Abstract
Background: Despite extensive clinical experience with surgical management of cervical myelopathy, the idea of motion preservation remains unclear. The authors sought to comprehensively review the laminoplasty and oblique corpectomy literature spanning from January 1, 2000, to December 31, 2016 while focusing effects of laminoplasty and oblique corpectomy techniques on neurological outcome, spinal deformity and cervical ROM.
AIM OF THE STUDY: is to provide an updated comprehensive review of literature about management of cervical spondylotic myelopathy using motion sparing techniques.
METHODS: The authors conducted a literature survey of the Medline database, in which the terms “laminoplasty,” “laminectomy,” “posterior cervical spine procedures” and “oblique corpectomy” were used as key words spanning from January 1, 2000, to December 31, 2016.
RESULTS: A total of 11 studies for laminplasty and 4 for oblique corpectomy met our inclusion criteria., These studies described a total of 439 laminplasty and 431 MOC patients at the period between 2000- 2016. The mean follow up period was 68.1 and 48.75 months for laminplasty and OCC respectively. The mean JOA score improved from from being 10.64 ± 2.97 preoperatively to 14.1±2.24 postoperatively for laminplasty and from 10.4±3.03 preoperatively to 14.85±2.76 postoperatively for OCC. Subaxial laminoplasty prevented postoperative kyphotic deformity with the mean C2-C7 angle decreased only from 15.48 ±12° preoperatively to 14.77± 11.57° postoperatively, for OCC the mean C2-C7 angle decreased from 10.33±9.8° to 8.5±8.03°. The mean ROM decreased by 32.724% after surgery for laminplasty and by 35.5% for OCC.
CONCLUSION
The idea of a motion-sparing technique is the largest benefit when comparing laminoplasty to a laminectomy,and OCC to the anterior transcorporeal approach. A thorough decompression of the spinal canal and mobility is preserved postoperatively close to that of a preoperative spine, reducing the risk for adjacent segment disease.
