Hand Anatomy and Examination

Basics Description The hand is a unique organ that allows humans to work and to create. The hand can be conveniently divided into the palmar (volar) and dorsal parts. The volar portion of the hand contains the major digital nerves, the flexor tendons, and the muscles that allow finger movement. The bony architecture is […]

Elbow Anatomy and Examination

Basics Description Bones Ulnohumeral joint: The trochlea of the humerus articulates with the trochlear notch of the proximal ulna. The olecranon process of the ulna lies posterior to the joint. Allows for elbow flexion and extension Radiohumeral joint: The capitulum of the humerus articulates with the radial head. Allows for forearm supination and pronation […]
