Figure 4. Modified Doi procedure for two-stage double free functional gracilis transfer. A) Stage 1 transfer, innervated by a SAN transfer, attempts to restore elbow flexion and wrist extension. B) Stage 2 transfer, innervated by ICN 5-6, augments elbow flexion while adding finger flexion. Additional ICN 3-4 transfers are performed for triceps neurotization. Copyright Permission: Bishop AT.
