MY01 - An Aid for Diagnosing Acute Compartment Syndrome in Real Time

Study Overview
=================
Brief Summary
-----------------
Compartment syndrome can result from extremity trauma. It can also be caused by procedural cases that involve lower or upper extremity surgery. This condition results in muscle death, chronic pain, infection, and possible amputation. Early diagnosis is essential to institute interventions that can avoid complications. Subjective pain of the patient remains the mainstay for diagnosis. A method or device is needed that would improve our accuracy in diagnosing compartment syndrome. Ideally, this would be suited for single and/or continuous pressure read-outs. The aim is to reduce the incidence of missed compartment syndrome and diminish delays that would lead to significant disability. Despite awareness, delayed diagnosis and treatment occurs in modern orthopaedic practice. As noted in many studies, once a diagnosis has been made, immediate fasciotomy is necessary to provide the best chance for a favourable clinical result. Therefore, there is a need for improved devices in order to obtain an early and reliable diagnosis.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinical ease with which the new compartment pressure monitor was inserted into compartment. | At device insertion, the physician will complete a feedback questionnaire, and routine assessment will be performed in compliance with the standard of care. As part of the feedback questionnaire, the physician will be asked to indicate on a sliding scale How certain are you the device functioned adequately? [0 = not confident] - [10 = very confident]. The scale, administered part of a Clinical Report Form (CRF) titled 'Physician Survey', measures the physicians subjective level of certainty that the device sensor was inserted correctly within a patients muscle compartment. A record of 10 should be considered a very positive scenario, whereas a record of 0 should indicate a very negative scenario. | 24-48 hours following device insertion | 
| Ability to monitor in real-time the continuous pressure read-out from the compartment in remote locations such as an I-phone. | At device insertion, the physician will complete a feedback questionnaire, and routine assessment will be performed in compliance with the standard of care. As part of the feedback questionnaire, the physician will be asked to indicate in a Yes or No question Did the MY01 Application remote data display work properly? [Yes] or [No]. | 24-48 hours following device insertion | 
| The correlation of continuous pressure read-outs (high, normal or low) with clinical indications for compartment syndrome in each patient. | Routine assessments will be completed by healthcare personnel as per standard of care (the 6P's [Pain, Paraesthesia, Pallor, Paralysis, Pulselessness, Poikilothermia]), and compared against the pressure readout [mmHG] indicated by MY01's MicroElectroMechanical (MEMS) pressure sensor inserted at the afflicted location. | 24-48 hours following device insertion, and again during the final follow-up of the participant approximately two weeks after treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correlation of clinical compartment syndrome release with data from the continuous pressure monitor read-out. | Should surgical fasciotomy be deemed necessary to release pent up pressure in the patients muscle compartment, the continuous pressure read-outs [mmHG] derived from the device will be compared against the timeframe when the decision to conduct fasciotomy was made. | 24-48 hours following device insertion, and again during the final follow-up of the participant approximately two weeks after treatment | 
| Short-term outcomes of the patient following continuous pressure monitoring | Survey and tabulation of data from patient clinical findings. | 24-48 hours following device insertion. |
