Anterior Decompression And Fusion

✓ Anterior decompression and fusion for treating ossification of the posterior longitudinal ligament of the cervical spine was performed in 12 patients. The central part of the vertebral body and the ossified area of the posterior longitudinal ligament were removed by means of a microrongeur and an air drill. The defect was filled with a long bone graft taken from the ilium. The operative results were excellent. Marked improvement of radicular and spinal cord signs was seen in all 12 cases. Three vertebral bodies were fused in one case, four in nine cases, and five in two cases. The highest level of fusion was C-2 and the lowest was T-1. It is considered that any ossification of the ligament below the C-2 level can be removed via an anterior approach as long as no more than five vertebral bodies are involved. Spinal computerized tomography was valuable in providing more detailed information about the stenotic spinal canal and the shape of the ossified ligament.

Surgical Decision Making

Abstract The anterior decompression technique, including vertebral body sliding osteotomy1 and anterior controllable antedisplacement fusion (ACAF),2 treats ossified posterior longitudinal ligament (OPLL) without actual excision of the OPLL.3 The fundamental strategy is to separate the mid-portion of the vertebral body along with the OPLL using bilateral anterior osteotomies followed by controllable antedisplacement. These techniques restore the space of the spinal canal anteriorly by anterior translation of the OPLL, avoiding excision and dural manipulation.4 We illustrate the case of a patient who had failed laminoplasty and the surgical decision making for ACAF. We discuss the other surgical options regarding patient selection, present preoperative and postoperative imaging, to demonstrate the efficacy of ACAF and show strategies of ACAF to make it a safe and effective procedure. We demonstrate our technique of ACAF using the intraoperative microscope and models in this video to illustrate the steps of ACAF. A written consent to the procedure was obtained from the patient.
