38 Foot and Ankle Amputations: Ray Resections
1 BACKGROUND Malignant tumors of the foot present a significant and for-midable challenge to the orthopaedic oncologist due to thefoot s unique function and anatomic peculiarities. The foot is uniquely adapted for bipedal motion and assuch is essentially a tripod. The tripod is basically formed bythe first ray, the fifth ray, and the calcaneus and is supportedby the osseous configuration of bones in the midfoot thatform a Roman arch, which in and of itself is inherentlystable. Both bone and soft tissue contribute to the structure andfunction of the foot . Furthermore, the foot is composed ofcompact compartments that are interconnected by nerves andvascular structures. Complete resection (wide local excision) ofosseous structures of the foot is difficult because of the inter-ruption of these complex anatomic relationships, which affordstability to the foot , in addition to the interconnected compart-ments.
