Arthrodesis, anterior interbody technique, including minimal discectomy to prepare interspace (other than for decompression); thoracic

Arthrodesis, specifically the anterior interbody technique, is a surgical procedure aimed at achieving spinal fusion by immobilizing a joint in the spine. This technique is particularly utilized for conditions such as herniated discs, lesions, and the stabilization of fractures and dislocations within the thoracic region of the spine. The procedure involves a minimal discectomy, which is the surgical removal of the intervertebral disc material to prepare the interspace for fusion, although it is not performed for decompression purposes. The approach is made from the neck, allowing the surgeon to access the thoracic vertebrae while carefully avoiding critical structures such as the esophagus, trachea, and thyroid gland. The procedure is characterized by the use of traction applied to the head, which helps in maintaining proper alignment and stability during the surgical intervention. The damaged vertebrae are meticulously prepared, and a bone graft is utilized to facilitate the fusion process, ensuring that the bones grow solidly together over time. This comprehensive approach not only addresses the immediate structural issues but also promotes long-term stability and healing of the spine.
