    Study Notes

    Joint Anatomy

    • Articular structures: joint capsule, articular cartilage, synovium, synovial fluid, intra-articular ligaments, and juxta-articular bone
    • Articular cartilage: composed of collagen matrix, charged ions, and water, allowing it to change shape in response to pressure or load, acting as a cushion for underlying bone
    • Synovial fluid: provides nutrition to adjacent relatively avascular articular cartilage
    • Extra-articular structures: periarticular ligaments, tendons, bursae, muscle, fascia, bone, nerve, and overlying skin
    • Ligaments: rope-like bundles of collagen fibrils connecting bone to bone
    • Tendons: collagen fibers connecting muscle to bone
    • Bursae: pouches of synovial fluid that cushion the movement of tendons and muscles over bone or other joint structures

    Types of Joints

    • Not specified in the text, but there are different types of joints (e.g. synovial, cartilaginous, fibrous)

    Musculoskeletal Health History

    • Ask about pain: location, characteristics (using OLD CARTS), and mechanism of injury
    • Goal: determine if the pain is articular (joint) or extra-articular (outside joint), acute or chronic, inflammatory or non-inflammatory, and localized or diffuse

    Common Causes of Joint Pain by Age

    • Not specified in the text, but different age groups may have different common causes of joint pain

    Spine Pain Questions

    • Ask about location, radiation into shoulders/legs, arm or leg weakness, and bladder or bowel dysfunction
    • Red Flags for Low Back Pain: not specified in the text, but important to identify any signs of serious underlying conditions

    Techniques of Exam

    • Three broad sections: Look (visual), Feel (palpation), Move (evaluation of joint movement)
    • Inspect: look for deformity, asymmetry, swelling, scars, inflammation, or muscle atrophy
    • Palpate: feel surface landmarks, crepitus
    • Range of Motion: move actively by patient then by examiner
    • Special Maneuvers: if indicated

    Measuring Joint Range of Motion

    • Use a goniometer to measure joint range of motion
    • Helps determine how much range of motion is present or not present and can show improvement over time

    Joint Exams

    • Temporomandibular Joint Exam: not specified in the text
    • Shoulder Joint Exam: includes inspection, palpation, range of motion, and special maneuvers
    • Shoulder Joint Range of Motion: not specified in the text
    • Shoulder Special Tests: not specified in the text
    • Elbow Examination: not specified in the text
    • Wrist/Hand Examination: includes Finkelstein's Test, De Quervain Tenosynovitis, Carpal Tunnel Syndrome, Tinel and Phalen Signs, Allen Test, and Arterial Blood Supply to Hand

    Osteoarthritis vs Rheumatoid Arthritis

    • Not specified in the text, but important to differentiate between these two conditions

    Spine Examination

    • Neck Pain Assessment and Causes: not specified in the text
    • Low Back Pain Assessment and Causes: not specified in the text
    • Spine Special Tests: includes Spurling Test

    Health Promotion

    • USPSTF grade B recommendation on osteoporosis screening for women 65 and older or younger women with higher fracture risk
    • Osteoporosis: T score < -2.5, osteopenia: T score between -1 and -2.5
    • Risk factors for Osteoporosis: not specified in the text
    • Osteoporosis Screening: not specified in the text
    • Osteoporosis Prevention: not specified in the text
    • Calcium and Vitamin D Recommendations: not specified in the text
