Abstract：Objective To investigate the surgical approach and result of minimally invasive percutaneous plate osteosynthesis with a moulding locking plate for treatment of patients with posterior pelvic ring injury.Methods Forty-six patients (27 men,19 women; at mean age of 34.8 years) with posterior pelvic ring injury treated from January 2008 to December 2012 were enrolled in the study.There were 18 patients with type-C1.1,8 with type-C1.2,9 with type-C1.3,and 11 with type-C2 fractures according to Tile classification system.Treatments were all minimally invasive percutaneous plate osteosynthesis with a moulding locking plate.For the combined anterior pelvic ring injuries in 32 patients,additional surgical interventions included limited open reduction and internal fixation via the anterior approach (n =30) and cystostomy for urethral injury (n =2) ; for the combined acetabular fractures in 14 patients,additional surgical interventions included limited open reduction and internal fixation via the anterior approach (n =8) and open reduction and internal fixation via the Kocher-Langenbeck approach (n =6).Results There was no massive bleeding in operation and no lumbrosacral nerve entrapment syndrome,infection,reduction loss or deep vein thrombosis after operation.Reduction of the anterior-posterior pelvic ring injury was excellent for all patients at a mean follow-up of 19 months (range,8-35 months).Partial weight-bearing was permitted for all patients at postoperative 6-10 weeks and full weight-bearing at postoperative 12-16 weeks.Besides,X-ray films revealed bone callus formation through fracture line and bony healing in all patients.Conclusion Minimally invasive percutaneous plate osteosynthesis with a moulding locking plate gains advantages of rigid fixation,minor trauma,less bleeding,short operation time,and early ambulation and hence deserves wild attention in clinical practice.
