Pan ZH, Chen FC, Huang JM, et al. - This study sought to correlate the stability and clinical outcomes of modified pedicle screw-rod fixation (MPSRF) and anterior subcutaneous internal pelvic fixation (INFIX) for the treatment of anterior pelvic ring fractures using the Tornetta and Matta grading system and finite element analyses. The study enrolled a total of 63 patients, with an average age of 34.4 and 36.2 in the modified group and conventional group, respectively. For the treatment of unstable anterior pelvic ring fractures, both MPSRF and INFIX provide acceptable biomechanical stability. Nevertheless, MPSRF gives better fixation stability and a lower risk of implant failure, and can thus lead to better clinical outcomes. Thus, MPSRF should be more widely used for anterior pelvic ring fractures.
