- Abstract:
- Background: Unstable pelvic ring fractures have a low incidence and are therefore rarely reported in the literature, especially regarding the relatively new method of lumboplevic fixation. After presenting the anatomy of the region and the most common classifications and therapies for pelvic ring injuries, the aim of the retrospective study described in this thesis is to evaluate the outcome of this surgical treatment within a larger study group and prolonged follow-up of at least 12 months. Methods: All patients that received lumbopelvic fixation at the Department of Orthopaedics and Trauma, Medical University Graz from January 2013 until October 2019, due to unstable pelvic ring fractures caused by trauma were retrospectively included. Patients had to be at least 18 years old and the fracture had to be classified as C-type fracture according to the AO/OTA classification. Fifty-three patients met the inclusion criteria. The author of this diploma thesis reviewed all medical records and original radiographic data retrospectively in a nonblinded fashion. Results: Thirty-nine out of 53 patients noted a disturbance. A disturbance was defined as: Pain in the region of the instrumentation, lack in range of motion or complications that led to hardware removal. Median length until disturbance was 236 days. In total, 81% of patients reached bony consolidation, within a median time of 267 days. Around 70% of patients requested hardware removal, due to disturbances or complications. In total, 18 patients had postoperative complications with 4 of them developing infection and 6 implant loosening or breakage. The group “No hardware removal” was older (mean=57), than the group with hardware removal (mean=41). Furthermore, 12 out of the 14 patients who did not experience disturbance by the implants were overweighted and/or older than 50 years. Conclusion: A CT-scan and hardware removal surgery may be scheduled in advance 12 months after lumbopelvic fixation surgery, since most of the patients will have achieved full bony consolidation and will have a disturbance up to this point. This strategy should especially apply to young and healthy-weighted patients.
