The purpose of this study was to describe pressure originating in the six elbow articular compartments after muscular contractions. Ten cryopreserved cadaveric arms were dissected and the insertional tendons and capsuloligamentous tissues were preserved. The specimens were placed in a custom-made device. Elbow position was established at 90° flexion with the forearm in a neutral position and the wrist extended at 0°. Tekscan sensors sere used for measuring intraarticular pressures. Without loading the elbow, the humeroradial joint received the lowest pressure, and, among the humeroulnar joints, the highest pressure was found in the anterolateral compartment. After loading the epitrochlear muscles to the maximum (5.0 kg), the pressure increased in the anteromedial joint (0.6 kg to 3.3 kg) and decreased in the posteromedial and anterolateral joints (4.2 kg to 0.3 kg and 4.2 kg to 0.9 kg, respectively). After the same loading in the epicondylar muscles, the pressure increased in the anterolateral and humeroradial joints (4.2 kg to 8.2 kg and 0.2 kg to 1.0 kg respectively), but decreased in the posterolateral joint (3.4 kg to 1.0 kg). The pressure distribution patterns among the humeroulnar compartments depend on the muscle geometries and their origins. Understanding these patterns can be useful in applying physiotherapeutic treatments for reinforcement of different muscular groups in order to decrease pressure in certain articular compartments.
