Sucato MD MS Abstract Thoracoscopically assisted surgery is a new approach to access the anterior spine to perform biopsies anterior releases diskectomies and anterior instrumentation and fusion for idiopathic thoracic scoliosis. This approach compromises the chest wall less than an open thoracotomy does because it uses several small portal incisions. It has been suggested that this approach allows fusion of fewer motion segments and better correction of curvature than does posterior spinal fusion and instrumentation. The technique which is still evolving is technically demanding requiring advanced training and special instrumentation and anesthesia techniques. J Am Acad Orthop Surg 2003 11 221-227 Surgical treatment for idiopathic scoliosis has changed rapidly in the last 20 years. Posterior segmental spinal instrumentation was an advance over Harrington instrumentation because it improved correction in the sagittal and coronal 2 The single solid rod used with anterior surgery was an improvement over the Dwyer cable especially for thoracolumbar and lumbar curves because it allowed surgeons to use a rotational maneuver to correct both the sagittal and coronal 2 Recently the single solid rod placed through an open thoracotomy has been used to correct thoracic 4 Anterior correction of thoracic scoliosis offers the theoretic advantage of better coronal correction because it permits the surgeon to perform diskectomies provides improvement in the thoracic hypokyphosis seen in idiopathic scoliosis and saves motion segments. In a prospective study Betz et al4 demonstrated that anterior surgery improved sagittal plane alignment while saving an average of distal motion segments compared with posterior surgery. In the last decade indications have increased for endoscopic approaches to thoracic spine surgery. Endoscopy .
