In tibioperoneal tenoplasty, the tibialis anterior is transplanted through a subcutaneous tunnel from above the ligamentum transversum to the outer aspect of the dorsum of the foot. In its new location, it is sutured to the distal portion of the peronaeus longus, which has previously been severed above the outer malleolus. The pronatory action of the intact peronaeus brevis is strengthened by the attachment to it of the proximal portion of the severed peronaeus longus. The purpose of this operation is to correct the muscle imbalance and, thereby, to maintain the corrected position of the congenital club-foot and to prevent recurrences.
Sixteen feet were operated upon by the author between July 1, 1949, and November 24, 1954, the following results being obtained: one poor, two fair, five good, and eight excellent. In no case did hypercorrection occur as a result of overaction of the transplanted muscle, and there were no adhesions around the tendons, no failures of sutures, and no instances of postoperative pain in the foot.
