Ulnar Neuropathy at Elbow (Cubital Tunnel Syndrome), Right Arm

ICD-10 Code
G56.21_3

Compression of the ulnar nerve at the elbow (cubital tunnel) in the right arm, causing numbness/tingling in the small and ring fingers.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with a chief complaint of intermittent paresthesias and numbness involving the right small and ring fingers. Symptoms are exacerbated by prolonged elbow flexion and leaning on the elbow. Denies neck pain or radiation. No history of trauma. Symptoms interfere with sleep and daily activities.

Clinical Examination Findings

Right upper extremity exam: Inspection reveals no obvious muscle atrophy of the hypothenar eminence or interossei. Tinel's sign at the right cubital tunnel is positive. Elbow flexion test is positive, reproducing paresthesias in the ulnar nerve distribution within 60 seconds. Sensation to light touch is diminished in the 5th digit and ulnar half of the 4th digit. Motor strength is 5/5 in all muscle groups, including the first dorsal interosseous.

Treatment Protocol

Conservative management initiated: Nighttime elbow extension splinting, activity modification to avoid sustained elbow flexion, and avoidance of direct pressure on the ulnar nerve. NSAIDs as needed for discomfort. Referral for EMG/NCS to assess nerve conduction velocity. Follow-up in 4-6 weeks to evaluate for clinical improvement or need for surgical decompression.
