Long or Tubular
Short or Cuboidal
cube shaped found in the carpal bones of the wrist and tarsal bones of the ankle

Short or Cuboidal
Sesamoid
short bone formed within the tendons, such as the patella

Sesamoid
Flat
layer of spongy bone between two thin layers of compact bone such as the skull and ribs

Nine Bone Fractures
Closed Fracture, Compound Fracture, Comminuted Fracture, Transverse Fracture, Greenstick Fracture, Spiral Fracture, Colles’ Fracture, Compression Fracture, Epiphyseal Fracture
Closed Fracture, Compound Fracture, Comminuted Fracture, Transverse Fracture, Greenstick Fracture, Spiral Fracture, Colles’ Fracture, Compression Fracture, Epiphyseal Fracture
Nine Bone Fractures
Closed Fracture
does not involve a break in the skin
does not involve a break in the skin
Closed Fracture
Compound Fracture
involves a break through the skin increasing the possibility of infection
involves a break through the skin increasing the possibility of infection
Compound Fracture
Comminuted Fracture
more than two separate bone components, segmental fracture, bony fragments
more than two separate bone components, segmental fracture, bony fragments
Comminuted Fracture
Transverse Fracture
breaks the shaft of a bone across the longitudinal axis
breaks the shaft of a bone across the longitudinal axis
Transverse Fracture
Greenstick Fracture
only one side of the shaft is broken, and the other is bent; common in children
only one side of the shaft is broken, and the other is bent; common in children
Greenstick Fracture
Spiral Fracture
spread along length of bone and produced by twisting stress
spread along length of bone and produced by twisting stress
Spiral Fracture
Colles’ Fracture
occurs in the wrist and affects the distal radius bone
occurs in the wrist and affects the distal radius bone
Colles’ Fracture
Compression Fracture
occurs in vertebrae and is subject to extreme stress
occurs in vertebrae and is subject to extreme stress
Compression Fracture
Epiphyseal Fracture
occurs where the matrix is undergoing calcification and chondrocytes are dying; usually seen in children
