Clinical Trial Summary

Compartment syndrome is a very serious musculoskeletal disorder, which can lead to potentially devastating consequences, such as limb amputation and life- threatening conditions. It is a well described medical condition considered to be an orthopaedic emergency affecting all ages. Even though compartment syndrome is a well described medical condition, the appropriate treatment (i.e., fasciotomy to release tissue pressure) is invasive and involves its own risks. Furthermore, and of most critical importance is the timing for the intervention of a fasciotomy. The concerned limb may already have had severe, sometimes even irreversible, tissue damage due to high intra- compartmental pressure within 6 to 10 hours. The standard diagnostic method for compartment syndrome is an invasive intra-compartmental pressure measurement via insertion of a pressure monitoring device into the muscle compartment. Commercially available intra compartmental pressure monitors have a highly variable intra-observer reproducibility and user errors are common. Compared to the invasive modalities, the Compremium Compartmental Compressibility Monitoring System (CPM#1) shows promising advantages for the clinical application. Not only is the technology used for the CPM#1 device safe and non-invasive for the patient with only initial training required for the healthcare professionals, but it has also demonstrated high intra- and inter- observer reproducibility (as per bench tests and clinical settings with prototypes, to be confirmed in clinical studies like this one). The use of the CPM#1 device therefore facilitates the measurements, as it is based on pre-existing ultrasound methods and avoids any further risks to the patients compared to invasive compartmental pressure diagnosis methods.

Outcome

Type Measure Description Time frame Safety issue
Other Assessment of adverse events and serious adverse events Safety of the procedure will be assessed by documenting adverse events and serious adverse events (description of the adverse events, number of participants). During the procedure which should last about 3 hours/patient
Other Assessment of device deficiencies Safety of the procedure will be assessed by documenting device deficiencies (description) During the procedure which should last about 3 hours/patient
Primary Inter-operator reproducibility with 3 raters Inter-operator reproducibility will be assessed using intra-class correlation coefficients (two-way random effects, single rater, absolute agreement). Three independent raters will conduct 4 measurements per compartment site on 14 relaxed forearms (7 volunteers, 1 site per forearm), and 14 relaxed legs (7 volunteers, 2 sites per leg). During the procedure which should last about 3 hours/patient
Secondary Intra-operator reproducibility Intra-operator reproducibility will be assessed using intra-class correlation coefficients (two-way mixed effects, single measurement, absolute agreement). Three independent raters will conduct 4 measurements per compartment site on 14 relaxed forearms (7 volunteers, 1 site per forearm), and 14 relaxed legs (7 volunteers, 2 sites per leg). During the procedure which should last about 3 hours/patient
Secondary Validation of number of measurement repetitions Clinically needed number of measurements for optimized repeatability will be assessed on 2, 3 and 4 measurement repetitions per compartment site based on 14 relaxed forearms (7 volunteers, 1 site per forearm), and 14 relaxed legs (7 volunteers, 2 sites per leg). During the procedure which should last about 3 hours/patient
