  1. Bone compsosition

  2. Bone anatomy

  3. fracture • it’s the break in the continuity of the bone . it could be: • 1-simple(closed) • 2-compound (open) .

  4. Causes of fractures • 1- sudden truma • 2-stress’’fatigue fracture’’. • 3-pathological fracture.

  5. Types of fracture • Complete fractures • In-complete fractures • Physeal fractures • Fracture displacement

  6. Complete fractures: • Transverse fracture • Oblique or spiral • Impacted • comminuted

  7. Transverse fracture

  8. Oblique fracture

  9. Impacted fracture

  10. spiral

  11. Incomplete fractures • The bone is incompletely divided and the periosteum remains in continuity. • Exm:greenstick fracture. • Stress fracture • Compression.

  12. Fracture displacement • We describe it in terms of: • Translation ‘’shift’’ • Length • Alignment ’’angulation’’ • Rotation ‘’ twist’’

  13. Soft tissue damage • It could be either: • Low energey fractures like closed spiral fractures,and it coz moderate soft tissue damage. • High energy fractures:like comminuted fracturs and it coz severe tissue damage,no matter whether it open or close.

  14. Fracture healing • Healing by callus • Healing Without callus

  15. Time factor • The rate of the bone depends on: • 1-type of the bone. • 2-type of fracture. • 3- blood supply • 4-general constitution. • 5- pt age.

  16. Fractures that fail to unite(non union) • Distraction and separation of the fragments. • Interposition of soft tissues between the fragments. • Excessive movement at the fracture site • Poor local blood supply. • Severe damage to soft tissues which makes them non viable. • Infx • Abnormal bone.
