Joints of the Upper Limb

Overview

Joints of the upper limb provide a wide range of motion, allowing strength and precision in movement. This section introduces the articulations that connect the bones of the shoulder girdle, arm, forearm and hand.

Key Structures

Individual articles describe the structure, ligaments and movements of joints including the shoulder, elbow, radioulnar, wrist and interphalangeal joints. Functional overviews highlight how these articulations contribute to mobility and dexterity.

Clinical Relevance and Learning Focus

A clear understanding of joint anatomy supports the assessment of injury, degenerative disease and dislocation. Learners can apply this knowledge to clinical examination, imaging interpretation and orthopaedic management.
