Typical Mechanism: Often results from acute overstretching during forceful hip abduction, especially common in sports involving rapid directional changes (soccer, hockey).
Sonographic Appearance: Look for disruption of muscle fibers, hematoma formation, hypoechoic gaps, and loss of the normal pennate muscle pattern. Fluid collections may be evident between disrupted fibers.
Key Anatomical Landmark: Evaluate carefully at the musculotendinous junction, located near the pubic attachment; tears frequently occur proximally.
Dynamic Assessment: Utilize gentle active and passive hip abduction and adduction during ultrasound to confirm tear presence, assess fiber discontinuity, and distinguish partial from complete tears.
