Septic arthritis of the hip in infancy: long-term follow-up.

At a mean 15-year follow-up, the authors evaluated five hips in five patients who had complete destruction of the femoral head and neck from septic arthritis when they were 3 months old. All patients were treated with a trochanteric arthroplasty in combination with a proximal femoral varus osteotomy at a mean age of 30 months in an attempt to salvage a femoral-pelvic articulation. Results suggest this treatment can provide a stable, painless, and functional hip, with an improved gait and less leg-length discrepancy than predicted if no reconstructive effort were attempted.
