A novel unilateral extrapedicular approach applied to percutaneous vertebral augmentation to treat thoracic and lumbar Osteoporotic Vertebral Compression Fracture: a retrospective study
Abstract
Abstract Objective To design and apply a novel puncture method, named P TO P technique, and to evaluate its efficacy and safety. Method The data of patients treated with PVA in medical institution from January 2020 to December 2022 were reviewed and analyzed. The degree of pain relief and recovery from daily activities were evaluated using VAS and LAS scores, and radiological parameters were evaluated using local kyphosis angle and excellent cement distribution. Complications such as cement leakage and recurrent vertebral fractures were also recorded. Results 157 patients with thoracolumbar OVCF were successfully treated with novel puncture techniques. All postoperative clinical and radiological parameters significantly decreased in all patients, except for an increase in local kyphosis angle at the last follow-up compared to postoperative. All other above indicators remained statistically significant at the last follow-up compared to postoperative improvement. Except for 2 patients with poor cement distribution, the remaining 155 patients successfully achieved satisfactory results in unilateral puncture and bilateral cement distribution, achieving an excellent rate of 98.73%. In addition, 18 cases (11.46%) of cement leakage occurred during the operation, fortunately none of them were uncomfortable. During the postoperative follow-up period, 4 cases (2.55%) of recurrent fractures occurred. No other serious complications such as neurologic or named vascular injuries occurred. Conclusion The application of P TO P technology in thoracolumbar OVCF patients is safe and effective. It can not only reduce pain and quickly recover daily activities, but also achieve the perfect effect of unilateral puncture and bilateral cement filling.
