This study evaluated whether or not the addition of gelatin micro-particles into the polymethyl methacrylate (PMMA) could reduce cement infiltration in cancellous bone of vertebra. ⋯ Gelatin micro-particles significantly increased the cement viscosity, reduced the permeability in cancellous bone of vertebra, decreased the flexural strength, but did not affect the compressive strength. Although it suggested a manageable approach in vertebral augmentation, the outcome should be further verified on a cadaveric model or an animal model before the mixture could be used safely and effectively in the clinical treatment.

Randomized Controlled Trial Comparative Study
Internal fixation with percutaneous kyphoplasty compared with simple percutaneous kyphoplasty for thoracolumbar burst fractures in elderly patients: a prospective randomized controlled trial.
The impact of percutaneous internal fixation as a supplement to percutaneous kyphoplasty (PKP) for the management of thoracolumbar burst fractures in elderly patients is unclear. We conducted a clinical controlled trial to investigate the effect and outcomes of this technique in such patients. ⋯ Compared with simple PKP, percutaneous internal fixation with PKP is a valuable surgical option for the treatment of selected elderly patients with thoracolumbar burst fractures.
