STUDY DESIGN: Radiologic evaluation utilizing computed tomography.
OBJECTIVES: To research the degenerative modifications of the side joints in sufferers with spondylolysis compared with management topics.
SUMMARY OF BACKGROUND DATA: Defects of the pars interarticularis are thought to lead to a discount of biomechanical stress on adjoining side joints. Subsequently, degenerative modifications of the side joints in sufferers with spondylolysis are anticipated to be lower than these in sufferers with out spondylolysis.
METHODS: Belly and pelvic multidetector computed tomography scans of 2000 topics, carried out for circumstances unrelated to low again ache, have been reviewed. A complete of 107 sufferers (37 girls and 70 males) with L5 spondylolysis have been recognized [spondylolysis (+) group]. Intercourse-matched and age-matched controls with out spondylolysis have been chosen randomly [spondylolysis (-) group]. Topics within the spondylolysis group have been subdivided into both bilateral spondylolysis or unilateral spondylolysis teams for comparability with the management group. 4 radiologic findings (narrowing, sclerosis, osteophyte, and bone cyst) indicative of degenerative change of the side joints adjoining to the L5 pars defects have been evaluated and the diploma of degenerative change was graded by summing the variety of degenerative modifications (rating vary, Zero-Four). The ? check and Mann-Whitney U check have been used for statistical evaluation.
RESULTS: Considerably extra degenerative modifications in each L4/L5 and L5/S side joints have been discovered within the spondylolysis (+) group than within the spondylolysis (-) group (? check, P <Zero.05). Degenerative modifications of the side joints at each L4/L5 and L5/S have been extra extreme within the bilateral spondylolysis (+) group than within the spondylolysis (-) group. Degenerative modifications of the side joints at each L4/L5 and L5/S have been extra extreme within the unilateral spondylolysis (+) group than within the spondylolysis (-) group.
CONCLUSIONS: Degenerative modifications of the side joints in sufferers with lumbar spondylolysis have been extra extreme than these with out spondylolysis.
