Arthrodesis, pre-sacral interbody technique, including disc space preparation, discectomy, with posterior instrumentation, with image guidance, includes bone graft when performed, L5-S1 interspace

The procedure described by CPT® Code 22586 refers to lumbar arthrodesis performed specifically at the L5-S1 interspace using a pre-sacral interbody technique. This technique involves several critical steps, including the preparation of the disc space, discectomy, and the placement of posterior instrumentation, all of which are conducted with the aid of image guidance. The term 'arthrodesis' denotes a surgical procedure aimed at fusing two or more vertebrae, thereby eliminating movement at the joint and providing stability to the spine. In this case, the pre-sacral interbody technique, also known as transsacral or paracoccygeal, is characterized by a minimally invasive approach that allows access to the anterior portion of the disc space through a small incision made near the coccyx. This method is particularly advantageous as it minimizes tissue disruption and can lead to quicker recovery times. The procedure includes the removal of the intervertebral disc material and the preparation of the end plates of the adjacent vertebrae, which is essential for successful fusion. Bone grafts, either from a donor (allografts) or the patient’s own body (autografts), are utilized to facilitate the fusion process. The final steps involve the implantation of posterior fixation devices, such as rods or screws, to ensure stability during the healing process. Overall, this procedure is designed to alleviate pain and restore function in patients suffering from conditions affecting the lumbar spine.
