What does lower limb deformity correction involve?
Lower leg deformities are corrected using a procedure called osteotomy. This entails making a cut to the bone and then realigning bones and joints so they are correctly positioned. They are then stabilised, in some cases using an external fixator, as in limb lengthening surgery. A fixator is a frame that attaches to the end of the bone, keeping it in the correct position and allowing new bone to grow to fill any gaps. Osteotomies are an effective method of joint preservation. By realigning the joints so they are working correctly the procedure helps to prevent any further joint damage.

Why might I need lower limb deformity correction?
You might be offered this type of surgery if you have had lower limb deformity since birth or early childhood, or if you have developed the condition as a result of an accident or injury. Deformities in children are often caused by genetic abnormalities, the position of the foetus in the womb or nutritional deficiencies.

Among the conditions that might be suitable for this type of surgery are:

• Club foot (congenital talipes equinovarus) which is a congenital abnormality that causes a child’s foot to twist inwards at the ankle.
• Flat foot or fallen arches (pes planus) which is a condition where the natural arch of the foot fails to develop or collapses.
• High arch which is a condition that causes the foot arch to become abnormally pronounced, causing pain in the ball and heel of the foot.
• Tarsal coalition which is where two or more tarsal bones fuse.
• Bowed legs (congenital genu varus) which causes an abnormal outward curve in one or both legs.
