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