The cheilectomy ( Greek χείλος cheĩlos lip) is a surgical procedure in the field of orthopedic surgery or foot surgery. It is a joint-preserving procedure that is used in mild forms of osteoarthritis of the metatarsophalangeal joint of the big toe. Here, osteophytes ( osteophytes ) that have arisen in the course of osteoarthritis are removed, especially on the stretch side ( dorsal ) on the head of the first metatarsal head, in order to improve the mobility of the joint and reduce pain.
