An analysis of residual deformity in club feet submitted to early operation.
The contributions made by metatarsus primus varus, medial subluxation of the navicular, and angulation of the neck of the talus to the residual deformity in treated club feet were assessed from radiographs. Their relation to the appearance of the feet, to the age of the patient, to the results of operations, and to the age at the time of the first operation were investigated. Lateral rotation of the ankle and flattening of the talus were also studied. Medial subluxation of the navicular was found to be the most important factor influencing both the appearance of the feet and the lateral rotation of the ankle. Relocation of the talonavicular joint correlated with the success of operative treatment; and the timing of the primary operation determined the degree of relocation which could be achieved. Metatarsus primus varus and angulation of the talus were of little importance. Increased emphasis is given to the need for early relocation of the talonavicular joint.
