Clinical application of percutaneous kyphoplasty under the guidance of DynaCT in the treatment of compression fractures of thoracolumbar

OBJECTIVES: This study aims to investigate the clinical application values of percutaneous kyphoplasty (PKP) under the guidance of DynaCT in the treatment of compression fractures of thoracolumbar. METHODS: 57 patients with compression fractures of thoracolumbar who were treated with PKP in The Second People’s Hospital of Weifang from December 2014 to August 2016 were selected. Patients were randomly divided into DynaCT+DSA treatment group (27 cases) and DSA treatment group (30 cases) for PKP surgery. There were 19 cases of simple thoracic compression fractures, 28 cases of simple lumbar compression fractures, and 10 cases of thoracic vertebral compression fractures. Bone cement filling and leakage conditions were recorded after surgery. Efficacy of PKP was evaluated at 3 days after operation using visual analogue scale (VAS) and the maximal depth of the affected vertebrae. 71 lesioned vertebrae were treated and all punctures were successful. RESULTS: VAS score and height of the largest depression in vertebrae were significantly improved after surgery (p<0.05), while no significant differences were found between 2 groups. The leakage rate of bone cement in the two groups was 24.3% and 18.4%, respectively. CONCLUSION: DynaCT can be used to guide the development of vertebral puncture program before PKP, guide the accurate puncture during operation, and can be used to evaluate the leakage of bone cement timely and reliably.
