How does the doctor investigate for spondylolysis and spondylolisthesis?
Commonly, plain x-rays of the spine may be ordered with or without some basic blood investigations such as hemoglobin, erythrocyte sedimentation rate [ESR], CRP, RA test, serum calcium, phosphorus and alkaline phosphatase. Additionally, dynamic views may be asked for to document the presence of any abnormal mobility of the spine at the level of the spondylolysis or spondylolisthesis. These are views taken when you would be asked to bend forwards as much as possible and then, to bend backwards as much as possible. In cases of spondylolysis, oblique views may be asked for so as to better delineate the bony deficiencies.
