Pipkin Type-II fractures of the femoral head.

Ten patients with a Pipkin Type-II fracture of the femoral head associated with dislocation of the same hip were treated and followed for two to five years. Five of these ten fractures, which were reduced anatomically after closed reduction of the dislocation, were treated by traction. All five healed and no evidence of avascular necrosis was identified radiographically or clinically at follow-up. Of the remaining five patients who had an unsatisfactory closed reduction, four were treated by open reduction and internal fixation with two screws and one, by excision of the comminuted fragment. Four of these five patients had no complications and one had avascular necrosis requiring total hip replacement after one year.
