Clinical Investigation of Anterior Spinal Reconstruction with Kaneda Device for Thoracolumbar Spine

We experienced 31 cases of anterior spinal reconstructive surgery using the Kanede device in the past 10 years. The cases consisted of 14 compression fractures (12 progrssive vertebral body collapses), 11 burst fractures, 2 old thoracolumbar fractutre-dislocations, 2 metastatic spinal tumors, and 2 spondylitis. Clinical and radiological investigation were conducted on the operated cases.The results showed that; 1) Evaluating by Frankel's classification, 77.8% of the cases had obtained improvment rates over 1 step According to Denis' pain score, pain relief was seen in 96.8%. The improvment rates of ambulance and urinary dysfunctions were 87.5 and 54.5% respectively.2)Radiological solid fusion was achieved in 93.5 % and the mean correction ratio for Kyphosis was 62.4%.
