Preferred Practice Patterns1

Key Features


  • Pubic symphysis pain

  • Pain in the groin

  • Pain in the perineum

  • Pain often increases with weight bearing, sitting, side lying, transitional movements, and palpation of pubic symphysis

  • Pain may radiate to the anterior or upper thigh

Essentials of Diagnosis

  • Usually associated with excessive movement of the pubic symphysis

  • Difficulty with hip adduction and hip abduction

  • Waddling gait

  • MRI, x-ray, ultrasound

General Considerations

  • Pubic symphysis joint is capable of undergoing anatomical changes during pregnancy including widening of the interpubic gap, increased mobility, thickening of ligaments, and the appearance of gas in the joint2

  • Consider other pelvic girdle joints including sacroiliac (SI) joint and sacrococcygeal joint involvement

  • Athletic injuries

  • Rule out injury to hip including labral tear

  • Chronic condition may result in osteitis pubis; arthritis of the pubic symphysis joint


  • May occur during pregnancy, during delivery, or postpartum

  • One woman in 569 deliveries3 sustained a pubic symphysis injury

  • Estimated incidence of pubic symphysis separation during delivery is 1 in 300 to 1 in 30,000 pregnancies
