Bipolar hip arthroplasty using conjoined tendon preserving posterior lateral approach in treatment of displaced femoral neck fractures

BACKGROUND Hip fractures account for 23.8%of all fractures in patients over the age of 75 years.More than half of these patients are older than 80 years.Bipolar hemiarthroplasty(BHA)was established as an effective management option for these patients.Various approaches can be used for the BHA procedure.However,there is a high risk of postoperative dislocation.The conjoined tendon-preserving posterior(CPP)lateral approach was introduced to reduce postoperative dislocation rates.AIM To evaluate the effectiveness and safety of the CPP lateral approach for BHA in elderly patients.METHODS We retrospectively analyzed medical data from 80 patients with displaced femoral neck fractures who underwent BHA.The patients were followed up for at least 1 year.Among the 80 patients,57(71.3%)were female.The time to operation averaged 2.3 d(range:1-5 d).The mean age was 80.5 years(range:67-90 years),and the mean body mass index was 24.9 kg/m^(2)(range:17-36 kg/m^(2)).According to the Garden classification,42.5%of patients were typeⅢand 57.5%of patients were typeⅣ.Uncemented bipolar hip prostheses were used for all patients.Torn conjoined tendons,dislocations,and adverse complications during and after surgery were recorded.RESULTS The mean postoperative follow-up time was 15.3 months(range:12-18 months).The average surgery time was 52 min(range:40-70 min)with an average blood loss of 120 mL(range:80-320 mL).The transfusion rate was 10%(8 of 80 patients).The gemellus inferior was torn in 4 patients(5%),while it was difficult to identify in 2 patients(2.5%)during surgery.The posterior capsule was punctured by the fractured femoral neck in 3 patients,but the conjoined tendon and the piriformis tendon remained intact.No patients had stem varus greater than 3 degrees or femoral fracture.There were no patients with stem subsidence more than 5 mm at the last follow-up.No postoperative dislocations were observed throughout the follow-up period.No significance was found between preoperative and postoperative mean Health Service System scores(87.30±2.98 vs 86.10±6.10,t=1.89,P=0.063).CONCLUSION The CPP lateral approach can effectively reduce the incidence of postoperative dislocation without increasing perioperative complications.For surgeons familiar with the posterior lateral approach,there is no need for additional surgical instruments,and it does not increase surgical difficulty.

Relationship between preoperative psychological stress and shortterm prognosis in elderly patients with femoral neck fracture

BACKGROUND Older adults are at high risk of femoral neck fractures(FNFs).Elderly patients face and adapt to significant psychological burdens,resulting in different degrees of psychological stress response.Total hip replacement is the preferred treatment for FNF in elderly patients;however,some patients have poor postoperative prognoses,and the underlying mechanism is unknown.We speculated that the postoperative prognosis of elderly patients with FNF may be related to preoperative psychological stress.AIM To explore the relationship between preoperative psychological stress and the short-term prognosis of elderly patients with FNF.METHODS In this retrospective analysis,the baseline data,preoperative 90-item Symptom Checklist score,and Harris score within 6 months of surgery of 120 elderly patients with FNF who underwent total hip arthroplasty were collected.We analyzed the indicators of poor short-term postoperative prognosis and the ability of the indicators to predict poor prognosis and compared the correlation between the indicators and the Harris score.RESULTS Anxiety,depression,garden classification of FNF,cause of fracture,FNF reduction quality,and length of hospital stay were independent influencing factors for poor short-term postoperative prognoses in elderly patients with FNF(P<0.05).The areas under the curve for anxiety,depression,and length of hospital stay were 0.742,0.854,and 0.749,respectively.The sensitivities of anxiety,depression,garden classification of FNF,and prediction of the cause of fracture were 0.857,0.786,0.821,and 0.821,respectively.The specificities of depression,FNF quality reduction,and length of hospital stay were the highest at 0.880,0.783,and 0.761,respectively.Anxiety,depression,and somatization scores correlated moderately with Harris scores(r=-0.523,-0.625,and-0.554;all P<0.001).CONCLUSION Preoperative anxiety,depression,and somatization are correlated with poor short-term prognosis in elderly patients with FNF and warrant consideration.

