Abstract
Modern concepts of treating thoracic diseases suggest more and more the use of minimally invasive thoracoscopic techniques to reduce morbidity and save costs. For treatment of specific lesions at the thoracic spine, several thoracoscopic procedures have been performed successfully. The present report examines the feasibility of thoracoscopic osteosynthesis in two patients with ventral hyperextension injuries and anterior instability of the thoracic spine. After initial correction of the anatomical deformity, autologous bone was harvested from the anterior iliac crest. Using a ventral, thoracoscopic approach, the main location of the ventral, damaged spinal segment was identified by the covering pleural haematoma. After endoscopic ventral bone grafting, osteosynthesis was performed, using dynamic compression plates, cardan drills and screw drivers. The perioperative course was uneventful, and follow up examinations after 3 years and 9 months, respectively, revealed an unchanged stable spinal segment. Our results show thoracoscopic osteosynthesis to be technically possible, with a potential for yielding satisfying long-term results.
