Limb Deformity Correction
Limb deformity can occur for several reasons. It may occur following a fracture, if the bone fails to heal correctly. This can occur if the bone is not fixed in the correct position, or if the metalwork fails before full healing has occurred. This can lead to shortening of the limb or disruption in its normal weight bearing axis. Bones may fail to grow normally for a variety of reasons resulting in shortening of other deformity that can develop over time during childhood. These deformities can cause other problems over time, such as:
- A change in the normal walking pattern, such as a limp
- Pain referred to the hip, knee or ankle if the bone heals with an abnormal twist (rotational malalignment)
- increased pain through abnormal loading on joints due to alternation in the mechanical axis
- Stiffness in the joints around a deformity. Over time the normal flexibility of joints can be lost resulting in fixed deformities.
- A deformity in a fractured limb can result in non-union with subsequent metalwork failure
Sometimes a deformity may not be appreciated and may be missed following fracture surgery. Some cases are referred to use because they are considering a joint replacement due to arthritis secondary to a longstanding limb deformity. This prevents the joint replacement as the abnormal loading of the joint due to malalignment will result in early failure of any joint replacement undertaken. We can correct the deformity to allow joint replacement to be undertaken if required in the future.
Our comprehensive assessment will look to fully understand the extent of deformity so we can consider the best way of addressing the problem.
Most deformity correction will involve rebreaking the bone via a small cut. The correction of the deformity can then be made. Sometimes the correction can be performed straight away. However, it might be necessary to undertake the deformity correction over time. This is usually the case with correction of limb shortening or when an immediate correction would put too much pressure on important structures like nerves or blood vessels. If the deformity correction is undertaken gradually, it is usually performed using an external fixator. There are some instances where it is possible to use all internal fixation, such as with lengthening intramedullary nails, although this is not an option for all cases.
At the Oxford Limb Reconstruction and Infection Clinic we have developed techniques that combine internal and external fixation. This means that the duration of treatment required with external fixation can be significantly shortened, which makes treatment far more tolerable for the individuals we treat.
