Numbness and tingling affecting the little and ring fingers
Cause
Compression of the ulna nerve as it goes around the elbow
Diagnosis
Numbness and tingling in the distribution of the ulna nerve
Weakness and wasting to the small muscles of the hand
Positive Tinnels (tapping) sign at the elbow
Nerve Conduction Tests can help but are often normal as the problem is usually intermittent
Treatment
Non Op
Splinting the elbow out straight
Operative
GA, Day Case
Simple Release
Incision on the inside of the elbow joint
Release of ‘Osbornes Ligament’ over the ulna nerve
Occasionally the nerve subluxes from its groove and needs to be transposed to the front of the elbow. This can be subcutaneous (beneath the kin) or submuscular (beneath the muscle).
Potential Complications
Infection, Haematoma
Nerve Injury
Incomplete recovery of the nerve
Post Op Care
Day Surgery
Bulky bandage for 10 days
Removal of sutures at 10 days
If simple release mobilise as comfortable
If transposition restrict elbow movement for 3-4 weeks
Surgical review at 10 days, six weeks and 3 months
