Pseudoarthrosis after Septic Arthritis of the Hip Resulting in Coxa Vara.

We treated a rare case of coxa vara with pseudoarthrosis of the femoral neck resulting from septic arthritis of the hip at birth. The patient had been treated at another medical center, and was referred to our hospital because pathological dislocation was suspected. We performed valgus femoral osteotomy when he was two years old. The hip remained stable and the development of the femoral head was good, but coxa vara and leg length discrepancy progressed.
