Necrosis Leading to Amputation Following Clubfoot Surgery

Abstract

Amputation after clubfoot surgery is a rare and catastrophic complication. This case report involves an amputation necessitated by postoperative necrosis on the medial side of the foot. To our knowledge, only one brief published report of necrosis following clubfoot surgery exists in the literature, and that report contains little clinical information. Although we know of several additional cases of necrosis following clubfoot surgery, the details of these cases remain unavailable to us for publication. The clubfoot deformity is almost always associated with vascular deficiencies involving the anterior tibial and dorsalis pedis arteries, as well as their derivatives. Since the area of necrosis in this case report coincided with the anatomic distribution of the derivatives of the congenitally reduced or absent dorsalis pedis artery, we suggest that insufficient blood flow to the dorsal and medial sides of the foot, and to the hallux contributed to the necrosis. In our opinion, the surgeon should assume that an abnormal vascular pattern, as described here, is present unless proven otherwise.
