Patients of unilaterally displaced sacral fractures fixed with lumbopelvic technique or novel adjustable plate from June 2011 to June 2017 were recruited into this study and were divided into two groups: group A (lumbopelvic fixation) and groups B (novel adjustable plate). Surgical time, intraoperative blood loss, frequency of intraoperative fluoroscopy, reduction quality, related complications were reviewed. Fracture healing was assessed by the radiographs conducted at follow-up. Functional outcome was evaluated according to the Majeed score at the final follow-up.

Patients of unilateral displaced sacral fractures from June 2011 to June 2017 were recruited into this study. The inclusion criteria were as follows: 18-65 years, with normal activity ability before injury, fixed with lumbopelvic technique or novel adjustable plate, completed more than a year follow-up. The exclusion criteria were as follows: pathologic fractures, open fractures, associated with other severe injuries (traumatic brain injury), risk factors affecting bone healing (osteoporosis, smoking, and metabolic diseases) and non-completion of one-year follow-up. Surgical time, intraoperative blood loss, frequency of intraoperative fluoroscopy, related complications were reviewed. Reduction quality was assessed on the postoperative radiographs and CT scans. Functional outcome was evaluated according to the Majeed score system at the final follow-up.

Inclusion Criteria:

• 18-65 years, with normal activity ability before injury
