Surgical treatment is preferred to correct structural shortness and length; functional shortness and length mainly rely on conservative treatment such as daily exercise.
Clinically, there are two possible reasons for the double lower limbs not being the same length, i.e. structural or functional factors.
Structural short and long legs are mostly caused by deformed healing of fractures, which can only be corrected by surgical osteotomy.
Functional short legs are more common in clinical practice, and the main principle of correction is to correct the primary cause of the disease, such as the imbalance of the muscle strength of both lower limbs, in order to obtain corrective results.
Commonly used methods include exercise and wearing braces. Exercises such as running and swimming, combined with stretching, can often help to correct the problem to a certain extent, and bracing is even more effective.
Patients with short and long legs should seek immediate medical attention to determine the best course of treatment based on the cause of the condition in order to achieve the best possible correction. It should be noted that exercise should be performed under the supervision of a medical professional to avoid unnecessary injuries.
