Front vs back surgery for a slipped lower-back vertebra
Part of Bones, joints & muscles, Pain clinical trials.
This trial compares two surgical approaches—operating from the front/side versus from the back—for a specific type of lower-back slip called lumbar isthmic spondylolisthesis. You may be eligible if you need surgery at a single level and have not had prior spine surgery, and if your back condition matches their exact limits.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 18 or older (or the age of majority in your province).
- You have a single-level lumbar isthmic spondylolisthesis and you need surgery for it.
- Your surgery plan must fit one group: either front/side (an anterior or oblique approach) or back-only (posterior approach).
- You can speak and understand English or French well enough for study visits.
- You have not had any previous spinal surgery.
- You do not have certain extra problems above or below the main level (like degenerative slipping or a pars defect) that would change the pattern.

This study compares two minimally invasive surgical methods for treating a type of lower back problem where one spinal bone slips forward over another. The goal is to see which approach gives better pain relief and function, helping you choose the best option.
This trial compares two approaches for chronic low back pain caused by worn discs: lumbar fusion surgery versus a structured multidisciplinary rehabilitation program. It aims to see which treatment provides better long-term relief and function.
This trial tests whether a spinal fusion surgery is better than staying with non-surgical treatments for people with long-term, severe low back pain from worn-out discs in the lower spine. It aims to find out which approach offers better pain relief and quality of life.
This study compares surgery and non-surgical care for an acute burst fracture in the middle-to-lower back. The goal is to see which approach works better for healing and recovery.
