Ulnar Nerve Entrapment Guyon Canal
What is Ulnar Nerve Entrapment in Guyon Canal?
This condition involves compression of the ulnar nerve as it passes through Guyon’s canal at the wrist.
- Results in pain, numbness, and weakness in the hand
- Often affects athletes or manual laborers
Overview of the Condition
Symptoms are caused by nerve compression leading to sensory and motor deficits in the ulnar nerve distribution.
Symptoms
- Numbness in the ring and little fingers
- Weakness in hand grip
- Pain at the wrist
Causes
Repetitive pressure, trauma, or anatomical variations can lead to compression of the ulnar nerve in Guyon’s canal.
Diagnosis
Diagnosis is made using clinical examination, nerve conduction studies, and sometimes imaging.
Treatment Options
- Activity modification and splinting
- NSAIDs and corticosteroid injections
- Surgical decompression if conservative measures fail
Conservative Management
Initial treatment includes rest, wrist splinting, and anti-inflammatory medications.
Rehabilitation Exercises
- Wrist and forearm stretching
- Strengthening exercises for hand muscles
- Nerve gliding exercises
Surgical Options
Surgical decompression of Guyon’s canal may be performed if symptoms persist.
Anatomy Overview
Guyon’s canal is a narrow passage at the wrist through which the ulnar nerve travels.
Affected Areas
- Wrist, particularly the ulnar side
- Hand (ulnar nerve distribution)
