A double osteotomy combines the DFO and HTO procedures in order to realign the bones on either side of the knee joint. The surgery is performed when single osteotomy above or below the joint will not adequately address the deformity. Titanium plates securely hold the bone until healing occurs.
A double osteotomy combines an HTO and a DFO in one operation to realign the knee and reduce the pressure on the damaged joint. It is most commonly performed where there is a more severe deformity in the limb and where the deformity lies in both the femur and the tibia. If all of the correction in a severe deformity is performed in just one bone there is a risk of poor outcome because the joint line may not remain horizontal. The knee will need to be carefully assessed in order to determine whether double osteotomy is a suitable treatment. Mr Dawson has researched accuracy in this procedure and now regularly uses the NuVasive nail in double osteotomy. This allows post-operative correction to fine tune the accuracy achieved.
Osteotomy is a procedure that involves cutting bone and then fixing the pieces created into new positions. The commonest procedures are called opening or closing wedge osteotomies. In these operations the bone which is cut is left connected at a hinge about which the bone pieces are corrected by rotation of around 5-15 degrees. In opening wedge osteotomy a gap is created by separating the cut surfaces held at one side by a hinge. The gap created is often filled with bone graft. In a closing wedge osteotomy a small wedge of bone is removed and the gap created closed down so that the surfaces meet - the hinge remaining intact. The operation will be carefully planned so that the bone can be positioned correctly in order to redistribute the weight borne by the knee.
