Abstract:
Objective To investigate the clinical efficacy of open reduction and internal fixation with dynamic anterior plate-screw system for quadrilateral area ( DAPSQ ) in the treatment of elderly patients with acetabular fracture involving medial displacement of the quadrilateral surface. Methods Between January 2007 and December 2014, a series of 18 senile patients with acetabular fractures involving medial displace-ment of the quadrilateral surface were treated at our department. They were 13 men 5 women, with a mean age 67. 8 years ( range, from 61 to 78 years ) . By the Judet-Letournel classification, there were 4 anterior column fractures, 5 anterior column plus posterior hemitransverse fractures, 8 double column fractures and one T-shaped fracture. The delay from injury to surgery averaged 6. 5 days. All were treated with the technique of DAPSQ. Screw internal fixation of the quadrilateral area followed plate moulding via a single ilioinguinal ap-proach. Fixation with lag screws for the posterior column was added if necessary. Results The 18 pa-tients were followed up for 12 to 35 months ( mean, 26 months ) . By the Matta criteria for fracture reduction, 9 cases were rated as excellent, 6 as good and 3 as poor. Bone healing was achieved within 2 to 4 months( mean, 3. 5 months ) . By the modified Merle d'Aubigné & Postel criteria, the affected hips scored 9 to 18 points ( mean, 16. 3 points ) at the final follow-ups, giving 7 excellent, 7 good, 2 fair and 2 poor cases. By the Harris evaluation, the affected hips scored 58 to 98 points ( mean, 87. 6 points ) , giving 7 excellent, 8 good, one fair and 2 poor cases. The postoperative complications included urinary tract infection in one, lesion of lateral femoral cutaneous nerve in one, heterotopic ossification ( Brooker Grade Ⅰ) in one, and traumatic osteoarthritis in 5 cases 2 of whom had to receive total hip arthroplasty. Conclusion The technique of DAPSQ is suitable for the treatment of acetabular fractures involving medial displacement of the quadrilateral surface in elderly patients, because it can provide and maintain stable fixation of the fracture in the quadri-lateral area and preserve hip joint function, leading to fine outcomes.
