Could severe anterior hip pain after a powerful soccer kick be a proximal rectus femoris avulsion injury?

Doctor’s answer

The direct head of the rectus femoris attaches to the anterior inferior iliac spine (AIIS), and the indirect head attaches above the acetabulum. During high-speed leg swings for kicking or long passes, sudden eccentric contraction can easily strain or avulse the proximal tendon or apophysis, accompanied by severe local pain, hematoma, and weakness in active hip flexion. Non-complete avulsions can be managed with weight-bearing restrictions, early brace protection, and gradual eccentric/isometric strength training rehabilitation; complete retracted tears (>2cm) or severe bone fragment displacement require surgical repair and fixation evaluation.
