Question 1 · Hard
After eight weeks of splinting and a steroid injection with little lasting relief, a patient shows thenar wasting, and EMG shows axonal loss with fibrillations in abductor pollicis brevis. What is the next step?
- ARefer to a hand surgeon for carpal tunnel release
- BContinue splinting for a further six months
- CAdd heavier grip strengthening
- DRepeat the steroid injection weekly
Show answerHide answer
Answer: A · Refer to a hand surgeon for carpal tunnel release
Thenar wasting and axonal loss mean severe compression with risk of permanent motor damage, and a failed conservative trial. Surgical decompression is indicated to protect nerve function. Delay worsens recovery.
- B: More splinting delays decompression in severe disease.
- C: Grip strengthening raises tunnel pressure.
- D: Repeated weekly steroid injections risk tendon damage.
Remember this
Thenar wasting or axonal loss with failed conservative care calls for surgical referral.
