Abstract：Objective To evaluate the clinical efficacy of 3D image-guided and minimally invasive(percutaneous or mini-incision)hollow screw internal fixation in the treatment of fractures of pelvic Tilt.Methods A total of 28 patients with fractures of pelvic Tilt were treated with minimally invasive(percutaneous or mini-incision)hollow screw internal fixation from June 2015 to December 2016,and were analyzed retrospectively.According to the classification Tile,16 cases were Tile B2.1 type,6 cases were Tile B2.2 type,and 6 cases were Tile B3 type.Among them,22 cases were unilateral pubic upper extremity fractures,and 6 cases were bilateral pubic unilateral upper extremity fractures.Seventy cases in all sacral fractures were sacral DenisⅠtype,other 11 cases were sacral DenisⅡtype.The clinical effects were evaluated by the fracture reductions,final follow-up function scores of pelvic fracture and postoperative complications.Results All patients were followed,and the average follow-up was 6 months.According to the Matta standard,the qualities of fracture reduction of 22 cases were excellent,the qualities of 6 cases were good,and the excellent and good rate was 100％.According to the Majeed standard,the final follow-up results were 20 excellent cases,6 good cases,2 worse cases,and the excellent and good rate was 92.86％.None of patients were found pain,wound infection,nerve injuries,heterotopic ossification,thrombosis complications.Conclusion The 3D image-guided minimally invasive(percutaneous or mini-incision)hollow screw internal fixation in fractures of pelvic Tilt provides accuration,safety,shorter operation time,smaller wounds,fewer complications,and it is worthy of popularization and application.
