Summary
Compression of the lateral cutaneous nerve of the forearm (LCNF) causes elbow pain. Surgical decompression effectively relieved pain and restored function in most patients, with no recurrence.
Area of Science:
- Orthopedics
- Neurology
- Sports Medicine
Background:
- Compression of the lateral cutaneous nerve of the forearm (LCNF), a branch of the musculocutaneous nerve, can cause anterolateral elbow pain.
- This condition often results from strenuous elbow extension or forearm pronation, impacting daily activities and athletic performance.
Purpose of the Study:
- To evaluate the effectiveness of conservative and operative management for LCNF compression.
- To assess long-term outcomes, including pain relief, sensory recovery, and range of motion.
Main Methods:
- A retrospective study of 15 patients diagnosed with LCNF compression between 1965 and 1992.
- All patients initially received 12 weeks of conservative treatment.
- Surgical decompression involved resecting the aponeurosis overlying the nerve for patients not responding to conservative care.
Main Results:
- 11 out of 15 patients required surgical decompression.
- Operative treatment resulted in complete pain relief and full range of motion in all 11 patients, with no recurrence of hypesthesia.
- One nonoperative patient experienced persistent hypesthesia despite pain relief.
Conclusions:
- Surgical decompression by resecting the aponeurosis is a highly effective treatment for LCNF compression.
- Operative intervention provides durable pain relief and restores full function, significantly improving patient outcomes.
