EnglishKyphoplasty and osteosynthesis is very safe in the treatment of vertebral body fractures. Our study analysed the results of 48 patients with acute vertebral body fractures of lumbar or thoracic spine classified as A3 according to Magerl et al. (1994) that were treated with percutaneous posterior transpedicular screw fixation combined with kyphoplasty between January 2012 and May 2015 retrospectively. 43 patients were operated at Magdeburg City Hospital and 5 patients at Bochum Bergmannsheil University Hospital (Germany). The radiological postoperative results showed good reduction of the vertebral body fracture after surgery and correction of the kyphotic angle measured with Cobb-technique. The loss of initially achieved correction was relatively small over a follow-up period of two years. The median Cobb-angle value increased to 5.35° after 6 months, 5.80° after 1 year and 6.0° after 2 years. The percentage of reduction was therefore reduced from 64.93% to 60.5% after 2 years. Patients with associated osteoporosis showed the highest values for loss of reduction indicating a possible relationship between osteoporosis and loss of correction. The combination of percutaneous osteosynthesis and kyphoplasty may be an efficient alternative to conventional open surgery, but a greater number of patients and longer follow-up time are required in order to make definitive statement possible.
