The effect of minimally invasive stovepipe surgery can be maintained for a long time and is not easy to rebound. Because the principle of stovepipe is to find a breakthrough from the source, that is, to selectively cut off some nerve branches that dominate the gastrocnemius of the calf, so that the gastrocnemius gradually shrinks and achieve the purpose of stovepipe. Due to the difficulty and high technical requirements of minimally invasive stovepipe surgery, doctors are required to have a solid anatomical foundation, skilled surgical techniques and rich experience in orthopedic surgery. Therefore, surgery must be carried out in a regular plastic surgery hospital.
