Anterior spinal fusion versus laminoplasty for cervical spondylotic myelopathy: a retrospective review.

Abstract:

PURPOSE:To compare outcomes of anterior spinal fusion (ASF) versus laminoplasty for cervical spondylotic myelopathy (CSM). METHODS:Records of 26 women and 37 men aged 34 to 83 (mean, 67) years who underwent ASF or laminoplasty for CSM were reviewed. Patient demographics, duration of symptoms, pre- and post-operative Japanese Orthopaedic Association (JOA) scores, Hirabayashi recovery rate, and radiographic features (including anteroposterior canal diameter, Pavlov ratio, and number of levels compressed) were compared. RESULTS:The mean duration of symptoms was 9 months. The mean follow-up period was 40 months. Patients who underwent laminoplasty were older (p=0.015) and had more levels compressed (p<0.001) than those who underwent ASF. Patients with C3/4 compression were older than those without it (p=0.044). Younger patients had higher Hirabayashi recovery rate (p=0.043). CONCLUSION:The surgical decision for ASF or laminoplasty mainly depends on the number of levels compressed and patient age. Laminoplasty is usually reserved for older patients with multiple level involvement. Age is the main predictive factor for surgical outcome.
