|January 1, 1984
Summary
Submuscular transposition of the ulnar nerve effectively improved symptoms in most patients. Surgery demonstrated positive outcomes for nerve pain, numbness, and muscle weakness, even in severe cases.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Hand Surgery
Background:
- Ulnar nerve entrapment at the elbow can cause significant pain, numbness, and muscle weakness.
- Submuscular transposition is a surgical technique to decompress and reposition the ulnar nerve.
Observation:
- Forty patients (41 operations) with ulnar nerve issues underwent submuscular transposition.
- A grading system assessed preoperative and postoperative nerve tenderness, numbness, paresthesia, and muscle weakness.
Findings:
- 37 out of 41 operations showed improvement in the overall grade.
- 25 of 34 patients with preoperative muscle weakness experienced improvement.
- Five patients with severe intrinsic muscle weakness and clawing showed positive results.
Implications:
- Submuscular ulnar nerve transposition is an effective treatment for ulnar nerve entrapment at the elbow.
- The surgical technique provides reliable muscle reattachment, even in high-demand individuals like athletes.
- This procedure can restore function and alleviate symptoms in patients with moderate to severe ulnar nerve compression.
