Summary
Post-operative ulnar nerve mononeuropathy can cause significant sensory and motor loss. Electrophysiological studies helped pinpoint the lesion location, with most patients experiencing partial or full recovery.
Area of Science:
- Neurology
- Neurosurgery
- Electromyography
Background:
- Post-operative ulnar nerve mononeuropathy is a rare complication.
- It presents with distinct sensory and motor deficits within the ulnar nerve distribution.
Observation:
- Four cases of severe sensory and motor loss exclusively in the ulnar nerve territory following surgery were analyzed.
- Clinical presentation and electrophysiological studies were meticulously documented.
Findings:
- Electrophysiological examinations, including nerve conduction studies and somatosensory evoked potentials, localized the ulnar nerve lesion.
- Lesions were identified at the wrist, arm, axilla, or brachial plexus, excluding the elbow.
- Full recovery was observed in one case, and partial recovery in two cases.
Implications:
- The findings support classifying these post-operative ulnar nerve lesions as neuralgic amyotrophy (Parsonage-Turner syndrome).
- This classification aids in understanding the etiology and predicting outcomes for such nerve injuries.
