We placed four pins using an alignment jig, performed a percutaneous osteotomy, and applied an external fixator after derotation. Postoperative radiographs showed accurate tibial derotation and pin placement in all patients. Nine patients developed superficial pin-tract infections that resolved with antibiotic treatment. Two developed fractures after removal of the external fixator, which healed in a plaster cast. Operative treatment of these cases with an external fixator is safe, effective, and well tolerated.
