A detailed introduction of foot prosthesis

Part of the foot prosthesis is also called "fake half foot", which is used for amputation of different parts of the foot due to trauma or disease

Part of the foot prosthesis is roughly divided into four types: foot cover type, shoe type, calf type, partial foot prosthesis and decorative toe cover.

Decorative toe covers, also known as false toes, are used for patients with partial or full toe amputation. Because patients who have lost toes, if the soles of the feet are not painful, they can generally walk in ordinary shoes. Therefore, the artificial toe cover made of silicone rubber or polyvinyl chloride resin molding is used to cover the residual foot only for decorative purposes. .

Foot sleeve partial foot prosthesis, also known as foot sleeve prosthetic half foot, is used for patients with plantar amputation or metatarsal joints. Its role is mainly to fill vacancies. The traditional method is to make the residual foot receiving cavity with leather according to the plaster type, and then glue it with the rubber foot end with the bottom leather pad and sponge (compensation tarsal and metatarsal joint) and other materials, open on the back or side, and use a belt Tighten and fix. It is mostly made of polyurethane resin molding, which is not only light in weight, easy to clean, but also good in appearance, making it easier to wear various shoes.

Shoe-shaped partial foot prosthesis, also known as boot-shaped prosthetic half foot, is a partial foot prosthesis used in conjunction with orthopedic shoes. It is mostly used for patients with plantar amputation, tarsal-plantar joint disconnection, plantar pain or foot deformities. It can also be customized according to the requirements of patients (especially those who are used to wearing leather boots). The difference between it and ordinary orthopedic shoes is that this kind of shoes must have the compensation function of the tarsal and metatarsal joints; and when it is difficult to step back when walking with this kind of shoes, a boat-shaped sole (shake the palm) can be added to the sole of the shoe.

The calf partial foot prosthesis is a product that is combined with a calf orthosis or a calf prosthesis. It is mostly used for patients with severe functional loss or foot deformities after partial foot amputation. Such as tarsometatarsal joints disconnected, attached to amputation. After this kind of amputation, the heel is often inward and backward, and the weight-bearing function of the stump is not good (the stump is painful when stepping on the floor and the skin is easy to break). In this case, partial foot prosthesis of calf orthosis or calf prosthesis should be used. In the past, the calf orthosis type mostly used the bracket type. The receiving cavity was made of leather, which was bonded to the rubber forefoot as a whole, and then reinforced with metal braces, and fixed on the calf with a tightening band. It has the disadvantage of heavy weight and easy atrophy of calf muscles. Now it is mostly made of thermoplastic sheets, such as shoehorn. When the residual limb cannot bear weight, it is necessary to use the patellar ligament to bear the weight as in the production of the calf prosthesis. The receiving cavity has a window according to the method of the Sym prosthesis, and the forefoot is made of polyurethane or rubber. This partial foot prosthesis can actually be regarded as a special calf prosthesis.
