Pelvic bone loss may contribute to pelvic stress fracture after hip replacement surgery
Total hip replacement may affect the development of a type of pelvic stress fracture, sacral insufficiency fracture (SIF), suggests a study in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.
In particular, SIF appears more likely to occur on the side opposite from previous total hip arthroplasty (THA), according to the new research by Dr. Isabel Graul and colleagues of University of Jena, Eisenberg, Germany. The study also provides evidence that loss of bone density leading to SIF begins within the first postoperative year following THA.
Study suggests 'spatially different bone remodeling' across the sacrum following THA
Sacral insufficiency fracture occurs as a result of decreased bone mineral density in the sacrum. These fractures most commonly occur in older women, causing low back pain that worsens with activity. SIF is becoming increasingly common as the population ages and live longer, leading to more patients with osteoporosis.
