Abstract Objective: To evaluate the clinical outcomes of Internal fixator (INFIX) with iliolumbar fixation in treating vertically unstable pelvic fracture (Tile C). Methods: The clinical data of 5 patients with a vertically unstable pelvic fracture were treated with INFIX with iliolumbar fixation from May 2016 to April 2017 were retrospectively analyzed. There were 2 males and 3 females, aged from 29 to 65 years old with an average of (42.3±14.8) years. Among them, five fractures were classified as type C according to the classification of Tile. This fixation construct comprised a vertical lumbopelvic distraction component which fixed L4, 5 and the posterior superior iliac spine and percutaneous internal fixator using the vertebral pedical screwrod system which fixed anterior inferior iliac spine. Vertical displacement and functional outcome were evaluated by Matta method and Majeed score criteria respectively, and fracture healing time, nerve function, clinical function and complications were documented. Results: All the patients were followed up for 10 to 16 months. In the present clinical series, all fractures healed without significant loss of reduction. There were 3 excellent, 2 good according to the Matta criteria. There were 1 excellent, 3 good and 1 fair according to the Majeed score evaluation by the end of last follow-up visit. No iatrogenic complications of neurovascular injury occurred. Patients now walk unassisted without pain in the waist or legs, and with no shortening of lower limbs or claudication. Conclusion: INFIX with iliolumbar fixation that allows early mobilization and ambulation, with general applicability and definite safety, is an effective surgical technique for the treatment of vertically unstable pelvic fracture.

Key words： pelvic fracture, vertically unstable internal fixator iliolumbar fixation
