The overlap pattern of the lateral antebrachial cutaneous nerve and the superficial branch of the radial nerve.
The anatomic relationship between the lateral antebrachial cutaneous nerve (LABC) and the superficial branch of the radial nerve (SBR) is outlined in 53 cadaver and 41 clinical dissections. Either partial or complete overlap of the LABC with the SBR occurred in 75% of the cases. The LABC and the SBR innervated separate territories in only 25% of the dissections. We suggest that injury to the LABC may be a concomitant finding in patients with injury to the SBR and that this associated injury to the LABC may be one of the reasons why neuromas of the SBR have been thought to be more resistant to therapy than neuromas elsewhere.
