Delayed Total Hip Arthroplasty for Failed Acetabular Fractures: The Influence of Initial Fracture Management on Outcome After Arthroplasty

Background

Total hip arthroplasty (THA) provides a successful salvage option for failed acetabular fractures. The complexity of arthroplasty for a failed acetabular fracture will depend on the fracture pattern and the initial management of the fracture. Our objective was to compare the midterm outcome of THA between patients who presented with failed acetabular fractures following initial surgical or nonsurgical treatment.

End-stage posttraumatic osteoarthritis treated with THA in osteogenesis imperfecta

Osteogenesis imperfecta is an incurable genetic disorder manifested with altered bone quality that predisposes patients to a multitude of fractures throughout their lives, including acetabular fractures. The management of acetabular fractures in patients with osteogenesis imperfecta remains a challenging clinical problem, with a paucity of literature supporting treatments and their outcomes. Limited reports in the literature validate the use of total hip arthroplasty (THA) in patients with osteogenesis imperfecta, and they describe the adult population only.This article describes a case of delayed diagnosis of a transverse acetabular fracture and femoral head impaction fracture that led to posttraumatic end-stage hip osteoarthritis in a 16-year-old boy with osteogenesis imperfecta (Sillence Type I) that was sustained after minimal trauma. Clinical examination 3 months postinjury revealed a significant pelvic obliquity, severe pain with hip range of motion, and limited hip range of motion. Imaging studies revealed a complete loss of articular cartilage and significant joint effusion.The patient underwent THA. No postoperative complications occurred. Two-year follow-up showed an excellent clinical result. The patient's hip was pain free, and he was able to walk with no limp.The authors are unaware of any reported cases of children with osteogenesis imperfecta undergoing THA. Based on the reported literature and the authors' experience, THA can be a reliable surgical option for patients with osteogenesis imperfecta.     

Acute Total Hip Arthroplasty in Acetabular Fractures in the Elderly Using the Octopus System : Mid Term to Long Term Follow-Up

Patients older than 55 years presenting with acetabular fractures fulfilling the criteria for acute total hip arthroplasty (THA) were included. Cementless THA was done using the Octopus System and autologous bone grafting. 15 patients were available for latest follow up. The average follow-up was 81.5 months (62–122 months). Mean Harris Hip Score was 91.1. 10 patients were walking without any support while 5 were using a cane. There were no cases of acetabular or femoral component loosening. This method of treatment is promising in the older population as there is deficiency of bone stock which may lead to fixation failures. It is, therefore, worthwhile to recommend primary THA using the Octopus system in the successful management of selected types of acetabular fractures in the elderly.     

Cementless total hip arthroplasty in the treatment after acetabular fractures

Introduction

The outcomes of total hip arthroplasty (THA) for the treatment of posttraumatic arthritis after acetabular fractures were inferior to those after primary non-traumatic THA.

Methods

This study was performed in academic level I trauma center. From January 2011 to December 2014, a consecutive series of 21 patients (9 females), with average age of 56.7 years (range 29–75 years) who had posttraumatic hip joint arthritis after acetabular fractures, were included in our study. All patients underwent cementless THA. The average duration of follow-up was 26 months (range 24–36 months).

Results

At the latest follow-up, all patients could walk independently, thirteen (62%) patients had excellent Harris hip score, five (24%) had good HHS, and 3 (14%) had fair score. WOMAC scale decreased from 63 (range 42–92) to 4 (range 0–19). Two patients (9.5%) had heterotopic bone formation which did not affect the activity of the patients. There were no signs of loosening of the acetabular cups or around the femoral stem.

Conclusion

Cementless THA is an ideal treatment for posttraumatic hip arthritis with anatomic restoration of the hip center to improve the functional results and decrease the incidence of complications and revision rate.

     

Anterior Hip Dislocation: Characterization of a Rare Injury and Predictors of Functional Outcome

BackgroundAnterior native hip dislocation remains poorly studied due to the rarity of the injury. The aim of this study was to describe injury characteristics of anterior hip dislocation, detail its initial treatment, and determine the intermediate term outcomes including the rate of conversion to total hip arthroplasty (THA).MethodsA cross-sectional study was performed at a single urban academic Level 1 trauma center for patients who sustained traumatic anterior hip dislocations from 2010-2017. Baseline demographic, injury, and treatment data were recorded. Patients were contacted to inquire about subsequent surgery and complete functional outcome questionnaires. Available post-operative radiographs were also reviewed.ResultsThirty-two anterior hip dislocations met inclusion criteria and were included in the study. 69% of dislocations were obturator dislocations and 31% iliac dislocations. Only 22% were simple dislocations with the remainder having an associated femoral head fracture and/or acetabular fracture. Iliac dislocations were more likely to be associated with acetabular fractures and require surgical treatment while obturator dislocations were more likely to be simple dislocations or have femoral head fractures. Excluding two patients treated with acute THA at the time of injury, follow-up information was available for 16 patients at a minimum of eighteen months from the time of injury. Only one required subsequent conversion to THA. For the remaining fifteen patients, modified Harris hip scores (mHHS) averaged 82.6, PROMIS global physical health averaged 51.9, and PROMIS global mental health averaged 48.3 with mean follow-up of 4.2 years. mHHS was significantly higher for obturator dislocations and a negative association was seen with age.ConclusionsObturator dislocations occurred twice as frequently as iliac dislocations. Associated acetabular or femoral head fractures are common. Conversion to THA was low, occurring in only 1 of 16 patients not treated with acute arthroplasty. Obturator dislocations and age less than 45 years old at the time of injury were associated with better functional outcome at intermediate term follow-up.     

