Active clinical trials for "Rupture"

This prospective study is to compare the rehabilitation effect between the patients with achilles tendon rupture using traditional rehabilitation protocol and acupuncture-assisted rehabilitation protocol. The main question it aims to answer is whether acupuncture is an effective rehabilitation treatment. The patients are divided into the traditional rehabilitation group and acupuncture assisted rehabilitation group. The time of return to light sports activity and other indicators of the two groups will be compared.

The goal of this observational clinical trial is to determine whether the posterior superior iliac spine of the hip or the humerus of the arm will produce larger amounts of bone marrow when harvested during surgery. Also, the secondary goal of this study is to determine the effects of the patient's position on the quantity of cells harvested from the hip, namely lying on back (prone) vs. lying on side (lateral decubitus). The main questions it aims to answer are: Will the hip or the arm have more bone marrow extracted? Does a patient lying in lateral decubitus position produce more bone marrow than lying in the prone position? Participants that are to undergo rotator-cuff repair are eligible for this study. During the participant's repair, bone marrow will be extracted from the arm and from the hip. Half of the eligible participants will have bone marrow extracted from the hip while lying on their side, while the other half will have bone marrow extracted from the hip while lying on their back. Researchers will compare the results from both extraction sites on each patient, as well as compare results of the two patient position groups.

The aim of this study is to investigate how hormonal contraceptives affect ACL rupture incidence within menstrual cycle phases. It is thought hormones such as estrogen and progesterone (which fluctuate throughout the normal menstrual cycle) play a role in the laxity of ligaments within the body. It is hypothesised that around the time of ovulation the ACL undergoes increased laxity, leaving it more likely to be injured. This study will look at the phase of the menstrual cycle in which the ACL injuries occur and whether there are differences due to the use and type of hormonal contraception participants may be using (such as Combined oral contraceptive, Mirena, Implanon), which can modify the levels of circulating estrogen and progesterone. This study involves participants completing an anonymous electronic survey after presenting to a sports or orthopaedic clinic with an ACL rupture. The survey collects information about participant's current ACL injury and any previous knee injuries; typical menstrual cycle patterns and the use of hormonal contraception; and history of sports participation. Responses will be analysed to look for similarities and differences in ACL injury occurrence by menstrual cycle phase and hormonal contraceptive use. The study hypotheses are: Hormonal contraceptives that are known to reduce ovulatory rises in estrogen will have the most consistent pattern of ACL rupture incidence across all phases of the menstrual cycle. There will be a mitigated risk of ACL rupture in the preovulatory phase of the menstrual cycle, relative to the other phases, in women using hormonal contraception compared to those not using hormonal contraception There will be a higher proportion of ACL ruptures during the preovulatory phase of the menstrual cycle in non-hormonal contraceptive users.

Over the course of a year from the start of the research study, twenty subjects will be randomized evenly into one of two groups after an informed consent is obtained: a traditional tight rope fixation group or a tight rope fixation with an anterior inferior tibiofibular ligament (AITFL) repair augmentation with an internal brace group. Subjects in both groups will acquire a bilateral WBCT pre-operatively and 6 weeks post-operatively at Atlantic Orthopaedic Specialists office. A within group statistical analyses will compare the volume of the syndesmosis acquired by the WBCT at 6 weeks.

This is a Post Market Clinical Follow Up Study in Orthopaedics, it will verify the long-term safety and performance of the device in the intended patient population, when indicated for the acute repair of the Achilles tendon. The Medical Device in this study AchilloCordPLUS is a Class IIb CE-Marked device manufactured by Xiros Ltd. AchilloCordPLUS is a single-use device, indicated for patients with acute Achilles tendon ruptures. It is particularly suited to active patients where an extended period of postoperative immobilisation is undesirable. This study is a prospective, multicentre, consecutively recruited non-randomised study. The total length of the study is expected to be 3 years. This includes a recruitment period of approximately 12 months and a 2-year follow-up. A total of 55 subjects will be enrolled into the study. Follow up is at 2,4,6,8 and 12 weeks, 6 months and 1 and 2 years. All subjects treated with the AchilloCordPLUS for acute Achilles tendon repair will be consecutively recruited into the study.

