Lumbar-sacurm-iliac screws fixtion on the treatment of complicated sacral fractures

Abstract

Objective To investigate the clinical efficacy of lumbar-sacurm-iliac screws fixation in the treatment of complicated sacral fractures. Methods From January 2012 to October 2012, 18 complicated sacrum fracture patients with unstable pelvic fractures and cauda equina dysfunctionwere retrospectively studied, which Gibbons score were all 4 points. Surgical treatment was performed by posterior lumbar-sacurm-iliac screw fixation combined with sacral decompression. The fixation stage can be extended to L4, S2 level by fracture. According to the patient's nerve injury and fracture displacement surgery sacral decompression and observation of nerve root injury. After full decompression, correct the vertical displacement and rotate the displacement, and then place the cross further fixed. The first 3 months after surgery, the patient reviewed once a month, 3 months after the patient review once every six months. Results 18 patients underwent surgery for 2-21 d after injury, with an average of 10.2 d. The operation time is 150-240 min, an average of 180 min. Intraoperative blood loss of 600-2 000ml, an average of 1 100ml. The time of follow-up was 13-34 months, with an average of 23.4 months. Gibbons score averaged 4 points from preoperative to 2.78 points, the difference was statistically significant. Preoperative patients with an average angle of 42.89, postoperative 21.94, the difference was statistically significant. Postoperative Majeed scores averaged 64.5 points. Excellent in 3 cases, good in 3 cases, can be 7 cases, poor in 5 cases, excellent rate was 33.33%. Preoperative visual analogue scale (VAS) score averaged from 8.78 points before surgery to 2.22 points, this difference was statistically significant. The results of Tometta and Matto method were excellent in 5 cases, 3 cases were good, 7 cases were available, 5 cases were poor, excellent and good rate was 44.44%. Conclusion Lumbar-sacurm-iliac screw fixation in the treatment of complex sacral fractures can achieve a good reduction of fracture and attain satisfied nerve decompression, and more conducive to patients faster and better recovery.
