Osteotomy surgery

Osteotomy surgery is an operation used to change your bone's length or alignment.

Osteotomy surgery is an operation whereby a bone is cut to shorten, lengthen, or change its alignment. The procedure can be performed to correct a coxa vara (a rare hip condition), treat hallux valgus (bunions), or straighten a bone that has healed crookedly following a fracture. 

The operation is carried out under a general anaesthetic. During the recovery period for an osteotomy, specialist equipment can be used to support your recovery and help you perform your day-to-day tasks. These include specialised walkers and wheelchairs and mobility aids such as dressing sticks or long-handled shoe-horns.

A coxa vara is the deformity of the hip, whereby the angle between the ball and the shaft of the femur is reduced. This results in the leg being shortened, and therefore a limp occurs. It is commonly caused by injury, such as a fracture. It can also occur when the bone tissue in the neck of the femur is softer than normal, meaning it bends under the weight of the body.

This condition can either be congenital, also known as Mau-Nilsonne Syndrome, or the result of a bone disorder. Symptoms include pain, stiffness, and difficulty in walking. It is diagnosed by an X-ray. In most cases osteotomy surgery can ease the condition.

During osteotomy surgery, your bones are exposed surgically and divided with specialist equipment. The cut ends are realigned into the correct position and held with plates and screws or metal rods (intramedullary nails).

An abnormal hip anatomy can be present from birth but you might not be aware of this. The most common conditions which are treated are a hip dysplasia (shallow hip), slipped upper femoral epiphysis and subtle abnormalities in the shape of the femur (thigh) bone.

An osteotomy is an appropriate procedure for patients who are less than 40 years old. If you have signs of arthritis or inflammatory joint disease, you will not be advised to have this procedure. You will also not be recommended this procedure if you are a smoker due to poor bone healing in smokers.

Like all major lower limb surgery, there is a risk of developing a blood clot. An infection is another possible risk that could occur post-surgery and you may need further surgery to treat an infection.

Your Consultant will explain whether an osteotomy is an appropriate treatment option for you and discuss the risks and benefits associated with this procedure.

If successful, an osteotomy could stop your hips from becoming arthritic and the need for treatments such as a hip replacement or resurfacing.

At your consultation, your Consultant will discuss with you, your symptoms and help confirm a diagnosis. They will then work with our multidisciplinary team of specialists consisting of nurses, physiotherapists and orthopaedic Consultants to create a treatment plan that best suits your needs and requirements.
