Midterm results of "thrust plate" prosthesis

The aim of this investigation was to analyze the midterm results obtained with the metaphyseal fixation principle of the thrust plate prosthesis (TPP). Survival of 214 implants in 204 patients was analyzed. Clinical (Harris hip score) and radiologic examinations were carried out on 157 of 190 TPP with a postimplantation follow-up period of at least 5 years. Failure rate was 7.0% (9 aseptic and 6 septic loosening). Harris hip score increased from 36.9 +/- 13.5 points preoperatively to 91.2 +/- 13.1 points at follow-up. Eleven TPPs showed radiolucent lines not indicating prosthetic loosening. Thrust plate prosthesis is not an alternative to stemmed endoprostheses. It may be rarely indicated in very young patients where, because of their age, several revision operations can be expected.

定制型人工髋关节置换治疗股骨近端瘤性病变

目的探讨定制型人工髋关节置换治疗股骨近端瘤性病变的经验及临床效果。方法1994年2月~2002年11月,对11例股骨近端瘤性病变行股骨近端切除、带部分股骨假体的人工髋关节置换术。男7例,女4例。年龄40~69岁。左侧9例,右侧2例。其中股骨近端骨巨细胞瘤7例,软骨母细胞瘤2例,畸形性骨炎1例,骨纤维异常增殖症1例。行人工全髋关节置换6例,双极杯人工股骨头置换5例。结果术后9例获随访1~5年,2例失访。1例术后创面渗血、股部近端连续加压包扎5d后股四头肌功能丧失,股前部感觉消失;术后5年随访股四头肌肌力0级,股前部感觉减退,绳肌及小腿伸屈肌群肌力3级,跛行,需扶拐行走。5例股四头肌肌力3级,其中2例感觉股部近端阵发性疼痛,尤以久站及行走后疼痛明显,均为双极杯股骨头假体置换者;3例股四头肌力4级。8例髋关节外展10~27°,髋关节屈曲,平均74°。采用Harris标准评定,良(80~89分)3例,中(70~79分)5例,差(70分以下)1例。术后无感染,随访期间无肿瘤复发及假体松动。结论定制型人工髋关节置换治疗股骨近端瘤性病变是一种有效方法,但术后股四头肌无力发生率较高,与股四头肌上部附着处丢失有关。术中将股四头肌,特别是其附着的内、外、后肌间隔贯穿固定于假体体部,可望有效改善股四头肌肌力。     

Bone-preserving prosthesis with a single axis for treating osteonecrosis of the femoral head: midterm results for the thrust plate hip prosthesis

We studied 27 patients (31 joints) who underwent total hip arthroplasty (THA) using the thrust plate hip prosthesis (TPP) for osteonecrosis of the femoral head. The mean follow-up period was 56 months (range 38–72 months). Clinical evaluation by the Merle dAubigne and Postel system showed a significant improvement from a preoperative mean score of 8.1 to a final mean follow-up score of 16.6. Mechanical loosening developed about 1 year postoperatively in one joint with a bone defect. Grade 1 stress shielding was observed in four joints. Although indications for the TPP are restricted to certain cases, unlike the conventional intramedullary stem, much can be expected of TPP. It is an outstanding prosthesis for osteonecrosis of the femoral head of young patients in terms of bone preservation and physiological load transfer.

The cementless anatomic medullary locking femoral component: an independent clinical and radiographic assessment

Objective

To review the clinical performance of the anatomic medullary locking (AML) femoral stem in total hip arthroplasty.

Design

A clinical and radiographic review.

Setting

A tertiary lower limb joint replacement centre.

Patients

Two hundred and twenty-one patients with noninflammatory gonarthrosis.

Interventions

Two hundred and twenty-seven primary total hip arthroplasties with the noncemented AML component completed by two surgeons.

Main Outcome Measures

Independent review by two experienced reviewers of the postoperative Harris hip score, radiographs of component fixation, size and degree of diaphyseal fill.

