Malalignment Disorder or Rotational Deformity is generally caused due to a rotation of either the femur (upper leg bone) or the tibia (lower leg bone). As stated by renowned trauma implants and spine Implants specialists such sight can be unpleasant and difficult to watch and can occur after either closed or open treatment of fractures.

In most cases, these irregularities are preventable despite the method of treatment used. As the top ortho surgical implants company, we have witnessed that these deformities may also develop in the process of intramedullary nailing of a fracture or from the use of external fixation devices, or also from cast or brace stabilization.

Spine Implants experts believe that rotary deformities can be cured by using a closed method of treatment. This method is based on monitoring the attitude, landmarks, and curve of the opposite normal extremity and their imitation in the injured limb. Any failure in the imitation can simply result in the creation of everlasting rotary deformities.

Most tibial fractures that are marked with associated fibular fractures have an external rotation deformity in the beginning, but those with an intact fibula are more likely to have internal rotation deformities. This happens as the fibula is slightly after the tibia and hence it forces the tibia to rotate on the unbroken fibula in an internal rotation direction.

Over the years, we have seen that there is a greater frequency of external rotation in such fractures. Our orthopedic implants expert believes that this is due to a very huge margin of tibia fractures that have a rotational stress component in their production, thus contributing to the greater frequency of external rotation in such cases. As soon as the rotational deformity is fixed and aligned in the long-leg plaster of Paris mold, it is very likely that the correction can be maintained. This can occur once the extremity is relocated to the below-the knee functional strut.

Over the past few years, we have conducted many pieces of research on the rotational deformity and found that ortho surgical implants, scientists use a method that consists of testing the rotary motion of the hips. They further analyze the difference between the motions of the two hips to estimate the degree of internal or external rotation at the fracture site. Assuming that the movements of hips are normal, the result of equally internal and external rotation in both the hips would indicate that no malrotation was found at the fracture site. In this method, any irregularity in the angle of rotation can be estimated and if found, is said to be equal to the malrotation at the fracture site. As a leading Orthopedic implants manufacturer in India, we have seen that rotational deformities are easily preventable and, if found, they rarely exceed 10°. Most deformities are in the 5-10° range. Under these circumstances, it is tricky to get acquainted with their existence by simply observing the patient gait.
