Intracompartmental pressures (ICP) were continuously measured for up to 18 hours (as indicated by the FDA and Health Canada); clinical signs were simultaneously assessed for canonical compartment syndrome signs.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Outcome Measures and Comparisons:<\/jats:title>\n            <jats:p>The primary measurement outcomes were ease of use, accuracy, and safety of the device across all participating sites. Ease of use was assessed through surveys completed by surgeons, which evaluated their confidence in the device's functionality and usability. Accuracy was determined by analyzing patient outcomes, using surgical findings and clinical resolution as the gold standards, to assess whether the device's results corresponded to true positive and true negative cases of compartment syndrome. Feasibility was defined as the device's ability to integrate into the clinical workflow, operate reliably under typical conditions, and provide actionable data for ACS diagnosis. The secondary outcomes included continuous ICP measurements and their diagnostic value. Sensitivity and specificity were evaluated by comparing continuous ICP data with clinical assessments based on the \u201c6 P's\u201d (pain, pallor, paresthesia, pulselessness, poikilothermia, and paralysis) to determine their combined utility in diagnosing ACS.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>A total of 100 patients, 68 males and 32 females with an average age of 42 years old (17\u201380 years old), were enrolled. All of the patients had suffered a fracture, 25 proximal tibias (OTA\/AO-41), 40 midshaft tibias (OTA\/AO42), 13 distal tibias (OTA\/AO43), 11 forearms (OTA\/AO 2R.2U), 6 femurs (OTA\/AO31-33), and 5 humerus (OTA\/AO 11-13). Eighty-nine patients received the MEMS device postoperatively and 11 patients preoperatively. 93% of participating surgeons reported confidence in the device's function and ease of use. Pressures were measured on average for 16h 36 min (3 h\u201318 h). No complications were reported. Postoperative ICPs (25.4 mm Hg) were higher (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.0462) on average than preoperative ICPs (18.9 mm Hg). Patients who did not develop compartment syndrome had their postoperative pressures trend down after 4 hours (23.8 mm Hg). Sensitivity and specificity analyses of ICP alone, delta P alone, pressure trends alone, or a combination of the 3 metrics were conducted using patient outcomes as the gold standard for diagnostic accuracy. The trend of the curve in continuous monitoring pressure measurements proved more reliable than a single absolute pressure value in aiding in the correct diagnosis of ACS deviating from standard ACS diagnosis literature. The MEMS device allowed earlier diagnosis of ACS by 4 hours. When continuous pressure measurement was combined with standard clinical examination, the sensitivity and specificity reached 100%.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>The MEMS-based device reliably enabled continuous compartment pressure monitoring in all the study institutions. Further examination of continuous trends and accompanying perfusion pressure could allow surgeons the clinical adjunct to diagnose ACS many hours earlier than clinical signs alone.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>LEVEL OF EVIDENCE:<\/jats:title>\n            <jats:p>Therapeutic Level IV.
