Entrapment of the superficial branch of the radial nerve (Wartenberg's syndrome). A report of 52 cases.

We have treated 50 patients (52 cases) of entrapment of the sensory branch of the radial nerve in the forearm (Wartenberg syndrome) between January 1988 and July 1992. Conservative treatment achieved 71% excellent and good results. Operation was followed by 74% excellent and good results. The indications for each type of treatment are discussed. De Quervain's disease was associated in 50% of cases, and it is important to diagnose Wartenberg's syndrome before operating on the tenosynovitis in order to avoid unexpected postoperative complications and medicolegal problems.
