•Anteriorly shoulder joint protected by subscapularis. •Superiorly shoulder joint protected by supraspinatus. •Posteriorly shoulder joint protected by teres minor and infraspinatus. •Inferior aspect of shoulder joint completely unprotected.
The upper limb has a wide range of precise movements associated with it to allow us to effectively interact with our environment, the 6 main joints covered here (from proximal to distal) are the sternoclavicular, acromioclavicular, shoulder, elbow, radioulnar, and wrist joints.
Distal surfaces of the carpal bones articulate with the bases of the metacarpals. The important thumb joint is the articulation between the trapezium and the bease of the first metacarpal. The INTERMETACARPAL joints ar adjacent metacarpals articulating with each other’s bases.
Upper limb 1. Shoulder girdle: clavicle and scapula 2. Free upper extremity: humerus, ulna, radius, carpal bones, metacarpals, and phalanges.
Joints (A gap is presented between the articular surfaces.) •Compulsory components (articular surfaces, cartilage, capsule and ligaments) •Optional components (discs, menisci, articular lips, bursae, tendon sheaths and articular muscles)
Bone: Upper limb - 12 Sternoclavicular joint ant. & post. sternoclavicular lig.; costoclavicular lig. , interclavicular lig.
Humerus and ulna: landmarks and articulations. the humerus is a long bone, the largest in the upper limb. it articulates proximally with the scapula at the scapulohumeral (glenohumeral) joint. it articulates distally with the ulna at the elbow joint. the ulna and humerus articulate at the elbow joint.