Total hip arthroplasty,combined with a reinforcement ring and posterior column plating for acetabular fractures in elderly patients: good outcome in 34 patients

Background and purpose — Low-energy acetabulum fractures are uncommon, and mostly occur in elderly patients. Determining the optimal operative treatment for such fractures is challenging. Here we investigated whether acutely performed total hip arthroplasty plus posterior column plating (THA) reduced complications and reoperations compared with open reduction and internal fixation (ORIF) in elderly patients with acetabular fractures.

Patients and methods — We retrospectively reviewed the records of 59 patients, > 55 years of age, with complex acetabular fractures, caused by low-energy trauma, treated between January 2008 and September 2017. Of these patients, 34 underwent acute THA, and 25 ORIF alone. Patient and implant survival were compared between groups using Kaplan–Meier survival analysis and Cox multiple regression. Functional outcomes assessed by Oxford Hip Score (OHS) were compared between the THA patients and those 9 ORIF patients who underwent secondary THA due to posttraumatic hip osteoarthritis (OA) during follow-up.

Results — Overall patient survival was 90% (95% CI 82–98) at 12 months, and 64% (CI 47–81) at 5 years. Of 25 ORIF patients, 9 required secondary THA due to posttraumatic OA. Large fragments on the weight-bearing acetabular dome upon imaging predicted ORIF failure and secondary THA. The acute THA group and secondary THA group had similar 12-month OHS.

Interpretation — Acute THA including a reinforcement ring resulted in fewer reoperations than ORIF alone in elderly patients with acetabular fractures. These findings support acute THA as first-line treatment for complex acetabular fractures in elderly patients.

Cementless Total Hip Arthroplasty for Adult Patients With Sequelae From Childhood Hip Infection: A Medium-Term Follow-Up Study

BackgroundThe aim of this study is to evaluate midterm clinical and radiographic results of total hip arthroplasties (THAs) with cementless implants for adult patients with sequelae from childhood hip infection.MethodsBetween 2002 and 2016, 165 patients (165 hips) who had a hip infection during childhood were treated with THAs with cementless implants. The average duration of follow-up was 93.5 months (range 26-206). Clinical results were evaluated via the Harris Hip Score and radiographic results were analyzed with postoperative serial X-rays.ResultsThe average Harris Hip Score increased from 27 (range 8-53) before surgery to 91 (range 45-100) at the latest follow-up examination (P < .001). At the latest follow-up evaluation, 9 cementless acetabular components demonstrated partial, nonprogressive radiolucencies. No subsidence of more than 2 mm or evidence of a radiolucent line was observed around the femoral components. Intraoperative periprosthetic fractures occurred in 11 hips, including 3 acetabular fractures, 2 fractures of greater trochanter, 1 femoral shaft fracture, and 5 fractures of femoral calcar. Postoperative complications included 3 cases of periprosthetic infection, 1 episode of dislocation, 1 case of a femoral periprosthetic fracture, 5 cases of sciatic nerve injury, 1 case of femoral nerve injury, and 1 case of squeaking from a ceramic bearing surface.ConclusionCementless THA for adult patients with sequelae from childhood hip infection presents significant technical challenges and a relatively high complication rate. With meticulous surgical planning and anticipation for the key technical challenges frequently encountered, the medium-term clinical and radiographic results of THA in this setting were good with high implant survivorship and patient satisfaction.     

