Classification and surgical management of the severe sequelae of septic hips in children.

The treatment of the acute state of septic arthritis of the hip in children has been clearly outlined in the current literature. The treatment of residual anatomic deformity is less well understood; no classification or comprehensive treatment program has been documented. The following classification of the sequelae of septic hips in children is based on the presence or absence of a capital femoral epiphysis and hip stability. This classification defines the case material and outlines the anatomic problem requiring solution. Of ten patients with severe destruction of the femoral head followed for an average period of 11.2 years, there were eight satisfactory and two unsatisfactory results. Both unsatisfactory results were Type III hips with pseudarthrosis of the neck. Both had an average of five surgical procedures, compared with 2.2 procedures for patients with satisfactory results. The complications were leg-length discrepancy, hip instability, and scoliosis.
