Abstract:
AIM: To evaluate acrylic resin bone cement in combination with percutaneous kyphoplasty to treat spinal metastatic tumor and reconstruct spinal stability. METHODS: Thirty-three cases with spinal metastatic tumor underwent percutaneous kyphoplasty in the Department of Spinal Surgery, Shenzhen People's Hospital between October 2006 and January 2008. All affected spines were complicated by destruction of bone or compression fracture. Under monitoring by G-arm X-ray machine, bilateral pedicle puncture was performed, followed by balloon expanding and acrylic resin bone cement injection in thoracic vertebra (3.6 mL) and lumbar vertebra (4.8 mL). All patients were followed up for 6 months to evaluate biocompatibility, vertebral height changes, pain degree pre-and post-surgery and movement ability. RESULTS: Of 49 affected vertebras in 33 cases, 43 were one-off successful, and 5 cases died of tumor metabasis. Finally, 43 vertebras were included in final analysis. The paired t-test showed the post-surgery anterior and posterior vertebral heights were significantly higher than pre-surgery [(2.6?0.6) cm, (2.2?0.6) cm; (2.9?0.7) cm, (2.6?0.6) cm; P
