Which test should be documented when evaluating lower-extremity injuries?

• A. Thompson
• B. Anterior drawer
• C. Lachman
• D. McMurray

Answer: (A)

Assessing Achilles tendon integrity is essential when there’s a lower-extremity injury. The test to document is the Thompson test. In a prone patient, squeeze the calf muscles and observe the foot. If the Achilles tendon is intact, the foot will plantarflex normally. If there is a rupture, the foot will not plantarflex or show markedly reduced plantarflexion. A positive Thompson test suggests Achilles tendon rupture, which needs urgent orthopedic evaluation and appropriate immobilization for management. The other tests target different structures: anterior drawer and Lachman assess knee ligament stability, and McMurray tests for meniscal tears. They’re not the primary tests for evaluating Achilles tendon integrity.
