Ulnar Nerve Entrapment: Conservative & Surgical Treatment Options

Treatment progresses from conservative to surgical based on severity and response.

Conservative (First-Line)

• Activity modification: Avoid prolonged elbow flexion, pressure on medial elbow.
• Night splinting: Elbow extension splint or towel wrap prevents flexion during sleep.
• Ergonomics: Headset, padded elbow rests, workstation adjustment.
• Physical therapy: Nerve glides, ulnar nerve mobilization, strengthening (intrinsics, forearm).
• NSAIDs: For inflammatory component.
• Corticosteroid injection: Around (not into) nerve at cubital tunnel; limited evidence, risk of nerve injury.

Surgical (If Conservative Fails ≥3–6 months or Progressive Deficit)

• Cubital tunnel release (in situ decompression): Most common; opens roof of tunnel.
• Ulnar nerve transposition: Subcutaneous, intramuscular, or submuscular—moves nerve anterior to medial epicondyle.
• Medial epicondylectomy: Removes bony compression point.
• Guyon’s canal release: For wrist-level entrapment.
• Nerve repair/graft: For axonotmesis/neurotmesis.

Outcomes

85–95% improve with surgery; sensory recovery better than motor. Early decompression (before fixed weakness/atrophy) yields best results.
