Active clinical trials for "Fractures, Bone"

The purpose of this study is to compare percutaneous trans-iliac trans-sacral screw fixation to non-operative management for the treatment of symptomatic, sacral fragility fractures in elderly patients.

The purpose of this study is to examine the effect of variations in practice, ranging from early functional rehabilitation to complete immobilsation in post operative patients with ankle fixation following fractures. The primary goal of any post-operative regimen is to attain full weight-bearing and as close to pre-injury levels of activity as soon as possible. We seek to establish the effect on (1) functional outcome, (2) complication rates and (3) time to return to work of three different approaches to rehabilitation after ankle fracture fixation in order to produce a standardised, evidence-based guideline for our unit. We also aim to perform a cost analysis for each approach.

Patients will be randomized to volar plating with early ROM versus closed reduction with K-wires and 6 weeks of cast immobilization to determine if there is any advantage to volar plating in this subgroup of patients with distal radius fractures.

Certain types of fractures require surgical intervention that may involve the use of bone grafts or bone graft substitutes. Many of the materials used as bone graft substitutes suffer from disadvantages such as soft tissue invasion of the fracture area, inadequate blood supply, failure to encourage the production of bone and ectopic bone formation. A guided bone regeneration (GBR) environment may help in solving these clinical concerns. GBR has been widely used in the field of dentistry since the 1980s to provide stable placement for dental implants The purpose of this study is to evaluate the safety, performance and initial efficacy of Regenecure's, AMCA Bone Membrane, as a bone stimulating aid for orthopedic trauma applications.

The purpose of this study is to collect safety and performance data on the use of the Photodynamic Bone Stabilization System (PBSS) when used to provide stabilization and alignment for the treatment of acute humerus fractures.

Purpose: Hip fracture is a common disease on elderly. They become disabled easily if no adequate rehabilitation was given. The aim of the study is to compare the effectiveness of different types of post acute rehabilitation care for hip fracture.

Introduction: The orthopaedic surgeon is frequently exposed to ionizing radiation, especially during intraoperative fluoroscopy. It is expected that using a laser guided fluoroscopy technique, which should improve accuracy of radiography, should also reduce the amount of time of exposure to radiation. Finally, the literature appears controversial in this matter with no clear conclusions that could be drawn from such. Hypothesis: The test hypothesis is that the use of the laser-aiming device for fluoroscopy in several orthopaedic procedures will reduce the exposure of the patient and the surgeon to the damaging effects of radiation. The null hypothesis then states that there will be no difference in exposure to radiation between the group using the laser device and the group not using the apparatus. Methods: A prospective randomized controlled trial will be performed in which patients undergoing fluoroscopy will be randomly allocated to two groups. One group will undergo imaging with use of the device throughout the procedure and the other group will undergo radiation without the laser guided device. Number and time of exposure will be recorded for each procedure. It is of the utmost importance that the complexity of the procedures remains relatively similar. It is believed that a good measure of complexity is the surgical time. Therefore, any procedures that are statistically similar from a set mean (p > 0.05) would be included into the study. It is also important that one or two surgeons with similar expertise and years of experience perform the surgeries to avoid confounding factors. It is expected that throughout the duration of the study (8 weeks) 50-100 cases would be reported which would produce statistically significant results. The results will be analyzed by calculating confidence intervals and differences between means of continuous data and significance levels by the Student's t test. Statistical significance will be set to P < 0.05. Risks and Benefits: This study involves minimal risk. The use of the laser guide will not increase or introduce any risks other than the associated inherent surgical risks. The risks usually associated with this type of studies concern breach of confidentiality. To reduce this risk, research numbers will be assigned to subjects' data collected during the procedure, whose personal information will be found in another password-protected database. This study will help the investigators to investigate a technique that may help reduce the amount of time that a patient is exposed to radiation.

A randomised, prospective clinical investigation to compare post-operative fracture healing and complication rate after the fixation of ankle fractures using the Inion OTPS FreedomPlateTM Biodegradable Fixation System versus conventional stainless steel metal screws and plates. The objectives of the investigation are to compare post-operative fracture healing (union rates, time-to-union), and the complication rates (hardware failure, infection) between the two Plating Systems (biodegradable INION OTPS FreedomPlateTM vs. Stainless Steel 3.5 Reconstruction or DCP plate, or 1/3 Semitubular plates) at the clinical setting of Ankle fractures to study the safety of the clinical application of the biodegradable plating system of Inion OTPS FreedomPlateTM at the acute Ankle fracture setting.

Doctors are studying an investigational treatment to be used during the vertebroplasty procedure when treating vertebral compression fractures (spine fractures) that may help to reduce pain and restore mobility. If one has experienced back pain for at least 4 weeks but not longer than 1 year, he/she may be eligible to participate. The purpose of this protocol is to describe the methods for the clinical evaluation of Cortoss for vertebroplasty in patients with painful osteoporotic compression fractures. Eligible patients with painful osteoporotic compression fractures of the spine are divided into two groups. Each enrolled patient will have the vertebroplasty procedure; however one group of patients will have the vertebroplasty procedure using polymethylmethacrylate [PMMA] (a Food and Drug Administration [FDA]-approved bone cement) and the other group of patients will have the vertebroplasty procedure using a relatively new (investigational) biomaterial called Cortoss.

Fractures of the tibial shaft (diaphysis) are some of the most common long bone fractures. They most frequently occur in males less than 40 years of age. Despite advancements in the surgical management of these fractures, the precarious blood supply and lack of soft-tissue cover of the shaft of the tibia make these fractures vulnerable to non-union and infection. These complications often require multiple procedures, extended time off of work, and can result in ongoing poor mobility. This is reflected in the surgical revision rate that the scientific literature has recorded as being between 20 and 30%. Pulsed electromagnetic field (PEMF) stimulation has been shown to be a safe and effective treatment for non-unions of the tibia. These are fractures in which the bone has failed to unite and the healing process has ceased. The PEMF is delivered via a device such as the EBI Bone Healing System®, which straps onto the limb overlying the fracture. It is lightweight and portable using a rechargeable battery for power. It is compatible with internal and external fixation and may also be worn over a plaster or fibreglass cast. It is usually kept in place for ten hours per day and used for a period of three months or until the fracture unites. In animal models, PEMF stimulation has been demonstrated to improve the time to fracture healing in acute fractures. There have been no demonstrated side effects of the therapy. The study hypothesis is that PEMF stimulation during the first twelve weeks after fracture, in addition to normal surgical care, will increase the union rate for these fractures and thereby significantly reduce the surgical revision rate within the first twelve months following fracture.