Results

Harris hip score was 84 (range from 43 to 98); component fixation showed bone ingrowth in 41%, stable fixation with fibrous ingrowth in 56% and unstable fixation in 3%; severe thigh pain in 4% of cases correlated with unstable fixation, and there was mild thigh pain in 20% of cases.

Conclusion

The AML femoral stem performs well in replacement arthroplasty compared with other noncemented stems.     

Conversion of failed hemiarthroplasty to total hip arthroplasty: A short to mid-term follow-up study

Background:

The conversion of hemiarthroplasty (unipolar or bipolar) of the hip to total hip replacement has been reported to be associated with very high rates of intra- and postoperative complications. We present a prospective analysis of the outcome of conversion surgery in patients with failed hemiarthroplasty.

Materials and Methods:

Forty-four cases, 30 women and 14 men, average age 62 years (range 42-75 years) of failed hemiarthroplasty were converted to total hip replacement between January 1998 and December 2004. Groin pain was the main presenting complaint in the majority of the patients (24 out of 44). Six patients had infection and were operated with staged procedure. All acetabular and the majority (86.5%) of femoral components used in our series were uncemented.

Results:

After an average follow-up of 6.4 years (range, two to nine years) Harris hip scores improved from 38 (range 15-62) preoperatively to 86 (range 38 to 100) and 22 (50%) patients were community ambulators without support while 17 (38%) needed minimal support of cane. Fifteen out of 18 (83%) patients who had isolated groin pain preoperatively experienced no pain postoperatively while three patients (17%) reported only partial improvement. Intraoperative and postoperative complications included iatrogenic fracture of the femur in two, femoral perforation in two, partial trochanteric avulsion in two, fracture of the acetabular floor in three hips, and postoperative dislocation in one. None of these complications resulted in a poor long-term outcome. The rate of loosening in our series was 2.3% (one out of 44) after a mean follow-up of 6.4 years with a mean survival of 97.4% at 72 months.

Conclusion:

Conversion of symptomatic hemiarthroplasty to total hip arthroplasty is a safe option that gives good functional results, with marginally higher rates of intra-operative complications. The patients should be warned of the possibility of incomplete relief of groin pain postoperatively.     

人工髋关节置换术后5年内翻修的原因分析及处理方法

目的 探讨初次髋关节置换术后早期翻修的原因和防治方法.方法 回顾性分析2002年1月至2007年6月55例行人工髋关节翻修术患者的资料,其中术后5年内(含5年)翻修11例,翻修原因及翻修方式为:髋臼假体位置不良导致复发性脱位2例,手术调整髋臼假体位置;髋臼假体松动5例,翻修髋臼和(或)股骨假体;术后早期股骨假体周围骨折2例,行骨折复位固定;股骨头磨损髋臼1例,行全髋翻修;感染1例,行二期手术翻修.术前和术后随访采用Harris评分评估髋关节功能.术前Harris评分平均46分(28～62分).结果 本组随访时间16～76个月,平均36个月.术后Harris评分提高至平均86分(75～96分).术后出现并发症2例:1例术后局部血肿形成,4周后需再次手术清理血肿;1例术后关节不稳,经适当牵引制动后关节不稳定现象消失.无感染、深静脉血栓、主要血管和神经损伤等并发症发生.结论 初次髋关节置换早期翻修主要原因与髋臼假体处理、假体选择和安放技术不当有关,因此提高髋臼假体安放的手术技术有助于改善人工髋关节的疗效.     

股骨骨质疏松对骨水泥非骨水泥髋假体置换近期疗效之影响的临床对比研究

目的探讨股骨骨质疏松对骨水泥、非骨水泥髋假体置换近期疗效的影响,以期对其影响作出临床评价。方法对99例（99髋）术前有股骨干骺段骨密度测定值的人工髋关节置换患者进行了平均30个月的随访调查,回顾性分析骨水泥假体和非骨水泥假体在治疗正常骨密度患者和骨质疏松患者上的近期疗效的差别,采用Harris评分、大腿处疼痛、患者满意度三个方面进行比较。结果股骨骨质疏松患者,如选用非骨水泥假体置换,Harris评分及患者满意度均比骨水泥组低（P〈0．05）,而大腿处疼痛率却比骨水泥组高（P〈0．05）;与其在股骨正常骨密度患者上的治疗效果比较,Harris评分及患者满意度也较低（P〈0．05）,大腿处疼痛率较高（P〈0．05）。结论在治疗有股骨骨质疏松的患者时,采用非骨水泥假体置换的近期疗效降低,较骨水泥型假体置换组差,大腿处疼痛率也明显增高。所以,对骨质疏松的患者,以选用骨水泥假体为好。     

