Which test is described to detect deformities by checking for crunching sounds?

• A. Squeeze Test
• B. Tinel Sign
• C. Apprehension Test
• D. Lachman Test

Answer: (A)

When a deformity or fracture is suspected, crepitus—an audible or palpable crunching/grinding sensation as bone ends rub or move—is a key clue. The squeeze test uses axial compression along the limb to provoke that movement and reveal any crepitus, which points to a fracture or displaced bone. The other tests assess different things: Tinel Sign checks for nerve irritation by tapping over a nerve; Apprehension Test looks for fear or guarding indicating joint instability or dislocation; Lachman Test evaluates ACL integrity by translating the tibia forward. None of those focus on producing or detecting bone crepitus, so the squeeze test is the best choice for detecting deformities via crunching sounds.
