Does the Relationship Between Bone Cement and the Intravertebral Cleft of Kummell Disease Affect the Efficacy of PKP?

Objective: To study the relationship between distribution of bone cement and intravertebral cleft of patients with Kummell disease on the clinical effect of percutaneous kyphoplasty (PKP).

Methods: According to the relationship between the distribution of bone cement and the cleft in the vertebrae, a total of 92 patients with Kummell disease who underwent PKP in our hospital were divided into 2 groups. Specifically, the bone cement of patients in group A was localized in the cleft of the vertebrae and did not infiltrate around the cleft, while that of group B patients not only filled the cleft of the vertebrae, but also distributed diffusely around the cleft of the vertebrae.
