碳-钛组合式人工股骨头临床应用远期随访结果

Long-term results of hemi-arthropl asty with Carbon-Titanium combined femoral head

目的为了进一步了解碳-钛组合式人工股骨头长期临床应用的效果。方法自1980年4月～2000年4月,本地区应用5年以上的病例共72例,仅就健在的58例进行随访,57例进行了X线检查。结果随访时间最短5年,最长18年7个月,平均10年8个月。X线检查57例中髋臼完好50例,完好率为87.7%。不同程度的髋臼磨损7例,占12.3%。髋关节周围异位骨化2例均在BrookerⅡ级以下,不影响髋关节功能。柄下沉3例,占5.3%。无一例出现感染及中心性脱位。采用Harris髋关节评分标准进行评分,平均为96分。治疗满意率达96%。结论对股骨颈骨折患者如需行人工股骨头置换,以选择碳-钛组合式人工股骨头为宜。

Objective To study the long-term results of Carbon -Titanium combined femoral head.Methods From April,1980to April,2000,72patients undergone hemi-arthroplasty of hip joint with more than five years followed up were reviewed.Among them,58cases were still alive,and 57of them were ex-amined with X-ray films.Results The follow-up was between 5years and18.7years,with an average of 10years and 8months.X-ray films of 50p atients showed that the acetabular c onfiguration was normal,with the ratio of 87.7%(50/57).In 7cases,the X-ray films demonstr ated different wear in the acetabula r profile,with the ratio of 12.3%.Two patients suffered from acetabular ossification,both of them were classified as less than Brooker II degree,and had a satisfactory function of the hip.The prosthetic stem sinkage happened in 2cases(5.3%).There was no complication of infection and hip central dislocation.Evaluation by Harris method,the average scores was 96,th e satisfactory rate of the clinical r esults was 96%.Conclusion Carbon -Titanium combined femoral head replacement is an alternative fo r patients with femoral neck fractur e in need of arthorplasty.
