Filter by:This is a multi-centered, prospective, randomized controlled trial comparing current standard of care for defect management to placement of antibiotic loaded Stimulan as a bone void filler in patients undergoing treatment of infected tibial defects or infected tibial nonunions.
Fracture healing is a complex physiological process caused by interaction of cellular elements, cytokines and signaling proteins, which results in the formation of new bone (Gerstenfeld et al., 2003). Depending on fracture site, complexity, co-morbidities and other factors, 10% of all fractures will eventually fail to unite. Non-union fractures are defined as fractures that are at least six to nine months old and in which there have been no signs of healing for the last three months. Various causes have been evoked for impaired healing in hypotrophic (atrophic and oligotrophic) non-unions, including poor fracture stabilization, local infection and failure of the osteoblastic cells to multiply. Currently the treatment of choice for non-unions, particularly atrophic non-unions, is bone autograft (or allograft), combined or not with intramedullary nailing, plating, and external fixation devices (Kanakaris et al., 2007). This procedure produces good results but requires an invasive surgery of several hours under general anesthesia and a few days of hospitalization. Because of this, major complications have been reported in up to 20-30% of patients (Pieske et al., 2009, Zimmerman et al., 2009). This Phase 2b/3 study aims at demonstrating the safety and efficacy of PREOB®, a proprietary population of autologous osteoblastic cells, in the treatment of hypotrophic non-union fractures of long bones. PREOB® will be compared to Bone Autograft in a non-inferiority design.
The purpose of this clinical registry is to capture data on an ongoing basis from a population of patients who will use Biomet's BHS, OrthoPak and SpinalPak devices.
The primary objective is to establish if the SternumFix System improves sternal closure. The study should test the hypothesis that in a high risk patient population with increased risk for the development of sternal wound complications SternumFix will reduce the incidence of sternal healing complications. The control group will be treated with wire cerclage, the standard method of sternal closure.
The purpose of this clinical outcomes collection study is to analyze the effect of the EBI OsteoGen™ Direct Current Stimulator upon surgical reconstruction of tibia nonunion (no visible progressive signs of healing) fracture in a prospective database.
The purpose of this study is to analyze the effect of PEMF in surgical reconstruction of 5th metatarsal non-union fractures.
The purpose of this multi-center study is to obtain clinical data to substantiate that Aastrom TRC autologous bone marrow cells will regenerate bone in patients with established (appendicular skeletal) non union fractures, when used with one of the commonly employed commercially available allograft chip matrices.
