Arthrodesis, pre-sacral interbody technique, including disc space preparation, discectomy, with posterior instrumentation, with image guidance, includes bone graft, when performed, lumbar, L4-L5 interspace (List separately in addition to code for primary procedure)

Arthrodesis refers to the surgical procedure aimed at fusing a joint, resulting in artificial ossification. This specific technique, known as the pre-sacral interbody technique, is characterized by its minimally invasive approach, which utilizes fluoroscopy for real-time imaging during the procedure. The primary goal of this technique is to address various spinal conditions, particularly those that have not responded to conservative treatments. It is indicated for patients suffering from pseudoarthritis, a condition where a previous fusion has failed, spinal stenosis, spondylolisthesis (specifically Grade I), and degenerative disc disease, all of which must be substantiated through a thorough medical history and imaging studies such as x-rays. The procedure involves making a small incision, typically measuring between 15 to 20 mm, located laterally to the coccyx. This incision allows for the insertion of surgical instruments that facilitate the preparation of the disc space and the subsequent fusion process. The use of bone graft material, which may be sourced from the patient (autograft) or a donor (allograft), is integral to filling the disc space and promoting successful fusion. Overall, the pre-sacral interbody technique is a sophisticated surgical intervention designed to alleviate pain and restore function in patients with specific spinal disorders.
