Elbow, Lateral View

Description

Seen in lateral profile, the distal humerus aligns with the proximal ulna and radius to define the cubital region, with the lateral epicondyle positioned anterior to the posteriorly projecting olecranon. The capitulum sits lateral to the trochlea, articulating with the radial head at the humeroradial joint, while the radial neck continues distally along the forearm axis. Posteriorly, the olecranon forms the palpable tip of the elbow, lying superior to the ulnar shaft and framing the posterior aspect of the humeroulnar articulation. Skin surface contours and overall posture of an adult Black female model provide realistic external landmarks for teaching palpation and joint orientation. Lateral elbow anatomy matters because many common injuries and pain generators localize to this side of the joint. The extensor tendon origin at the lateral epicondyle is the typical site of lateral epicondylitis (tennis elbow), and a true lateral view helps you relate symptoms to the bony origin, the radial head, and the annular ligament that stabilizes the proximal radioulnar joint. Lateral radiographs are also interpreted against this geometry when assessing radial head fractures and elbow dislocation alignment, including the relationship of the capitulum to the radial head. Small details. Big consequences. Use this figure in upper limb anatomy and kinesiology courses to correlate surface anatomy with the underlying articulation of the cubitus during flexion and extension, or in patient education materials explaining lateral elbow pain and imaging findings. It also fits orthopedic or sports medicine publications that need accurate depiction of the lateral elbow on a demographically representative adult female body.
