15 Clinical Trials for Various Conditions
The purpose of the study is to investigate a relationship between the inflammatory response following intraarticular fracture and post-traumatic osteoarthritis. The investigators plan to evaluate the inflammatory cytokine profile in knee joint synovial fluid and blood serum in patients who sustain an intraarticular tibial plateau fracture and ankle joint synovial fluid and blood serum in patients who sustain an intraarticular tibial plafond fracture. This information will be combined with radiographs and patient outcome measures to determine a correlation between intraarticular inflammatory response and post-traumatic osteoarthritis.
The purpose of this study is to examine the effect of early, percutaneous, intra-articular saline lavage on the undiluted synovial fluid microenvironment during the acute phase following intra-articular fracture of the human ankle. We hypothesize that early intervention with percutaneous joint lavage in the first 0-48 hours after injury will attenuate the production of pro-inflammatory cytokines, MMP's and cartilage breakdown products compared to non-lavaged control subjects at the time of surgical fixation.
This study is a prospective, randomized controlled trial comparing the sinus tarsi approach to the extensile lateral approach for surgical fixation of calcaneus fractures. It is hypothesized that open reduction and internal fixation of intra-articular calcaneus fractures using a sinus tarsi approach will provide equivalent fracture reduction and stable fixation with significantly decreased wound complication rates in comparison to an extensile lateral approach.
The purpose of the study is to determine whether surgical hemostats can minimize blood loss, need for allogeneic blood transfusions and their associated risks, and costs in patients with certain acetabular fractures requiring operative fixation via a non-extensile Kocher-Langenbeck surgical approach. Since surgical hemostats and other topical agents like platelet gel products have also been linked with improved wound healing, incidence of wound dehiscence and/or infections will also be examined. The investigators primary hypothesis is the topical hemostat will result in lower blood losses intraoperatively and fewer units of perioperative blood product transfused.
Decreased range of motion is common after fractures around the knee and can impact a patient's ability to perform activities of daily living such as rising from a seated position or getting in and out of a bathtub. A continuous passive motion (CPM) machine is a machine that continuously moves a joint (such as the knee) without the patient having to use the muscles in his/her leg. A goal of this therapy is to maintain as much motion as possible following this injury. This study is a randomized, prospective study to evaluate the effectiveness of CPM in maintaining knee range of motion following open reduction and internal fixation (ORIF) of fractures around the knee
The objective of this study is to obtain and compare bilateral elbow joint synovial fluid from patients with unilateral intraarticular elbow fracture and a contralateral healthy appearing elbow joint. The synovial fluid samples will undergo several forms of analysis for metabolites and proteins. Matched-pair statistical analysis will be performed to determine the metabolites and proteins that may play the greatest role in development of joint contracture.
Comminuted intra-articular distal tibia fractures (OTA 43-C) typically are the result of high-energy trauma such as motor vehicle collisions or fall from a height. They are complex injuries often associated with significant fragment displacement and severe soft tissue injury, a combination that has long challenged orthopedic surgeons. Traditionally, surgeons use plain film (X-ray) and CT scans (2 or 3 dimensional) to determine fracture pattern and displacement. Yet, in some cases, it is still difficult to identify the relationship among bone fragments, which often makes articular restoration challenging. As a result, patients with non-anatomic joint reconstructions have a higher rate of poor outcomes. The primary objective of this study will be to compare patient outcomes in two groups, one group who will receive enhanced pre-operative planning (3D printed plastic prototype + standard of care \[SOC\] imaging with 3D CT scan + plain film radiographs) and a second group who will receive pre-operative planning using SOC imaging alone (3D CT scan + plain film radiographs only). Patient outcomes collected throughout the 12 month post-operative period will include an assessment of radiographic fracture healing (union, non-union, malunion), pain using a Numeric Pain Rating Scale, Olerud and Molander Score based on patient's self-report, and development of complications (infection, wound healing, re-operation, and re-hospitalizations). The secondary objective of this study will be to evaluate whether utilizing an enhanced pre-operative plan with a 3D printed plastic prototype altered the original pre-operative plan based on SOC imaging alone (3D CT scan + plain film radiographs only).
