Cementless Bipolar Hemiarthroplasty for Unstable Intertrochanteric Fractures in Elderly Patients

Background

Bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients is a viable option that can prevent the complications of an open reduction, such as nonunion and metal failure. This study evaluated the clinicoradiological results of cementless bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients.

Methods

Forty hips were followed for more than 2 years after cementless bipolar hemiarthroplasty using a Porocoat® AML Hip System. The mean age was 78.8 years and the mean follow-up period was 40.5 months. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using a range of indices.

Results

At the last follow-up, the mean Harris hip score was 80.6 points. There were one case of hip pain and one case of thigh pain. Twenty-four cases (60%) showed no decrease in ambulation capacity postoperatively. Radiologically, there were 23 cases (57.5%) of fixation by bone ingrowth and 17 cases (42.5%) of stable fibrous fixation. There were no cases of osteolysis. Eleven cases (27.5%) of new bone formation were found around the stem. All stems were stable without significant changes in alignment or progressive subsidence.

Conclusions

The short-term results of cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures were satisfactory.     

Cemented bipolar hemiarthroplasty with a cerclage cable technique for unstable intertrochanteric hip fractures in elderly patients

Aim

The purpose of this study is to evaluate the clinical and radiological outcomes of cemented bipolar arthroplasty as a primary treatment for unstable intertrochanteric fracture in the elderly patients.

Methods

Twenty hips with unstable intertrochanteric fractures were followed for more than 2 years after cemented bipolar hemiarthroplasty. The mean age was 69 years, and the mean follow-up period was 30.5 months. We evaluated the results by Harris hip score, complications, and radiologic findings.

Results

At the last follow-up, the mean Harris hip score was 83.3 points. Radiologically, there was no case of osteolysis. All stems were stable without significant changes in alignment or progressive subsidence.

Conclusions

Bipolar hemiarthroplasty with calcar reconstruction is a good option for unstable intertrochanteric fractures in elderly patients with severe osteoporosis with strict indication selection. Longer-term studies with larger numbers of patients are required to address the issues of late complications.     

Intertrochanteric fractures in elderly high risk patients treated with Ender nails and compression screw

Background:

Ender and Simon Weidner popularized the concept of closed condylocephlic nailing for intertrochanteric fractures in 1970. The clinical experience of authors revealed that Ender nailing alone cannot provide secure fixation in elderly patients with osteoporosis. Hence we conducted a study to evaluate the efficacy of a combined fixation procedure using Ender nails and a cannulated compression screw for intertrochanteric fractures.

Materials and Methods:

76 patients with intertrochanteric fractures were treated using intramedullary Ender nails and cannulated compression screw from January 2004 to December 2007. The mean age of the patients was 80 years (range 70-105 years).Using the Evan’s system of classification 49 were stable and 27 unstable fractures. Inclusion criteria was high risk elderly patients (age > 70 years) with intertrochanteric fracture. The exclusion criteria included patients with pressure sores over the trochanteric region. Many patients had pre-existing co-morbidities like diabetes mellitus, hypertension, COPD, ischemic heart disease, CVA and coronary artery bypass surgery. The two Ender nails of 4.5mm each were passed across the fracture site into the proximal neck. This was reinforced with a 6.5 mm cannulated compression screw passed from the sub trochanteric region, across the fracture into the head.

Results:

The mean follow-up was 14 months (range 9-19 months) Average time to fracture union was 10 weeks (range 6-16 weeks). The mean knee ROM was 130° (± 5°). There was no case of nail penetration into hip joint. In five cases with advanced osteoporosis there was minimal migration of Ender nails distally.

Conclusions:

The Ender nailing combined with compression screw fixation in cases of intertrochanteric fractures in high risk elderly patients could achieve reliable fracture stability with minimal complications.

