LONG-TERM RESULTS OF MORE THAN 700 OPERATIVELY TREATED CLUBFEET

Abstract

The purpose of this study was to evaluate the longterm results of 736 cases of operatively treated clubfeet, and to examine if there is any difference in the results between our patients and referred patients.

A follow-up examination was carried out in 736 cases of clubfeet operated on between 1966 and 1990. The average follow-up period was 14.7 years. Treatment was based on three pillars: well-organized care, conservative treatment and early operative treatment. In all of the reviewed cases, posteromedial soft tissue release was performed. Surgical intervention was indicated in cases of residual deformity after conservative treatment, cases of recurrent deformity, and cases of untreated clubfeet. Clinical evaluation contained the examination of residual deformities and the passive and active motions of the foot. In the radiological assessment, the anteroposterior talocalcaneal angle, the lateral talocalcaneal angle and the talometatarsal angle was measured.

In the clinical evaluations equinus deformity was found in 3.35%, varus in 7.23%, valgus in 8.55%, adducted forefoot in 30.8%, inflexion of the forefoot in 7.14%, and overcorrection to the vertical talus in 3.35%. Range of motion was normal in only 36% of the cases. Average anteroposterior talocalcaneal angle was 13.05 preoperatively and 22.13 postoperatively. Average lateral talocalcaneal angle was 10.78 preoperatively and 27.66 postoperatively. Average talometatarsal angle changed from 26 to 5.5 after the operation. The overall success rate of the operated cases was 65%.

After long-term follow-up, 65% of the cases were classified as successful. When comparing our patients with referred patients, there were considerable differences found in the rate of reoperation, age at the time of the first operation, and also in the results. These differences point out the importance of the early beginning of operative treatment, with regular follow-up and care.
