髋关节置换

Objective To analyse the failed total hip arthroplasty and to improve its long-term results.

目的对人工髋关节置换术后失败的病例进行分析，总结经验，提高人工髋关节置换术的长期疗效。

BACKGROUND: Prosthesis selection for total hip replacement is determined by geometrical matching with femoral medullary cavity of patients and the optimal biodynamics. It is of great significance for elevating outcomes of total hip replacement.

背景：人工髋关节置换术前选择假体时，不仅要考虑在几何学上达到与患者股骨髓腔的匹配，而且还要在生物力学性能上达到最优，这对提高全髋关节置换术后疗效，具有较现实的意义。

OBJECTIVE To evaluate the clinical effect of total hip joint replacement and hemiarthroplasty in treatment of fracture of femoral neck in old patients.

目的 比较全髋关节置换术与半髋关节置换术治疗高龄股骨颈骨折的疗效和手术方式的选择。

Elderly patients with conservative treatment of femoral neck fracture in the bone unhealing rate, avascular necrosis rate and bed incidence of complications are very high, often need surgical treatment, Currently Artificial arthroplasty better able to load the early running, and significantly improved the quality of life. Orthopedist has been universally acknowledged, which was also hemiarthroplasty for and hip arthroplasty mainly, But these indications of operation and the pros and cons of surviving in numerous disputes, By comparing our double-action Hemiarthroplasty with total hip arthroplasty for femoral neck fracture in the elderly average operative time, The average blood transfusion, the average length of stay, average hospital charges, early complications, Harris score, Oxford hip score standards evaluation discussion bipola Femeral Head placement with total hip arthroplasty in the treatment of femoral neck fracture in the elderly: the advantages and disadvantages.

老年患者股骨颈骨折保守治疗的骨不愈合率、股骨头缺血坏死率及卧床并发症发生率很高，常需要行手术治疗，目前应用人工关节置换疗效较好，能早期负重行走，生活质量明显提高，已得到骨科医师的普遍认同，其中又以人工股骨头置换术和人工髋关节置换术为主，但这些术式的适应证及利弊尚存在诸多争议，我们通过比较双动人工股骨头置换与全髋关节置换治疗老年人股骨颈骨折的平均手术时间、平均输血量、平均住院时间、平均住院费用、早期并发症、Harris评分、牛津髋关节评分标准评价来探讨双动人工股骨头置换与全髋关节置换在老年人股骨颈骨折治疗中的优势与劣势。

Objective: To explore the value of different surgicalmethods in the treatment of the displaced femoral neck fracture of the elderly.analyse joint function, complications, reversion factors Methods: An follow up study was done on 71 cases older than 60years who were treated with internal fixation, femoral head arthrop lasty and total hip joint replacement between 2000 and 2005 to compare the difference upon operation time, blood loss, duration of hospi-talization , joint function evaluation one and two years after operation , complications and reversionrate.

目的：探讨加压空心螺钉内固定术、人工股骨头置换术和人工全髋关节置换术在治疗老年人移位性股骨颈骨折中的临床价值。分析术后髋关节功能、并发症、二次手术或翻修率等相关因素。方法：对2000—2005年于长春中医药大学第一附属医院骨科收治的71例60岁以上移位性股骨颈骨折患者进行了随访研究，比较AO加压空心螺钉内固定术、人工股骨头置换术和人工全髋关节置换术在手术时间、出血量、住院时间、术后下地时间、术后12个月和24个月的髋关节功能评价、并发症以及二次手术率方面的差异。

Or else, posterior approach is a better choice. As regard to patients who had both ankylosed hips and only one hip can be undergone total hip replacement, after the operation, the function of this hip is good, but the patient can't walk because of the influnce of the other hip, so that the Harris hip score is very low, often less than 70 points. But this didn't indicate that the function of the hip is poor. Due to that, we recommend that the Charnley hip score should be adopted under this condition.

对双侧强直患者，行单侧置换后，该髋关节良好，但受对侧或其他关节的影响，患者仍不能行走，Harris评分仍很低，在70分以下，但这并不能说明术侧髋关节功能不好，因此，对经济状况不良或身体状况差者，不能同时行双侧手术，单侧髋关节置换后功能评分将受影响，双侧髋关节强直的患者只行单侧手术后的评分不适合用Harris评分，而用Charnley评分较为合适。

Material and Methods:unipolar hip replacement in 2 patients,bipolar hip replacement in 10 patients,total hip replacement in 6 patients,mean years of follow-up is 2years and 4months,applying with Harris score system to examine patients,while photoing hip X-ray on anteroposterior and lateral sites,.

材料与方法：对18例髋关节置换术后患者进行随访，其中髋关节置换单极2例，双极10例，全髋6例，其平均随访时间为2年4个月，应用公认的Harris髋部评分系统，在疼痛、功能、活动范围和畸形四个方面进行临床检查，同时行髋部正侧位拍片检查。

In addition, some patients chose to have a traditional total hip arthroplasty instead of a resurfacing arthroplasty.

此外，也有些患者愿意进行传统的全髋关节置换，而不是髋关节表面置换。

In addition, some patients chose to hae a traditional total hip arthroplasty instead of a resurfacing arthroplasty.

此外，也有些患者愿意进行传统的全髋关节置换，而不是髋关节表面置换。

BACKGROUND: Common complication of traditional joint replacement is hip joint dislocation and large head joint implant can effectively solve this problem.

背景：传统髋关节置换最常见的并发症是置换后髋关节脱位，而大头关节能有效地解决这一问题。
