Pararectus approach to the AO B2.2 pelvic fracture: early functional and radiological outcomes.

Purpose: The pararectus approach is used to treat acetabular fractures; however, it remains unclear whether it can be used to treat pelvic fractures. This study aimed to examine the outcomes of patients with a pelvic ring fracture treated with this approach. Methods: Seven patients with AO B2.2 pelvic fractures treated with the pararectus approach were included. Patients' pain was assessed pre- and postoperatively with a numerical rating scale. Radiological evaluations included inlet and outlet ratios and pelvic symmetry. Functional outcomes, including Merle d'Aubigné and Majeed scores, were also recorded for 12 months. Results: One patient experienced obturator nerve neuropraxia. Pain scores ranged from 2.3–8.0 to 2.0–3.1 points before and after surgery, respectively. Radiological findings revealed satisfactory outcomes. The maximal gap of the affected ilium reduced from 8.6–20.2 to 0–3.4 mm, from 6.8–17.9 to 0–4.4 mm, and from 3.7–20.3 to 0–3.2 mm in the axial, sagittal, and coronal views, respectively. Based on multiple evaluations, functional outcomes were improved for all patients. Conclusion: The pararectus approach can be used safely and satisfactorily to treat AO B 2.2 pelvic fractures.
