The results of internal fixation of 55 subcapital fractures of the femoral neck with a one-hole plate dynamic hip screw are presented. Two fractures could not be satisfactorily fixed and the procedures were converted to hemi-arthroplasties, but the remainder united within 6 months. The rate of avascular necrosis after union was 3 per cent in undisplaced and 31 per cent in displaced fractures. This method of fixation appears to produce a lower non-union rate than multiple pins in suitable fractures without affecting the incidence of late avascular necrosis.
本文介绍了使用单孔钢板动力髋螺钉对55例股骨颈头下型骨折进行内固定的结果。有2例骨折未能得到满意固定，手术改为半髋关节置换术，但其余骨折在6个月内愈合。愈合后无血管性坏死率在无移位骨折中为3%，在移位骨折中为31%。这种固定方法在合适的骨折中似乎比多根钢针产生更低的不愈合率，且不影响晚期无血管性坏死的发生率。
