A New 3D Reconstruction Method To Assess Anatomical Restoration In Vertebral Compression Fractures.

Deformation of the spine following vertebral compression fracture (VCF) can be associated with severe spinal dysfunction. Anatomical restoration is described as the complete reduction and stable fixation of the fracture with the goal to restore the pre-fracture local and global spine properties. The essential need to obtain endplate reduction, and consider the whole vertebral body in the management of vertebral fractures is pointed out.

Osteointegration and Resorption of Intravertebral and Extravertebral Calcium Phosphate Cement.

Study Design: Eleven patients with painful osteoporotic vertebral fractures who underwent kyphoplasty using calcium phosphate (CaP) cement were followed up for 1 week, 1, 2, and 3 years in a monocentric, nonrandomized, noncontrolled retrospective trial.

Objective: This study investigates long-term radiomorphologic features of intraosseous CaP cement implants and of extraosseous CaP cement leakages for up to 3 years after implantation by kyphoplasty.

Summary Of Background Data: Kyphoplasty is frequently used for the treatment of painful osteoporotic fractures.

Minimum cement volume required in vertebral body augmentation--A biomechanical study comparing the permanent SpineJack device and balloon kyphoplasty in traumatic fracture.

Background: Minimally invasive treatment of vertebral fractures is basically characterized by cement augmentation. Using the combination of a permanent implant plus cement, it is now conceivable that the amount of cement can be reduced and so this augmentation could be an attractive opportunity for use in traumatic fractures in young and middle-aged patients. The objective of this study was to determine the smallest volume of cement necessary to stabilize fractured vertebrae comparing the SpineJack system to the gold standard, balloon kyphoplasty.

Strontium enhances osseointegration of calcium phosphate cement: a histomorphometric pilot study in ovariectomized rats.

Background: Calcium phosphate cements are used frequently in orthopedic and dental surgeries. Strontium-containing drugs serve as systemic osteoblast-activating medication in various clinical settings promoting mechanical stability of the osteoporotic bone.

Methods: Strontium-containing calcium phosphate cement (SPC) and calcium phosphate cement (CPC) were compared regarding their local and systemic effects on bone tissue in a standard animal model for osteoporotic bone.

Kyphoplasty in patients with multiple myeloma a retrospective comparative pilot study.

Background: This retrospective study of 73 myeloma patients with painful vertebral lesions compares clinical and radiomorphological outcomes up to 2 years after additional kyphoplasty, radiation therapy or systemic treatment only.

Methods: We assessed pain, disability and radiomorphological parameters by visual analogue scale (VAS 0-100), Oswestry Disability Index and by re-evaluating available follow-up X-rays, respectively, in patients that were treated according to a clinical pathway.

Results: After 2 years the VAS score was reduced in all groups by 66 ± 8.