Primary cemented total hip arthroplasty: 10 years follow-up

Background:

Primary cemented total hip arthroplasty is a procedure for non-traumatic and traumatic affections of the hip. Long term follow-up is required to assess the longevity of the implant and establish the procedure. Indo-Asian literature on long term result of total hip arthroplasty is sparse. We present a 10-year follow-up of our patients of primary cemented total hip arthroplasty.

Materials and Methods:

We operated 31 hips in 30 patients with primary cemented total hip arthroplasty. We followed the cases for a minimum period of 10 years with a mean follow-up period of 12.7 years. The mean age of the patients was 60.7 years (range 37–82 yrs) male to female ratio was 2:1. The clinical diagnoses included - avascular necrosis of femoral head (n=15), sero positive rheumatoid arthritis (n=5), seronegative spondylo-arthropathy (n=4), neglected femoral neck fractures (n=3), healed tubercular arthritis (n=2) and post traumatic osteoarthritis of hip (n=2). The prostheses used were cemented Charnley’s total hip (n=12) and cemented modular prosthesis (n=19). The results were assessed according to Harris hip score and radiographs taken at yearly intervals.

Results:

The mean follow-up is 12.7 yrs (range 11-16 yrs) Results in all operated patients showed marked improvement in Harris hip score from preoperative mean 29.2 to 79.9 at 10 years or more followup. However, the non-inflammatory group showed more sustained long term improvement as compared to the inflammatory group, as revealed by the Harris hip score. Mean blood loss was 450ml (±3.7 ml), mean transfusion rate was 1.2 units (±.3). The complications were hypotension (n=7), shortening >1.5 cm (n=9), superficial infection (n=2) and malposition of prosthesis (n=1).

Conclusion:

The needs of Indian Asian patients, vary from what is discussed in literature. The pain tolerance is greater than western population and financial constraints are high. Thus revision surgery among Indian-Asian patients is less compared to western yard sticks.

Opioid use prior to total hip arthroplasty leads to worse clinical outcomes

Purpose

The purpose of this study was to compare the clinical outcomes of patients undergoing total hip arthroplasty (THA) who had been using narcotic medications prior to surgery to those who had not used them.

Methods

Fifty-four patients (62 hips) who had required opioid analgesia for hip pain in the three months prior to THA were compared to a matched group of opioid-naïve patients. Narcotic consumption was converted to a standardized morphine equivalent dose and compared between both groups of patients during their hospital stay, after six weeks, and at final follow-up. Other outcome measures included clinical outcome scores and the proportion of patients remaining on narcotic pain medication at final follow-up.

Results

The narcotic group required significantly higher total daily opioid doses as inpatients had a longer hospital stay and a higher proportion of patients who remained on opioids at six weeks and at final follow-up. Of the patients who were taking opioids pre-operatively, 81 % were able to wean off opioids at final follow-up. At a mean post-operative follow-up of 58 months (range, 24–258 months), Harris hip scores were lower in the narcotic group, with a mean of 84 compared to 91 points in the matching group. However, in both cohorts, there were significant improvements in Harris hip scores compared to pre-operative outcomes.

Conclusions

Patients who use narcotics prior to total hip arthroplasty may be more likely to suffer from opioid-induced hyperalgesia after surgery and have worse clinical outcomes. When possible, efforts should be made to use other modes of analgesia or wean patients from their use prior to total hip arthroplasty.     

成人DDH患者保髋手术失败后的THA疗效分析
