Partial ulnar nerve transfer to the nerve to the biceps for the treatment of brachial plexopathy in metastatic breast carcinoma: case report.

Brachial plexus neuropathy can cause progressive pain and disability in patients with breast cancer. Metastatic spread and radiation injury are the most common causes in these patients. We report a case of partial ulnar nerve transfer to the nerve to the biceps muscle to restore elbow flexion in a patient with combined radiation-induced and metastatic brachial plexopathy.
