INTRODUCTION: Nerve grafting with the sural nerve is a standard treatment method for radial nerve injury that requires another incision at the lateral ankle distal from the injured upper limb. The aim of this study was to investigate the common trunk (CTCB) of the inferior lateral brachial cutaneous nerve (ILBCN) and posterior antebrachial cutaneous nerve (PACN) as a possible donor inside the lateral intermuscular septum. MATERIALS AND METHODS: The arms and legs of 8 formalin-embalmed cadaver specimens were studied. The radial nerve, common trunk of the ILBCN and PACN, and the sural nerve were identified and measured in length and diameter. For histological examination, nerve samples from 6 fresh cadavers were harvested and processed for further axonal counting. RESULTS: The average length of the CTCB was 114.92 ± 18.9 mm. To match the diameter of the radial nerve at its proximal third, 3 cables of CTCB graft were necessary, which corresponds to a defect length of 3.8 cm. At the level of the distal third, the number of grafts was reduced to 2 with a corresponding defect length of 5.7 cm. The radial nerve contained 15162 ± 318 axons, and the CTCB comprised 3959 ± 176 axons. To match the axon count of the recipient nerve, 4 grafts of CTCB were necessary, which corresponded to a defect length of 2.8 cm. CONCLUSION: CTCB is a consistent and easily dissected cutaneous nerve branch of the radial nerve that can be used for bridging small gaps after neuroma-in-continuity in radial nerve palsy.
