Summary
Posterior antebrachial cutaneous (PABC) neuropathy is a rare condition. Sensory nerve conduction studies are valuable for diagnosing PABC neuropathy, as demonstrated in two patient cases.
Area of Science:
- Neurology
- Peripheral Nerve Disorders
- Surgical Complications
Background:
- Posterior antebrachial cutaneous (PABC) neuropathy is an uncommon condition.
- Understanding its causes and diagnostic methods is crucial for effective patient management.
Observation:
- Two cases of PABC neuropathy are presented.
- Case 1: Traction injury during humeral fracture reduction.
- Case 2: Injury associated with myocutaneous flap surgery.
Findings:
- Both patients exhibited reduced sensation in PABC nerve territories and a positive Tinel's sign.
- Sensory nerve conduction studies revealed reduced compound nerve action potential (CNAP) amplitude and slow sensory nerve conduction velocity (SNCV) in Case 1.
- Absent CNAP was noted in Case 2.
Implications:
- Sensory nerve conduction testing is a reliable method for confirming PABC neuropathy.
- These findings highlight potential iatrogenic causes of PABC neuropathy.
- Early diagnosis through nerve conduction studies can guide appropriate treatment strategies.
