This structure splits into two at the knee joint where its more distal extension inserts at the Gerdy tubercle. For 10 points each:
[10m] Name this thick band of fascia (“FASH-uh”) running along the lateral side of the thigh. Common diagnostic tests for overuse injuries involving this structure include Noble’s compression test and Ober’s distensibility test.
ANSWER: iliotibial band [or IT band or iliotibial tract or Maissiat’s band; accept iliotibial band syndrome or ITBS]
[10e] Runners suffering from IT band syndrome experience a characteristic sharp pain isolated to the lateral epicondyle of this long bone whose head rotates with the acetabulum.
ANSWER: femur
[10h] One candidate for the cause of pain in ITBS is the activation of this class of largest mechanoreceptor within a layer of fat deep to the IT band from compression. The concentric lamellae in these receptors show up in a distinctive whorl pattern in imaging.
ANSWER: Pacinian corpuscle [or lamellar corpuscle or Vater–Pacini corpuscle]
