Posterolateral Lumbo-Scaral Fusion

Abstract

A consecutive series of 41 patients with unstable lumbo-sacral spine (spondylolysis, spondylolisthesis, disc lesion et al.) treated by a technique of posterolateral fusion resulted in a high percentage of good roentgenographic and clinical results.
Twenty-nine patients were male, and twelve were female (15-50 years).
The longest term follow-up was 3 years, and the shortest was ten months, the average being one year and six months.
Solid union occured in 90 per cent for fusion of single intervertebral joint roentgenographicly, but only 62 per cent for two or more levels.
However, a good clinical result was achieved in 83 per cent.
