Study Notes
Basic Upper Limb Anatomy
- The upper limb's main function is to position the hand.
- The shoulder girdle provides a wide range of motion.
- The elbow joint assists in shortening or lengthening the upper limb.
- The wrist stabilizes the hand.
Shoulder Joint Anatomy
- Review the anatomy of the shoulder joint.
- Learn the muscles acting on the shoulder and their movements.
- Study the brachial plexus and innervation of shoulder muscles.
- The main nerves of the shoulder and upper arm have important clinical relationships.
- Know the myotomes and dermatomes of the upper limb.
Interpreting Radiological Images of the Shoulder & Arm
- Bones, bony features, and joints must be identifiable on shoulder and arm radiographs.
- Recognize fractures and dislocations on radiographs.
Physical Examination of the Upper Limb
- Locate and identify bones and bony features of the shoulder and elbow joints.
- Locate superficial muscles, tendons, major vessels, and nerves.
- Learn how to test the shoulder's muscles.
Upper Limb Injuries and Clinical Reasoning
- Describe physical signs and complications from common injuries to the shoulder and upper arm.
