Joint replacement and peroneal nerve flap transfer repair surgery for deficiency in the fifth metatarsal bone of the right foot

Abstract

AbstractThe use of 3D printing technology for prosthetic treatment of forefoot bone defects is relatively uncommon. In December 2021, our research team successfully treated a patient presenting with a bone defect in the fifth metatarsal of the right foot, along with accompanying soft tissue and tendon defects. Following an initial debridement treatment, in April 2022, the patient underwent a right foot flap transfer repair. This procedure, performed under general anaesthesia, also included the implantation of a 3D‐printed titanium metatarsophalangeal joint replacement for the fifth toe. After a 12‐month post‐operative assessment, the donor site displayed normal characteristics and the affected foot exhibited a complete and intact appearance. The patient reported no pain or discomfort during weight‐bearing activities and exhibited a normal gait pattern without signs of limping. Both aesthetic and functional recovery outcomes were deemed satisfactory.
