Surgical treatment of post-traumatic vertebral osteonecrosis including intravertebral expansive implants—clinical, functional and imaging outcomes and a center experience over 7 years

The effective treatment of post-traumatic vertebral osteonecrosis continues to be an under discussion and controversial subject. Armed kyphoplasty with expansive intravertebral implants is an emerging procedure, which, in theory, allow for a more effective preservation of the restored vertebral height. The development of the indications for these recent devices has given rise to auspicious outcomes in vertebral non-union situations. The aim of this study is to evaluate the clinical, functional and imaging outcomes of the surgical treatment of situations of post-traumatic vertebral necrosis, following a therapeutic algorithm that includes armed kyphoplasty with intravertebral expansive implants and bridge pedicular stabilization, according to a predefined necrosis stage.
