Some people have back problems caused by degenerative conditions or instability of the spine (eg. Spondylolisthesis). These problems can lead to pain, nerve issues, or difficulties in walking. A common treatment is a type of back surgery called lumbar interbody fusion, which helps stabilize the spine.
At the St. Maartenskliniek in the Netherlands, doctors have been using a special material called Fibergraft Bioactive Glass Putty for such surgeries since 2023. This material helps bones grow and heal, and it's placed inside the spine without needing extra bone from another part of the body.
This study will look at how well this material works by evaluating how many patients' bones successfully healed after surgery using this material. It will also look at how patients feel and recover after the procedure
