Ronald Bartels' research activities are related to spine surgery, especially in relation to treatment of the metastatic involvement of the spine and of degenerative disorders of the spine.

The scientific interest followed the clinical one. Epidemiological training contributed to his interest in meta analytic studies and studies related to the efficacy of treatments.
