To assess with radiographic and clinical criteria the results of a new expandable mesh graft containment device for the treatment of stable spinal fractures.

Twenty consecutive patients with traumatic fractures of 26 thoracic (8) or lumbar (18) vertebrae (one in 14 patients and two in 6 patients) were treated after unsuccessful 6-week trial of conservative care using a new flexible mesh (OptiMesh system, Spineology, Inc. Stillwater, MN, USA) percutaneously deployed into the vertebral body through a small incision with parapedicular approach. Biologic granular bone graft materials were subsequently introduced and packed into the mesh which expanded after filling. Pre-treatment workup included history, physical exam and radiographic studies (X-ray and CT). After treatment, physical examination and X-ray of the affected vertebral tract (at the end of the procedure and at 12 weeks) and CT scan (at 12 weeks) were performed. In addition, pain and function scores were assessed pre-operatively, prior to discharge from our Hospital and at each follow-up visit using Visual Analog Scale (VAS) and Oswestry Disability Index questionnaire.

After treatment, X-ray and CT showed significant increase (p<0.001) of the anterior and central height of 25/26 (96.2%) treated vertebral bodies, with complete restoring of sagittal alignment and optimal bone fusion. At the first 24-hour follow-up visit, 18/20 (90%) patients reported a significant pain reduction which remained unchanged at the 12-week follow-up CT scan. 17/20 (85%) patients could quickly (within 2-4 weeks after treatment) return to their pre-injury normal level of activity.

The treatment of traumatic fractures of thoracolumbar vertebrae with the Optimesh system is safe and efficient. The osteoconductive and osteoinductive activity of this system provides structural stability by withstanding physiological loading and allowing for incorporation of the bone graft into native vertebral bone
