CCEP Sports Injuries & Extremity Conditions Flashcards

Medial tibial stress syndrome (shin splints) is characterized by pain along which anatomical region?

Answer: Posteromedial tibial periosteum

MTSS involves stress and periosteal inflammation along the posteromedial tibial border from repetitive traction of the deep compartment muscles.

A baseball pitcher develops medial elbow pain reproduced by valgus stress testing. Which structure is most likely torn?

Answer: Ulnar collateral ligament

The UCL of the elbow is the primary restraint to valgus stress and is frequently torn in overhead throwing athletes requiring Tommy John surgery.

Which condition causes a snapping sensation on the lateral hip as the iliotibial band moves over the greater trochanter?

Answer: External snapping hip syndrome (coxa saltans externa)

Coxa saltans externa (external snapping hip) occurs when the iliotibial band snaps over the greater trochanter during hip flexion-extension movements.

Mallet finger deformity results from disruption of which structure at the distal phalanx?

Answer: Terminal extensor tendon insertion

Mallet finger is caused by avulsion or rupture of the terminal extensor tendon at the distal phalanx, leaving the DIP joint in a dropped, flexed position.

Which compartment of the leg is most commonly affected in acute compartment syndrome following tibial fracture?

Answer: Anterior

The anterior compartment of the leg is the most common site for acute compartment syndrome because it is tightly bounded by rigid fascia with limited expansion capacity.

A gymnast develops wrist pain at the distal radius. What is the most likely diagnosis given repetitive weight-bearing on the wrist?

Answer: Distal radius physeal stress reaction (gymnast's wrist)

Gymnast's wrist is a stress fracture or physeal stress reaction at the distal radius growth plate from repetitive compressive and shear forces during weight-bearing.
