AbstractA retrospective review was performed of 46 consecutive ambulatory children with cerebral palsy and tibial torsion who underwent 72 distal tibial derotational osteotomies without concomitant fibular osteotomy. The average amount of derotation measured at surgery was 21 +/- 5 degrees. The average change in thigh-foot angle at follow-up was 21 +/- 9 degrees. There were eight perioperative complications (11%): three delayed unions, three superficial wound dehiscences, one case of osteomyelitis, and one superficial pin tract infection. There were no incidences of malunion or nonunion. Preoperative and postoperative three-dimensional gait analysis data were used to determine the effect of distal tibial osteotomy on foot progression angle in seven subjects (11 limbs). Foot progression improved significantly. This study shows that distal tibial osteotomy alone (without concomitant fibular osteotomy) is an effective and safe procedure for correcting and maintaining correction of tibial torsion in patients with cerebral palsy.
