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

Arthrodesis, specifically the anterior interbody technique, is a surgical procedure aimed at achieving spinal fusion by immobilizing a joint in the lumbar region of the spine. This technique involves the use of a minimal discectomy, which is the surgical removal of a portion of the intervertebral disc to prepare the interspace for fusion, although it is not performed for decompression purposes. The primary goal of this procedure is to induce the bones to grow solidly together, thereby stabilizing the spine. It is commonly indicated for conditions such as herniated discs, lesions, and stabilization of fractures or dislocations within the lumbar spine. The procedure is performed through an incision in the lower back, allowing access to the affected vertebrae. During the surgery, traction is applied to the patient's head to facilitate the alignment and stabilization of the spine. The damaged vertebrae are approached from the anterior aspect, and various instruments are utilized to prepare the intervertebral space for the placement of a bone graft, which is essential for the fusion process. This technique is critical in restoring spinal stability and alleviating pain associated with spinal disorders.
