ObjectiveThe aim of this study is to compare the clinical effects of percutaneous reconstruction plate and percutaneous sacroiliac screws in treatment of unstable posterior pelvic ring fracture.MethodsFifty-eight patients with unstable posterior pelvic ring fracture treated with two methods from March 2002 to October 2007 were enrolled in the study and divided into two groups according to two kinds of internal fixation: percutaneous reconstruction plate (20 males and 9 females, at mean age 37.3 ± 11.3 years) and percutaneous sacroiliac screws (21 males and 8 females, at mean age 39.3 ± 10.4 years). Causes of injury included traffic accident in 38 patients, fall from height in 17, and crush in 3. The correlative data of operation duration, number of X-ray exposures, intraoperative bleeding volume, length of incision, Majeed postoperative functional evaluation, and postoperative complications were analyzed statistically.ResultsAll 58 patients were followed up for 12-36 months (mean duration 21.3 months). There was statistical difference for operation duration, number of X-ray exposures, size of incision, and intraoperative bleeding volume between the two groups. Majeed postoperative functional evaluation indicated excellent and good rates of 86.1% for percutaneous reconstruction plate and 88.2% for percutaneous sacroiliac screws.ConclusionsThe clinical effect of the two methods is similar in treatment of Tile C pattern posterior pelvic ring fracture. However, the percutaneous reconstruction plate has lower risk of damaging nerves and blood vessels than the percutaneous sacroiliac screws. Moreover, intraoperative fluoroscopy is rarely performed.
