A limb deformity is a problem with an arm or leg that makes it crooked. This may include:
Some types of deformities do not need treatment and get better over time. Others may need surgery.
Post-Traumatic Limb Deformity
A post-traumatic limb deformity is a limb that becomes crooked after a bone is broken. In some cases, the bone may heal in a crooked position, which is called a "fracture malunion." Other times, the fracture may heal straight, but the bone’s growth plate is partially damaged. This causes the bone to heal crooked or grow to a different length than the opposite limb.
In children, fracture malunions are often not a problem if the crookedness is not causing any pain or the child can still use the limb normally. This usually happens if the fracture is close to the growth plate but does not affect the growth plate.
In some children, a crooked bone will not improve its alignment as it grows, and it becomes painful or causes functional problems. If this is the case, your child’s doctor can talk to you about options that are available to straighten the bone.
