BackgroundPercutaneous mesh-container-plasty (PMCP), a modified traditional percutaneous kyphoplasty (PKP) technique, is increasingly being used to treat osteoporotic vertebral compression fractures with up-endplate injury. This retrospective study aimed to compare the clinical and radiological results of PKP and PMCP for the treatment of this disease.MethodsWe retrospectively analyzed the medical records of patients with osteoporotic compression fractures and upper endplate injuries treated at our hospital between January 2019 and December 2021. A total of 192 patients who met the inclusion and exclusion criteria were enrolled. Of these, 103 underwent PKP and 89 underwent PMCP. Key outcome measures included surgical safety, clinical efficacy, and radiological results.ResultsBoth the PKP and PMCP groups showed significant improvements in visual analog scale and Oswestry Disability Index scores postoperatively. Additionally, anterior vertebral body height ratio and Cobb's angle improved in both groups, though no statistically significant difference was observed between them. The hospital stay duration was similar between the 2 cohorts. Notably, the PMCP group required a larger volume of bone cement injection yet exhibited a significantly lower incidence of cement leakage and adjacent vertebral fractures (9/89 and 2/89, respectively) compared to the PKP group (24/103 and 11/103, respectively) (P < 0.05). Moreover, the PMCP group had shorter operation times (34.64 ± 9.88 minutes) and reduced fluoroscopy frequency (35.43 ± 5.46 instances) compared to the PKP group (27.23 ± 8.54 minutes and 23.87 ± 5.59 instances, respectively) (P < 0.05).ConclusionsPMCP provided superior clinical outcomes for the management of osteoporotic compression fractures with upper endplate injuries. It was associated with reduced operation and fluoroscopy times, as well as lower risks of adjacent vertebral fractures and cement leakage, compared to PKP.Copyright © 2024 The Authors.
