Abstract

Cubital tunnel syndrome with intrinsic muscle atrophy in elderly patients occasionally fails to respond to surgical decompression of the entrapped nerve. It is believed that severe irreversible changes due to prolonged nerve entrap-ment or insufficient decompression of the nerve are frequently responsible for the persistent symptoms and occasional cervical radiculopathy. However, magnetic resonance imaging (MRI) often reveals spinal cord segment compression at the C5/6 intervertebral space, where the C8 spinal cord segment is located, instead of C8 root compression at the C7/T1 intervertebral level in patients with persistent ulnar entrapment neuropathy. We studied ulnar nerve palsy with cervical spinal cord compression utilizing various kinds of evaluation methods to assess whether the cubital or cervical lesion was more responsible for the symptom.
