Filter by:Displaced, multi-part intracapsular, proximal humerus fractures represent a major challenge for patients and orthopedic surgeons. Proximal humerus fractures represent the third most common fracture after hip and distal radius fractures, and more than 20% of these fractures meet operative indications. Unfortunately, one of the major complications of these fractures is the development of avascular necrosis (AVN), or death of the bone as a result of the loss of blood supply to it. Currently, the ability to predict AVN is limited. The purpose of this study is to determine if computed tomography imaging can identify a quantifiable predictor of AVN following this type of humeral fracture.
The study will evaluate the radiographs (x-rays) of 100 patients with a TriFIT total hip at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery to see if there has been any movement or wear in the hip stem over the course of the study. The study will also record clinical data on each patient using various functional tests and questionnaires at the same intervals.
This prospective, randomized, controlled, multi-center clinical trial will evaluate the effect and security of steroids therapy for patients of IgA nephropathy with active pathological changes,including crescents,necrosis and microthrombus.
The purpose of this study is the evaluation of the safety of autologous tissue-engineered dermal substitutes "denovoDerm" (first arm) and dermo-epidermal skin substitutes "denovoSkin" (second arm) transplanted onto the wound bed in children and adults.
This is a prospective, randomized, multicenter clinical study to compare the safety and efficacy of TC-A PS total knee system with TC-PLUS Solution PS total knee system in Chinese subjects.
Aseptic osteonecrosis of the hip (AOH) concern 1 Swiss young adult to 1000 (30-40 years old). They are responsible to a severe joint destruction and in the majority of cases a joint replacement. To the hip, we can distinguish 4 stages of osteonecrosis according to Ficat: 1, 2, 3, 4. Stage 3 and 4 AOH management are unanimous surgical. But management of stage 1 and 2 are unclear. Bisphophonates are mainly used for bone and osteoporosis diseases. They decrease the bone turn over, and the risk of fracture. They also decrease the bone marrow oedema and the pain associated to this oedema. Ibandronate is a bisphosphonate with a rapid effect, a short half-life, easy to manage, and with few side effects. We designed a double-blind prospective randomized trial aiming to evaluate the efficacy of an infusion of ibandronate versus placebo on pain and AOH progression in patients with stage 1 and 2 AOH. Our hypothesis is that there will be a pain reduction >=20 mm on the VAS scale (SD 10mm) in the ibandronate group versus placebo, and a non radiological progression in the treated group.
This study is intended to gather short (Pre-operative to 4-years) and mid-term (5-years) information regarding the performance and safety of the commercially available 36mm CERAMAX® Ceramic on Ceramic Total Hip System from a cohort of new study subjects that were not previously involved in the IDE study for this device.
This study is intended to gather medium (5- to 7-years) and long-term (minimum 8- to 10-years) information regarding the performance and safety of the commercially available 36mm CERAMAX® Ceramic on Ceramic (COC) Total Hip System from a cohort of study subjects that were previously enrolled in the IDE study. (COC = 36mm ceramic acetabular bearing insert component that articulates with a ceramic femoral head in the COC total hip replacement system)
This post-marketing study is designed to compare the safety of tofacitinib versus TNF inhibitor with respect to major cardiovascular adverse events and malignancies, excluding non-melanoma skin cancers when given to subjects with rheumatoid arthritis. Other safety events, including non-melanoma skin cancers, hepatic events, infections, and efficacy parameters will be collected and evaluated in the study.
