Whether the prosthetic gait is good-looking is not only related to the product, but also has something to do with the doctor's surgery.
Many amputation patients and their families have a common misconception: they believe that the gait of wearing a prosthetic limb after surgery will be natural and beautiful, and it is enough to choose a high-end, well-fitting prosthetic limb. However, in actual rehabilitation, this situation often occurs—imported prostheses that cost a lot of money to customize are still stiff in gait, walking in circles, uneven, and even accompanied by pain and discomfort.
In fact, The fitting effect of prostheses is half hidden in the product and half hidden in the surgery . In particular, the length of the residual limb after amputation directly determines whether the prosthetic limb can perform optimally. It can be called the "invisible key" that affects the aesthetics of gait.
为什么残肢长度如此重要？ Simply put, the residual limb is the "bridge" connecting the human body and the prosthetic limb. Its length directly affects the force distribution, control flexibility and stability of the prosthetic limb. A residual limb that is too long may lead to insufficient space for prosthetic assembly and limited joint movement; while a residual limb that is too short is a core problem that affects gait ——Not only will it greatly reduce the ability to control the prosthetic limb, causing the body to shake and shift the center of gravity when walking, it will also put excessive force on the end of the residual limb, causing pain and wear. Even with the most advanced prosthetic limbs, it will be difficult to achieve a natural and smooth gait.
The ideal residual limb length needs to meet two conditions: first, to ensure postoperative wound healing and stable blood circulation, which is the bottom line of medical safety; second, to reserve enough "operating space" for prosthetic limb assembly, so that the joints, sockets of the prosthetic limbs and the residual limb can perfectly fit, maximizing the functional advantages of the product.
既然残肢长度如此关键，如何在手术前就做好规划？答案是截肢术前，医生与假肢技师的联合会诊。 Under the premise that medical safety is fully guaranteed, through joint evaluation by doctors and prosthetic technicians, the optimal length of the residual limb can be accurately planned based on the patient's physical condition and activity needs to avoid difficulties in subsequent prosthetic fitting due to too short a residual limb. At the same time, the impact of surgery on prosthetic limb assembly, such as the stress points of the residual limb, skin conditions, etc., can be predicted in advance to provide a more scientific basis for postoperative prosthetic customization. It can also allow patients to understand in advance the key points of the connection between postoperative rehabilitation and prosthetic limb use, reducing trial and error costs during the rehabilitation process.
The beauty and comfort of prosthetic gait are never the efforts of a single link, but the perfect combination of medical solutions and rehabilitation adaptation. For patients who are about to face amputation surgery, do not ignore the importance of preoperative consultation—when time and conditions permit, doctors and prosthetists can participate in the formulation of the plan, so that the residual limb can reach the best assembly state and lay a solid foundation for each subsequent step to walk calmly.
After all, a good prosthesis requires a suitable residual limb to carry it, and scientific preoperative planning is the first step to start a smooth gait.
