‘Line of weight bearing falling anterior to the sacral promontory’ would indicate an abnormal spinal curvature which could be the cause or the result of
osteoarthritis. Some degree of
osteoarthritis is expected with age which can worsen post-menopause, being overweight, improper posture, lack of physical exercise/ muscle strength, chronic trauma, diabetes etc., which causes degeneration of the joint and associated inflammation that causes pain. The acute injury is unlikely to be related to it.
