Manual Reduction for Subacute Osteoporotic Burst and Severe Compression Thoracolumbar Fractures

Abstract

The objective of this study was to retrospectively assess the impact of manual reduction (MR) on patients with subacute osteoporotic thoracolumbar burst fractures and severe compression fractures (OTLBFSCFs). From January 2016 to May 2020, 101 cases of OTLBFSCFs were reviewed, comprising 73 women and 28 men, with an average age of 77.4 ± 8.5 years. Preoperative radiographs, CT or MRI scans, intraoperative C-arm fluoroscopic images, and postoperative X-ray films were utilized to evaluate spinal radiographic parameters. Initially, all patients underwent 3 min of prone positioning as posture reduction (PR), followed by 1–3 sessions of six-member MR to approximate anatomical reduction of the fracture. The average preoperative anterior body height ratio (ABH%) and lateral Cobb angle (LCA) were 38.8% ± 6.2% and 22.6° ± 4.2°, respectively. Post-PR, the average ABH% and LCA were 50.5% ± 8.0% and 14.7° ± 2.7°, respectively. Following MR, the average ABH% and LCA were 99.6% ± 2.4% and 0.4° ± 2.4°, respectively. PR achieved an ABH% correction of 11.7%, while MR achieved 49.1%. LCA restoration was 7.9° with PR and 14.3° with MR. It was deduced that MR proved to be safe and efficacious for subacute OTLBFSCFs and could potentially alter the approach to subsequent surgeries.
