A&P 1: Chapter 7 Classification of Bone Fractures
Terms in this set (21)
Complete severing of a body part (typically toe or finger)
Fracture of the distal end of the lateral forearm bone (radius); produces a "dinner fork" deformity.
Bone is splintered into several small pieces between the main parts.
Bone is broken into two or more pieces.
Broken ends of the bone protrude through the skin.
Bone is squashed (may occur in a vertebra during a fall)
Broken part of the bone forms a concavity (as in skull fracture)
Fractured bone parts are out of anatomic alignment.
Epiphysis is separated from the diaphysis at the epiphyseal plate.
Partial fracture; one side of bone breaks - the other side is bent.
Fine crack in which sections of bone remain aligned (common in skull)
One fragment of bone is firmly driven into the other.
Partial fracture extends only partway across the bone.
Fracture is parallel to the long axis of the bone.
Diagonal fracture is at an angle.
Weakening of a bone caused by disease process (e.g., cancer)
Fracture is at the distal ends of the tibia & fibula.
Bone does not break through the skin.
Fracture spirals around axis of long bone; results from twisting stress.
Thin fractures due to repeated, stressful impact such as running (These fractures often are difficult to see on x-rays, & a bone scan may be necessary to accurately identify their presence.)
Fracture is at right angles to the long axis of the bone.
