Objective: The intravertebral SpineJack® implant is developed for a specific purpose: for the anatomical restoration of vertebral compression fractures caused by an excessive craniocaudal unidirectional compression force. To reduce these VCFs, the SpineJack® initially deploys a controlled opposing craniocaudal unidirectional distraction force while preserving the surrounding bone trabeculae as much as possible. Once the fracture has been reduced, the SpineJack® maintains the restoration of the fracture before cement injection.

Methods: 29 patiens with osteoporotic vertebral compression fracture between T6 and L5 were been treated with the new implant and were been retrospectively examined. A visual analogue scale and radiological analysis (i.e., X-ray and CT scan) were used to assess back pain, quality of life and complications and height restoration of the vertebral body

Results: Significant reductions in anterior and central vertebral body heights were observed.

Conclusion: The obove mentioned technique provides a controlled craniocaudal expansion in vertebral compression fractures and maintains the restoration before the injection of cement and preserves bone trabeculae.
