Objective To investigate the advantages and effectiveness of ISO-C3D guided percutaneous sacroiliac joint screw internal fixation for treatment of pelvic posterior ring injuries by comparing with anterior opened reduction and reconstruction plate internal fixation. Methods A retrospective analysis was made on the clinical data of 54 patients with posterior ring injury treated between June 2013 and January 2016. Of 54 patients, 33 underwent ISO-C3D guided percutaneous sacroiliac joint screws internal fixation (group A), and 21 underwent anterior opened reduction and reconstruction plate internal fixation (group B). There was no significant difference in gender, age, cause of injuries, injury to operation time, fractures type, combined injuries, and injury severity score (ISS) between 2 groups (P > 0.05). The operation time, intraoperative blood loss, length of operative incision, hospitalization time, postoperative pain degree, reduction evaluation, and functional evaluation were compared between 2 groups. Results Group A was significantly better than group B in operation time, length of operative incision, and hospitalization time (P < 0.05). The intraoperative blood loss of group A (10-20 mL) was significantly less than that of group B[(524.1±160.1) mL]. All patients of the 2 groups were followed up 7 to 24 months with an average of 11.6 months. No injury of vessel or nerve occurred in group A; worse neurological symptoms of lower limbs and incision infection were observed in 2 patients of group B respectively, and the other patients achieved primary healing of incision. At 48 hours after operation, the visual analogue scale (VAS) score of group A (1.7±0.7) was significantly lower than that of group B (8.2±0.8) (t=-30.463, P=0.000). Radiological examination showed fracture reduction. According to the Matta score standard, the reduction results were excellent in 21 cases (63.6%), good in 10 cases (30.3%), and fair in 2 cases (6.1%) in group A; the reduction results were excellent in 16 cases (76.2%), good in 4 cases (19.1%), and fair in 1 case (4.7%) in group B; and there was no significant difference between 2 groups (χ2=0.961, P=0.618). Fracture or dislocation healed well in 2 groups, and the walking function was restored. According to the Majeed standard for evaluation, the results were excellent in 23 cases (69.7%), good in 9 cases (27.3%), and fair in 1 case (3.0%) in group A; the results were excellent in 14 cases (66.7%), good in 5 cases (23.8%), and fair in 2 cases (9.5%) in group B; no significant difference was shown between 2 groups (χ2=1.501, P=0.591). Conclusion Compared with anterior opened reduction and reconstruction plate internal fixation, ISO-C3D navigation percutaneous sacroiliac joint screw internal fixation is an ideal surgical method to treat pelvic posterior ring injury, with the characteristics of less trauma, less pain, precise screw implant and safety.
