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.
