v. iron is associated with increased haemoglobin concentrations 6 weeks after the operation.

A meta-analysis comparing the effects of cemented and uncemented prostheses on wound infection and pain in patients with femoral neck fractures.

To providing evidence-based recommendations for surgery in patients with femoral neck fractures, a meta-analysis was conducted to comprehensively evaluate the effects of cemented and uncemented prostheses on postoperative surgical site wound infection and pain in these patients. Relevant studies on the use of cemented prostheses in femoral neck fractures were retrieved from PubMed, EMBASE, Cochrane Library, Ovid, CNKI, and Wanfang databases from the time of their establishment until March 2023. Two authors independently screened and extracted data from the included and excluded literature according to predetermined criteria. Review Manager 5.4 software was used to perform meta-analyses on the collected data. A total of 27 articles comprising 34 210 patients (24 646 cases in the cemented group and 9564 cases in the uncemented group) were included in the final analysis. The results of the meta-analysis showed that, compared with the uncemented group, cemented prostheses significantly reduced the incidence of surgical site wound infections (odds ratio [OR]: 0.75, 95% confidence interval [CI]: 0.64-0.88, p < 0.001) and relieved surgical site wound pain (standardised mean difference: -0.76, 95% CI: -1.12-0.40, p < 0.001), but did not reduce the incidence of pressure ulcers after surgery (OR: 0.50, 95% CI: 0.20-1.26, p = 0.140). Therefore, existing evidence suggests that the use of cemented prostheses in femoral neck fracture surgery can significantly reduce the incidence of surgical site wound infections and relieve surgical site wound pain, which is worthy of clinical recommendation.

Reducing complications of femoral neck fracture management: a retrospective study on the application of multidisciplinary team

BackgroundFemoral neck fractures are associated with substantial morbidity and mortality for older adults. Multi-system medical diseases and complications can lead to long-term care needs, functional decline and death, so patients sustaining hip fractures usually have comorbid conditions that may benefit from application of multidisciplinary team(MDT).MethodsThis is a retrospective cohort study that incorporates medical record review with an outcomes management database. 199 patients were included who had surgery for a new unilateral femoral neck fracture from January 2018 to December 2021 (96 patients in usual care (UC) model and 103 patients in MDT model. High-energy, pathological, old and periprosthetic femoral neck fracture were excluded. Age, gender, comorbidity status, time to surgery, and postoperative complication, length of stay, in-hospital mortality, 30-day readmission rate, 90-day mortality data were collected and analyzed.ResultsPreoperative general data of sex, age, community dwelling and charlson comorbidity score of MDT group (n = 103) have no statistically significant difference with that of usual care (UC) group. Patients treated in the MDT model had significantly shorter times to surgery (38.5 vs. 73.4 h;P = 0.028) and lower lengths of stay (11.5 vs. 15.2 days;P = 0.031). There were no significant differences between two models in In-hospital mortality (1.0% vs. 2.1%; P = 0.273), 30-day readmission rate (7.8% vs. 11.5%; P = 0.352) and 90-day mortality (2.9% vs. 3.1%; P = 0.782). The MDT model had fewer complications overall (16.5% vs. 31.3%; P = 0.039), with significantly lower risks of delirium, postoperative infection, bleeding, cardiac complication, hypoxia, and thromboembolism.ConclusionApplication of MDT can provide standardized protocols and a total quality management approach, leading to fewer complications for elderly patients with femoral neck fracture.Trial registrationNo.

Do Elevated Serum C-Reactive-Protein Levels Excuse Delayed Surgery for Femoral Neck Fractures?

In elderly patients with femoral neck fractures, preoperative serum C-reactive protein (CRP) values might be elevated due to active infections. Although there are limited data on CRP as a predictor of periprosthetic joint infection (PJI), out of concern, this could lead to delayed surgery. Therefore, we aim to investigate whether elevated serum-CRP levels justify delayed surgery for femoral neck fractures. A retrospective analysis was performed of the records of patients undergoing arthroplasty who were found to have an elevated CRP level of 5 mg/dL or more between January 2011 to December 2020. The patients were stratified to three groups, according to initial serum CRP levels at a cut off of 5 mg/dL and the time between admission and surgery (<48 vs. ≥48 h after admission). This study revealed that the patients with elevated serum CRP levels and delayed surgery showed a worse survival rate and significantly more postoperative complications than the patients on whom surgery was performed immediately. There were no significant differences in terms of PJI and prolonged wound healing in the inter-group comparison. Therefore, delays to surgery on the basis of elevated CRP values offer no benefits to patients with femoral neck fractures.

ORTHOPAEDIC SURGICAL DOCUMENTATION: PRE-TEMPLATED OPERATION NOTES SIGNIFICANTLY IMPROVE DOCUMENTATION OF SURGICAL PROCEDURES

The Royal College of Surgeons of England (RCS) Good Surgical Practice guidance identifies essential criteria for surgical operation note documentation. The current quality improvement project aims to identify if using pre-templated operation notes for documenting fractured neck of femur surgery results in improved documentation when compared to free hand orthopaedic operation notes.A total of fourteen categories were identified from the RCS guidance as required across all the operations identified in this study. All operations for the month of October 2021 were identified and the operation notes analysed. Pre-templated operation notes were compared to free hand operation notes.97 cases were identified, of which 74 were free hand operation notes and 23 were pre-templated fractured neck of femur operation notes. All fourteen categories were completed in 13 (57%) of the templated operation notes vs 0 (0%) in the free hand operation notes (odds ratio 0.0052, 95% CI 0.0003 to 0.0945, p &lt; 0.001). The median total number of completed categories was significantly higher in the templated op-note group compared to the free hand op-note group (templated median 14, range 12-14, vs. free hand median 11, range 9 to 13, p &lt; 0.001). Logistic regression analysis of operation notes written by Registrars or Consultants identified Registrars as more likely to document the antibiotic prophylaxis given (p = 0.025).Use of pre-templated operation notes results in significantly improved documentation. Adoption of generic pre-templated operation notes to improve surgical documentation should be considered across all operations.

