               Objectives To evaluate the feasibility, safety, clinical, and radiologic outcomes of a minimally
               invasive direct lateral-approach corpectomy (MIDLaC) for decompression and stabilization
               of symptomatic metastatic spinal cord compression (MSCC).
            
            
               Methods A retrospective study on a prospective cohort was conducted. Nineteen patients were
               consecutively treated with MIDLaC and posterior pedicle screw fixation between May
               2012 and July 2014. Demographic information and radiologic outcomes including sagittal
               deformity correction and vertebral body height were recorded. Operative variables
               (operative duration, blood loss) and clinical variables (Tokuhashi score, mortality,
               complication rate, pain visual analogue scale [VAS], opioid usage, and Frankel grade)
               were recorded and analyzed.
            
            
               Results All nineteen patients (mean age: 67.6 ± 12.7 years) successfully underwent MIDLaC
               with excellent neural decompression. Operative duration was 188.4 ± 30.3 minutes for
               single-level MIDLaC and 327.2 ± 71.9 minutes for multilevel surgery (p < 0.0001). Mean blood loss per spinal level was 390.8 mL with a decrease to 102.3
               mL excluding renal cell MSCC. A total of 47.4% of patients had a Tokuhashi score of
               0 to 8. There was one approach-related complication and one perioperative mortality.
               The overall complication rate was 15.8% (n = 3) with no postoperative wound infections. Kaplan-Meier survival estimates at 6
               months were 0.50. Overall, 31.6% of patients improved by one or more Frankel grades,
               and no patients demonstrated worsening neurology postoperatively. VAS was significantly
               improved postoperatively (p < 0.05). Vertebral body height was significantly increased (+7.6 ± 8.1 mm; p = 0.002), with improvements in lumbar lordosis (8.3 ± 7.3 degrees) and thoracic kyphosis
               (2.4 ± 7.1 degrees) postoperatively.
            
            
               Conclusion MIDLaC is a safe and feasible palliative approach in the management of MSCC with
               encouraging early clinical outcomes. Further prospective studies are required to define
               the role of MIDLaC in the management of MSCC vis-à-vis other mini-open or minimally
               invasive techniques.
