Subcutaneous rupture of the superficial branch of the radial nerve at the wrist. A case report and review of literature.
Isolated neuropathy of the superficial branch of the radial nerve (SBRN) is a rarely recognized pathology. It was initially described by Wartenberg in 1932. Various causes have been published. We report a case of an unusual injury of the SBRN at the wrist, never been previously reported in the literature. A 40-year-old woman presented with pain and paresthesia over the area of the lateral aspect of the wrist, thumb and first web two months after a blunt trauma of the left forearm. After failure of conservative treatment, surgical exploration found a neuroma of one branch of the SBRN. No distal nerve stump was found. Neuroma resection was performed and the nerve was transposed and embedded into the flexor pollicis longus muscle. With a six months follow-up, the result was satisfactory.
