For a long time, we have seen pediatric amputee and congenital anomalies, the socket is in normal condition but height of the prosthesis decrease due to the growth of the child after few months and few years they need to change the prosthesis. Hence, many companies are making different types of pylon tube but the problem is height adjustment is still ignored/compromised. In a simple pylon tube, we have to dismantle the full pylon tube then only we can adjust the height but in this design not need to dismantle the full pylon and prosthesis because we can adjust the height by rotating turnbuckle. A pylon tube is an important component of the transtibial prosthesis, which bears the weight of the patient. It influences the gait performance and comfort of the patient, where its flexibility can dictate the ground reaction forces associated with walking and step-down. Without an adjustable pylon, it is very difficult for congenital anomalies and pediatric amputee, so in this study, we are trying to adjust height with the growth of the child amputee. In this prosthesis has height adjustable option by rotating of turnbuckle, so we can do the height adjustment very easily. Patients can also increase/decrease their height by themselves, no require to visit clinic, so it may reduce time-consuming for patients as well prosthetist. To face these all challenges, we have designed and developed a new easily adjustable prosthetic pylon in a very low cost for lower-limb amputees.
