Correction of Ankle and Hindfoot Deformities by Supramalleolar Osteotomy

Ankle and hindfoot deformities in 11 patients with a mean age of 15 (range, four to 35) have been gradually corrected by an Ilizarov external fixator. In all patients, supramalleolar osteotomy was utilized by percutaneous drilling and osteotomy technique. The patients were evaluated clinically by th...

Description
Summary:Ankle and hindfoot deformities in 11 patients with a mean age of 15 (range, four to 35) have been gradually corrected by an Ilizarov external fixator. In all patients, supramalleolar osteotomy was utilized by percutaneous drilling and osteotomy technique. The patients were evaluated clinically by the AOFAS scoring system and radiologically by malorientation and malalignment tests described by Paley. The purpose of the current study is to evaluate the efficacy of supramalleolar osteotomy and correction by an Ilizarov device in treating hindfoot and ankle deformities. The mean external fixation period was five (2.5 to eight) months. The mean interval between the operation and last follow-up examination was 19 (13 to 26) months. The patients improved an average of 30 points after the operation regarding to AOFAS score. A plantigrade foot was achieved in the whole group. Radiologically, no malalignment or malorientation was measured. Equal leg lengths were achieved in all nine patients with one exception. Complications were graded after Paley as minor problems in 11 patients and as obstacles requiring surgical interventions in four patients. Sequelae remained in only one patient. Ankle and hindfoot deformities caused by various etiologies are complicated by poor soft tissue condition and a short foot. A supramalleolar osteotomy and Ilizarov external fixator can safely and effectively correct these deformities.
