摘要

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.
