First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked back at 465 patients who had lumbar spine fusion surgery for degenerative disc disease. Researchers compared two types of implants (expandable cages and static cages) to see which ones were less likely to sink into the bone after surgery. The goal is to help surgeons choose the best device to reduce complications and improve patient outcomes.