Comparison of DAA and PLA Approaches for Total Hip Replacement in the Treatment of Femoral Neck Fractures

Objectives: Femoral neck fractures are becoming more common within nowadays. This research is to explore the clinical effect of primary total hip replacement (THA) via direct anterior approach (DAA) and posterolateral approach (PLA) in the treatment of femoral neck fracture. Methods: Retrospective analysis of 100 cases of elderly patients with femoral neck fracture who underwent total hip arthroplasty admitted to Tianyou Hospital affiliated to Wuhan University of Science and Technology from January 2019 to January 2022. 50 patients treated with DAA approach were included in the observation group, and 50 patients treated with PLA approach were included in the control group. The operation indexes, postoperative acetabular abduction angle and anteversion angle, hip joint function, Harris score and complications were compared between the two groups. Result: The length of incision in the observation group was shorter than that in the control group, and the amount of intraoperative bleeding and postoperative hospital stay were shorter than those in the control group (P < 0.05);There was a statistically significant difference between the two groups in the ratio of acetabular abduction angle and its safe zone, and the length difference of both lower limbs (P < 0.05), while there was no statistically significant difference between the two groups in the ratio of acetabular anteversion angle and its safe zone, eccentricity, and its recovery rate (P > 0.05);Harris score of hip joint: 6 months after operation, the anterior approach group was significantly higher than the posterolateral approach group (P < 0.05), and there was no statistical difference between the two groups 12 months after operation (P > 0.05);The total incidence of complications in the observation group was lower than that in the control group, with a statistically significant difference (P Conclusion: DAA and PLA approaches for total hip replacement can restore the hip joint structure of patients with femoral neck fractures and achieve good results, but DAA approach has greater advantages in early postoperative recovery, improvement of hip joint function, small surgical injury, high application value, so it is recommended.

Comparison of femoral neck fracture healing and affected limb pain after anterolateral-approach minimally invasive total hip replacement and hemiarthroplasty

Objective:To study the differences in femoral neck fracture healing and affected limb pain after anterolateral-approach minimally invasive total hip replacement and hemiarthroplasty. Methods:A total of 92 patients with femoral neck fracture who received hip replacement in our hospital between May 2013 and December 2015 were selected and randomly divided into total hip and half hip group, total hip group received anterolateral-approach minimally invasive total hip replacement, half hip group received anterolateral-approach minimally invasive hemiarthroplasty, and 1 month after operation, serum was collected to detect the levels of bone metabolism markers, osteocyte cytokines, SP and CGRP.Results:1 month after operation, serum PINP, PICP, BMP, TGF-β, FGF, IGF-I and IGF-II levels of total hip group were significantly higher than those of half hip group while TRAP5b and CatK levels were significantly lower than those of half hip group;the day after operation, serum pain media SP and CGRP levels were not significantly different between the two groups of patients;36 h after operation, serum SP and CGRP levels of total hip group were significantly lower than those of half hip group.Conclusion:The bone metabolism after anterolateral-approach minimally invasive total hip replacement is better than that after hemiarthroplasty, and the degree of pain is less than that after hemiarthroplasty.

Effect of different hip replacement methods under minimally invasive anterolateral approach on bone metabolism and joint pain in patients with femoral neck fracture

