Non-traumatic Pelvic Avulsion Fracture: Case Report.

ABSTRACT

Avulsion fractures of the anterior superior iliac spine are rare with a incidence 1.4% of pelvis injuries. This injury met commonly in adolescents, as an avulsion fracture of the apophyses, a result of suddenly and forcefully contraction or repetitive contraction of the sartorius and tensor fasciae latae muscles. Patients feel a severe pain localized in the anterior superior iliac spine on palpation and gait can be affected by pain. A high index of suspicion is necessary for emergency physicians to diagnose this rare injury. Treatment is mostly conservative although surgical treatment is required occasionally. We present a 46 years old man admitted to emergency department with a sudden pain on the right of pelvis after stumbling on the road. Avulsion fracture of anterior superior iliac spine detected by means of pelvis x-ray and computed tomography. Surgical intervention was preferred for this non-traumatic fracture due to bone displacement degree and milimetric exocytosis. Our case was unique according to patient’s age, trauma mechanism and treatment requirement as surgery.
