Cubital tunnel syndrome and the painful upper extremity

Cubital tunnel syndrome is the second-most-common compressive neuropathy. With the increasing prevalence of entrapment neuropathies, the presentation of ulnar nerve compression with a painful upper extremity appears to be more common. Although our knowledge and understanding of this disease are increasing, the principles of management remain constant. We are obliged to reach a timely and appropriate diagnosis to minimize the extent of neurologic injury and institute an appropriate treatment regimen to preserve and restore normal neural function. Although there are many ways to reach these goals, the avoidance of complications is paramount to achieve a reliable and pain-free outcome. Preventing injury to the medial antebrachial cutaneous nerve, complete release of all sites of compression, and avoidance of creating new compressive sites are the keys to this end.
