Clinical Studies

Anterior vs. Posterior Surgical Treatment for
Lumbar Isthmic Spondylolisthesis (iSpondy)

Paul Arnold, MD

Principal Investigator

This is a prospective, multi-center, observational, comparative, cohort study to compare anterior and posterior surgical approaches to treat isthmic spondylolisthesis. The study will enroll 156 patients and follow them for 24 months. The aim of this comparative effectiveness study is to compare outcomes of anterior and posterior surgical treatment for lumbar isthmic spondylolisthesis. The primary objective is to compare treatment effectiveness in terms of functional outcomes as measured by Oswestry Disability Index and to compare safety outcomes measured by surgery-related complications. Secondary objectives are to compare treatments in terms of differences in pain, quality of life, utility, need for re-operations and costs.
