Fixation of anterior pelvic ring fracture with long reconstruction plate combined with MIPPO technique / 中国骨伤

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of long reconstruction plate combined with minimally invasive percutaneous plate osteosynthesis(MIPPO) technique in the treatment of unstable pelvic anterior ring fractures.@*METHODS@#From January 2013 to February 2019, 16 patients with unstable pelvic fracture were treated, including 12 males and 4 females, aged from 20 to 60 years(mean 46.5 years). According to Tile classification, there were 4 cases of type B1, 6 cases of type B2, 4 cases of type C1 and 2 cases of type C2. The fracture of all patients was closed, and the time from injury to operation was 7 to 10 days with an average of 6.2 days. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, complications and limb function during the final follow-up were evaluated in 16 patients.@*RESULTS@#All 16 patients were followed up for 12 to 23 months (mean 19.1 months). The operation time was 60 to 180 min (mean 107.8 min). The intraoperative blood loss was 120 to 600 ml (mean 368.1 ml). The fracture healing time was 12 to 20 weeks (mean 16.3 weeks). According to Matta criteria, the fracture reduction was excellent in 6 cases, good in 8 cases and fair in 2 cases. One patient suffered from lateral femoral cutaneous nerve injury during the operation, and the lateral thigh sensation decreased after operation, which recovered after 6 months. One patient had pain stimulated by internal fixation at the iliac fossa. The symptoms were improved after the internal fixation was removed. The fractures of 16 patients were healed satisfactorily and there was no internal fixation loosening. Majeed score at the final follow-up was 67 to 95, excellent in 10 cases, good in 4 cases and fair in 2 cases.@*CONCLUSION@#Closed reduction and fixation of pelvic anterior ring fracture with long reconstruction plate combined with MIPPO technique through anterior approach has the advantages of less injury, less bleeding time during operation, saving operation time, high intraoperative safety, high fracture healing rate, early functional exercise after operation, and effective treatment of pelvic anterior ring fracture.