Comparison of elderly patients with and without intertrochanteric fractures and the factors affecting fracture severity

BackgroundIntertrochanteric fractures in elderly patients are common and normally caused by low-energy injuries, such as falls. The favored treatment method is closed reduction with internal fixation using plate or nail systems. In general, the severity of an intertrochanteric fracture is one of key factors that affects the success rate of fixation. However, the factors that affect the severity of intertrochanteric fractures in elderly patients are rarely reported in the literature. In this prospective study, several possible factors were investigated.MethodsThe bone mineral densities (BMD) of 48 elderly patients (≥ 65 years) with intertrochanteric fractures due to low-energy injuries were compared with the BMDs of 48 elderly persons without hip fractures. Both groups were composed of people of similar ages and male-to-female ratios. Furthermore, in the patients with fractures, BMD, body mass index (BMI), body weight, and body height were compared between patients with nonsevere (intact lesser trochanter; 14 patients) and severe (displaced lesser trochanter or reverse obliquity fractures; 34 patients) intertrochanteric fractures.ResultsPatients with intertrochanteric fractures had significantly lower BMDs compared with persons without hip fractures to the lesser trochanter, total hip area, femoral neck, or greater trochanter (p = 0.001, <0.001, <0.001, and <0.001, respectively). There was no statistical difference in terms of BMD, BMI, body weight, or body height between patients with nonsevere and severe fractures.ConclusionElderly patients with intertrochanteric fractures have lower BMDs than persons without hip fractures. However, the severity of intertrochanteric fractures cannot be predicted by local BMD, BMI, body weight, or body height.     

Minimally invasive technique versus conventional technique of dynamic hip screws for intertrochanteric femoral fractures

Introduction  

Intertrochanteric fractures of femur are common in elderly patients. The compression hip screw has become the predominant method for osteosynthesis of intertrochanteric fractures. However, the conventional dynamic hip screws (CDHS) technique has some disadvantages. Recently, we have used a minimally invasive dynamic hip screws (MIDHS) technique to reduce these disadvantages. This prospective study is to compare curative effect of MIDHS with that of CDHS with open reduction on Evans type 1 intertrochanteric fractures.     

Mid-Term Survivals After Cementless Bipolar Hemiarthroplasty for Unstable Intertrochanteric Fractures in Elderly Patients

In this study, we aimed to evaluate the results of treatment of intertrochanteric femur fractures fixation with a 95° fixed-angle blade plate in elderly patients.     

Calcar Preservation Arthroplasty for Unstable Intertrochanteric Femoral Fractures in Elderly

Background

The treatment of unstable intertrochanteric fractures in elderly is still controversial. The purpose of this study is to present treatment strategies for unstable intertrochanteric fractures with hemiarthroplasty using standard uncemented collared femoral stems and at the same time preserving the fractured calcar fragment.

Methods

Fifty-four patients aged 75 years or older with unstable intertrochanteric fractures were included in this prospective cohort study. All patients were treated with calcar preserving hemiarthroplasty using cementless collored femoral stems. Fractured calcar fragment was stabilized either by compaction between the implant and femur or fixed with cable grip system. Follow-up evaluations were performed at least 24 months and later. Palmer and Parker mobility score and visual analogue scale (VAS) pain score were assessed. We also analyzed radiographs of the operated hip at each follow-up visit.

Results

The patients were 15 males and 39 females with a mean age of 81.3 years (range, 75 to 93 years). The average operative time was 86.6 minutes. The mean transfused blood units were 1.2 units. The average duration of hospital stay was 5.3 days. The preoperative mean mobility score was 6.20. This score was found to be 4.96 on postoperative third day and 5.90 at 24 months postoperatively. The results of the statistical analysis revealed significant increase in the mobility scores at each follow-up after three days. Radiological interpretation revealed no loosening in the cable-grip systems, and no significant subsidence (> 5 mm) of prosthesis was observed.

Conclusions

Calcar preservation arthroplasty is a good option for elderly patients with severe osteoporosis, frail constitution and the patients who are at higher risk for second operation due to unstable intertrochanteric fractures.     

