Iliac crest bone graft with radial forearm flap for thumb reconstruction: A case report

Traumatic thumb amputation is a serious injury that requires replantation or reconstruction. Toe-to-thumb transfers method have great survival and patient satisfaction in thumb reconstruction. Alternative method like Iliac Crest Bone Graft (ICBG) with flaps may help surgeons achieve maximum results. A 32-year-old male presented with occupational traumatic right thumb amputation. After initial debridement and K-wire installation, the thumb became necrotic. An ICBG with radial forearm flap was performed after the patient denied a toe-to-thumb transfer. Follow-up demonstrated viable flap, no infection, good joint mobility, and improved Kapandji and DASH scores. Osteoplastic reconstruction of the thumb using ICBG method is valuable for amputations around the metacarpophalangeal level preserving native anatomy and function. Radial forearm flaps are advantageous due to their thin, pliable and ability to preserve the radial artery. However, donor morbidity and potential complications should be considered. ICBG with radial forearm flap showed promising result.
