Abstract
BACKGROUND: The optimal surgical approach for managing AO type B2.2 pelvic ring injuries remains a topic of debate. This retrospective cohort study aimed to compare perioperative, radiographic, and short-term functional outcomes between the pararectus (P group) and lateral window (L group) approaches. METHODS: A total of 65 patients (27 in the P group, 38 in the L group) treated between 2017 and 2021 were evaluated. Postoperative pelvic symmetry and fracture gap reduction were assessed using the Matta/Tornetta criteria, Lefaivre criteria, inlet/outlet ratios, and multiplanar computed tomography. Functional recovery was measured using the Merle d'Aubigné hip score and Majeed pelvic score at 3, 6, and 12 months postoperatively. RESULTS: Radiographic parameters and fracture gap reduction were similar between the groups. However, the P group demonstrated significantly greater improvements in functional scores at all time points (p < 0.01). CONCLUSION: Our findings suggest that while both approaches provide satisfactory radiological outcomes, the pararectus approach may facilitate superior short-term functional recovery in patients with AO B2.2 pelvic ring injuries.