Comparison of migration behavior between single and dual lag screw implants for intertrochanteric fracture fixation

Background  

Lag screw cut-out failure following fixation of unstable intertrochanteric fractures in osteoporotic bone remains an unsolved challenge. This study tested if resistance to cut-out failure can be improved by using a dual lag screw implant in place of a single lag screw implant. Migration behavior and cut-out resistance of a single and a dual lag screw implant were comparatively evaluated in surrogate specimens using an established laboratory model of hip screw cut-out failure.     

Cemented hip hemiarthroplasty clinical observations on unstable intertrochanteric fracture in elderlies

Objective

To observe the clinical effect of steel cable or greater trochanter reattachment (GTR) device combined with cemented hip hemiarthroplasty for unstable intertrochanteric fracture in elderlies.

Materials and methods

From July 2002 to June 2014, a total of 57 elderly patients with unstable intertrochanteric fracture, including 23 males and 34 females, were treated. Their ages ranged from 80 to 95 years, with the average of 83 years. According to Evans-Jensen classification, there were 18 type IIa cases, 13 type IIb cases and 26 type III cases. All patients received cemented bipolar femoral head replacement, using steel cable or GTR device to stabilize the unstable intertrochanteric fracture.

Results

All patients had successful operation procedure and were followed up for 36 months. Postoperative X-ray revealed satisfying postoperative position of artificial hip joint, without subsidence or loosening. Three cases with the use of steel cable alone to treat greater trochanter fracture suffered from rupture of steel cable. The patients using GTR device showed good reduction at the site of displaced greater trochanter fracture and a firm fixation. The clinical outcome measured with Harris hip score and Barthel Index at the time of final follow-up was significantly different between the groups.

Conclusion

Hip hemiarthroplasty for elderly patients with unstable intertrochanteric fracture can meet the load bearing requirement at early stage and reduce postoperative complications prominently. Moreover, GTR devices can effectively solve the instability problem of posterior-lateral side of hip caused by displacement of greater trochanter in unstable intertrochanteric fracture.

     

Primary hemiarthroplasty for unstable osteoporotic intertrochanteric fractures in the elderly: A retrospective case series

Background:

The management of unstable osteoporotic intertrochantric fractures in elderly is challenging because of difficult anatomical reduction, poor bone quality, and sometimes a need to protect the fracture from stresses of weight bearing. Internal fixation in these cases usually involves prolonged bed rest or limited ambulation, to prevent implant failure secondary to osteoporosis. This might result in higher chances of complications like pulmonary embolism, deep vein thrombosis, pneumonia, and decubitus ulcer. The purpose of this study is to analyze the role of primary hemiarthroplasty in cases of unstable osteoporotic intertrochanteric femur fractures.

Materials and Methods:

We retrospectively analyzed 37 cases of primary hemiarthroplasty performed for osteoporotic unstable intertrochanteric fractures (AO/OTA type 31-A2.2 and 31-A2.3 and Evans type III or IV fractures). There were 27 females and 10 males with a mean age of 77.1 years (range, 62–89 years).

Results:

Two patients died due to unrelated cause (myocardial infarction) within 6 months of surgery and remaining 35 patients were followed up to an average of 24.5 months (range,18–39 months). The average surgery time was 71 min (range, 55–88 min) with an average intraoperative blood loss of 350 ml (range, 175–500 ml). Six patients needed blood transfusion postoperatively. The patients walked on an average 3.2 days after surgery (range, 2–8 days). One patient had superficial skin infection and one had bed sore with no other significant postoperative complications. One patient of Alzheimer’s disease refused to walk and had a poor result. A total of 32 out of 35 patients (91%) had excellent to fair functional results and 2 had poor result with respect to the Harris hip score (mean 84.8±9.72, range 58-97). One patient who had neurological comorbidity refused to walk post operatively and was labeled as failed result.

Conclusion:

Hemiarthroplasty for unstable osteoporotic intertrochanteric fractures in elderly results in early ambulation and good functional results although further prospective randomized trials are required before reaching to conclusion.

