Vertebral Body Osteopenia Associated With Posterolateral Spine Fusion in Humans

Abstract

Patients who have undergone instrumented posterolateral lumbar fusions have decreased vertebral body bone mineral density at the level of fusion compared with that of matched controls.

Degeneration of Sacroiliac Joint After Instrumented Lumbar or Lumbosacral Fusion

“…Furthermore, in the segments adjacent to the instrumented fusion, the bone mineral density was found to have decreased, 32,33 resulting in an adjacent vertebral fracture. Some studies 2,28 -33 suggested that accelerated degeneration of 1 or 2 segments adjacent to the fusion might occur because of the increased force transmitted to these joints.…”

Vertebral body compression fracture after removal of pedicle screws: a report of two cases

“…Of these possible complications, the most important concern is the stress-shielding effect of rigid implants. Previous studies have reported that vertebral body osteopenia may occur as a result of an instrumented spinal fusion [10,11]. Both of our cases involved patients who suffered from general osteoporosis, which obviously is unrelated to the implant.…”

Evolução psicossomática e clínica de pacientes com estenose do canal lombar operados com sistema interespinhoso

“…[28][29][30][31] The fact that we measured a dynamic stabilization technique made it essential to include only patients with moderate lumbar pathology, who had somehow retained the segmental mobility of their spine. We then selected Benzel lumbar degenerative bone pathology types 2 and 3, and Pfirmann degenerative disc disease types 3 and 4.…”
