Brief Summary:
Compartment syndrome remains a very serious complication of lower extremity trauma and/or procedural cases that involved lower or upper extremity surgery. This condition results in muscle death, chronic pain, infection, and possible amputation. Early diagnosis is essential to institute interventions to avoid complications. Unfortunately, the subjective pain of the patient remains the mainstay for diagnosis. A method or device is needed that would improve the investigator's ability to diagnose this potentially devastating condition. The purpose of this trial is to evaluate the safety and functionality of MY01, an investigational device that allows continuous monitoring of intracompartmental muscle pressure in patients at risk for developing acute compartment syndrome. This is a single centre, non-randomized, non-controlled, unblinded, prospective trial of the MY01 device. A cohort of 25 participants will be prospectively enrolled to document the performance of the device.

Arm Intervention/treatment
Experimental: MY01 Device

Device: MY01 Device

Insertion of the MY01 device for up to 24 hours for continuous monitoring of compartment pressure

Device: MY01 Continuous Compartmental Pressure Monitor
The MY01 Continuous Compartmental Pressure Monitor is intended for real-time and continuous measurement of compartmental pressures.

Primary Outcome Measures :
  1. Clinical ease with which the MY01 device is able to be inserted into a compartment. [ Time Frame: 24-48 hours following device insertion. ]

    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 that the sensor is in the correction position?" [1 = uncertain] - [5 = very certain].

    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 5 should be considered a positive scenario, whereas a record of 1 should indicate a negative scenario.

  2. Ability to monitor in real time the continuous pressure readout from the compartment in remote locations via smartphone. [ Time Frame: 24-48 hours following device insertion. ]
    At insertion of device the physician will complete a feedback questionnaire on the device, the participant will be assessed for adverse events, and routine assessment will be performed.

  3. The change in intracompartmental pressure. [ Time Frame: 24-48 hours following device insertion. ]
    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.

Secondary Outcome Measures :
  1. Adverse events associated with the use of the device. [ Time Frame: 24-48 hours following device insertion, and again during the final follow-up of the participant approximately two weeks after treatment. ]
    The patient will be monitored for adverse events during treatment, and will be reassessed during the final follow-up of the participant at the first return visit to the fracture clinic. An adverse event constitutes "Any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal lab findings) in participants, users or other persons, whether or not related to the investigational device."

  2. Pain at insertion site. [ Time Frame: 24-48 hours following device insertion. ]
    Participants will be asked to keep a diary while the device is in situ. The diary will consist of a pain Visual Analog Score (VAS) to be completed each time their vitals are taken, with space to freely comment on the device. VAS will be on a sliding scale where [0=no pain] and [10=pain as bad as it can be].
