Illustrative case 2. A 51-year-old male patient suffered a L1 fracture during a motor vehicle accident (a, b). The AO Classification was 3.3.1, and the LSC was 9 (c, d). After primary closed reduction and posterior instrumentation at T12–L2 (e), staged anterior surgery using instrumented fusion was conducted after 6 days with partial corpectomy and implantation of a distractible vertebral body replacement. The preoperative RKA and TLA were 20.3° and 9.7°, respectively, and the RKA and TLA at the final follow-up of 33 months postoperatively were 1.4° and 2.2°, respectively (g, h). In the CT scan at the final follow-up, the anterior column was considered fused (f).
