Efficacy of cement-augmented pedicle screw fixation for osteoporotic mid-thoracic vertebral fractures

BACKGROUND: Osteoporotic mid-thoracic vertebral fractures (OmTVF), often result in severe pain, and neurological deficits secondary to cord compression. Cement-augmented pedicle screw (CaPS) fixation with posterior spinal decompression (PSD) offers simultaneous decompression with stabilization of these osteoporotic vertebral fractures. METHODS: The study involved 32 patients (2022–2023) with T8–T10 osteoporotic vertebral compression fractures resulting in cord compression. All patients underwent CaPS surgery with PSD. Pain reduction was measured using the visual analog scale (VAS), and outcomes with the Oswestry Disability Index, and the American Spinal Injury Association Grades. The local kyphotic angle was also tracked with computed tomography studies performed 1, 3, and 6 months post-operatively. RESULTS: The average pre-operative VAS score was 8.56 mm; this decreased at 1, 3, and 6 months post-operatively to 2.72 mm, 2.03 mm, and 1.44 mm, respectively. In addition, 31 of 32 patients fully recovered within 6 postoperative months. CONCLUSION: For 31 of 32 patients with T8–T10 osteoporotic vertebral fractures, CaPS fixation with PSD successfully alleviated pain and resulted in significant post-operative neurological recovery.
