Fracture—break in a bone
Types of bone fracturesClosed (simple) fracture—break that does not penetrate the skinOpen (compound) fracture—broken bone penetrates through the skinBone fractures are treated by reduction and immobilization
Slide3Slide4Slide5Common Types of Fractures
Table 5.2
Slide6Comminuted fracture-bone breaks into many pieces. Common in older people with brittle bones.
Slide7Supracondylar fracture of humerous one of the most common childhood fractures
Slide8Comminuted fracture-bone breaks into many pieces. Common in older people with brittle bones.
Slide9Compression fracture-bone is crushed. Common in osteoporotic (porous) bones.
Slide10Depressed skull
Depressed fracture-broken bone portion is pushed inward. Typical of skull fracture.
Slide11Repair of Bone Fractures
Hematoma (blood-filled swelling) is formed
Break is splinted by fibrocartilage to form a callusFibrocartilage callus is replaced by a bony callusBony callus is remodeled to form a permanent patch