This is a prospective multi-site study. Subjects with distal radius fractures will be enrolled. Subjects will be treated surgically with a Sonoma WRx™ device or managed non-operatively with a splint or cast. Subjects will be enrolled in each group according to physician's standard of care (either casting/splinting or surgery) for distal radius fractures. Subjects will be enrolled based on the study's inclusion/exclusion criteria with a final qualifying decision made by a group of three independent adjudicators. The final qualifying review should allow for similar patient groups within each arm of the study due to the variability that can arise in fracture classification. Review by the adjudicators should be completed within 1 week.
High energy intra-articular fractures of the distal tibia, or Pilon fracture, is a devastating injury with multiple short and long term complications. The incidence of these injuries is increasing as survival rates after motor vehicle collisions increase. The current standard of care for high energy pilon fractures is to place an external fixator at the time of injury and then provide definitive internal fixation when the soft tissue envelope allows, which is usually around 10-14 days. Arguably, the most debilitating long term complication after a high energy pilon fracture is the development of post-traumatic osteoarthritis (PTOA), which occurs in 50% or more of pilon fractures within the first 2 years of surgery. The development of osteoarthritis occurs even in the presence of adequate restoration of the tibial plafond. Part of this issue lies in the fact that ankle joint cartilage is the thinnest of any major articular joint and sustains a great deal of damage at the time of injury. This impaction and injury initiates a cascade of events that ultimately result in cartilage cell death, or chondrolysis. Chondrolysis occurs via necrosis or apoptosis. Apoptosis occurs via a caspase pathway, while necrosis of chondrocytes likely occurs secondary to overproduction of reactive oxidant species (ROS). Recent animal models have demonstrated several things: chondrocyte death is highest along fracture lines, and likely undergo necrosis as opposed to apoptosis. The reason that PTOA likely occurs in such a high percentage of pilon fractures is because of this chondrolysis, and if a method can be developed to decrease the rate of chrondrocyte necrosis, then the rate of PTOA could potentially improve and improve patient outcomes overall. A recent bovine model examined the injection of N-acetylcysteine (NAC) after an intra-articular knee fracture and its effect on the cartilage cell viability. Their study demonstrated that chondrocyte cell viability after an injection of NAC within four hours of injury decreased chondrolysis from roughly 60% to about 30% at 48hrs. The effect was greater the closer to injury the injection occurred, and was statistically significant for 2 weeks. This indicates that free radical scavengers can potentially improve cartilage cell viability and help prevent the development of PTOA. No studies have been published on humans regarding injection of NAC after a fracture. However, a recent article examined the injection of NAC into osteoarthritic knees and found that it was effective in lowering certain cartilage degradation markers and was comparable to hyaluronic acid for both pain and function. NAC has been proven safe for both intra-articular injections and systemic injections in humans. Our study will focus on the improvement of cartilage cell viability with an injection of NAC. Our hypothesis is that the NAC intra-articular injection will increase the percentage of viable cartilage cell after sustaining a pilon fracture, when compared to a placebo injection of saline. The goal of this study is to examine the effects of an intra-articular injection of the amino acid NAC on cartilage cells after an intra-articular fracture of the ankle joint. The long-term clinical goal of this research is to reduce the incidence of post-traumatic osteoarthritis in the ankle joint after fracture.
High-energy tibial pilon fractures have historically been associated with poor outcomes largely due to the elevated risk of severe post-traumatic arthritis. Intraarticular fractures result in a pro-inflammatory hemarthrosis that may further exacerbate the chondral damage that was sustained due to the original injury. This project will study the effect of joint lavage on the concentration of inflammatory cytokines in the ankle following a high-energy tibial pilon fracture and the resultant effect on short-term patient outcomes.
The overall objective of this study is to compare outcomes following early advanced weight bearing (EAWB) using the AlterG antigravity treadmill versus standard of care physical therapy for adult patients with lower extremity periarticular injuries.
The primary objective of this study is to determine whether a patient with a tibial plateau fracture (non-displaced, displaced, or depression type) will have decreased pain and narcotic analgesia requirements following an intra-articular injection of local anesthetic and aspiration of the knee.
This study is a double-blinded placebo-controlled clinical trial evaluating the efficacy of 1 gram of topically applied tranexamic acid vs. saline placebo for the reduction of transfusion following hip hemiarthroplasty surgery.
The primary aim of the study is to see if a single wrist injection (intra-articular) of dexamethasone at the time of treatment will reduce the incidence of early-onset of post traumatic osteoarthritis.
The purpose of this study is to help determine if a static stretching brace in addition to physical therapy decreases the incidence of secondary operations, increases range of motion, and individual patient function.
