Internal neurolysis and flexor tenosynovectomy: adjuncts in the treatment of chronic median nerve compression at the wrist in hemodialysis patients.

This retrospective clinical study reports our results with surgical treatment of chronic median nerve compression at the wrist in 27 hemodialysis patients with a mean follow-up of 22 months. Due to the high incidence of amyloidosis in our patient population, an extensive tenosynovectomy was done in all patients. Statistically significantly (P = .03) better results were obtained when a microsurgical internal neurolysis was added to the procedure, than simple decompression alone (82% vs. 63% good to excellent results).
