Simultaneous posterior and anterior interosseous nerve syndromes
The Journal of Hand Surgery
|July 1, 1982
Summary
A patient experienced simultaneous posterior and anterior interosseous nerve syndromes, showing denervation sensitivity to succinylcholine during anesthesia. Surgical repair led to full functional recovery of affected arm and hand muscles.
Area of Science:
- Neurology
- Orthopedic Surgery
- Anesthesiology
Background:
- Simultaneous posterior interosseous nerve (PIN) and anterior interosseous nerve (AIN) syndromes are rare.
- Understanding denervation sensitivity is crucial for anesthetic management in patients with nerve injuries.
Observation:
- A patient presented with concurrent PIN and AIN syndromes.
- During anesthesia induction, paralyzed muscles displayed hypersensitivity to succinylcholine, a neuromuscular blocking agent.
Findings:
- Surgical exploration and repair of a posterior interosseous nerve defect were performed.
- Post-operatively, complete functional recovery was observed in dorsal arm muscles, flexor pollicis longus, and pronator quadratus.
Implications:
- This case highlights the importance of recognizing denervation sensitivity in patients with peripheral nerve injuries.
- Successful surgical intervention can restore function in cases of combined PIN and AIN syndromes.
- Anesthetic protocols should be carefully considered in patients with neuromuscular compromise.
