Abstract:

BACKGROUND: Accurate reduction and stable fixation after posterior pelvic ring injury are closely related to postoperative functional status.
OBJECTIVE: To investigate the clinical experience that M-shaped plate fixation for injuries at the posterior ring of the pelvis.
METHODS: The clinical data of 32 cases with posterior pelvic ring injury undergoing M-shaped plate were analyzed retrospectively. There were 22 males and 10 females, at age range of 18-51 years (mean 34.5 years). Fracture reduction was evaluated by Matta criterion and function was evaluated by Majeed functional scoring.
RESULTS AND CONCLUSION: The average intraoperative time was 1.5 hours (ranging from 1 to 2 hours), and the average intraoperative blood was 190 mL (ranging from 80 to 300 mL). There was no iatrogenic nerve injury and all the incisions healed during the primary procedure. All the patients were available at follow-up, with a mean period of 22 months (ranging from 8 to 36 months). According to Matta criterion for fracture reduction, the results were excellent in 24 patients, good in 6 and fair in 2, with excellence rate of 93.8%. According to the Majeed functional scoring, the results were excellent in 20 patients, good in 8 and fair in 4, with excellence rate of 87.5%. M-shaped plate fixation for posterior pelvic ring injury has the advantages of broad indications, simplicity of operator, short intraoperative time, small trauma, less bleeding, fewer complications, and significant clinical efficacy, which is worth spreading.
