Background: Osteoporotic vertebral fractures and their complications pose increasing risks to the elderly. The purpose of this study was to evaluate the clinical efficacy of unilateral percutaneous vertebroplasty in patients with osteoporotic vertebral compression fractures (OVCF) by assessing postoperative cement distribution. Objective: This study aimed to investigate the impact of cement distribution on the efficacy of vertebral compression fracture repair to provide effective preventive and therapeutic measures, prevent postoperative vertebral re-fracture, and improve surgical outcomes. Methods: A total of 170 patients who underwent unilateral percutaneous vertebroplasty at our hospital from January 2020 to December 2022 were selected. Based on the postoperative X-ray cement distribution morphology, they were divided into the good distribution group (n = 87) and the poor dispersion group (n = 83). The basic information of patients, surgery-related indicators including operation time, total hospitalization costs, postoperative hospitalization time, cement injection volume, visual analog scale (VAS) for back pain, Oswestry Disability Index (ODI) for back pain, vertebral height restoration rate, local kyphotic angle of the vertebra, and incidence of re-fracture of injured and adjacent vertebrae were compared between the two groups, and the follow-up results of all patients were recorded. Results: There were no significant differences in age, gender, body mass index, fracture days, menopausal age of female patients, bone density T value, medical history, smoking history, alcohol history, and surgical segments between the two groups (P > 0.05). The VAS scores for back pain at 1 month and 1 year postoperatively were significantly lower in the good distribution group than in the poor dispersion group, with statistical significance (P < 0.05). The good distribution group had a significantly lower incidence of re-fracture of injured vertebrae and overall fracture incidence than the poor dispersion group (P < 0.05). There were no statistically significant differences in operation time, cement dosage, cement leakage, postoperative hospitalization time, adjacent vertebral fractures, postoperative vertebral height restoration rate, VAS scores for back pain at preoperative and 1 week postoperative, and ODI at preoperative, 1 week, 1 month, and 1 year postoperative between the two groups (P > 0.05). Conclusion: Compared with the poor dispersion group, patients in the cement distribution group achieved better short-term clinical efficacy, and long-term prognosis effects are still under observation. Moreover, the cement good distribution group significantly reduced the incidence of re-fracture of injured vertebrae and overall fracture incidence, thereby achieving better surgical outcomes.
