Preliminary results of iliosacral screws and plate combination in the management of tile B3 pelvic fractures: A retrospective case series.

Abstract

OBJECTIVE The aim of this study was to present preliminary results and experience with iliosacral screws and plate combination (horizontal triangular osteosynthesis, HTO) in the management of Tile B3 pelvic fractures. METHODS In this retrospective study, 26 patients (18 male, 8 female; mean age = 46, age range = 31-58 years) who were treated with horizontal triangular osteosynthesis using the combination of bilateral percutaneous iliosacral screws and transiliac plates due to Tile B3 pelvic fractures in our institution were included. The accompanying symptoms, blood loss, operation time , fracture healing time, and postoperative complications were observed and recorded. Patients were followed up retrospectively with routine post-operation visits for clinical and radiographic examination. The reduction quality was evaluated according to Matta criterion. Clinical and nerve function outcomes were evaluated by Majeed and Gibbons criterion. RESULTS The mean follow-up time was 15 months (range = 12-21 months). The mean blood loss and operation time were 24.6 ± 6.7mL and 30.5 ± 3.47 mins, respectively. Patients experienced early weight-bearing ability and no fracture reduction loss. Due to Matta criterion for fracture reduction, the results were excellent in 16 cases, good in 9 cases, and fair in 1 case. Due to Majeed functional scoring at the last follow-up, the results were excellent in 17 cases, good in 9 cases. Of 3 patients in whom neurologic impairment was detected preoperatively, 2 achieved complete recovery, and 1 achieved partial improvement postoperatively. CONCLUSION As a new surgical concept in the management of Tile B3 pelvic fractures, HTO seems to provide the following advantages: horizontal triangular fixation, minimally invasive incisions, less blood loss, and permitting early weight-bearing ability. However, there still exist several problems regarding the technique and the option of implants. LEVEL OF EVIDENCE Level IV, Therapeutic Study.
