Adulkasem W The results of posterolateral spinal fusion by using autogenous iliac bone graft is gold stan-
dard. However, there are some undesirable effects at the donor site. This study reports the outcome
of posterolateral spinal fusion by using an autogenous bone graft from the lamina and spinous pro-
cess.
From June 1993 to May 2001, Decompressive laminectomy, pedicle screw fixation system
and posterolateral fusion were performed on 92 patients using autogenous bone from the decom-
pressive laminectomy procedure. The follow-up periods were 2-8 years. 97.56 per cent of the patients
had a solid fusion mass at 6 months after operation. There were no undesirable effects at the iliac
region. The JOA score for low back pain improved in all patients.
The result of posterolateral spinal fusion by using autogenous bone from the lamina and
spinous process is comparable to the autogenous iliac bone graft. The advantages of using the
laminospinous process bone graft are short operating time, less blood loss than taking a bone graft
from the iliac crest, no complication or undesirable effects at the iliac region.
