Cubital tunnel syndrome is a common neuropathy of the upper extremity. Patient symptoms typically consist of numbness in the ulnar side of the side and hand intrinsic muscle weakness. Physical examination and EMG/NCV are usually adequate to establish a diagnosis. Nonoperative management works approximately 50% of the time and consists of rest and splinting. Operative management can help the symptoms and prevent progression of disease. During surgical decompression, all sites of potential compression should be evaluated to give the patient the best chance for a successful outcome.