目的探讨内固定术和人工关节置换术治疗老年性不稳定型骨质疏松性股骨转子间骨折的临床疗效。方法对43例老年性不稳定型骨质疏松性股骨转子间骨折患者采用内固定术(23例)和人工关节置换术(20例)治疗,并对两种治疗方法的手术时间、术中出血量、并发症发生率、Harris评分及功能恢复评分(FRS)情况进行评估。结果 43例均顺利完成手术。患者均得到随访,时间18～25(20.3±2.3)个月。人工关节置换术组FRS、Harris恢复情况均优于内固定组(P<0.05),并发症发生率低于内固定组(P<0.05)。结论人工关节置换术治疗老年性不稳定型骨质疏松性股骨转子间骨折,疗效优于内固定术。     

Hip arthroplasty in failed intertrochanteric fractures in elderly

Background:

Failed intertrochanteric fractures in elderly patients are surgical challenge with limited options. Hip arthroplasty is a good salvage procedure even though it involves technical issues such as implant removal, bone loss, poor bone quality, trochanteric nonunion and difficulty of surgical exposure.

Materials and Methods:

30 patients of failed intertrochanteric fractures where hip arthroplasty was done between May 2008 and December 2011 were included in study. 13 were males and 17 were females with average age of 67.3 years. There were 2 cemented bipolar arthroplasties, 19 uncemented bipolar, 4 cemented total hip arthroplasty and 5 uncemented total hip arthroplasties. 16 patients had a trochanteric nonunion, which was treated by tension band principles. Total hip was considered where there was acetabular damage due to the penetration of implant.

Results:

The average followup was 20 months (range 6-48 months). Patients were followed up from 6 to 48 months with average followup of 20 months. None of the patients were lost to followup. There was no dislocation. All patients were ambulatory at the final followup.

Conclusion:

A predictable functional outcome can be achieved by hip arthroplasty in elderly patients with failed intertrochanteric fractures. Though technically demanding, properly performed hip arthroplasty can be a good salvage option for this patient group.     

Intramedullary nail versus extramedullary plate fixation for unstable intertrochanteric fractures: decision analysis

Background

The best options of internal fixation for unstable intertrochanteric femoral fractures in elderly osteoporotic patients remain controversial. We determined whether intramedullary nail or extramedullary plate provides better treatment for unstable intertrochanteric fractures using a decision analysis tool that considers quality of life.

Methods

A decision analysis model was constructed containing final outcome score and the probability of mortality within 1 year, infection, and mechanical complications. Final outcome was defined as health-related quality of life and was used as a utility in the decision tree. Probabilities were obtained by literature review, and health-related quality of life was evaluated by asking 30 orthopedic experts to complete a questionnaire. A roll back tool was used to determine the best surgical option, and sensitivity analysis was performed to compensate for decision model uncertainty.

Results

The decision model favored intramedullary nailing in terms of quality of life. In one-way sensitivity analysis, intramedullary nailing was more beneficial than the extramedullary plating, when probability of mechanical complication after intramedullary nailing was below 0.258.

Conclusions

In terms of quality of life, the decision analysis model showed that intramedullary nailing was more beneficial for patients with an unstable intertrochanteric fracture.

Prospective randomised controlled trial of an intramedullary nail versus a sliding hip screw for intertrochanteric fractures of the femur

Purpose

The purpose of this prospective randomised trial was to assess whether an intramedullary nail is superior to a sliding hip screw in the treatment of multifragmentary intertrochanteric fractures

Methods

Eighty patients with a 31-A2.2 or A2.3 Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) intertrochanteric fracture were randomly allocated to fixation with either the Gamma nail or the AMBI sliding hip screw device.

Results

All patients were followed up at one, three, six and 12 months postoperatively, except for nine who died. There was no statistical difference in Parker mobility score between groups. The Gamma nail group had significantly higher Barthel Index and EuroQol-5D (EQ-5D) scores than the AMBI group at 12 months. At the same time, the EQ-5D score had returned to its pre-operative values in the Gamma nail group but not in the AMBI group. There were no differences in mortality, radiation time and hospital stay. Duration of the operation, incision length and hip pain occurrence were significantly less in the Gamma nail group.

