OBG · Normal pregnancy: carpal tunnel syndrome
Sample itemA woman at 32 weeks has nocturnal tingling and numbness of the thumb, index and middle fingers, relieved by shaking the hand. What is the best initial management?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Night wrist splints in neutral position and reassurance
Fluid retention in pregnancy compresses the median nerve at the carpal tunnel, and symptoms usually resolve after delivery. Splints and reassurance are first-line, with steroid injection or surgery reserved for severe or persistent cases. Imaging is unnecessary for classical symptoms.
Option by option
A. Surgical decompression at once
Surgery is rarely needed in pregnancy.
B. Cervical spine MRI
Classical median nerve symptoms need no spinal imaging.
C. Oral prednisolone for 3 months
Prolonged systemic steroids are not appropriate for this self-limiting condition.
D. Night wrist splints in neutral position and reassurance (correct)
Correct. Conservative splinting is first-line and the condition usually resolves postpartum.
