Spine surgery showdown: cemented screws vs. standard screws for brittle bones
NCT ID NCT07294417
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at two surgical methods to fix the spine in people with osteoporosis (weak bones). It compares screws that are reinforced with bone cement to regular hollow screws. The goal is to see which method provides better stability, pain relief, and recovery, with fewer complications. About 70 adults with painful spine fractures or instability will take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥18 years old. * Both sexes. * Patients with confirmed osteoporosis on dual-energy X-ray absorptiometry (DEXA) scan (T-score ≤ -2.5), * Patients presented with painful osteoporotic vertebral fractures, degenerative instability, or traumatic compression fractures. * Patients are unresponsive to conservative management and require surgical stabilization.
