Abstract
Objective
We reviewed clinical results with minimally invasive method and using a new developed plate for unstable pelvic ring fractures, especially vertically unstable sacral fractures.
Materials & Methods
Between 2002 and 2010, 35 patients with vertically unstable sacral fractures were treated with minimally invasive method and using an M-Shaped transiliac plate which was developed by the author. This plate is anatomically designed for posterior pelvic ring, and achieved rigid fixation. Patients included 19 male and 16 female, with the mean age of 46.2 (range, 17∼79) years old. According to the AO classification, 23 patients had a C1 injury, 9 had a C2 fracture, and 3 patients sustained a C3 injury of the pelvic ring. Functional outcome was assessed using the Majeed's functional evaluation and radiography. Minimum follow-up was one year.
Results
All patients were not fixed anterior of pelvic ring. The average of surgical time was 85 minutes (range: 45∼150), and intraoperative blood loss was 332.8 ml (range: 35∼1055). Postoperative functional results were excellent and good in 30 patients (85.7 %), and fair in four cases due to infection or sciatic nerve paralysis, and one case of poor was nonunion. Three patients complicated wound healing delayed, but there were no residual pain and re-displacement.
Conclusion
Using an M-Shaped transiliac plate can be achieved significant outcome and rigid fixation with minimal invasion for vertically unstable sacral fractures.
