Abstract

Purpose: We evaluated the degree of femoral and tibial torsion in, and the efficacy of two operative procedures for, resistant idiopathic clubfoot with toe-in gait.
Materials and Methods: Thirty one feet in 23 patients (average age at the time of revision surgery 4.3 years) were studied. CT was used to determine femoral anteversion and tibial torsion. Two different operative procedures were applied, depending on the degree of toe-in gait: group 1 (10 feet whose toe-in gait was not severe) - soft tissue release, anterior tibial tendon transfer and mid-foot (cuboid closing and cuneiform opening) osteotomy; group 2 (21 feet which had relatively severe toe-in gait) - supramalleolar external rotation osteotomy of the distal tibia (SEROT), along with the same procedure as group 1. Mean follow-up period after revision surgery was 6.3 years. Results were assessed radiologically and clinically with the Dimeglio classification and Clubfoot Assessment Protocol.
Results: The mean femoral anteversion and external-tibial torsion of the affected side were increased. Twenty eight of 31 feet (90.3%) demonstrated excellent or good results. In group 2, we obtained 19 excellent (90.5%) and 2 good (9.5%) results. Group 1 had 6 excellent (60%), one good (10%) and 3 fair (30%) results.
Conslusion: Surgical treatment of the relapsed clubfoot with toe-in gait including soft-tissue release, tendon transfer and mid-foot osteotomy, along with SEROT in cases of severe toe-in gait, is effective in correcting residual clubfoot deformities.
