ABSTRACT
Objective:To explore the surgical techniques and clinical effects of minimally invasive adjustable plate (MIAP) together with distraction reduction by minimally invasive anterior pelvic ring internal fixator (INFIX) in the treatment of fresh Denis type ⅡB sacral fracture with sacral nerve injury.Methods:From June 2017 to June 2020, 12 fresh Denis type ⅡB sacral fractures were treated by anterior-posterior distraction reduction and fixation with MIAP and INFIX. There were 8 males and 4 females, with an average age of 30 years (from 16 to 44 years). Preoperatively, imaging found Denis ⅡB fracture of the sacrum and magnetic resonance neurography of the lumbosacral plexus showed injury to the sacral nerve root at the sacral foramen. All patients had symptoms of S 1 nerve root injury on the affected side after injury, with 9 cases of grade M0 and 3 cases of grade M1. The time from injury to operation averaged 11 days (from 5 to 19 days). INFIX combined with MIAP was used to distract and fixate the compressed sacral fracture. The quality of fracture reduction and recovery of sacral nerve function were evaluated postoperatively. Results:According to the criteria proposed by Lindahl et al., the quality of fracture reduction was excellent in 8 cases, good in 2 and fair in 2. The 12 cases were followed up for an average of 20 months (from 12 to 36 months). All sacral fractures got united after an average of 6 weeks (from 5 to 8 months). At one-year follow-up, according to the criteria proposed by the Nerve Injuries Committee of the British Medical Research Council, the postoperative muscle strength recovery was evaluated as complete recovery in 10 cases and as partial recovery in 2 cases.Conclusion:In the treatment of fresh Denis type ⅡB sacral fracture, MIAP combined with INFIX can obtain satisfactory clinical effects because the compressed sacrum can be effectively distracted, the sacral foramen be expanded and the sacral nerve be decompressed indirectly.
