abstract

  • The paraglenoid sulcus is a variable groove in the ilium adjacent to the inferior end of the sacroiliac joint. This study investigates the hypothesis that the groove is due to resorption at the insertion of the anterior sacroiliac ligament in response to stress. The anatomical relationships of the groove are shown with plain films, arteriography and computed tomography. Relationship to parity was tested in 70 adult female subjects; a statistically significant relationship was found, with deep grooves occurring only in parous women. An association with osteitis condensans ilii was also demonstrated. Relationship to lumbosacral posture was tested in 102 adult females, and an association with increased lumbar lordosis was found. These findings are consistent with our initial hypothesis.
