Subluxation and dislocation of the hip: a complication following hip pinning.

In 11 subluxations and four dislocations of the hip, following the internal fixation of intracapsular or intertrochanteric fractures, sepsis was proved in 12. Subluxations were diagnosed radiographically between 2 and 26 months following injury. Dislocations occurred following unstable intertrochanteric fractures, stabilized by valgus reduction, medial displacement, and osteotomy of the greater trochanter, and were diagnosed between 10 days and 9 weeks post-fracture. Treatment alternatives included implant removal, resection arthroplasty, and replacement arthroplasty in selected cases.
