Tethers to prevent spine problems after deformity surgery
Part of Bones, joints & muscles clinical trials.
This trial tests whether special tethers (flexible support devices) placed during spine surgery can prevent a common problem called proximal junctional kyphosis—unwanted forward bending of the spine above where surgery was done. You would need to be planning major spine fusion surgery for spinal curvature.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older and need spine fusion surgery to correct spinal curvature
- Your surgery involves at least 4 spine levels and specific positioning (upper anchor between T9–L2, lower anchor between L5 and pelvis)
- You can sign consent and fill out questionnaires yourself
- You have health insurance (or are registered with French social security)
- You do not have a metal allergy, bone metabolism disorder, or BMI over 40
- You are not pregnant, do not have active infection or recent cancer, and can follow postoperative instructions

This trial tests whether wearing a back brace after surgery helps prevent problems at the top of a spinal fusion. It is for adults aged 30-75 having their first spine fusion from near the middle of the back down to the tailbone or pelvis.
This study looks at whether using a specific attachment system (VersaTie) with pedicle screws can help prevent problems near the top of a long spinal fusion. It compares outcomes in adults who are planning long posterior spine fusion surgery using this approach.
This trial studies a surgically placed “tether” system to help stop or slow worsening in certain types of scoliosis in growing teens. It’s for people whose curve is moderate-to-severe and who could not tolerate or didn’t respond to bracing.
This study looks at a surgical method (an “anterior vertebral body tether”) to help straighten the spine in growing children with certain types of scoliosis. It aims to see how well the tether system works over the next 2 years, compared with expected progress without the surgery.
This study follows kids who have a surgery called anterior vertebral body tethering (AVBT) for growing-related, idiopathic scoliosis. It looks at how well the curve stays corrected over time and how the spine grows, which may help improve future care decisions.
This trial studies how well specific lumbar (lower back) implant “cages” help fuse vertebrae in people with degenerative disc disease, spinal slippage, narrowing, curvature, or forward-bending deformity. It may help by testing an approach to improve stability and reduce symptoms after surgery.
