The main objective of treating fractures is to enable the patient to return to normal function as soon and as safely as possible. The 4 principles of managing fractures include resuscitation, reduction, restriction (holding reduction) and rehabilitation. Treating the fracture can be done either operatively or non-operatively, each with its own advantages and disadvantages.
Following the ATLS protocol, treat life-threatening and limb-threatening injuries
Reduce
Adequate apposition and anatomic/mechanical alignment of the bone fragments
Restrict (Hold)
Appropriate immobilisation and fixation of the fracture fragments. Hold the fragments together in place until they unite.
Rehabilitate
Early mobilisation of the patient through physiologic loading of the bone via muscle activity or early partial/full weight bearing.
Reduction
Reduction is adequate apposition and anatomic/mechanical alignment of the fracture fragments. The bones are adequately aligned so that they heal in a position that is optimum for function. Extra-articular fractures usually require mechanical alignment, focusing more on alignment, length and rotation. Intra-articular fractures require anatomical alignment to restore normal joint movement and avoid post-traumatic osteoarthritis.
Open or closed reduction can be performed. The general principle
Situations where reduction is unnecessary
Little or no displacement
When displacement does not matter initially (fracture of the clavicle)
When reduction is unlikely to succeed (fracture of the vertebrae)
Three-fold manoeuvre for closed reduction
Pull the distal part of the limb in the line of the bone
Reposition the fragments as they disengage (by reversing the original direction of force, which can be deduced)
