Abstract:
Objective:To retrospectively compare the clinical efficacy of percutaneous vertebroplasty and biopsy by unilateral and bilateral pedicle approaches for the treatment of vertebral metastasis.Methods:From June 2020 to July 2022, a total of 82 patients with vertebral metastasis underwent percutaneous vertebroplasty and biopsy treated in Linyi Cancer Hospital were enrolled, 39 patients with 57 vertebral bodies were performed by unilateral pedicle approach (unilateral group) and 43 patients with 52 vertebral bodies were performed by bilateral pedicle approaches (bilateral group), used bone cement filling vertebral bodies after biopsy. The clinical efficacy and the positive rate of biopsy were compared between the two groups.Results:Both groups experienced significant pain relief in the Visual Analog Scale (VAS) score and improvement in the Oswestry Disability Index (ODI) score after operation ( P<0.05), but there were no significant differences between the two groups ( P>0.05). The operative time for a single vertebra, volume of bone cement in unilateral group were less than those in the bilateral group:(44.81 ± 13.01) min vs. (31.84 ± 11.87) min, (4.87 ± 0.92) ml vs. (4.18 ± 0.90) ml, there were significant differences ( P<0.05). There were no significant differences in the incidence of bone cement leakage and the positive rate of biopsy between both groups ( P>0.05). Conclusions:Percutaneous vertebroplasty and biopsy by unilateral and bilateral pedicle approaches are significant improvement for symptoms and functions of patients with vertebral metastasis. The clinical efficacy and the positive rate of biopsy are similar. But the former has easier operation procedure, shorter operative time and less volume of bone cement.
