Expansive Cervical Laminoplasty by Anterior and Posterior Cervical Decompression in the Treatment of Cervical Spondylosis Myelopathy / 中国医师杂志

ABSTRACT

Objective To evaluate the clinical results of expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatment of Cervical Spondylosis Myelopathy with developmental cervical stenosis.Methods Retrospective analyze 32 patients of cervical spondylosis myelopathy treated with expansive cervical laminoplasty by anterior and posterior cervical decompression from Mar 1995 to Aug 2000 years, there were 21 males and 11 females, developmental cervical stenosis (DCS) with cervical intervertebral disc protrusion in 25 cases, with the ossification of cervical posterior longitudinal ligament (OPLL) in 7 cases. Neural functionality (JOA Scoring System), cervical axial symptoms, and pre-and post-surgery dynamic cervical spine lateral x-ray films and cervical vertebra MRI were evaluated. Results 32 cases had been followed up for an average of 24.3 months, with an average age 58.9 years (range 38-72). The average rate of improvement of the third and sixth in month postoperative,the first and third postoperative year was 58.1%,65.9%,69.1% and 68.4% respectively;the excellent and good was 71.9%,81.3%,78.1%,77.3% respectivery. Cervical axial symptoms were reduced. Instability of the cervical spine were not found and decompression was confirmed on MRI. Conclusion Expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatement of cervical spondylosis myelopathy with developmental cervical stenosis have good efficacy and it is a stable operative method.
