Translaminar screw fixation of the lumbar spine.

Lower lumbar spinal fusion was carried out in 72 patients by a technique which involved screw fixation of the facet joints. Stability was achieved and mobilisation was allowed immediately. Radiographs after operation showed bony fusion in 94.5%. Pain was diminished and 76% of the patients would undergo the same treatment again. There were no neurological complications. The technique is useful and safe for the fusion of short segments of the lumbar spine.
