Filter by:Pseudarthrosis of the humerus is a serious complication of humerus fractures, of particular interest to subjects young working people with pseudoarthrogenic risk factors (tobacco++). It represents a real problem therapeutic given the long period of treatment, its disabling socio-professional repercussions and the cost which resulting. The aim of our work is to evaluate the anatomical and functional results of different surgical techniques. used.
The goal of this study is to evaluate the bone regeneration capacity of BM-MSC (Bone marrow mesenchymal stromal cells), in patients with nonunion. BM-MSC cultured are seeded on a collagen scaffold, included into autologous platelet-rich plasma (PRP) clot, and implanted in the nonunion bone defect.
TRUFFLE is a register of clinical patient data of failed bone healing and bone non-union after fracture. All patients suffering from a long bone delayed or non-union after fracture and undergoing revision surgery are registered with their clinical data, comorbidities, medication, soft tissue status, radiographic status, Non-Union Scoring System (NUSS) Score and are followed up until final bone healing or end of treatment. The register consists of more than 800 patients cases. The aim is to identify risk factors for healing of non-unions. Data analysis will compare those patients that undergo regular healing to those of insufficient healing.
A single arm, multi-country, multi-center study in pediatric patients, suffering from congenital pseudarthrosis of the tibia (CPT), treated during the primary surgical intervention with NVD-003, an autologous 3D scaffold free osteogenic graft.
The objective of this single site, randomized controlled trial is to assess and compare radiographic and clinical outcomes in patients who are to undergo lumbar interbody fusion procedures (TLIF), supplemented with pedicle screw instrumentation, using one of the following interventions: 1. Porous titanium cages 2. Non-porous titanium-coated poly-ether-ether-ketone (PEEK) cages.
This study is a multi-centre, prospective, clinical observational study to evaluate the CE-marked HBS 2 Resorb Mg screws under routine conditions. The device will be used according to its intended use. The data collected for this study does only include measurements which are standard of care.
In 12 patients with corticalization and hypertrophic pseudarthrosis were present after dynamization, the old nail was removed and nail exchange was performed with a longer and larger diameter nail to pass the region formed in the cortex approximately 2-3cm inferior from the old nail.
The hypothesis of our study is that SPECT/CT bone scan fixation quantified by SUVMAX on a CZT solid state camera preoperatively would identify good responders to lumbar arthrodesis surgery.
Abstract Background: Treatment of non-union remains challenging and often necessitates augmentation of the resulting defect with an autologous bone graft (ABG). ABG is limited in quantity and its harvesting incurs an additional surgical intervention leaving the risk for associated complications and morbidities. Therefore, artificial bone graft substitutes that might replace autologous bone are needed. S53P4-type bioactive glass (BaG) is a promising material which might be used as bone graft substitute due to its osteostimulative, conductive and antimicrobial properties. In this study, the investigators plan to examine the clinical effectiveness of BaG as a bone graft substitute in Masquelet therapy in comparison with present standard Masquelet therapy using an ABG with tricalciumphosphate to fill the bone defect. Methods/design: This randomized controlled, clinical non-inferiority trial will be carried out at the Department of Orthopedics and Traumatology at Heidelberg University. Patients who suffer from tibial or femoral non-unions with a segmental bone defect of 2-5 cm and who are receiving Masquelet treatment will be included in the study. The resulting bone defect will either be filled with autologous bone and tricalciumphosphate (control group, N = 25) or BaG (S53P4) (study group, N = 25). Subsequent to operative therapy, all patients will receive the same standardized follow-up procedures. The primary endpoint of the study is union achieved 1year after surgery. Discussion: The results from the current study will help evaluate the clinical effectiveness of this promising biomaterial in non-union therapy. In addition, this randomized trial will help to identify potential benefits and limitations regarding the use of BaG in Masquelet therapy. Data from the study will increase the knowledge about BaG as a bone graft substitute as well as identify patients possibly benefiting from Masquelet therapy using BaG and those who are more likely to fail, thereby improving the quality of non-union treatment.
This is a post-market clinical follow-up study that use questionnaires such as Visual Analog Scale (VAS), the Neck Disability Index (NDI), or the Oswestry Disability Index (ODI) to compare the clinical improvement effects before and after surgery.