颗粒松质骨压紧植骨全髋关节置换术治疗创伤性髋关节炎的疗效

目的探讨颗粒松质骨压紧植骨全髋关节置换术(THA)治疗髋臼骨折继发创伤性髋关节炎的疗效。方法1998年12月-2005年5月,对15例髋臼骨折继发创伤性髋关节炎患者行颗粒松质骨压紧植骨THA,所有患者髋臼假体均采用骨水泥固定,颗粒骨均取自体骨,术后24h后开始被动活动,3个月后开始全负重锻炼。临床随访采用Harris髋关节评分(HSS)系统评分,对任何原因引起髋臼假体翻修均视为临床失败。根据Conn等影像学评价法观察颗粒骨长人情况,根据DeLee的三区法测量臼杯、骨水泥与移植骨间的界面宽度,臼杯的移位程度则依据其相对于泪点间线的距离而定。结果14例患者获得平均4．3年(1．0-7．5年)随访,HHS评分由术前平均42分(10-62分)提高到随访结束时平均84分(58-98分)。1例髋部有轻度疼痛,无患者行翻修手术。大部分髋部恢复了其正常的旋转中心,仅有2例高出对侧0．8 mm。大多数患者影像学表现稳定,2例在Ⅰ区和Ⅲ区出现进行性增宽的透亮带,1例在Ⅲ区出现非进行性增宽的透亮带。1例臼杯假体在术后7年出现明显移位(6 mm),但并没有行翻修手术。结论颗粒骨压紧植骨技术作为一种生物学髋臼重建方法,其联合THA治疗髋臼骨折后继发创伤性关节炎伴髋臼缺损的疗效令人满意,能够恢复髋关节的正常解剖和功能活动。

Total Hip Arthroplasty After Prior Acetabular Fracture: Infection Is a Real Concern

BackgroundAcetabular fractures often require surgical intervention for fracture fixation and can result in premature osteoarthritis of the hip joint. This study hypothesized that total hip arthroplasty (THA) in patients with a prior acetabular fracture who had undergone open reduction and internal fixation (ORIF) is associated with a higher rate of subsequent periprosthetic joint infection (PJI).MethodsAbout 72 patients with a history of acetabular fracture that required ORIF, undergoing conversion THA between 2000 and 2017 at our institution, were matched based on age, gender, body mass index, Charlson comorbidity index, and date of surgery in a 1:3 ratio with 215 patients receiving primary THA. The mean follow-up for the conversion THA cohort was 2.9 years (range, 1-12.15) and 3.06 years (range, 1-12.96) for the primary THA.ResultsPatients with a previous acetabular fracture, compared with the primary THA patients, had longer operative times, greater operative blood loss, and an increased need for allogeneic blood transfusion (26.4% vs 4.7%). Most notably, PJI rate was significantly higher in acetabular fracture group at 6.9% compared with 0.5% in the control group. Complications, such as aseptic revision, venous thromboembolism, and mortality, were similar between both groups.ConclusionThe present study demonstrates that conversion THA in patients with prior ORIF of acetabular fractures is associated with higher complication rate, in particular PJI, and less optimal outcome compared with patients undergoing primary THA. The latter findings compel us to seek and implement specific strategies that aim to reduce the risk of subsequent PJI in these patients.     

全髋关节置换术治疗髋臼骨折后创伤性关节炎的疗效观察

目的探讨人工全髋关节置换术治疗髋臼骨折后髋关节创伤性骨关节炎的疗效。方法本组共随访髋臼骨折后髋关节创伤性骨关节炎患者32例32髋,男20例,女12例,平均年龄45.3岁。本组患者全部行人工全髋关节置换术治疗。所有假体均采用生物型假体。采用Harris、UCLA评分对患者术前术后的髋关节功能进行评分,拍摄标准双髋正位片对假体状态进行影像学评估。结果本组患者平均随访26个月,Harris评分由术前42.5分增加到术后93.6分,UCLA评分由术前3.2分增加到术后8.1分,改变有统计学差异。影像学评估显示假体位置良好,无假体松动、关节脱位、感染及明显假体周围骨溶解等并发症。结论全髋关节置换是治疗髋臼骨折后创伤性关节炎的有效治疗手段,术中尽量采用生物型假体,近期随访结果令人满意。     

The Harris-Galante cementless THA: a 19- to 25-year follow-up study

The goal of this study was to evaluate the long-term survivorship of primary cementless total hip arthroplasty (THA) using Harris-Galante porous I acetabular and Harris-Galante porous femoral components. From July 1985 to December 1991, we performed primary cementless THA on 76 hips (70 patients). Twenty-nine patients (31 hips) died due to causes unrelated to the THA, and 6 patients (7 hips) were lost to follow-up. Of 76 hips (70 patients) studied, 38 hips (35 patients) were available for follow-up at a mean 22.5 years (range, 19-25 years) postoperatively. Mean patient age at index procedure was 51.2 years (range, 42-65 years). Average Harris Hip Score was 40.5 points preoperatively and 85.8 points at final follow-up. No patient had an early or late postoperative deep infection. Radiographically, the acetabular component fixation was stable in all 38 hips. The femoral component was bone-ingrown in 26 hips, stable-fibrous in 10, and unstable in 2. One unstable hip required revision of the femoral component. Dissociation of the polyethylene liner occurred in 3 hips without fractures of the metal locking tines and required revision of the polyethylene liner and the articular head. A total of 4 hips had documented revision, and 1 femoral component failed radiographically. The survival rate with the endpoint defined as revision surgery and radiographic loosening was 86.8% at 22.5 years of follow-up. Mean polyethylene wear was 0.085 mm/year (range, 0.031-0.15 mm). This study found that the Harris-Galante porous I acetabular and Harris-Galante porous femoral components produce excellent long-term results.     

