Abstract:
Objective To explore the clinical efficacy of medial iliosciatic plating via the Stoppa approach for complex acetabular fractures involving the posterior column.Methods Between February 2015 and February 2016,a total of 16 complex acetabular facture cases treated by the medial iliosciatic plate via the Stoppa approach were retrospectively analyzed in this study.This approach provided good exposure to a large region of the pelvis and acetabulum including pubis symphysis,pubic ramus,anterior and inner wall of acetabulum,quadrilateral surface,inner surface of posterior column,true pelvic margin,greater sciatic notch and sacroiliac articulation.The anterior and column was reduced and fixed by the anterior column plate and the medial ilioseiatie plate.The screw direction and angle were adjusted according to the intraoperative X-ray.Surgical time,amount of bleeding,and relevant complications were recorded.The reduction of the posterior column fracture was evaluated by Matta scoring system on the plain X-ray of the pelvic post-surgery,and functional outcomes of the hip joint affected were evaluated one year post-surgery by the Merle d'Aubigne-Postel scoring system.All the cases were followed for at least 12 months.Results The reduction and fixation of the posterior column was accomplished in all the 1 6 patients.The average surgical time was 165.5 min (range,130-270 min).The average blood loss was 1 245.6 ml (range,600-5 600 ml).Thc intraoperative infusionof concentrated red blood cells averaged 6 units.According to the Matta scoring system,anatomical reduction was achieved in 12 cases,satisfactory reduction in 3,and poor reduction in one.The patients were followed from 12 to 22 months.According to the Merle d'Aubigne-Postel scoring system,there were 11 cases of excellent and 3 cases of good,yielding a good or excellent rate of 87.5％.The average Merle d'Aubigne-Postel score was 15.8 (range,8-18).There were 1 case of external iiiac vein rupture and 1 case of bladder rupture.Both were repaired during surgery.Superior gluteal artery rupture was found in 1 case and surgical ligation of the artery was performed during surgery.Conclusion In the treatment of complicated acetabular fractures involving the posterior column,the medial iliosciatic plating via the Stoppa approach is safe and effective,because it can provide a safe and sufficient operative field for surgeons to reduce and fix the posterior column fractures,and it leads to satisfactory recovery of the patients with limited complications.
