Deformity Correction

Deformity correction surgery is indicated when someone has a change in the shape of their bones which causes significant functional limitation or functional symptoms (i.e pain) or increases the risk for development of osteoarthritis in the future.

The correction of bone deformities is done by carefully cutting the bone (osteotomy) at certain point (or points) and then turning them back into the correct alignment.

Depending on the bone which is affected, the shape for the deformity and its severity, two main options are available: Gradual correction with a hexapod external circular frame and acute correction with plates or nails(usually with the use of Poller guiding screws).

Small deformities can be corrected acutely during the operation and the bone is fixed with internal fixation devices like nails or plates.
More complex or bigger deformities are corrected gradually with the use of special external fixators which allow the slow correction of the alignment. This is done because the nerves, vessels, tendons and muscles cannot be stretched too much too quickly.

Before the operation the surgeon reviews specialized x-rays and a CT scan in order to make decisions about the number and exact point of osteotomies, the fixation device and the rate of correction of the deformity. The correction of limb deformities is a prolonged process which requires expertise and dedication to succeed.
