The Method and Evaluation of Measurement of Hip Joint in the Gluteal Muscle Contracture in Children / 实用放射学杂志

ABSTRACT

Objective To evaluate the effect on the development of hip joint by gluteal muscle contracture and to study the significance of early surgical treatment for this disease.Methods X-ray films of pelvis in 102 cases with gluteal muscle contracture were taken before surgical treatment.The acetabular index,the neck-shaft angle and the acetabular-head index(AHI) were measured.Results The neck shaft angle(x=149.64) and the CE angle(x=34.12) were increased,the acetabular-head index(x=72.3%) was decreased,and the acetabulainr index(x=13.6) was normal.Conclusion The gluteal muscle contracture can causes coxa valga and subluxation of the hip joint,early surgical treatment is needed.
