Sesamoiditis is inflammation of the sesamoid bones or surrounding structures beneath the first metatarsal head, commonly presenting in high-demand athletic patients.

Question 2

Freiberg's infraction (avascular necrosis) most commonly affects which metatarsal head?

Accepted Answer

Second

Answer

Freiberg's infraction most commonly affects the second metatarsal head due to its relative rigidity and repetitive stress concentration at that joint.

Question 3

Which clinical test is used to diagnose posterior tibial tendon dysfunction by assessing single-limb heel rise?

Accepted Answer

Single-heel rise test

Diabetic peripheral neuropathy of the foot is most commonly associated with which nerve fiber type loss?

Accepted Answer

Small unmyelinated sensory fibers (pain and temperature) first

Answer

Diabetic peripheral neuropathy typically affects small unmyelinated C-fibers (pain and temperature) first, progressing to larger fibers, following a 'stocking-glove' distribution.

Question 5

Which grading system is used to classify diabetic foot ulcers by depth and presence of infection or ischemia?

Accepted Answer

Wagner grading scale

Answer

The Wagner grading scale classifies diabetic foot ulcers from Grade 0 (intact skin at risk) to Grade 5 (whole-foot gangrene) based on depth, infection, and ischemia.
