The results of lumbosacral fusion for low back pain
FROM THE DEPARTMENT OF DIAGNOSTIC RADIOLOGY, UNIVERSITY HOSPITAL, LUND, THE DEPARTMENT OF ANATOMY, UNIVERSITY OF LUND, S-221 85 LUND, AND THE DEPART MENT OF ORTHOPAEDICS, ALLMANNA SJUKHUSET, S-21401 MALMO, SWEDEN. KINEMATIC ANALYSIS OF POSTEROLATERAL FUSION IN THE LUMBOSACRAL SPINE T. H. OLSSON, G. SELVIK and S. WILLNER In the past much effort has been devoted to the subject of spinal fusion and a great number of authors have reported various degrees of success (ROLANDER 1966). The various surgical techniques may partly explain the wide range of results, but the uncertainty of the methods previously used in determining the degree of spinal fusion obtained may also be a factor. This opinion is supported by ADKINS (1955) who states 'estimation of fusion by mobility radiographs is unreliable and cannot distinguish between fibrous ankylosis and bony fusion'. In experimental animals, the present authors (1975 a) showed that all movements between segments that have not fused with a complete bony union on both sides may be detected and quantified by a roentgen stereophotogrammetric method (SEL VIK 1974). Therefore the stability in the lumbosacral spine after posterolateral fusion was tested in three patients using this method. Case reports Case 1. Woman 46 years old,
