Patients with cerebral palsy often develop rotational deformities of the lower extremities. These deformities may be caused by abnormal muscle tone, soft-tissue contractures, or bony malalignment. When rotational deformity persists after correction of the soft-tissue components, bony-realignment procedures are warranted to improve gait in ambulatory patients. ⋯ Gait velocity improved but not significantly. Moment data demonstrated a trend toward normal. This study demonstrates that the derotational distal tibial and fibular osteotomy stabilized with percutaneous crossed Kirschner wires is a safe, reliable, and effective procedure for correcting rotational deformities of the leg in patients with cerebral palsy.

Despite a tendency for rotational abnormalities of the lower leg in children to improve spontaneously over time, some fail to correct and require corrective derotation osteotomy. In this retrospective study, we report the technique and results of the distal transverse tibial and fibular derotation osteotomy with Kirschner-wire fixation performed in 63 limbs of children with cerebral palsy, clubfoot, idiopathic tibial torsion, and myelomeningocele, as well as other less common conditions. ⋯ There were three (4.8%) complications, including late fracture (one), cross-union (one), and distal physeal closure (one). We conclude that transverse, same-level, distal tibial and fibular osteotomy fixated with crossed Kirschner wires is a safe, efficient, and effective surgical approach to the treatment of children with tibial torsion in a variety of clinical conditions.
