Which condition is characterized by sesamoid pain beneath the first metatarsal head, often in dancers or runners?
Answer: Sesamoiditis
Sesamoiditis is inflammation of the sesamoid bones or surrounding structures beneath the first metatarsal head, commonly presenting in high-demand athletic patients.
Freiberg's infraction (avascular necrosis) most commonly affects which metatarsal head?
Answer: Second
Freiberg's infraction most commonly affects the second metatarsal head due to its relative rigidity and repetitive stress concentration at that joint.
Which clinical test is used to diagnose posterior tibial tendon dysfunction by assessing single-limb heel rise?
Answer: Single-heel rise test
The single-heel rise test assesses posterior tibial tendon function; inability to rise onto the toes on the affected limb suggests significant PTT dysfunction.
Diabetic peripheral neuropathy of the foot is most commonly associated with which nerve fiber type loss?
Answer: Small unmyelinated sensory fibers (pain and temperature) first
Diabetic peripheral neuropathy typically affects small unmyelinated C-fibers (pain and temperature) first, progressing to larger fibers, following a 'stocking-glove' distribution.
Which grading system is used to classify diabetic foot ulcers by depth and presence of infection or ischemia?
Answer: Wagner grading scale
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.
Haglund's deformity refers to a bony prominence at which location?
Answer: Posterosuperior calcaneal prominence
Haglund's deformity is a posterosuperior bony prominence of the calcaneus that can cause retrocalcaneal bursitis and insertional Achilles tendinopathy.
