RESUMEN
[Objective] To investigate the effect of SKY expander vertebroplasty and KYPHON vertebroplasty for compression fracture of thoracic/lumbar vertebral body. [Methods] Twenty-one patients (group A) with compression fracture in 27 thoracic/lumbar vertebral bodies were enrolled to this study. Among them, 17 fractured vertebral bodies from 15 patients received SKY expander vertebroplasty and another 10 fractured vertebral bodies from 6 patients received KYPHON vertebroplasty. Thirty-three patients (group B) with compression fracture in 35 thoracic/lumbar vertebral bodies receiving conservative treatment during the same period served as the control. After treatment, the therapeutic effect and result of X-ray image were compared in the two groups. [Results] A follow-up ranging from 1 month to 11 months showed that pain in the loin and back, decrease of vertebral height, complications of leaking of bone cement, and bed sore (which occurred in group B) were not found in the patients receiving vertebroplasty. [Conclusion] SKY expander vertebroplasty and KYPHON vertebroplasty are effective and safe for compression fracture of thoracic/lumbar vertebral body, which can relieve the back and loin pain as soon as possible, reconstruct the vertebral body, decrease the occurrence of complications and promote the rehabilitation, and have a better effect than conservative treatment. For the two kinds of vertebroplasty, SKY expander vertebroplasty is economic and indicated for single vertebral fracture and old fracture, and KYPHON vertebroplasty is indicated for multiple vertebral fracture, severe fracture, and vertebral body fracture with end-plate broken.
