Shoulder joint Shoulder joint The shoulder joint (or glenohumeral joint from Greek "glene", eyeball, + -"oid", 'form of', + Latin "humerus", shoulder) is structurally classified as a synovial ball and socket joint and functionally as a diarthrosis and multiaxial joint. It involves articulation between the glenoid cavity of the scapula (shoulder blade) and the head of the humerus (upper arm bone). Due to the very loose joint capsule that gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body. The shoulder joint is a ball and socket joint between the scapula and the
Supracondylar process of the humerus incidental finding on radiographs made for other reasons, but occasionally isolated fractures of the process itself may lead to its discovery. Rarely, presence of the process and a connecting ligament may lead to compression of the brachial artery and the median nerve, leading to pain, paresthesia and/or ischemia. The supracondylar process is a vestigial remnant of the supracondylar foramen or epitrochlear foramen found in other vertebrates including cats, climbing mammals and lower primates. Supracondylar process of the humerus The supracondylar process of the humerus (also known as an "avian spur") is a bony projection on the anteromedial aspect of the
