Treatment of unstable pelvic posterior ring fracture with percutaneous reconstruction plate and percutaneous sacroiliac screws: a comparative study
【摘要】：Objective:The aim of the study was to compare the clinical effects of percutaneous reconstruction plate and percutaneous sacroiliac screws in treatment of unstable pelvic posterior ring fractures. Methods:Fifty-eight patients with unstable pelvic posterior ring fractures treated with two methods from March 2002 to October 2007 were enrolled and divided into two groups according to two kinds of internal fixation: percutaneous reconstruction plate (20 males and 9 females, at mean age of 37.3±11.3 years) and percutaneous sacroiliac screws (21 males and 8 females, at mean age of 39.3±10.4 years). The injury causes included traffic accident in 38 patients, fall from height in 17 and crush in 3. The correlative data of the operation duration, time of X-ray exposure, intraoperative bleeding volume, length of the incision, postoperative functional evaluation of Majeed and postoperative complication were analyzed statistically. Results:All 58 patients were followed up for 12-36 months (mean duration of 21.3 months). There was statistical significant among the operation duration, times of X-ray exposure, length of the incision, intraoperative bleeding volume between two groups. The postoperative functional evaluation of Mejeed indicated excellent and good rates of percutaneous reconstruction plate for 86.1% and percutaneous sacroiliac screws for 88.2%. Conclusion:The clinical effect of two methods was similar in treatment of Tile C pattern of the pelvic posterior ring fracture. However, the risk damaging nerves and blood vessels in percutaneous reconstruction plate was less than that in percutaneous sacroiliac screws. Moreover, the intraoperative fluoroscopy is rarely performed.
