Chronic Exertional Compartment Syndrome (CECS) Treated With Abobotulinumtoxin A
Compartment Syndrome of LegChronic Exertional Compartment Syndrome (CECS) is a painful condition affecting runners and it is caused by a reversible increase in pressure within a closed compartment in the leg. Currently, to diagnose CECS, a large needle is placed into the muscle to measure pressure, which is invasive and painful. After diagnosis, the gold standard of treatment is surgery, which is also invasive, involves a prolonged return to play, and has a significant number of treatment failures. A growing literature has suggested alternative methods to both diagnosis and treatment that include the use of ultrasound to investigate muscle stiffness with shear wave elastography (SWE), and treatment with botulinum toxin injection into the muscle. The investigators propose a single-site randomized clinical trial to investigate the use of abobotulinumtoxinA in the treatment of CECS. Researchers also look to develop a non-invasive method for the diagnosis of CECS using SWE. To the researchers' knowledge, this is the first randomized study investigating the medication to treat this cause. The study will take place at Emory's outpatient sports medicine clinic. Potential participants will primarily be identified and recruited from the departments of Physical Medicine and Rehabilitation, Orthopedics, Physical Therapy, and Sports medicine as a part of regular clinical care. Participants will be included in the randomized portion of the study if they meet the previously established diagnostic criteria for CECS with compartmental pressure testing. This would be a landmark study to provide evidence for the use of an abobotulinumtoxinA in the treatment of CECS, leading to the potential avoidance of a surgical procedure. It could also change the means of diagnosis without the use of painful and invasive needle pressure testing that would provide patients and athletes with ease of care.

Long Term Outcomes of Pediatric Compartment Syndrome
Compartment SyndromesThe goal of this study is to review the etiology, diagnostic criteria, complications and outcome of acute pediatric compartment syndrome identified at The Children's Hospital of Western Ontario (CHWO) . Follow up with patients treated for compartment syndrome by fasciotomy will assist in determining the long term effects of compartment syndrome and surgical procedures on the patient quality of life and return to level of function of the affected limb.

The Research About Acute Compartment Syndrome
Acute Compartment SyndromeAcute compartment syndrome (ACS) is defined as a clinical entity originated from trauma or other conditions, and remains challenging to diagnose and treat effectively. Threre is the controversy in diagnosing, treating ACS. It was found that there was no criterion about the ACS, and result unnecessary osteotomy. The presence of clinical assessment (5P) always means the necrosis of muscles and was the most serious or irreversible stage of ACS. Besides pressure methods, the threshold of pressure identifying ACS was also controversial.

Biomarkers in the Diagnosis of Acute Compartment Syndrome
Acute Compartment SyndromeTibia FractureThis prospective multinational, multicentre cohort study aims to investigate the hypothesis that biomarkers of muscle cell damage can predict acute compartment syndrome in patients with tibial fractures.

Vasopressin in Intraabdominal Pressure Elevation
Intracranial Pressure IncreaseAbdominal Compartment SyndromeThe aim of this study is to investigate any direct correlation between increased intrathoracic pressure, intraabdominal pressure and intracranial pressure, following a controlled elevation in intraabdominal pressure and intrathoracic pressure (PEEP). The second end-point is to investigate any correlation between elevated intracranial pressure and vasopressin release, urine output and urine and serum osmolality by measuring their values at different time-points.

Evaluation of the Diagnostic and Therapeutic Value of Tissue Ultrafiltration in Patients at Risk...
Acute Compartment SyndromeThe study will enroll 200 adults ages 18-60 admitted to the hospital with severe open or closed fractures of the proximal tibia or tibial shaft at risk for ACS. Participants will be randomized to either treatment with tissue ultrafiltration (TUF) catheters (n=100) or to a control group (n=100). All patients will receive continuous pressure monitoring of the anterior compartment of their leg. Both groups will receive comprehensive clinical evaluation and will be treated according to the standard-of-care regarding management of their underlying injury and diagnosis of ACS as practiced by their treating surgeon. In addition, patients randomized to the experimental arm will have three TUF catheters placed in the anterior muscle compartment of the injured limb. The TUF catheters will be connected to a closed suction drain and will remove interstitial fluid from the muscle. All patients will be followed at 6 months following initial hospital discharge. This visit will include a clinical evaluation of complications, hospital admission and emergency room visits, wound and fracture healing, infection, muscle sensory and function exam and patient reported outcome

Botox for the Treatment of Recurrent Chronic Exertional Compartment Syndrome
Compartment Syndrome of Leg10 participants with Recurrent Chronic Exertional Compartment Syndrome (R-CECS) will be enrolled in a 6 month study at the University of Wisconsin Hospitals and Clinics to test the hypothesis that injection of Botox into the affected muscle group will alleviate pain associated with R-CECS.

Gene Expression in Lower Extremity Acute Traumatic Compartment Syndrome
Tibial Shaft FractureTibial Plateau FractureThe purpose of this study is to evaluate both genotypic differences and differences in local gene expression in individuals who develop acute traumatic compartment syndrome relative to control patients with at-risk lower extremity fractures who do not develop compartment syndrome.

Clinical Application and Validation of Innovative Tourniquet
Compartment Syndrome of ForearmBackground: Tourniquets are the basic equipment for nurses to perform blood draws, and venous indwelling needles for congestion, or for hemostasis. Therefore, forgetting to remove the tourniquet is a common problem that leads to blood circulation being blocked, and even severe tissue necrosis occurred. Purpose: The study aimed to evaluate whether this innovative tourniquet could prevent forgetting to remove the tourniquet, and improve the satisfaction of care. Research design: This clinical research trial was a quasi-experimental study designed for a single group with pre-and post-test. We will recruit 160 nurses in high-risk units of the hospital. The delay in removing the tourniquet as our study outcome is defined as the removing time delay of one minute. Expected results: The research results will provide some evidence of the efficacy of intelligent tourniquets.
