Abstract:
Objective To explore the design of a novel acetabulum anatomic locking plate and the clinical application for both column and quadrilateral surface fractures.Methods Clinical and follow-up data of 6 patients with both column fractures involving the quadrilateral plate managed operatively by a novel acetabulum anatomic locking plate from July 2014 to April 2015 were retrospectively analyzed.Among them 4 cases were male and 2 cases were female,with an average age of 35.1 years old (range,24-52 years old).The mean time from injury to operation was 7.2 d (range,2-12 d).According to the fracture classification of Letournel-Judet,there were all associated with two column fractures involving the quadrilateral plate..All patients managed operatively by the novel acetabulum anatomic locking plate,which can simultaneous manage both column and quadrilateral surface fractures through the single superior ilioinguinal approach.The image results by Matta standard were evaluated and the results of acetabular function after surgery were assessed by Merle d'Aubigne-Postel.Results The 6 patients were followed up for at least 14 months (range,12-22 months).Average blood loss was 860 ml,and average operative time was 286 min.The mean time of bony union was 4.3 months.According to the criteria described by Matta,66.7％ of the reductions were graded excellent,16.7％ were graded good,and 16.7％ were poor.Clinical outcomes (Merle d'Aubigne-Postel) at 12 months were 66.7％ excellent,16.7％ good,and 16.7％ poor.One patient (4.5％) had an iatrogenic injury of internal iliac artery during operation.Unilateral iliac artery embolization was performed.One patient had a fatty fluidization.No surgical site infection,femoral head avascular necrosis and traumatic arthritis occurred.Conclusion The novel acetabulum anatomic locking plates for both column and quadrilateral surface can provide strong and stable fixation for complex acetabular fractures through the single superior ilioinguinal approach.It can achieve satisfactory reduction and approving clinical functions.
