Comparison of therapeutic effect between percutaneous kyphoplasty and pedicle screw system on vertebral compression fracture

Objective: To compare the clinical efficacy of percutaneous kyphoplasty ( PKP) with pedicle screw system (PS) in the treatment of vertebral compression fracture (VCF). Methods: Eighty-six patients with VCF were treated either by PKP (Group A, n = 30)) or PS ( Group B, n = 56). The anterior, intermediate, and posterior heights of the vertebrae body , visual analogue pain scale( VAS) before and after operation, the duration of operation, and amount of blood loss between two groups were compared. Results: No statistical difference was noted regarding the vertebral height between two groups. Significant difference was seen in VAS, duration of operation and amount of blood loss between the two groups (P<0.0l ). Conclusions: Percutaneous kyphoplasty has the similar therapeutic efficacy with pedicle screw system in treatment of VCF with a minimal invasion, less operation time and blood loss. For those with posterior wall destruction, PS is deemed favorable.
