There is a continuing search for novel synthetic materials as an alternative to autologous bone grafting. Different technologies are explored to promote bone formation, which include the addition of BioGlassTM particles in calcium phosphate (CaP) based materials and the use of surface modification in the form of submicron surface topographies. In this work we aimed at comparing the bone formation in a non-instrumented canine interspinous (IS) model of moldable formulations of a submicron surface structured tricalcium phosphate/alkylene oxide (CaP/AOC) or a tricalcium phosphate/BioGlassTM/collagen (CaP/BG/C) bone graft material...

BACKGROUND: Cell-based therapies are a promising treatment option for traumatic, tumorigenic and degenerative diseases of the spinal cord. Transplantation into the spinal cord is achieved with intravascular, intrathecal, or direct intraparenchymal injection. The current standard for direct injection is limited by surgical invasiveness, difficulty in reinjection, and the inability to directly target anatomical or pathological landmarks. The objective of this study was to present the proof of principle for minimally invasive, percutaneous transplantation of stem cells into the spinal cord parenchyma of live minipigs under MR guidance...

BACKGROUND CONTEXT: Spinal fusion procedures are intended to stabilize the spinal column for a multitude of disorders including abnormal curvature, traumatic instability, degenerative instability, and damage from infections or tumors. As an aid in the bone healing response, bone graft materials are utilized to bridge joints for arthrodesis and promote unions in pseudoarthrosis. Currently, the gold standard for stabilizing fusion masses in spinal procedures involves utilizing the osteogenic, osteoinductive, and osteoconductive properties of autologous iliac crest cortico-cancellous bone...

STUDY DESIGN: Biomechanical investigation. PURPOSE: Cervical two-level corpectomies with anterior-only instrumentation are associated with a high rate of implant-related complications. These procedures, therefore, often require an additional dorsal instrumentation to prevent screw loosening. Cement augmentation of the anterior screws in two-level corpectomies might stabilize the construct, so that a second dorsal procedure could be avoided. To evaluate the screw anchorage in cervical anterior-only procedures, an ex vivo evaluation of the range of motion (ROM) in two-level corpectomies (C4 and C5), with and without cement augmentation of the anterior screws, was carried out in this study...

The most commonly accepted indications for cervical disc arthroplasty (CDA) are 1- and 2-level cervical disc herniation or spondylosis causing radiculopathy or myelopathy that is refractory to medical management. Unlike anterior cervical discectomy and fusion (ACDF), which eliminates motion, CDA aims to restore the physiological range of motion of the indexed joint. Thus, the effect of indirect decompression gained by the insertion of a sufficiently large interbody graft and incorporation into arthrodesis after ACDF cannot be duplicated for CDA...