Conclusions

Few failures occur when unstable 31-A2.2 and A2.3 AO/OTA fractures are fixed with a sliding hip screw. Nevertheless, an intramedullary nail seems superior in reconstituting patients to their pre-operative state.     

The Efficacy of Suture Fixation of the Greater Trochanter in Unstable Intertrochanteric Fractures

BackgroudIntertrochanteric fractures are one of the most common fractures in the elderly, especially those having osteoporosis. Stable intertrochanteric fractures may be fixed with implants including the dynamic hip screw and proximal femoral nail antirotation; however, this method is difficult to apply to unstable fractures. Bipolar hemiarthroplasty can be applied to unstable fractures and it prevents complications by facilitating early ambulation in the elderly. Many studies reported on how to fix the greater trochanter in unstable fractures during arthroplasty. We suggest that suture fixation alone can be a useful, effective, and affordable method.MethodsWe retrospectively enrolled 294 patients who underwent hemiarthroplasty for an unstable intertrochanteric fracture, and 225 patients were included in this study after excluding 69 patients who had not been available for follow-up until 1 year after surgery or died. The patients were divided into suture fixation and wiring fixation groups. Relationships of operation time, estimated blood loss, tip-to-stem distance, union rate, and physical performance in the groups of suture fixation and wiring were analyzed respectively.ResultsChanges in the tip-to-stem distance between the initial assessment at 1 year after surgery were statistically significantly different between the suture fixation group and wiring group (p < 0.001). There was no significant difference in change of the Koval score between the suture fixation and wiring groups (p = 0.362). The operation time and estimated intraoperative blood loss were statistically significantly lower in the suture group than in the wiring group (p < 0.001). There was no significant difference in the union rate between the groups (p = 0.470).ConclusionsCompared to tension-band wiring, the suture fixation technique demonstrated an effective fixing force. In addition to the clinical results, it had an advantage of preventing complications due to shortening of the operation time and estimated intraoperative blood loss. Suture fixation of the greater trochanter is recommended for elderly patients with unstable intertrochanteric fractures.     

双极人工股骨头与PFNA在不稳定型股骨粗隆间骨折的疗效评析

目的评价双极人工股骨头置换与股骨近端防旋髓内针（PFNA）内固定治疗高龄骨质疏松性股骨粗隆间骨折的临床疗效,探讨其合理的治疗方法。方法回顾性分析2009年1月~2013年9月期间,在农垦三亚医院采用双极人工股骨头置换（32例）与PFNA内固定治疗（43例）共75例70岁以上的股骨粗隆间骨折患者。骨折根据AO/OTA系统分型：转子间二部分骨折分为A1型（稳定骨折）,多部分骨折为A2型（不稳定骨折）,反斜形转子间骨折为A3型（不稳定骨折）。比较2组在手术时间、出血量、术后卧床时间、并发症发生率及术后1年病死率、Harris功能评分、人工关节松动率、住院时间等方面的指标。结果 75例均获得16~24个月随访,43例PFNA组骨折均顺利愈合;32例半髋关节置换假体无脱位、假体柄无明显下沉。两组术后髋关节功能优良率、内置物并发症差异不明显（P〉0.05）,但半髋关节置换组内科并发症更少（P〈0.05）、切口长度较大（P〈0.05）、手术时间较长（P〈0.05）、术中出血量较多（P〈0.05）、术后卧床时间及下地时间较短（P〈0.05）。结论双极人工股骨头置换术和PFNA内固定术均是治疗高龄患者粗隆间不稳定骨折的有效方法。双极人工股骨头治疗高龄伴严重骨质疏松的不稳定型股骨粗隆间骨折,下床活动早、早期并发症发生率低、功能恢复满意,可明显提高患者的生活质量。
