Pelvic stress fracture: Assessment and risk factors☆

Objective: To discuss the case of a patient with a pelvic stress fracture and the differential considerations among patients presenting with hip and/or groin pain. Features: A 42-year-old woman had hip pain after running. Initial radiograph of the pelvis was negative. Subsequent films showed a right inferior pubic ramus stress fracture. Stress fractures of the pelvis are relatively uncommon, accounting for only 1% to 2% of all stress fractures. Intervention and Outcome: Treatment included high-velocity, low-amplitude chiropractic manipulation, ultrasound, and stretching of the psoas and piriformis muscles. After 8 weeks, care was discontinued because the patient's hip pain had resolved. The pelvic fracture was left to heal with time. After 1 year, the patient still had delayed union of the fracture. Conclusion: When predisposing factors are present, such as osteoporosis and rheumatoid arthritis, pelvic stress fracture should be suspected in patients with groin or hip-area pain. However, because pelvic stress fractures are relatively rare, radiographic studies are often postponed, making diagnosis difficult. (J Manipulative Physiol Ther 2000;23:52–5)
