An osteotomy of the spine is a surgical procedure that involves the removal of a portion of a vertebra to correct spinal deformities, such as a flexion deformity. This procedure is performed through an anterior approach, which may involve incisions in the neck, thoracic region, thoracoabdominal area, abdomen, retropleural space, or retroperitoneal space, depending on the specific location and nature of the deformity. The goal of the osteotomy is to realign the affected vertebral segment, thereby improving the overall function and stability of the spine while alleviating associated pain. During the procedure, soft tissues surrounding the vertebra are carefully dissected to expose the vertebrae, and subperiosteal dissection is performed as necessary along the vertebral segment. Access to the intervertebral disc may require the removal of a portion of the lamina. A curette is then utilized to excise the intervertebral disc or any disc fragments. A wedge of bone is resected from the vertebral body, which may also involve the removal of adjacent ligaments and spinous processes. The surgeon applies manual pressure at the osteotomy site to facilitate the realignment of the vertebra while ensuring that nerve roots and other critical structures are protected and visualized throughout the procedure. Once the bony gap created by the wedge resection is closed, additional stabilization may be achieved through the use of bone grafts and/or spinal instrumentation. Post-operatively, a body cast or jacket may be applied to immobilize the spine as needed for optimal recovery.
