Bilateral ulnar neuropathy at the elbow secondary to neuropathic arthropathy associated with syringomyelia.

Neuropathic arthropathy (NA), also known as Charcot joint, refers to a chronic progressive degenerative arthritis that is associated with an underlying central or peripheral neurologic disorder. The elbow is rarely reported to be involved in NA, but when affected, it is commonly a result of a cervical syrinx or tabes dorsalis. Few reports in the literature describe ulnar neuropathy at the elbow (UNE) associated with NA of the elbow, and none describe bilateral UNE in association with a cervicothoracic syrinx. We present a unique case of bilateral UNE resulting from NA of the elbow associated with a cervicothoracic syrinx.
