[Ulnar entrapment neuropathy].
Ulnar nerve entrapment is one of the most common entrapment neuropathies in the upper limb. The most frequent location of this syndrome is behind the elbow. The clinical picture is associated with the localization of the entrapment but usually consists of an altered sensation at the fourth and fifth digits and a weakness of the intrinsic muscles of the palm. The most constructive tool in making the diagnosis and in assessing the treatment's efficacy is the physical examination. Treatment alternatives depend on entrapment location. Conservative treatment options such as rest, a change in the work environment and patterns as well as splints are all accepted modalities. A lack of improvement following conservative treatment or a deteriorating nerve function is an indication for surgical intervention. This includes procedures comprised of decompression of the ulnar nerve alone or those which combine its transposition.
