S1094 EVALUATION OF CLUBFOOT- AT BIRTH AND LATER

Abstract

On the first to second day after birth, equinus, varus, forefoot adduction, calcaneopedal block derotation degree, reducibility characteristics, creases, cavus and muscle condition are evaluated using the clubfoot severity scale, and a long-leg cast is applied. Casting is preceded by the Ponseti treatment: the first ray is dorsiflexed while maintaining finger pressure on the talar neck just in front of the lateral maleolus in the external rotation and abductus. Immobilization is interrupted by redressive manipulation therapy depending on the clubfoot appearance and parents’ participation. Redressive manual and casting therapies typically provide good correction of the foot; yet the equinus persists in the majority of cases. The undercorrected equinus is the major reason for one-stage surgery, consisting of postero-medial-lateral release, capsulotomies and à-la-carte tendon elongation through the modified Cincinnati incision, done at the age of 7 to 9 months. As a rule forefoot derotation and heel fixation are not necessary. There are no skin problems or oedema, and the child usually stays in hospital only for one day after surgery. The outcome, however, is unpredictable even in a fully corrected foot. After surgery, the foot is regularly checked for a potential adductus, lack of dorsiflexion and cavus, and redressive therapy is promptly instituted. Any residual deformation resistant to conservative measures is treated surgically. In the long term, children should as a rule wear ordinary shoes. A typical reoperation – medial release with sectioning of the plantar fascia – is required in approx.10% of cases. Derotation below the knee and transposition of the tibialis anterior tendon are less frequent. At this Department, complete re-correction is required in less than 1% of cases.
