Abstract:

BACKGROUND: Percutaneous vertebroplasty and percutaneous kyphoplasty are effective minimally invasive treatments for type I or II Kummell disease, but it is still unclear which treatment is better.
OBJECTIVE: To compare the clinical efficacy of unipedicular percutaneous vertebroplasty and percutaneous kyphoplasty in the treatment of type I or II Kummell disease.
METHODS: Fifty-one patients with Kummell disease were admitted at the Department of Orthopedics, the Central Hospital of Yongzhou from January 2014 to September 2017, including 14 males and 37 females, aged 60-89 years old, responsible for T10-L3. Of which, 27 patients underwent unilateral puncture vertebroplasty with cement injection, and 24 patients underwent unilateral puncture kyphoplasty with cement injection. Intraoperative and postoperative cement leakage, transient fever and re-fracture were recorded. Before treatment, 1 day after treatment and at the last follow-up, the height of the vertebral body of the injured vertebrae and the Cobb angle were evaluated by imaging. Visual Analogue Scale and Oswestry dysfunction index were assessed before treatment and 1 day, 1, 6 and 12 months after treatment. The study was approved by the Ethics Committee of the Central Hospital of Yongzhou, Hunan Province.
RESULTS AND CONCLUSION: (1) There was no significant difference in the occurrence of cement leakage, transient fever and re-fracture between two groups (P > 0.05). (2) The height of the anterior edge of the injured vertebral body and the Cobb angle in the two groups were significantly improved after treatment (P < 0.05), and the improvement in the puncture kyphoplasty group was better than that in the puncture vertebroplasty group (P < 0.05). (3) The Visual Analogue Scale and Oswestry dysfunction index scores after treatment in the two groups were lower than those before treatment (P < 0.05). There was no significant difference in the scores between two groups (P > 0.05). (4) These results show that percutaneous kyphoplasty or percutaneous vertebroplasty can significantly alleviate the pain of patients with Kummell disease and obtain good effectiveness and safety. In contrast, percutaneous kyphoplasty can achieve better imaging height and Cobb angle reduction.
