Active clinical trials for "Fractures, Bone"

Rotational deformity or malunion causes the most significant functional deficit in these common fractures. The evaluation of the rotation may be performed with the metacarpophalangeal joints flexed although postoperative swelling may not enable this examination with flexion of the fingers. Furthermore, it has been shown that swelling may cause rotation of the digit itself. The investigators propose that the swelling may cause a mistake in the estimation of rotation, during surgery and early follow up period. This is of special importance when open reduction and rigid fixation is performed. Methods: Prospective analysis of XX isolated metacarpal fractures treated, in YY patients was performed. End-on view of the finger-nail was taken with a digital camera on the day of OR, at 2 weeks and at 1 year. The photos were taken on a standard apparatus and from a distance of XX cm and evaluated using ZZ software in comparison with photos taken of the other hand, according to the involved digit. Range of motion, type of fracture and type of fixation were compared.

This is an observational pilot study of supernormal oxygen delivery goal for patients with proximal femoral fracture.

In Taiwan, about 75.92% of the elderlies above 65 years old suffered from chronic diseases or major diseases, especially in circulatory system. Thus, dramatic hemodynamic change is often observed in surgeries in this population. Due to osteoporosis and high-prevalence morbidities, trauma with fracture is quite common. These elderlies are more vulnerable to have complications, poor prognosis and decompensated organ functions. The investigators would like to observe the perfusion of different tissue intra-operatively, and to find the correlation with surgical outcome. There are many non-invasive hemodynamic monitors nowadays. In our study, the investigators will use noninvasive cardiac output measurement(NICOM), and non-invasive transcutaneous near infrared spectroscopy(NIRS) to observe hemodynamic change and tissue perfusion. After the surgery, the duration in ICU will be recorded. A questionnaire, SF-36, will be mailed to the patients 2 months after the surgery to measure the psychometric status.

In an attempt to answer if clavicular length changes after a fracture e.g. that any shortening becomes worse or better, 70 patients will be followed 3 times over 21 days using a novel ultrasound method.

Many patients with acute osteoporotic vertebral fracture (acute OVFs) admitted because of low back pain. But there are only part of patients with acute OVFs, because some patients do not have low back pain although OVFs occurred.

According to the patient's blood management concept, this study intends to collect basic information, surgical data, blood transfusion related data and patient prognosis data of patients with pelvic fractures, and to construct a predictive model of intraoperative blood transfusion in patients with pelvic fractures by multiple linear regression analysis. To guide physicians use blood accurately during surgery. Prompt doctors to reduce blood transfusion dose and improve patient prognosis by stopping bleeding and blood recovery before surgery.

Ankle fractures are among the most common osseous injuries to the lower extremity, and remain a significant source of morbidity for both the young and the elderly. Recent cross-national studies have shown a significant increase in the incidence and severity of ankle fractures among the elderly population.

A current problem in Radiology Departments is the constant increase in the number of studies performed. Currently the largest volume of studies belongs to plain x-rays. This problem is intensified by the shortage of specialists with dedication and experience in their interpretation. In the field of computer science, an area of study called Artificial Intelligence (AI) has emerged, which consists of a computer system that learns to perform specific routine tasks, and can complement or imitate human work. Since 2018, Hospital Italiano de Buenos Aires has been running the TRx program, which consists of the development of an AI-based tool to detect pathological findings in chest x-rays. The intended use of this tool is to assist non-imaging physicians in the diagnosis of chest x-rays by automatically detecting radiological findings. The present multicenter study seeks to externally validate the performance of an AI tool (TRx v1) as a diagnostic assistance tool for chest x-rays.

The bone fracture is usually diagnosed using an X-ray examination (the method of choice). However, in the case of the youngest patients (children and adolescents), it carries a potential risk of X-ray radiation exposure. What is important, an X-ray examination often fails to detect occult fractures or the early stages of a fracture with or without bone fusion. The literature emphasizes that from 2 to 36% of fractures may be unnoticed on X-ray images (false negative results). Therefore, additional possibilities are sought to improve the initial diagnosis. It was shown that ultrasound could be used instead of the conventional imaging. The most important advantages of the usg are the absence of radiation exposure and greater availability. Moreover, the evaluator is able to show neovascularization during usg examination, which is important in bone healing process. The aim of this study is (1) to validate the ultrasound imaging method for the fracture management; (2) to use an ultrasound imaging to assess the bone fracture and healing process during 8 weeks post injury. This study consists of 50 patients aged 10-18 years old. The forearm fracture will be diagnosed using an X-ray imaging as well as an ultrasound imaging in the first 3 days post injury (initial study). It is planned to assess the healing process after 2, 4, 6 and/or 8 weeks post injury (comparative study).

The aging of the population is a major public health problem, particularly with regard to the quality of life and the maintenance of autonomy. The fracture of the upper end of the femur (EFSF) is a pathology: Frequent, affecting the elderly: in France, 80,000 patients / year, 83% aged ≥ 75 years (DREES, 2011), severe, on mortality and autonomy: 40% will not recover their walking capacity earlier than 6 months, 13% of patients > 85 years old walk unaided at 4 months and 11% of patients will be newly admitted to an institution in 6 months after the fracture (UPOG / PSL data). and costly: costs related to acute care (excluding prostheses and osteosynthesis equipment), are estimated at € 475 million for health insurance in France. Currently, despite optimized orthogeriatric management, it is difficult to predict how the individual will respond / recover from acute stress related to the EFSF. Physical resilience is an emerging concept in medicine that defines the dynamic ability of a subject to resist or recover from functional decline as a result of stress or disruption. In this context, developing new approaches to assessing resilience is important, to take into account this resilience specific to each patient in order to develop a personalized functional rehabilitation strategy. The objective of the HIPRESM study is to be able to identify, in elderly patients after an EFSF intervention, the muscular signature associated with good functional recovery (= physical resilience). The goal of the investigators is to develop software that will provide this muscle signature by measuring and analyzing parameters from high-definition surface electromyography (HD-sEMG). This technology is innovative, non-invasive and portable, CE marked but not yet used in clinical routine.
