Summary
Distal posterior interosseous nerve syndrome causes chronic dorsal wrist pain. Surgical treatment, including nerve resection, effectively relieved pain in most patients.
Area of Science:
- Orthopedics
- Neurology
- Hand Surgery
Background:
- Chronic dorsal wrist pain can significantly impact quality of life.
- Distal posterior interosseous nerve syndrome is a less common cause of wrist pain.
Observation:
- Five patients with chronic dorsal wrist pain were diagnosed with distal posterior interosseous nerve syndrome.
- Clinical findings included tenderness in the fourth extensor compartment and pain reproduction with wrist extension/flexion.
Findings:
- A lidocaine block of the posterior interosseous nerve provided temporary pain relief.
- Surgical exploration revealed nerve enlargement or adhesion to the joint capsule in all patients.
- Nerve resection resulted in excellent pain relief and return to activity in four patients and improvement in one.
Implications:
- Surgical intervention for distal posterior interosseous nerve syndrome can be highly effective.
- Consider this diagnosis when other causes of dorsal wrist pain are ruled out.
- This study highlights surgical options for refractory wrist pain.
