Fracture Displacemnt

 Introduction: According to displacement of fragments fracture classified into two                     groups 1-undisplaced fracture, 2-displaced fracture.  Any fracture when it is complete ,              fracture fragments may be displaced .

Causes of displacement: 1- Force of injury

                                           2- Muscle pull

                                           3- Gravity.

Types of displacement: 1-Translation or shift

                                       2- Angulation or tilt

                                       3- Rotation or twist

                                       4- Length descripancy 

Translation or shift: Fracture fragments when displaced in side ways, like forward,backward     , medial or lateral in relation to each other .Fracture surfaces may lose  contact between             them.When bone segments lie side by side fracture site may unite even fracture ends are         off-ended.

Angulation or tilt: Fracture fragments may angulated  in relation to each other.If                       malalignment not corrected ,which may lead to deformity in the limb.

Rotation or twist: One of fracture fragment may twisted on its long axis,If not corrected, may     lead to rotational deformity of the limb.

Leangth descripancy:  Alteration in length, may be shortening or lengthening .
