ABSTRACT
Objective:
To evaluate the clinical results of miniplates combined with reconstruction plate in treating comminuted posterior wall acetabular fractures.Methods:
A retrospective case series study was conducted for 27 patients with comminuted posterior wall acetabular fractures treated in General Hospital of Central Theatre Command of PLA from October 2015 to June 2019. There were 18 males and 9 females, at age of 23-61 years[(45.9±10.9)years]. All patients were treated by using miniplates combined with the reconstruction plate. The operation time, intraoperative blood loss, intraoperative blood transfusion, length of hospital stay and time of fracture healing were recorded. The reduction quality was evaluated according to Matta radiographic standard at 2 days postoperatively. The modified Merle D'Aubigné-Postel score was adopted to evaluate the hip function at 3, 6 months postoperatively and the final follow-up. Postoperative complications were observed, and heterotopic ossification was assessed by Brooker grading standard.Results:
All patients were followed up for 12-48 months[36(24, 36)months]. The operation time was 123-242 minutes[(165.4±29.8)minutes]; the intraoperative blood loss was 170-550 ml[(358.3±111.3)ml]; nine patients required intraoperative blood transfusion of 300-500 ml[(377.8±66.7)ml]. The length of hospital stay was 12-29 days[(21.4±4.7)days]. The fracture healing time was 12-24 weeks[(16.3±3.0)weeks]. According to Matta radiographic standard, the reduction quality was excellent in 21 patients, good in 3 and poor in 3 at 2 days postoperatively, with the excellent rate of 89%. The modified Merle D'Aubigné-Postel score was 9-16 points[(13.1±1.9)points]at 3 months postoperatively, was 10-18 points[(15.4±2.0)points]at 6 months postoperatively, and was 12-18 points[(16.9±1.8)points]at last follow-up( P<0.01). The modified Merle D'Aubigné-Postel score between 3 months and 6 months was significantly different( P<0.01), and the difference between 6 months and the follow-up was statistically significant( P<0.01). The modified Merle D'Aubigné-Postel score was graded as excellent in 0 patient, good in 7, fair in 11 and poor in 9 at 3 months postoperatively, with the excellent rate of 26%; graded as excellent in 3 patients, good in 19, fair in 2 and poor in 3 at 6 months postoperatively, with the excellent rate of 81%; graded as excellent in 18 patients, good in 5, fair in 3 and poor in 1 at the last follow-up, with the excellent rate of 85%( P<0.01). No iatrogenic sciatic nerve injury, deep vein thrombosis or wound infection occurred after operation. No hardware loosening or loss of reduction occurred during the follow-up. The post-traumatic arthritis was identified in 2 patients. The avascular necrosis of femoral head was observed in 1 patient and thereafter underwent total hip replacement. The heterotopic ossification occurred in 3 patients, among which 2 patients were graded as Brooker class I and 1 as class II, but there was no adverse effect on hip function.Conclusions:
Miniplates combined with reconstruction plate in the treatment of comminuted posterior wall acetabular fractures have reliable fixation effect and attain good reduction, high fracture healing rate, less complications and satisfactory functional recovery.
