  1. Health Sciences 1101Medical Terminology Module 10 The Musculoskeletal System

  2. Basic Musculoskeletal Terms Intro Video Orthopedics: The branch of medicine concerned with the prevention, diagnosis, care and treatment of disorders of the musculoskeletal system. Orthopedists or orthopedic surgeons: Physicians who specialize in orthopedics. Osteopathic physician (DO): A physician with much of the same function as a medical doctor (MD) but who takes a more holistic approach that includes proper alignment of bones, muscles, ligaments, and nerves. Chiropractics: A system of therapy based on the theory that disease is caused by pressure on the nerves. Chiropractic treatment most often involves physical manipulation of the spine.

  3. Musculoskeletal Anatomy TermsTissue Types Oste/o: bone Fasci/o: band or fascia Fibr/o: fiber or fibrous tissue Leiomy/o: smooth muscle Muscul/o or my/o: muscle Myel/o: Bone marrow or spinal cord Ten/o, tend/o or tendin/o: tendon Chondr/o: cartilage

  4. Musculoskeletal Anatomy TermsSkeletal System – upper extremities Phalang/o: phalanges (bones of the fingers or toes) Metacarp/o: metacarpus (hand bones) Carp/o: carpus (wrist bones) Humer/o: humerus *scapul/o, clavicul/o, radi/o, uln/o etc.

  5. Musculoskeletal Anatomy TermsSkeletal System – lower extremities Phalang/o: phalanges (bones of the fingers or toes) Calcane/o: calcaneum (heel bone) Fibul/o: fibula (smaller outer bone of the lower leg) Tibi/o: tibia (larger inner bone of the lower leg) Patell/o: patella (kneecap) Femor/o: femur (thigh bone) Pelv/i or pelv/o: pelvis

  6. Muscles and Bones Muscles attach to other muscles by ligaments Muscles are attached to bones by tendons. Contraction of the muscle moves bones at the joint. In this example, when the arm muscle (E) contracts, the elbow joint (F) flexes, and the hand (L) is lifted.

  7. Musculoskeletal Anatomy TermsSkeletal System – axial skeleton Cervic/o: neck Cost/o: ribs Crani/o: cranium or skull Spondyl/o or vertebr/o: vertebra (backbone) Lamin/o: lamina (part of vertebral arch) Stern/o: sternum (breastbone)

  8. Cervix - “neck” Thorax - “chest” Lumbar - “loin” Sacral - “holy” • 5 sacral vertebrae, fused Coccyx - “tailbone”

  9. Other Important Musculoskeletal Terms Orth/o: straight Ankyl/o: stiffness, bent, crooked Arthr/o: joint -clasia or -clast: to break -desis: binding or fixation of a bone or joint -malacia: softening -physis: growth -porosis: porous

  10. Musculoskeletal Pathology Terms Strain: Trauma to a muscle from overuse or excessive forcible stretch Sprain: Trauma to a joint that causes injury to the surrounding ligaments Tendonitis: Inflammation of a tendon usually caused by injury or overuse

  11. Musculoskeletal Pathology Terms Musculotendinous injury: damage to the muscles and tendons. Rotator cuff tears are a good example. The cause of this is complete abduction of the shoulder, followed by a rapid and forceful rotation and flexion of the shoulder Crepitation: Grating sound made by movement of bone ends rubbing together

  12. Musculoskeletal Pathology Terms Contracture: Fibrosis of connective tissue in skin, fascia, muscle or joint capsule preventing normal mobility Torticollis: Spasmodic contraction of the neck muscles causing stiffness and twisting of the neck. Myasthenia gravis: An autoimmune neuromuscular disorder characterized by muscular weakness and progressive fatigue.

  13. Musculoskeletal Pathology Terms Osteoporosis: Decrease in bone density and an increase in porosity. Bones become brittle and the risk of fractures increases. Rheumatoid arthritis: Chronic, systemic disease characterized by inflammatory changes in joints and related structures. Results in crippling deformities. Gout: Hereditary metabolic disease that is a form of acute arthritis. Characterized by excessive uric acid in the blood and around joints.

  14. Musculoskeletal Pathology Terms Ewing Sarcoma: Malignant growth found in the shaft of long bones that spreads to the periosteum Paget Disease of Bone: Skeletal disease of the elderly with chronic inflammation of bones. Results in thickening and softening of bones and bowing of long bones. Also called Osteitisdeformans

  15. Musculoskeletal Pathology Terms Rickets: Softening of the bones due to vitamin D deficiency, most often seen in children. Vitamin D is required for calcium absorption. Talipesequinovarus: Congenital deformity of the foot. Also called clubfoot. Muscular Dystrophy: Group of hereditary diseases characterized by gradual atrophy and weakness of muscle tissue. Duchenne type is the most common.

  16. Musculoskeletal Pathology Terms Kyphosis: Increased curvature of the thoracic section of the vertebral column. Can cause hunchback or humpback. Lordosis: Forward curvature of the lumbar spine. Sometimes called swayback. Scoliosis: Lateral curvature of the spine. Ankylosingspondylitis: Chronic inflammatory disease of unknown origin that first affects the spine and is characterized by fusion and loss of mobility of two or more vertebrae; also called rheumatoid spondylitis

  17. Musculoskeletal Pathology Terms Ankylosingspondylitis: Chronic inflammatory disease of unknown origin that first affects the spine and is characterized by fusion and loss of mobility of two or more vertebrae; also called rheumatoid spondylitis. Spondylolisthesis: Partial forward dislocation of one vertebra over the one below it, most commonly the fifth lumbar vertebra over the first sacral vertebra; also called spinal cord compression

  18. Musculoskeletal Pathology Terms Herniated disk: Herniation or rupture of the nucleus pulposus (center gelatinous material within an intervertebral disk) between two vertebrae. Carpal tunnel syndrome: Pain or numbness resulting from compression of the median nerve within the carpal tunnel (wrist canal). Sequestrum: Fragment of necrosed (dead) bone that has become separated from surrounding tissue

  19. Musculoskeletal Pathology Terms Osteoporosis: Increased osteoclastic activity leading to decreased bone density. Osteosclerosis: Hardening of the bones (too much osteoblastic activity) Osteomalacia: Softening of the bones (too much osteoclastic activity)

  20. Musculoskeletal Pathology Terms Subluxation: Partial or complete dislocation Fractures Compound/open: A fracture in which the broken end of a bone has been moved, so that it pierces the skin. There may be extensive damage to surrounding blood vessels, nerves, and muscles Impacted: Type of fracture in which broken ends of bone are forced into one another.

  21. Musculoskeletal Diagnosis and Treatment Diagnosis is almost always made through the use of radiography. Don’t forget the radiography terms as well as the directional terms. Arthrocentesis: Puncture of a joint space with a needle to remove fluid. Arthroplasty: Surgical reconstruction of a joint. Total hip replacement: Replacement of the head of the femur and acetabulum with metal components to make a new hip joint