Intercontinental validation of a clinical prediction model for predicting 90-day and 2-year mortality in an Israeli cohort of 2033 patients with a femoral neck fracture aged 65 or above

PurposeMortality prediction in elderly femoral neck fracture patients is valuable in treatment decision-making. A previously developed and internally validated clinical prediction model shows promise in identifying patients at risk of 90-day and 2-year mortality. Validation in an independent cohort is required to assess the generalizability; especially in geographically distinct regions. Therefore we questioned, is the SORG Orthopaedic Research Group (SORG) femoral neck fracture mortality algorithm externally valid in an Israeli cohort to predict 90-day and 2-year mortality?MethodsWe previously developed a prediction model in 2022 for estimating the risk of mortality in femoral neck fracture patients using a multicenter institutional cohort of 2,478 patients from the USA. The model included the following input variables that are available on clinical admission: age, male gender, creatinine level, absolute neutrophil, hemoglobin level, international normalized ratio (INR), congestive heart failure (CHF), displaced fracture, hemiplegia, chronic obstructive pulmonary disease (COPD), history of cerebrovascular accident (CVA) and beta-blocker use. To assess the generalizability, we used an intercontinental institutional cohort from the Sheba Medical Center in Israel (level I trauma center), queried between June 2008 and February 2022. Generalizability of the model was assessed using discrimination, calibration, Brier score, and decision curve analysis.ResultsThe validation cohort included 2,033 patients, aged 65 years or above, that underwent femoral neck fracture surgery. Most patients were female 64.8% (n = 1317), the median age was 81 years (interquartile range = 75–86), and 80.4% (n = 1635) patients sustained a displaced fracture (Garden III/IV). The 90-day mortality was 9.4% (n = 190) and 2-year mortality was 30.0% (n = 610). Despite numerous baseline differences, the model performed acceptably to the validation cohort on discrimination (c-statistic 0.67 for 90-day, 0.67 for 2-year), calibration, Brier score, and decision curve analysis.ConclusionsThe previously developed SORG femoral neck fracture mortality algorithm demonstrated good performance in an independent intercontinental population. Current iteration should not be relied on for patient care, though suggesting potential utility in assessing patients at low risk for 90-day or 2-year mortality. Further studies should evaluate this tool in a prospective setting and evaluate its feasibility and efficacy in clinical practice.

Total hip arthroplasty reduces the risk of dislocation after femoral neck fracture

IntroductionFemoral neck fracture in the elderly patient can either be managed using hemi-arthroplasty (HA) or total hip arthroplasty (THA). The aim of this study was to explore the rate of three selected complications in each procedure: is the dislocation rate higher with HA compared to THA? Is the blood transfusion rate higher with THA compared to HA? Do the patients who underwent THA require more ICU transfer than the patients who underwent HA? Is the ICU transfer correlated to the use of cement for stem fixation? MethodBased on a national health-care database, a comparative and retrospective study was conducted. 96,184 patients were included after having a surgery for femoral neck fracture between 2014 and 2017. The mean follow up was 3.5 years (Min. 2 years–Max. 5 years). The population was divided into two groups: hemiarthroplasty (HA) and total hip arthroplasty (THA). The primary outcome was the dislocation rate and the secondary outcomes were the blood transfusion rate and the need for ICU after surgery. ResultsAt two years of follow up in the Hemiarthroplasty group, 3647 patients had a dislocation episode over 64,106 patients: 5.69%. In the Total Hip Arthroplasty group: 1904 patients had a dislocation episode over 32,078 patients: 5.94% (p=0.26711). The percentage of deceased patient without dislocation was 17.76% in the HA group and 11.56% in the THA group (p<0.001). The univariate hazard ratio for dislocation was higher in the THA group: HR 1.063 IC 95% (0.993–1.138) p=0.077. The multivariate analysis calculating competitive risk with death and dislocation found THA to be a protective factor of dislocation HR 0.926 IC 95% (0.866–0.991) p=0.0266. The rate of blood transfusion was 5.59% in the THA group and 7.03% in the HA group (p<0.001), The multivariate analysis found HR=1.062 IC 95% (0.99–1.139) p=0.0955. The need for ICU transfer after the surgery was 7.04% in the HA group and 8.08% in the THA group (p<0.001). The multivariate analysis found HR 0.995 IC 95% (0.921–1.076) p=0.9094. Finally, only cement was found as an independent risk factor of ICU transfer after surgery: HR 1.254 IC 95% (1.164–1.35) p<0.0001. ConclusionTHA for femoral neck fracture allows to reduce the risk of dislocation compared to hemiarthroplasty. The multivariate analysis failed to prove the superiority of one procedure over the other regarding blood transfusion risk and the need for ICU transfer. The use of cemented stem appears to be a risk factor of ICU transfer after hip arthroplasty. Level of evidenceIII, Retrospective comparative study.
