carpal tunnel - 2024 ACF Winter at UBC

Question

High rates of secondary radiculopathy in patients with damage to this region led Upton and Thomas to propose their controversial double crush syndrome theory. For 10 points each:

[10h] Name this region of the body surrounded by the pisiform, hamate, scaphoid, and trapezium bones as well as the flexor retinaculum. Compression of the median nerve in this region can lead to pain and numbness.

ANSWER: carpal tunnel [accept carpal tunnel syndrome]

[10e] Repetitive hand motions like playing instruments can cause these structures to swell and compress the median nerve, leading to carpal tunnel syndrome. These collagen structures connect bones to muscles, unlike ligaments.

ANSWER: tendons [or sinews]

[10m] Carpal tunnel syndrome can also result from this condition that leads to swan neck deformities and ulnar deviations. Symptoms in this condition are caused by autoimmunity, unlike a similarly-presenting “osteo” form.

ANSWER: rheumatoid arthritis [or RA; prompt on arthritis; reject “osteoarthritis”]
