Conditions We Treat
Radial Tunnel Syndrome
What Is It?
Radial tunnel syndrome occurs when the radial nerve becomes compressed as it travels through the radial tunnel in the forearm near the outer elbow.
Unlike tennis elbow, this condition is nerve-related rather than tendon-related. Compression is often caused by repetitive forearm rotation, gripping activities, or prolonged muscle tension.
Symptoms
- Deep, aching pain along the outer elbow or forearm
- Pain worsened with forearm rotation or lifting
- Symptoms often mimic tennis elbow but feel deeper and more diffuse
- Typically no numbness or tingling
Diagnosis
- Physical examination with pain reproduced during resisted supination or middle finger extension
- Review of repetitive forearm activity history
- Nerve conduction studies and EMG when needed
- Ultrasound or MRI in complex cases
Treatment
Conservative Options:
- Activity modification and ergonomic adjustments
- NSAIDs for pain and inflammation
- Physical therapy focusing on nerve gliding, flexibility, and strengthening
Interventional Options:
- Ultrasound-guided radial nerve hydrodissection
Surgical Options:
- Surgical decompression if conservative treatment fails
