The Wartenberg syndrome , also known as Cheiralgia paraesthetica , is a nerve compression syndrome of the radial nerve with sensory disorders on the extensor ( dorso - ulnar ) side of the thumb, the extensor side of the index finger and in the first intermetacarpal space . The Wartenberg syndrome is named after Robert Wartenberg , who first described it in the 1930s.
root cause
The most common cause of Wartenberg syndrome is pressure damage to the sensitive parts ( ramus superficialis ) of the radial nerve . The cause of the pressure damage can be, for example, watch straps, bracelets, plaster casts or handcuffs that are too tight (hence the further description of the syndrome as arrestant paralysis or bondage paralysis ). In case series , it was found that some of the cases with a mellitus Diabetes is associated. In a further part of the cases, a strong strain on the wrist during work was found. Local trauma to the edge of the lower forearm on the thumb side, such as those caused by blows or cuts, can also lead to nerve damage.
diagnosis
The clinical symptoms already described are indicative of the diagnosis. Hoffmann-Tinel sign positive. The Finkelstein test can be positive, but is not pathognomonic for this disease. The electroneurography shows signs of damage to the superficial branch, it also serves the differential diagnosis carpal tunnel syndrome or further damage to the radial nerve excluded.
If the symptoms of Wartenberg syndrome are limited to pain and there are no sensory disturbances, the symptoms of tendovaginitis stenosans resemble de Quervain or intersection syndrome , which must also be included in the considerations for the differential diagnosis.
therapy
Primarily, conservative therapy with brief immobilization on a dorsal forearm cast , the use of NSAIDs and local steroid injections can be attempted.
