Internal fixation, external fixation and conservative treatment for unstable pelvic fractures:callus growth and fracture healing rate / 中国组织工程研究

ABSTRACT

BACKGROUND:There are many methods in the clinic to treat pelvic fractures, mainly conservative treatment, internal fixation and external fixation. Conservative treatment often causes complications due to poor reduction after fractures. Fixation has good effects on repair of unstable fractures, but fixation is seldom used for pelvic fractures. OBJECTIVE:To observe the effects of internal fixation on unstable pelvic fractures, and compare with conservative treatment and external fixation. METHODS:126 cases of unstable pelvic fractures from Longhua District People’s Hospital of Shenzhen City from January 2008 to June 2014 were divided into three groupsconservative treatment group, external fixation group and internal fixation group (n=42). After treatment, patients received X-ray examination. Lindahl imaging criteria were used as evidence. The quality of fracture reduction was evaluated. Patients were regularly fol owed up after treatment. The recovery of limb function was evaluated according to Majeed standard. Repair effects, the excel ent and good rates of fracture healing and cal us growth were evaluated in the last fol ow-up. RESULTS AND CONCLUSION:During the last fol ow-up, the total efficiency was 81%in the internal fixation group, 69%in the conservative treatment group, and 71%in the external fixation group, and results were significantly better in the internal fixation group than in the other two groups (P<0.05). The Lindahl and Majeed scores were significantly higher in the internal fixation group than in the other two groups (P<0.05). These results suggest that internal fixation for unstable pelvic fracture obtained better recovery effects and efficiency than conservative treatment and external fixation. Thus, the internal fixation is more suitable for patients with unstable pelvic fractures.
