Cubital Tunnel Syndrome

Selected Features of Our Program

Evaluation and Diagnosis

Cubital tunnel syndrome is compression of the ulnar nerve at the level of the elbow. The condition is worsened by keeping the elbow bent for prolonged periods of time or leaning on it. As pressure builds up in the nerve, the fingers start to tingle and go numb. The hand gets weak; cramps, and can even start to drop things. Pain can run from the fingers, across the wrist, and up the forearm to the elbow or higher. These symptoms are often worse at night and wake patients up. This condition is often confused with carpal tunnel syndrome. Sorting out these differences is done by a specialist in nerve compression surgery and may include electrical nerve testing.

Treatment and Recovery

The entire non-surgical treatment program is based on two ideas: proper sleeping posture and correct daytime habits. Therapists teach patients ergonomically correct work habits, help to adjust workstations and equipment, and provide proper elbow padding. This works for most patients. If the measured nerve compression is severe enough, all non-surgical attempts have failed, or a special situation of excessive nerve mobility exists, then surgery is an option.

Most patients can be operated on with a less than one-inch incision for simple release of bands that compress the nerve. Special circumstances or more severe compression may indicate that the best solution is to shift the nerve into a healthy environment surrounded by the rich blood supply of good muscle. This is called a transposition. Both types of surgery are performed in less than 30 minutes as an outpatient. After surgery, a light soft dressing is placed over the region of the elbow. Patients are encouraged to use the hand right away with no formal restrictions. Hand therapists teach simple exercises that improve recovery, while patients are back to most activities in a month.
