The stretching process begins on the seventh day after the fixation procedure.
This is a fixator made by Dr Doan and the research team of 108 Military Central Hospital. The fixator is dedicated only for leg stretching. It was registered and licensed at the Intellectual Property Office of Viet Nam – Ministry of Science and Technology. The fixator is designed for simple operation, consisting of 3 pile rods with opposite threads. The stakes are connected with 2 semicircular rings at the 2 ends. Each semicircle holds 2 small nails pierced through the bone. At the center of the rods are the sides that form a hexagon. Therefore, it can be adjusted to stretch or squeeze easily when desired. Turning one round is to stretching or squeezing in 2mm, so turning 3 sides a day is equal to 1mm and turning 1 side is equal to 1/3mm. To further understand how to stretch, please watch the detailed video below with specific instructions from Dr. Doan.
