Abstract

The aim of the study was the evaluation of both the foot correction and foot lengthening obtained using the distraction method with osteotomies versus distraction after the transverse tarsal joint resection. Ten patients (10 feet) aged from 5 years to 24 years (average, 10.5 years) were analyzed. Seven of them were treated for severe equinovarus deformity: six of congenital and one of posttraumatic etiology. In three patients, the indication for treatment was foot shortening due to hypoplasia with tibial shortening, combined with foot deformity. Preoperative shortening of the foot ranged from 1.5 cm to 10 cm (average, 4.5 cm). In four patients, osteotomy between the tarsometatarsal and transverse tarsal joints was carried out. In two cases, 'V-shaped' osteotomy through the hindfoot and midfoot was performed. In the remaining four patients, wedge resection of the transverse tarsal joint was performed. The follow-up was a mean of 32 months (range, 12-55 months). It was observed that foot lengthening after transverse osteotomy of the midfoot is difficult and unpredictable, because of distraction at the adjacent joints level instead of osteotomy site. The greatest lengthening of the foot (mean, 4 cm) was observed in the patients with the transverse tarsal joint resection. It was concluded that the transverse tarsal joint resection following callus distraction in the place of the resected joint is the effective method for foot lengthening, which can be combined with deformity correction.
