Bone Kinetics - Coggle Diagram

- - - - Weight bearing
        
        Tension Superiorly
        
        Compression inferiorly
      - Gluteus Medius forces
        
        Compression superiorly
        
        Tension inferiorly
  - - - Minimum effective strain: 0.1% of length
  - - - Magnitude of strain
        
        Minimum effective strain
      - Rate of strain
      - Distribution of strain
    - - environment
      - age
      - number of loading cycles
      - mass needs of skeleton
      - skeletal damage/microdamage
      - Low serum calcium level (nutrition)
- - - - Area at each end of the bone
      - Osseous in adults
      - Two types
        
        Traction epiphysis
        
        Pressure epiphysis
    - - Cartilaginous area where growth occurs in long bones
      - Replaced by bone once growth has ended
    - - Main shaft of bone
      - center is medullary canal
    - - the flared part at the end of the diphysis
    - - lines the medullary canal
    - - outermost covering of bone
  - - - stem cells derived from mesenchyme
    - - produce new bone
    - - Mature bone cells
    - - involved in bone resorption
- - - - Makes up 40% of dry bone tissue (remove water)
      - Primarily Type I
  - - - PGs strongly bind to HA due to osteoclacin
- - - - Inflammation/Hemotoma
      - Soft callus Formation
      - Hard (bony) callus formation
      - Remodeling of callus
    - - Intramedullary bridging
        
        Functional bracing
        
        allows small degrees of movement
      - External callus bridging
        
        Casting
        
        Stable Fx
      - Primary cortical union
        
        Internal fixation
        
        ORIF- screws and plates