Efficacy of cementless total hip arthroplasty in patients on long-term hemodialysis

We retrospectively reviewed 11 hip arthroplasties in 7 patients receiving long-term (15 years) hemodialysis for chronic renal failure. Osteonecrosis of the femoral head, osteoarthritis, and amyloid arthropathies were treated by total hip arthroplasty (THA) or bipolar hemiarthroplasty (BHA) using cementless anatomic medullary locking stem. The average follow-up period was 8 years and 3 months (range, 3-13 years). The D'Aubigne and Postel hip score was restored to 14.5 postoperatively from 7.7 preoperatively. All femoral cementless components achieved bone-ingrown fixation. Although 1 BHA resulted in central migration, there was no loosening of the cementless acetabular component. We are encouraged by the predictable long-term stability of the bone-implant interface achieved by cementless fixation with an extensively coated implant. Cementless THA remains a useful treatment option for patients on long-term hemodialysis.     

Total hip arthroplasty for posttraumatic arthritis after acetabular fracture

Total hip arthroplasty (THA) outcomes for posttraumatic arthritis after acetabular fracture have yielded inferior results compared to primary nontraumatic THA. Recently, improved results have been demonstrated using cementless acetabular reconstruction. Thirty-two patients underwent THA for posttraumatic arthritis after acetabular fracture; 24 were treated with open reduction internal fixation, and 8 were managed conservatively. Time from fracture to THA was 36 months (6-227 months). Average follow-up was 4.7 years (2.0-9.7 years). Harris Hip score increased from 28 (0-56) to 82 points (20-100). Six patients required revision. Five-year survival with revision, loosening, dislocation, or infection as an end point was 79%. Survival for aseptic acetabular loosening was 97%. Revision surgery correlated with nonanatomic restoration of the hip center and a history of infection (P < .05). Despite obvious challenges, advances in fracture management and cementless acetabular fixation in THA demonstrate improved results for posttraumatic arthritis following acetabular fracture.     

Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis

ObjectiveMultiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients.MethodsMeta-analysis of 21 studies of 430 acetabular fractures with mean follow-up of 44 months (range, 17−97 months). Two independent researchers searched and evaluated the databases of Ovid, Embase, and United States National Library of Medicine using a Boolean search string up to December 2019. Population demographics and complications, including presence of heterotopic ossification (HO), dislocation, infection, revision rate, neurological deficits, and venous thromboembolic event (VTE), were recorded and analyzed.ResultsWeighted mean Harris Hip Score was 83.3 points, and 20% of the patients had reported complications. The most common complication was HO, with a rate of 19.5%. Brooker grade III and IV HO rates were lower at 6.8%. Hip dislocation occurred at a rate of 6.1%, 4.1% of patients developed VTE, deep infection occurred in 3.8%, and neurological complications occurred in 1.9%. Although the revision rate was described in most studies, we were unable to perform a survival analysis because the time to each revision was described in only a few studies. The revision rate was 4.3%.ConclusionsAcute THA is a viable option for treatment of acetabular fracture and can result in acceptable clinical outcomes and survivorship rates in older patients but with an associated complication rate of approximately 20%. Considering the limited treatment options, THA might be a viable alternative for appropriately selected patients.

Jumbo cups for revision of acetabular defects after total hip arthroplasty: a retrospective review of a case series

The treatment of acetabular bone defects presents a great challenge in revision total hip arthroplasty (THA). The purpose of this study was to evaluate the clinical and radiological outcome of revision THA using jumbo cups for acetabular reconstruction after applying the bone-grafting technique. We studied 17 patients with acetabular defects ranging from Type 2A to Type 3A according to Paprosky`s classification. According to the AAOS-score twelve patients were classified as Type II and five patients as Type III. Uncemented press-fit cups with an outer diameter larger than 64 mm were used in all cases. Fifteen patients received morselized bone allografts. In eight patients an additional screw fixation was necessary. The mean follow-up period was 82 months (range 33–149). The mean Harris Hip Score was preoperatively 62 and at the time of the last follow-up examination 83 points (p = 0.007). Two acetabular components failed, one due to aseptic loosening and another one due to septic loosening. There was a trend of displacement of the femoral head centre towards the infero-lateral position after using jumbo cups that approached statistical significance (p = 0.065). Closure of acetabular defects of Types 2A to 3A according to Paprosky’s classification and type II to III according to the AAOS-score respectively can be satisfactorily accomplished using jumbo cups after applying the bone-grafting technique.
