title: Our technique of midsagittal splitting laminoplasty for compressive cervical myelopathy and its short-term results.
abstract: OBJECTIVE
  The aim of this study was to discuss the technique of midsagittal splitting laminoplasty and to compare its short-term follow-up results with laminectomy in cases of compressive cervical spinal cord myelopathy.
  
  
  METHODS
  Exclusion criteria were as follows: Intramedullary compressive lesions, kyphotic cervical spine, previous spinal surgeries, and defective anterior vertebral column. Twenty patients (10 each of laminoplasty and laminectomy groups) were prospectively studied from 2005 to 2008. After clinico-radiological assessment, laminoplasty or laminectomy was performed in patients aged <50 years and >50 years, respectively. The laminoplasty was performed by splitting the excised lamina in midline up to the tip of spinous process. Follow-up was done by neurosurgical cervical spine scoring, Nurick's grading, and the final outcome was determined by Odom's criteria.
  
  
  RESULTS
  The mean operative time and blood loss in laminoplasty and laminectomy was 100 ± 0.87 (range 90-140 min), 80 ± 0.67 (range 75-100 min) P = 0.04; and 65 ± 0.07 (range 60-90 ml) and 68 ± 0.61 (range 65-80 ml) P = 0.09, respectively. There were no intraoperative accidents, and no postoperative neurological deterioration/recurrence of symptoms. One patient who underwent laminectomy alone developed progressive kyphosis of the spine, whereas one having rheumatoid arthritis and long symptom duration didn't improve. 85% (17/20 patients) had sustained excellent to fair outcome (improvement by at least one Nurick's grade).
  
  
  CONCLUSIONS
  The technique used by us was simple, effective, and inexpensive. There was no minimal postoperative morbidity, although long-term results are awaited.