Objective: To explore the effect of different hip replacement methods under minimally invasive anterolateral approach on bone metabolism and joint pain in patients with femoral neck fracture. Methods: A total of 110 patients with femoral neck fracture who were treated in Ruijin Hospital North, Shanghai Jiaotong University School of Medicine between July 2015 and January 2017 were collected and divided into control group and observation group by random number table, each with 55 cases. Control group accepted half hip replacement under minimally invasive anterolateral approach, and observation group accepted total hip replacement under minimally invasive anterolateral approach. The differences in contents of bone metabolism and joint pain-related indexes were compared between the two groups before and after surgery. Results: Before surgery, serum contents of bone formation indexes, bone resorption indexes, inflammatory indexes and pain mediators were not statistically significant between the two groups. 1 month after surgery, serum bone formation indexes PINP, BAP and BGP contents of observation group were higher than those of control group;serum bone resorption indexes β-CTX and TRACP-5b contents were lower than those of control group;serum inflammatory indexes IL-1 and TNF-α contents were lower than those of control group;serum pain mediators 5-HT and PGE2 contents were lower than those of control group. Conclusion: Total hip replacement under minimally invasive anterolateral approach is more effective to promote the formation of bone formation/bone resorption balance and reduce the joint pain.

Effect of early surgery in high surgical risk geriatric patients with femoral neck fracture and taking antiplatelet agents

AIM: To investigate the effect of early surgical intervention on the high surgical risk elderly patients who sustained femoral neck fracture(FNF) and taking concomitant antiplatelet agents. METHODS: Between 2010 and 2012, a prospective study was conducted on 49 geriatric patients, who took antiplatelet agents, sustained FNF and underwent surgery within 72 h [early surgery(ES) group], and these were compared with a retrospective consecutive case series of patients with similar characteristics(45 cases) who had delayed surgery(DS group) after 72 h during an earlier 3-year period. Postoperative outcomeswere followed for one year and compared. RESULTS: There were non-significant differences in perioperative blood loss, blood transfusion, intensive care unit requirement and postoperative mortality(P > 0.05 all). There were 2 patients(4%) in the DS group who died after surgery(P = 0.23). However, the ES group showed a significantly better postoperative outcome in terms of postoperative complications, length of hospital stay, and functional outcome(P < 0.05 all).CONCLUSION: Early hip surgery in geriatric hip fracture patients with ongoing antiplatelet treatment was not associated with a significant increase of perioperative blood loss and postoperative mortality. Moreover, ES resulted in a better postoperative surgical outcome. In early hip surgery protocol, the antiplatelet agents are discontinued and the patient is operated on within 72 h after admission, which is safe and effective for the medically fit patients.

Hip hemi-arthroplasty for neck of femur fracture:What is the current evidence?

This editorial reviews and summarises the current evidence(meta-analyses and Cochrane reviews) relating to the use of hip hemi-arthroplasty for neck of femur fractures. Regarding the optimal surgical approach,two recent meta-analyses have found that posterior approaches are associated with: higher rates of dislocation compared to lateral and anterior approaches; and higher rates of re-operation compared to lateral approaches. Posterior approaches should therefore be avoided when performing hip hemi-arthroplasty procedures. Assessing the optimal prosthesis head component,three recent meta-analyses and one Cochrane review have found that while unipolar hemiarthroplasty can be associated with increased rates of acetabular erosion at short-term follow-up(up to 1 year),there is no significant difference between the unipolar hemi-arthroplasty and bipolar hemi-arthroplasty for surgical outcome,complication profile,functional outcome and acetabular erosion rates at longer-term follow-up(2 to 4 years). With bipolar hemi-arthroplasty being the more expensive prosthesis,unipolar hemi-arthroplasty is the recommended option. With regards to the optimal femoral stem insertion technique,three recent metaanalyses and one Cochrane Review have found that,while cemented hip hemi-arthroplasties are associated with a longer operative time compared to uncemented Hip Hemi-arthroplasties,cemented prostheses have lower rates of implant-related complications(particularly peri-prosthetic femoral fracture) and improved postoperative outcome regarding residual thigh pain and mobility. With no significant difference found between the two techniques for medical complications and mortality,cemented hip hemi-arthroplasty would appear to be the superior technique. On the topic of wound closure,one recent meta-analysis has found that,while staples can result in a quicker closure time,there is no significant difference in post-operative infections rates or wound healing outcomes when comparing staples to sutures. Therefore,either suture or staple wound closure techniques appear equally appropriate for hip hemiarthroplasty procedures.

