Active clinical trials for "Necrosis"

The aim of this study is to compare the effect of antimicrobial-corticosteroid mixture and cryotherapy as final root canal irrigating solutions on post-instrumentation pain in single-canal teeth with necrotic pulps.

This is a Post-Marketing Surveillance study of GMK Sphere cementless knee prosthesis.

The purpose of this post-market clinical follow up study is to assess the safety and effectiveness of the SYMBOL range of medical devices. The study will evaluate the outcome of Total Hip Arthroplasty using medical devices from SYMBOL range over a period of 10 years.

This registry aims to analyze long-term outcomes of therapeutic EUS (T-EUS) procedures, as well as to describe clinical and technical variables potentially predicting clinical success or adverse events, for a better selection of ideal candidates.

Although metal stents have been widely used in the endoscopic step-up approach for necrotizing pancreatitis, the exact timing of transmural stent removal has not been well studied. In this prospective, open-label, randomized controlled study, we recruited and enrolled consecutive patients with necrotizing pancreatitis undergoing endoscopic transmural necrosectomy. Eligible participants were randomly assigned to case group (a novel strategy in which the stents were removed during the last necrosectomy when the necrosectomy endpoint was achieved) and control group (the conventional strategy in which the stents were removed after the last necrosectomy when clinical symptoms were relieved and fluid was nearly completely resolved confirmed by imaging). The primary endpoint was the incidence of composite complications within three months of enrollment.

Avascular necrosis of the talus is a difficult problem to manage, especially in the young and healthy. The only option, historically, has been a talectomy and hindfoot fusion. While this is a viable option, it is not without its morbidity. Arthritis of surrounding joints is common, occurring anywhere from 1-10 years after the procedure. This is especially true in younger patients, where loss of motion can be life altering both physically and mentally. The search for alternatives has been limited. Recently, 3D printing has become more ubiquitous and affordable and newer medical alternatives have arisen thanks to this technology. The 3D custom talus is relatively new in the orthopaedic community, but has been used at several centers with good success. It has been shown to re-establish the normal alignment of the foot, preserve motion (with some achieving almost physiologic motion), and allow for almost normal ambulation. However, the data is still limited and further study is necessary. Our facility was recently approved to perform this procedure. Our hypothesis is that custom 3D printed talar body replacements, either used alone or with total ankle replacements, will maintain physiologic motion, have no difference in complications when compared to hindfoot fusions with allograft, lead to good outcome scores and patient satisfaction scores. Patients diagnosed with avascular necrosis of the talus who have already decided to undergo a procedure involving a 3D custom talus as part of their standard care (talar replacement, total ankle/total talus, etc) will be enrolled in the study. Patients will follow standard post-operative protocols and return to clinic at designated time periods (2 weeks, 6 weeks, 3 months, 6 months, 1 year). X-ray evaluation, Range of motion, return to ambulation, walking speed and patient reported outcomes will be evaluated at each visit. Data will then be compared with baseline measurements and use to determine the progression of patients over time after the procedure

Dental pulp necrosis is one of the most common pathological conditions that results in tooth loss. However, regeneration of functional dental pulp has proved difficult. Therefore, the investigators conduct a single-arm study to evaluate the efficacy and safety of pulp regeneration induced by SHED mixed with hyaluronic acid polymerization in patients with pulp necrosis of permanent teeth.

To measure the Effect of Rosmarinus Officinalis versus 2.5%Sodium Hypochlorite as Root canal Irrigants on the Intensity of post-operative pain and Bacterial Reduction in asymptomatic necrotic Mandibular premolars.

The study is a multicenter, retrospective and prospective, non-randomized, non-controlled and consecutive series post-market study. The purpose of this study is to collect long-term data confirming safety, performance and clinical benefits of the Anatomical Shoulder 2.0 Fracture System (Implants and Instrumentation) when used for fracture shoulder arthroplasty. The primary objective is the assessment of safety by analyzing implant survivorship. This will be established by recording the incidence and frequency of revisions, complications and adverse events. Relation of the events to implant, instrumentation and/or procedure should be specified. The secondary objective is the assessment of performance and clinical benefits by recording patient-reported clinical outcome measures (PROMs) as well as radiographic outcomes.

This study investigates fluorescence image-guided surgery to allow precise identification of necrotic tissue both preoperatively and intraoperatively in burn patients. Furthermore, it uses a multi-model approach to elucidate the localization of ICG in inflammation and necrosis to determine how this novel use of a well-known fluorescence marker can be optimized to aid in surgical decision making. This proposal will provide the necessary data to support the design of a larger clinical trial to study the feasibility and efficacy of this technology to improve the precision of necrosis detection and removal and improve wound healing outcomes. Up to 100 participants will be on study for up to approximately 24 days.
