External Fixation Device

An external fixation device is used to keep fractured bones stabilized and in alignment. The device can be adjusted externally to ensure the bones remain in an optimal position during the healing process. This device is commonly used in children and when the skin over the fracture has been damaged.

An external fixator is a useful tool in the management of fractures and certain difficult orthopedic problems such as limb length discrepancy. 

In the case of pelvic fracture it may be a primary life-saving device. With external fixation, pins and/or wires are percutaneously inserted into the bone and held in place by an external frame.

External fixation is most successful in superficial bones like tibia than deeper bones like femur or humerus – here the chance of pin tract sepsis is greater.

External fixators consist of modular components which are assembled to form a stable construct between bone fragments and an adjustable beam system. The beam system is joined to the bone by means of a number of pins screwed into the bone.
