COMPARATIVE STUDY OF EFFECTIVENESS IN LONG SEGMENT CERVICAL CORD DECOMPRESSION VIA ANTERIOR APPROACH VERSUS POSTERIOR APPROAC

A review of literature of the surgical options of spondylotic myelopathy disease included anatomy, biomechanics, physiology, pathology clinical picture, imaging and surgical procedures.The type of surgery depends on the site of compression and curvature of cervical spine.Anterior cervical discectomy and fusion is an excellent option for one or two level spondylosis without retro vertebral disease. Anterior corpectomy and strut grafting may provide an improved decompression, and is ideal for patients with kyphosis or neck pain. Laminectomy historically has poor results from late deformity and late neurologic deterioration, but has improved results with good surgical technique. Laminoplasty was developed to address cervical stenosis of three or more segments, and compares favorably with anterior corpectomy and fusion for neurologic recovery. Laminoplasty has a lower complication rate than corpectomy and strut grafting, but has a higher incidence of post-operative axial symptoms.
