Bone morphogenetic protein-2 (BMP-2) is a potent osteoinductive cytokine that plays a critical role in bone regeneration and repair. However, its distribution and side effects are major barriers to its success as therapeutic treatment. The improvement of therapy using collagen delivery matrices has been reported. To investigate a delivery system on postero-lateral spinal fusion, both engineered...
BACKGROUND Extracorporeal shock wave treatment (ESWT) has been proven effective in enhancing spinal fusion in a preliminary animal study. However, biomechanical tests were not performed. METHODS All 12 rabbits in this study underwent decortication at the bilateral L5 and L6 transverse processes. Bone was chipped off and placed onto the intertransverse space. The rabbits were divided into two ...
Introduction: INTRODUCTION Posterior spinal fusion is a well-known, procedure in spinal surgery. The golden standard to achieve fusion remains autologous bone grafting. Although the exact mechanism of bone formation after grafting is unclear, there are some clues on the processes involved. New bone is originating and progressing from the decorticated processes by (a combination of ) osteoconduc...
BACKGROUND AND PURPOSE Injection therapies play a major role in the treatment of lower back pain and are to date performed mainly under CT or fluoroscopic guidance. The benefits of US-guided instillation procedures have been shown in many studies. We conducted this study to simplify an US-guided approach to the lumbar spinal nerves and to assess the feasibility and preliminary accuracy by means...
INTRODUCTION: Autologous bone is widely accepted as the gold standard for graft material because it generally offers the most predictable and favorable clinical outcomes. However, the procurement of autograft is associated with a high incidence of complications. In addition, the amount of autograft available can sometimes be limited (e.g., in long fusions and in patients undergoing multiple rev...
in this paper we investigate a new notion of bases in hilbert spaces and similarto fusion frame theory we introduce fusion bases theory in hilbert spaces. we also introducea new de nition of fusion dual sequence associated with a fusion basis and show that theoperators of a fusion dual sequence are continuous projections. next we de ne the fusionbiorthogonal sequence, bessel fusion basis, hilbe...
BACKGROUND Gene therapy has been utilized to achieve posterior intertransverse process fusion in rodents. To our knowledge, however, no one has previously reported on the use of this technique to achieve anterior spinal fusion in mammals. The purpose of the present study was to determine if a gene-therapy technique can be utilized to achieve anterior intradiscal fusion in pigs with use of minim...
