Bones of the Arm of a Human Male as, Medial View

Description

Seen from the medial aspect, the upper limb skeleton runs from the scapula and glenohumeral region into the humerus, then distally through the elbow to the radius, ulna, and the bones of the hand. Proximally, the humeral shaft descends toward the medial epicondyle, which sits medial to the capitulum and aligns with the ulna at the humeroulnar joint. At the elbow, the ulna’s olecranon process projects posteriorly while the coronoid process lies anteriorly, bracketing the trochlear notch around the humeral trochlea; the radius remains lateral in anatomical position even though the view is medial, with its head and neck tucked against the ulna at the proximal radioulnar joint. Medial bony landmarks matter because they guide both diagnosis and approach at the elbow and forearm. Palpation of the medial epicondyle and the posterior edge of the olecranon helps frame assessment of elbow alignment after trauma, and these relationships are routinely referenced when judging supracondylar fractures or elbow dislocations on radiographs. The ulna’s subcutaneous posterior border and the prominence of the olecranon also explain why olecranon bursitis and triceps insertional avulsion are clinically conspicuous. Clear landmarks. Coursework in gross anatomy and kinesiology uses this perspective to teach humeroulnar hinge mechanics, the medial column of the elbow, and how the radius and ulna maintain their relative positions through pronation and supination. Orthopedic and sports medicine texts can pair the illustration with discussions of medial elbow pain, ulnar collateral ligament injury in throwers, and surgical exposure planning around the medial epicondyle and olecranon.
