OBJECTIVE: Pedicle screw loosening and fractures of instrumented vertebrae are not uncommon and require reoperations, which are an immense burden on the patient and health care system. We aimed to describe a novel, simple percutaneous technique on instrumented vertebrae for treating pedicle screw loosening and demonstrate that corpus with osteoporotic vertebral compression fractures can be managed with this simple technique.-METHODS: This retrospective study was performed us-ing data gathered from 15 patients who underwent trans-foraminal vertebroplasty due to symptomatic pedicle screw loosening and vertebral body fracture between 2020 and 2021. Patients' symptoms, radiologic findings, intra-operative findings, and clinical outcomes were noted.-RESULTS: This series consisted of 5 male and 10 female patients, and the mean duration of follow-up was 8 months (range: 3 to 13). The average age was 66.67 +/- 4.59 years (range: 55L72). Preoperatively, symptoms were leg pain, -umbness of the lower extremity, and back pain. Post-operatively, no major complications were observed. Clin-ical progression of pedicle screw loosening and osteoporotic vertebral compression fractures were halted in all patients. None of the patients had permanent neurologic deficits. All the patients reported a dramatic decrease in pain immediately after the procedure. The vertebral fracture was detected in 3 patients, and screw loosening occurred in 12 patients. All symptoms resolved during follow-up.-CONCLUSIONS: Our preliminary results imply that transforaminal vertebroplasty is a safe and easy percuta-neous technique in symptomatic pedicle screw loosening and osteoporotic vertebral compression fractures in the instrumented vertebrae. Further trials on larger series are necessary to validate our data. |
