Study Notes
Skeletal and Musculoskeletal System
- Osteology: Study of bone structure
- Musculoskeletal System: Integrated system of bones, muscles, and joints
- Orthopedics: Branch of medicine dealing with prevention, correction, and treatment of musculoskeletal system problems. (Ortho = to correct; Pedi = child)
- Hallux Valgus (Bunion): Angulation of the great toe away from the midline, often caused by tight shoes.
- Genu Varum (Bowlegs): Knees abnormally separated, medial angulation of the tibia to the femur
- Genu Valgum (Knock-knees): Knees abnormally close together, lateral angulation of the tibia relative to the femur
- Talipes Equinovarus (Clubfoot): Foot twisted inferiorly and medially; treated with corrective shoes or surgery.
- Pes Planus (Flatfoot): Weakened arches; can be flexible or rigid.
- Patellofemoral Stress Syndrome (Runner's Knee): Pain around the kneecap; can relate to genu valgum
- Boxer's Fracture: Fracture of the 5th metacarpal (bump on the side of the hand)
- Craniosynostosis: Premature closure of one or more cranial sutures, restricting brain growth
- Lumbar Spine Stenosis: Narrowing of the spinal canal, often due to hypertrophy or arthritic changes.
- Whiplash Injury: Hyperextension and hyperflexion of the head, often from rear-end collisions; stretches ligaments.
- Paget's Disease: Bone proliferation (increase) due to increased bone synthesis
Medical Conditions Affecting Bones
- Osteoarthritis: Degeneration of articular cartilage.
- Osteomyelitis: Infection in the bone, characterized by high fever, sweating, chills, pain, nausea, pus formation, and edema; often caused by Staphylococcus aureus
- Osteopenia: Reduced bone mass or reduced rate of bone synthesis
- Osteosarcoma: Connective tissue tumor affecting osteoblasts (bone cells); most common in adolescents during growth spurts, affecting the tibia/femur/humerus.
- Craniotomy: Surgical procedure on the skull; performed if blood clot, tumor, or for biopsy.
- Laminectomy: Procedure to remove a part of the lamina of the spinal column
- Spinal Fusion: Uses bone graft or synthetic device to stabilize the spine.
- Pelvimetry: Measurement of the birth canal inlet and outlet (using ultrasound or physical examination).
- Bone Grafting: Transferring bone tissue. Fibula is a common source.
Muscle Tone and Movement Disorders
- Muscle Tone: Degree of tension in muscles.
- Atonic: Lacking muscle tone.
- Rigidity: Stiff and inflexible muscles.
- Tremor: Involuntary muscle movements.
- Dystonia: Muscle contractions causing twisting movements.
- Tic: Involuntary muscle twitching.
- Contracture: Permanent shortening of a muscle or tissue.
- Spasm: Sudden, involuntary muscle contraction
- Cramp: Painful muscle spasm.
- Tetany: Muscle spasms due to low calcium levels.
- Fasciculation: Involuntary muscle twitches.
- Contustion: Bruise (injury to soft tissue)
- Origin: Point of muscle attachment to bone
- Strain: Overstretching or overuse injury to a muscle.
- Irritability: Ability of a muscle to be stimulated.
- Paralysis: Loss of movement.
Bone Surface Markings
- Fissure: Narrow slit
- Foramen: Opening through which blood vessels or nerves pass.
