Physiology
Bone fractures
Spiral fracture:
Fracture occurring when a rotating force is applied to axis of a bone
Comminuted fracture:
Break or splinter of the bone in more than two fragments
Transverse fracture:
Broke bone where its broken at a right angle ti the long plane of bone
Impacted fracture:
When the broken ends of the bone are jammed together by a force
Compound fracture:
Broken bone pierces the skin, risking infection
Greenstick fracture:
One side of the bone is broken and the other only bent
Simple Fracture:
A fracture to the bone only, without damage to the skin
Oblique fracture:
Bones breaking diagonally
Epiphyseal plate
: Area of hyaline cartilage in immature bone where osstification occurs
Hypertophy:
Chondrocytes mature here and lacuna starts to erode
Calcification zone:
Dead chondrocytes are found here, penetration of caplilaries and connection of plate to diaphysis
Proliferative zone:
Chrondrocytes make new chondrocytes to replace the dying ones
Ossification zone:
Osteoblast secretes bone tissue on the remaining calcified cartilage
Found in Metaphysis at ends of long bones
Epiphyseal disk: Allows for continuous growth
In children
Epiphyseal line: Happens when bone stops growing in diameter
In adults
Secondary ossification
Hyaline cartliage:
Strong pliable support and protection
Metaphysis:
Region found between diaphysis and epiphysis
Found in
long bone
Greater in length and width
Bone Healing
Cartilage replacement:
Cartilage is replaced by trabecular bone
Remolding:
Compact bone replaces trabecular/spongy bone on the outer surface of the bone
Fibrocartilagneous
: Internal and external callus formation
Fracture hematoma:
Helps to stabilize blood supply with a cartilage seal
Mesenchymal cells
: Are multipotent stromal cells that differntiate into a variety of cell types
Chrondorcytes: A cell which has secreted the matrix of cartilage, now embedded in it
Systems
Integumentary: First of line of dense, prevents water loss and sensation
Skeletal: Support, movement, stores calcium, hemapoeisis
Endocrine: Slow communication through hormones
Periosteum:
Tough membranous sheath covering outer surface of bone
Periosteal collar:
A collar of compact bone around the diaphysis of the cartilage model
Compact bone: Dense or cortical bone
Long bone: Greater in length than in width
Diaphysis: Compact bone with thin spicules of spongy bone extending inward
Medullary cavity: Hollow, cylindrical space of diaphysis, contains marrow
Red bone marrow: Found in children
Yellow bone marrow: Found in adults
Epiphysis: Knobby region of at each end of long bone
Metaphysis: Contains epiphyseal plate/disk used of growth
Osteoblasts: The bone builder
Osteoid:Unmineralized organic component of bone
Collagen protein
Osteocytes: The regulator cell, maintain mineral concentration
Lacunae
Canaliculi: Tiny, interconnecting channels, connects lacunae. Allows exchange of nutrients.. etc
Osteogenic cells: Stem cells derived from mesenchyme, and mature to osteoblast
Osteoclasts: Bone resorption, breaks down old or damaged bone and releases calcium in the blood
Growth
Mechanical stress:Increase in bone strength
Vitamin D: Produced by the body, triggered by sun
Calcium: is absorbed into the body
Inorganic compounds: Mostly calcium, hardens matrix
Organic compounds: Collagen protein, gives bone tensile strength by resisting stretching
Dense bones
Lack of dairy consumption
Does not compensate for what you loose
Bones begin to lose calcium
Bones become weak
Liable to more breaks
Infection
Compound fracture
Bones pierce the through skin
Elbow and upper arm
Open wound
Liable for bacteria to get in
Bone fractures
Upper arm
Destruction of surgical neck
Compound fracure
Piercing though skin
Open wound
Infection
Elbow
Dislocation of Humerous
Parts of Ulna and Radius
Skeletal system
Broken bone
No support
Lose of movement
Lack of calcium
Age
Boy is 12 years old
Bones are not mature
Still growing
Not as strong
Libale to break
