Although anterior and posterior decompression surgery are both reported to treat patients with myelopathy caused by ossification of the longitudinal ligament (OPLL). The surgical strategy disease is still controversial when OPLL multilevel severe. This present study reports preliminary clinical results a novel technique named controllable antidisplacement fusion (ACAF) for treatment multilevel-severe myelopathy. A series 15 cervical compression severe were enrolled. All underwent ACAF after thorough designing based on preoperative imaging. followed mean follow-up duration 9 months in this study. main procedures include discectomy involved levels, thinning part vertebrae, intervertebral cages, plate screws installation, bilateral osteotomies antedisplacement vertebrae-OPLL complex (VOC). Japanese Orthopaedic Association (JOA) scales, Visual Analog Scale (VAS) studied. And pre- postoperative radiological parameters, complications also investigated. Postoperative CT MRI showed complete cord VOC. Restoration neurological defects was confirmed at last assessment. Bone 6 follow-up. No specific identified that associated technique. demonstrates excellent outcome can be achieved use ACAF. Though further required confirm conclusion, has potential serve as an alternative OPLL.
