Stabilization of sacroiliac joint disruption with threaded compression rods.
Eleven cases of sacroiliac dislocation and/or fracture (Malgaigne pattern) were successfully reduced and stabilized using two threaded compression rods. The mean follow-up period was 26.1 months (range, seven to 45 months). None of the implants failed and there was no subsequent displacement. Two patients had mild residual lower back pain, and one was treated with implant removal without subsequent relief of pain. One patient, in whom the operation was done 110 days after dislocation, had extension of an incomplete preoperative peroneal nerve palsy. After anterior pelvic ring stabilization has been performed, two threaded 3/16-inch diameter rods are driven from the normal posterior iliac wing superficial to the sacrum and through the reduced opposite iliac wing. Compression is obtained with washers and nuts. This procedure can be performed safely and effectively, providing stable fixation and allowing early mobilization to help lessen or prevent the complications associated with prolonged bed rest.
