About 200 cases of posterolateral lumbar-spine fusion were performed in our hospital from 1972 to 1979 in which 115 cases were examined during the period of more than three years.
Among these, 83 cases (112 intervertebral spaces) were followed up and compared with single and multiple posterolateral lumbar-spine fusion which were mainly assessed by roentogenographic and clinical results.
The incidence of solid fusion was high, 84.3% (intervertebral spaces, 88.4%).
For one level fusion the incidence was 94.6% and for multiple levels the incidence showed 63.0% (intervertebral spaces, 82.1%) solid fusions.
For disc lesions we had solid fusion in 93.3% (intervertebral spaces, 95.0%) but for spondylolysis and spondylolisthesis in 75.0% (intervertebral spaces, 81.0%).
In our cases there were no clear correlations between clinical and roentgenographic results.
It is suggested that cross unilateral lumbar-spine fusion is effective in the cases which need multiple spine fusions.
