Brief Summary: This study will test the safety of a new treatment method called tissue ultrafiltration We will test this method in the treatment of compartment syndrome a condition that occurs when pressure within the muscles builds to dangerous levels In the legs and other parts of the body a tough stiff membrane covers groups of muscles and the nerves and blood vessels that run next to and through them The entire unit is called a compartment The causes of compartment syndrome include traumatic leg injuries and loss of blood supply In tissue ultrafiltration a doctor places hollow probes or catheters directly into the muscle compartment in the injured area of the lower leg The probes remove fluid from the compartment extra fluid can cause increased pressure

We will do an initial safety study in a group of patients who have had surgery for a broken tibia the inner larger bone of the lower leg and are at high risk for developing compartment syndrome The goals of this initial study are to show that inserting tissue ultrafiltration catheters in the muscle compartment is safe and can be done repeatedly without problems to show that tissue ultrafiltration can be used to monitor the biochemical environment inside tissues and to show that the catheter apparatus provides an accurate measurement of pressure in the compartment
Detailed Description: The human clinical trials are organized as a series of consecutive studies designed to demonstrate the safety and efficacy of ultrafiltration in the management of compartment syndrome CS The first study is a cohort study of patients with tibial shaft fractures that will test the safety of the catheters as well as demonstrate that ultrafiltration fibers provide an improved method for monitoring myofascial compartment physiology The goals of this study are to 1 demonstrate that inserting ultrafiltration UF catheters is safe and reproducible 2 show that CSUF allows for biochemical assessment of cellular function and 3 show that the CSUF apparatus provides an accurate measurement of intracompartmental pressure

The study population will consist of 10 patients with closed or open Gustilo grade I grade II or grade IIIa tibial shaft fractures that require surgical stabilization We will recruit patients for the study at the study centers Data collected during this study will be numerical values for the biochemical measurements and for the intramuscular pressure IMP measurements We will compare the CSUF system values for intramuscular pressure with IMP measured with a Stryker device Finally we will correlate serial changes in the biochemical measures to any changes in IMP The metabolic assay will show increased UF levels compared to serum levels

We will consider fasciotomy when the IMP is within 30 mmHg of the patients diastolic blood pressure or when the clinical examination of the patient demands We will make repeat IMP measurements at the time of fasciotomy and record the interval to and reasons for fasciotomy

Following the operative stabilization of the tibial fracture and before the final closure of any traumatic wounds we will insert multiple UF catheters into the anterior lateral and posterior superficial and deep compartments of the leg Techniques used for catheter insertion will be similar to existing methods for the insertion of drainage catheters and we do not anticipate any specific difficulties with this step

To measure intramuscular pressure we will connect one of the catheters designed for this purpose to a standard pressure transducer and will use it to monitor intracompartmental pressure IMP in real-time In addition we will use a standard wick catheter inserted separately for control measurements

For biochemical measurements we will analyze samples of the interstitial fluid removed by CSUF for levels of creatine phosphokinase CPK lactic acid lactate dehydrogenase LDH osmolarity pH and pO2 We will obtain fluid every 4 hours for up to 48 hours The assays will be performed by standard clinical laboratory techniques