Tissue Sparing Surgery and Its Relevance within Hip Prosthesis

The total hip replacement rationale, since 1960 when it was introduced by Sir Charnley, has been modified and evolved until nowadays thanks to laboratory research and clinical trials. This evolution followed a guideline whose milestones are: 1) the surgical approach and implantation technique (ex: detachment of the greater trochanter);2) to use or not to use cement;3) the evolution of materials (titanium, ceramic, x-linked polyethylene);4) the identification of the debris-disease rather than the cement-disease;5) studies focused on bone-prosthesis interaction and biological phenomena related. Between those studies, the authors consider crucial the introduction of tissue sparing surgery and femoral neck preserving rationale, concepts to which they have devoted their scientific research and clinical experience for over the last 30 years, from 1980 to nowadays.

Effect of dynamic hip system blade on the treatment of femoral neck fractures in elderly patients with osteoporosis

Objective：To discuss the curative effect of the dynamic hip system blade （DHS-blade） on the treatment of femoral neck fractures in elderly patients with osteoporosis.Methods：A retrospective study was conducted to analyse the clinical data of 60 elderly patients with osteoporosis who had been treated for femoral neck fractures with DHS-blade in our department between September 2012 and February 2014.There were 22 males and 38 females with a mean age of （66.8±3.2） years.According to the Singh Index Classification,all the patients＇ Singh index was below level 3.The Harris criterion and function recovery after operation were analysed.Results：All patients were followed up for 12-17 months （mean 14 months）.No femoral head necrosis,femoral neck shortening,internal fixation loosening or backing out of the nails occurred.Bone nonunion was found in one case and he had a good recovery after total hip arthroplasty.The time for fracture healing ranged from 3-6 months （average 3.5 months）.According to Harris criterion,35 cases were rated as excellent,22 good,2 fair and 1 poor.The Harris scale was significantly improved from 28.46±2.35 preoperatively to 91.98±3.26 at 6 months postoperatively （P＜0.05）.Conclusion：DHS-blade,being minimally invasive,allowing earlier postoperative exercise and avoiding the complications elicited by traditional internal fixation,is advisable for treatment of femoral neck fractured patients with osteoporosis.

Comparative study of anterolateral approach versus posterior approach for total hip replacement in the treatment of femoral neck fractures in elderly patients

Objective： To compare the clinical outcome of anterolateral minimally invasive approach versus conventional posterior approach for total hip replacement against femoral neck fractures in elderly patients. Methods： The retrospective study was carried out on 42 patients who suffered from displaced femoral neck fractures （19 cases of Garden type Ⅲ, 23 cases of Garden type Ⅳ） treated by total hip replacement via anterolateral minimally invasive approach or conventional posterior approach by the same experienced surgeon. The average age of the patients was 78.1 years （range： 65-89 years）. They were divided into anterolateral mini-invasive group （22 cases） and posterior group （20 cases）. The mean time of follow-up was 13 months （range： 6-36 months）. The anterolateral approach described by Hardinge goes through between anterior 1/3 and posterior 2/3 of the gluteus medius muscle, reaching the femoral neck from anterior capsule. The traditional posterior approach described by Moore （Southern incision） goes through the insertions of short external rotation muscles, reaching the femoral neck from posterior capsule. The related variables under observation were length of incision, operation time, postoperative limp, length of hospital stay and bed stay and dislolcation rate. Results： The length of the skin incision varied between 7 cm and 12 cm with the anterolateral minimally invasive technique, compared to 15-22 cm in the conventional procedure. It took less time （average 15 minutes） to complete the anterolateral minimally invasive approach （72 15 min）, compared with the conventional approach （87 min ±10 min）. The average Harris hip score was 91.23±10.20 in anterolateral approach, 90.03±11.05 in the posterior approach. The average length of hospital stay for patients with the anterolateral approach was （6.4±2.2） days （range： 4-9 days）, while that in posterior approach was （9.2 ±3.1） days （range： 6-13 days）. The average length of bed stay was （3.4±1.1） days （range： 2-5 days） in anterolateral group and （6.2±2.8） days （range： 3-10 days） in posterior group. No patients in anterolateral group experienced dislocation. One （5%） hip in posterior approach had dislocation. Conclusions： Anterolateral mini-invasive approach can decrease trauma, operation time, length of hospital stay and bed stay and rehabilitation time. The stability and minimal muscular damage permit the acceleration of postoperative rehabilitation, which can subsequently reduce the perioperative risk in the treatment of femoral neck fractures in the elderly undergoing total hip replacement.

