Avulsion fractures of the anterior inferior iliac spine are rare injuries of
the pelvic ring and occur during sports activities. Hereby is presented a
case of a 22-year-old professional football player who was diagnosed to have
an avulsion fracture of the anterior inferior iliac spine on the right side
four months after the initial injury and he was treated surgically with the
excision of the avulsed fragment. The football player recovered completely
and returned to his usual sports activities. Two years later, due to the pain
in the hip an x-ray and MR image were made, which established the existence
of crescent formation, a heterotopic bone, in the area of the anterior
inferior iliac spine, which was surgically removed. Physical and medical
therapy was conducted and after four months, the professional athlete was
back playing football. Two years after the surgical excision of heterotopic
ossification, the patient was completely asymptomatic with the same ROM
without any thigh muscle hypotrophy, although isokinetic muscle testing did
show some weakness of the thigh extensor muscles. An x-ray did not show any
signs of heterotopic ossification.
