Objective To explore the clinical efficacy of antibiotic bone cement covered reconstruction steel plate in the treatment of infected anterior pelvic ring fracture.Methods From January 2017 to March 2022,11 patients with infected ante-rior pelvic ring fracture were treated with antibiotic bone cement covered reconstruction steel plate including 7 males and 4 fe-males and the age ranged from 27 to 49 years old.The pelvic fractures were classified according to the Tile typology:4 cases of Cl type,4 cases of C2 type,and 3 cases of C3 type.Among them,2 cases of infected anterior ring were infected after internal fixation of anterior ring,and 9 patients were infected with infected anterior ring due to incomplete early debridement,which was classified as infected according to the injury severity score(ISS)for 24 to 38 scores.The anterior ring was internally fixed by extended debridement,irrigation,and antibiotic bone cement covered reconstruction plate,and the posterior ring fractures were all closed reduction and internally fixed with sacroiliac screws.Results All 11 cases obtained follow-up from 13 to 20 months.A-mong them,2 patients had recurrence of postoperative infection,1 case was re-dissected and replaced with antibiotic bone cement-coated internal fixation,and 1 case had a milder infection without accumulation of the medullary cavity,and the infection was controlled by retaining the plate and replacing the antibiotic bone cement only after dissecting.Two cases developed incisional oozing,which healed after removal of the internal fixation three months postoperatively.All patients did not show pelvic fracture redisplacement or reinfection during the follow-up period.All 11 cases eventually healed bony.At the final follow-up,according to the Matta score,the fracture reduction was excellent in 6 cases,good in 4,and possible in 1.According to the Majeed functional score,it was excellent in 6,good in 3,and possible in 2.Conclusion Antibiotic bone cement covered reconstruction plate is ef-fective in the treatment of infected anterior pelvic ring fracture,with high intraoperative safety and low recurrence rate of infec-tion,which is conducive to the early postoperative rehabilitation and significantly shortens the course of the disease.
