Effects of minimally invasive plate-screw internal fixation in the treatment of posterior pelvic ring fracture.

Effects of minimally invasive plate-screw internal fixation and sacroiliac joint screw fixation in the treatment of posterior pelvic ring fracture were compared. Continuous selection of 20 cases of unstable pelvic posterior ring fractures, according to indications of operation, were divided into a group of 13 cases of plate-screw internal fixation and a group of 7 cases of sacroiliac joint screw fixation, and the operation effect and complications were compared. The comparisons of operation time, amount of radiation exposure, intraoperative blood loss, length of incision, partial load and full load time, and complications between two groups were carried out, and there were no statistically significant differences (P>0.05). The evaluation of clinical effects (based on the Majeed pelvic functional scoring criteria) and the evaluation of anatomic effects (based on Matta and Tornetta scoring criteria) between the two groups were compared, there was no statistically significant difference (P>0.05). Minimally invasive plate-screw internal fixation and sacroiliac joint screw fixation in the treatment of the posterior pelvic instability fracture both have indications and their therapeutic effects are equally matched.