Multiple stress fractures of unilateral femur:A case report

BACKGROUND Stress fractures of the femoral neck are not common in clinical practice,and simultaneous stress fractures of the femoral neck and proximal femur of the unilateral femur are even more rare.We introduce a case of this type of fracture that was treated in our department,analyze the causes,and review similar stress fractures reported in the literature to provide references for the diagnosis and treatment of such conditions.CASE SUMMARY A 62-year-old female,with a free medical history,was admitted to the hospital mainly due to pain in the right hip and worsening pain in the right thigh.The patient had no obvious history of trauma.X-ray and computed tomography showed fracture of the femoral neck and proximal femur.The patient had undergone surgery 1 year prior to address a fracture of the left proximal femur that had occurred in a traffic accident.Our first consideration was stress fracture of the femoral neck;however,simultaneous stress fractures of the femoral neck and proximal femur of the unilateral femur were seen.The femoral neck stress fracture was a tension fracture,with obvious displacement and varus deformity of the hip.Considering that the patient was an elderly female,we performed total hip arthroplasty.Follow-up X-rays showed that the stress fracture of the proximal femur had mostly healed after 3 mo.CONCLUSION Muscle fatigue and hip varus deformity provide an anatomical basis for the occurrence of femoral neck stress fractures.

目的:探讨量化康复训练配合循证护理模式在股骨颈骨折患者中的应用效果。方法:选取2023年1—12月厦门大学附属第一医院收治的120例股骨颈骨折患者,按随机数字表法分两组,各60例。对照组行常规护理,观察组行量化康复训练配合循证护理模式。比较两组疼痛程度、心理状态、训练依从性、并发症发生率、髋关节功能、生活质量。结果:干预后,观察组视觉模拟评分法(VAS)、焦虑自评量表(SAS)、抑郁自评量表(SDS)评分均低于对照组,训练依从性高于对照组,并发症发生率低于对照组,Harris髋关节功能评分(HHS)、世界卫生组织生存质量量表(WHOQOL-100)评分均高于对照组,差异均有统计学意义(P<0.05)。结论:量化康复训练配合循证护理模式可以减轻股骨颈骨折患者疼痛程度与不良情绪,改善髋关节功能,减少并发症的发生,提升患者生活质量。

老年股骨颈骨折患者髋关节置换术后手术部位感染的危险因素分析

目的 评估老年股骨颈骨折患者行髋关节置换术后手术部位感染的危险因素,为有效地预防老年股骨颈骨折术后手术部位感染提供参考依据。方法 选取漯河医学高等专科学校第二附属医院2018年1月-2023年3月收治的老年股骨颈骨折患者350例,均行髋关节置换手术治疗,根据术后手术部位感染情况分为感染组22例,未感染组328例;比较2组患者的一般情况、手术方式、手术时间、基础疾病,归纳老年股骨颈骨折患者术后手术部位感染的影响因素。结果 高龄(>80岁)、肥胖、低蛋白血症和糖尿病是老年髋部骨折患者术后感染的危险因素(P<0.05)。结论 高龄、肥胖、低蛋白血症和基础疾病是老年股骨颈骨折患者术后手术部位感染的危险因素,应加强相关监管;对于怀疑手术部位感染的患者,应积极送检病原菌培养,重视真菌及分枝杆菌可提高病原菌检出率。
