[Choices of the internal fixation and approaches on unstable pelvic ring fractures].

Objective: To discuss the suitable surgical approach and the internal fixation of unstable pelvic pelvic fractures.

Methods: From May 2010 to May 2015, 45 patients with unstable pelvic fractures were treated with different approaches and fixations, including 38 males and 7 females with an average age of 45 years ranging from 21 to 61 years. The course was within 2 weeks. According to Young-Burg classification, 23 patients were lateral compression injuries, 6 patients were vertical shearing injuries, 16 patients were anterior-posterior compression injuries. All patients had hip pain and limitation of motion, the X-rays showed the pelvic ring fracture.

Results: All wounds healed well without complications, 45 cases were followed up for a mean period of 13 months (ranged 9 to 21 months). Patients with hip pain had a good postoperative pain relief. The post-operative X-rays showed the reduction was satisfied and the pelvic ring shaped well. According to Majeed standards, the final follow-up score was 93.5±11.6, 35 cases got excellent results, 8 were good, 2 were fare.

Conclusions: The unstable pelvic and acetabular fractures are always with compound injury. Beside the reduction, to decrease the second surgery trauma should take into consideration as well, the intra-articular reduction and the stability of the pelvic were especially valued, so combined the different approach with minimal invasive technique can get good clinical result.
