Efficacy analysis of steel plate internal fixation with external fixation to unstable pelvis

Objective To study the efficacy of steel plate internal fixation with external fixation to unstable pelvic.Methods 180 cases patients with unstable pelvic from March,2009 to March,2012 were studied.In accordance with the table of random numbers,they were randomly divided into three groups,each group had 60 patients.Internal fixation,external fixation or internal fixation with outside fixed surgical were used to patients.Results After treatment,the therapy clinical improvement excellent rate(93.3%) of internal fixation with external fixation group was significantly higher than the internal fixation group(68.3%) and the external fixation group(63.3%),comparison of three groups were statistically significant(P 0.05).After treatment,the wound healing time(9.9 ± 2.6 weeks) of internal fixation with external fixation group was significantly shorter than the internal fixation group(14.8 ± 2.2 weeks) and external fixation group(14.4 ± 2.8 weeks),the incidence of postoperative complications(15%) was significantly lower than the internal fixation group(11.7%) and the external fixation group(5%),three groups were statistically significant(P 0.05).Conclusions The steel plate internal fixation with external fixation of unstable pelvic has significant effect,and is significantly better than the separate use of internal fixation or external fixation.
