Laminaplasty (Yabuki's method) for Cervical Spinal Disorders

Between 1992 and 1994, 24 patients with cervical spinal disorders were treated with posterior laminaplasty using an autogenous spinous process bone grafting technique. This simple and inexpensive technique was reported by Yabuki in 1984. Subjects included 18 males and 6 females with a mean age of 61.6 years (range: 31-78 years), mean follow-up was 11.4 months (range: 3-30 months). All patients obtained excellent results with enlargement of the laminae averaging 153% (range: 138%-174%).
