Introduction: We examined the utility of cement augmentation pedicle screws (CAPS) in lateral access corpectomy (LAC) for osteoporotic vertebral collapse (OVC).

Subjects and Methods: Twenty-five patients with OVC who underwent minimally invasive anterior and posterior reconstruction using LAC and percutaneous pedicle screw (PPS) fixation were included. All procedures were performed by the same surgeon at our institution. Patients who could be followed up for at least 2 years were included in this study. The mean patient age was 73.5 years, and mean follow-up period was 38.4 months. Patients were divided into two groups: those with CAPS (Group C) and those without CAPS (Group NC). We examined the number of fixed vertebrae, various parameters, Oswestry Disability Index (ODI), volume of cement injected, and complications.

Results: No significant differences were observed in patient demographics between the groups. However, the number of fixed vertebrae was significantly higher in the Group NC. Although spinopelvic parameters exhibited no significant differences, Group NC demonstrated a significant correction loss in local alignment. In both groups, ODI scores improved significantly after surgery. The average cement volume injected was 3.8 mL at the thoracolumbar junction and 5.4 mL in the middle and lower lumbar spine. No significant differences were observed in the bone fusion rates. However, screw loosening and cage subsidence were more frequent in the Group NC.

Conclusion: The use of CAPS combined with LAC reduced the fixation range without increasing complications.
