Summary
Anterior interosseous nerve syndrome (AINS) can mimic other conditions. This case highlights the importance of considering nerve topography for accurate diagnosis and treatment of peripheral nerve injuries.
Area of Science:
- Neurology
- Neurosurgery
- Clinical Electrophysiology
Background:
- Anterior interosseous nerve syndrome (AINS) is a recognized clinical entity.
- Diagnosis typically relies on characteristic electromyographic (EMG) findings and clinical presentation.
Observation:
- A patient presented with EMG findings localized to the anterior interosseous nerve distribution.
- However, subtle sensory deficits and median nerve conduction study abnormalities were atypical for isolated AINS.
Findings:
- Surgical exploration revealed a partial median nerve compromise at the antecubital fossa.
- The compromise predominantly affected nerve fascicles destined for the anterior interosseous nerve.
Implications:
- This case underscores the necessity of considering the internal topographical organization of peripheral nerves during lesion localization.
- Accurate localization is crucial for effective surgical intervention and patient outcomes in peripheral nerve disorders.
