Neuropathies compressives du nerf ulnaire au poignet (et dans la main) et du nerf fibulaire commun. Données récentes

We report our experience with patients who underwent surgery for entrapment neuropathies involving the ulnar nerve at the wrist and into the hand and the peroneal nerve. For the ulnar nerve, the cause of the lesion was identified in all patients, generally a cyst which had developed in the Guyon canal. The patients usually recovered completely. For the peroneal nerve, there was a wide variety of causes, with mucoid cysts frequently involved. Recovery was often incomplete, because of the very marked initial axonal damage. We emphasized the need for rapid diagnosis and surgical treatment.