Increased knowledge is needed about new methods how to treat patients with Achilles tendon ruptures (ATR). A goal is to be able to individualize as well as improve treatment beyond the question about if surgery should be used or not. An overall aim of the project is to, in a randomized controlled trial (RCT), explore what impact a new treatment method with Neuromuscular Electrical Stimulation (NMES) - attached on the patients ́ calf muscles on the injured leg - in the early stages after an ATR, may have on tendon length, functional performance, biomechanical variables and patient reported outcome, both in the short and long term after the injury. 70 patients are planned to be included in this RCT and will be evaluated 3,6 and 12 months after their injury. Primary outcome will be heel-rise height. Secondary outcome will be tendon length, jumping ability, patient- reported outcome and biomechanical loading pattern. There is also a need to explore if the patients ́ loading patterns improve after treatment with NMES. Therefore, biomechanical variables in lower leg during walking and jumping will also be evaluated one year after their injury. The planned studies include completely new ways of exploring how to optimize the rehabilitation after an ATR. Since there might be an increased risk for overuse injuries in the healthy limb, there will also be focus on how the non- injured limb may be affected of an ATR. Taken together, this new knowledge can be helpful in the clinical setting to individualize and optimize patients' treatment and rehabilitation with the goal to guide the patient return to the same, or higher level of, physical activity as before the injury.

High-risk pregnancies often require long-term hospitalization or outpatient maternal and/or fetal monitoring, placing a burden on patients, hospital resources and society. The demand for intensified pregnancy surveillance and interventions is increasing, due to the increased prevalence of risk factors like obesity and advanced maternal age, as well as altered guidelines resulting in increasing labor induction rates.The main aims of the HOME study (Home monitoring of pregnancies at risk) are to assess if home monitoring of selected high-risk pregnancies for maternal and fetal wellbeing is feasible, safe (in a clinical trial), cost-efficient, and simultaneously empowers the users.

Protein convertase subtilisin/kexin type 9 (PCSK9) plays a regulatory role in cholesterol homeostasis by promoting low-density lipoprotein receptor (LDLr) degradation. Although the vast majority of the studies have focused on the role of PCSK9 in LDLr expression in the liver, an increasing body of evidence suggests that PCSK9 gene is also present in extra-hepatic tissues. A recent publication showed for the first time that PCSK9 is expressed in the ischemic heart and the expression is highest in the zone bordering the infarcted areas. Furthermore, the expression of PCSK9 is maximal early, at 1 week of ischemia. Mechanical complications (or cardiac ruptures) are uncommon but potentially lethal sequelae of acute myocardium infarction (AMI) and are commonly associated with early mortality without appropriate surgical intervention. It's unknown why some patients develop these devasting complications following AMI, while others not. Interestingly, studies have shown that post-infarction cardiac rupture affect the border zone between the ischemic and normal area and occur within the first 3 to 5 days after AMI. Based on the aforementioned observations, it's likely to assume a relationship between PCSK9 expression and the development of post-AMI cardiac rupture. Therefore, the main purpose of the this project is to study the PCSK9 gene polymorphism and its association with cardiac rupture. Investigators hypothesize that PCSK9 expression/secretion and development of post-AMI cardiac rupture may be a part of the dynamic changes at cellular levels occurring in the ischemic heart of genetically predisposed patients.

To find the preferred method of labor induction (birth augmentation) for women with a history of one prior cesarean section scar and in grandmultiparas, the difference in time interval from augmentation to delivery will be measured between breast stimulation vs. low-dose oxytocin administration in this prospective single-center randomized controlled trial.

Prelabour rupture of membranes (PROM) is associated with intrauterine infection and maternal and neonatal consequences. This risk increases with the length of time from PROM to delivery. Induction of labor has been shown to reduce the rates of those complications, however the optimal time interval has not yet been determined. The main purpose of this single-center randomized prospective study is to assess the differences between two approaches of managing PROM at term-expectant management and induction with a dinoprostone vaginal delivery system.
