Ankle-foot orthosis after burn
Technical Field
The utility model relates to an ankle joint orthopedic device, concretely relates to ankle foot orthopedic ware after burn.
Background
After ankle and foot burn, foot drop is easily formed along with the healing process of the wound surface, and after the wound surface is healed, the wound surface is used as a scar of common burn sequelae, and the scar is accompanied with hyperplasia contracture of the scar, so that foot drop can be further caused, ankle joint movement disorder is caused, and the walking function of lower limbs is seriously influenced. The continuous and good body position placing is the first step of the recovery of the burn patient and is the first defense line for preventing joint contracture. After the ankle joint is burnt, the early orthopedic device can effectively keep the ankle joint in an anti-contracture position or a functional position, and can prevent foot drop. The scar hyperplasia at the later stage is contracture, and the orthopedic device can treat foot drop by pulling the contracture scar. The ankle-foot orthotics on the market can play a certain role, but have the defects of treating foot drop caused by burn. The wound surface is not healed in the early stage of burn, dressing change and bandaging are often needed, and the circumference can be greatly changed by performing thin or thick wrapping according to the condition of the wound surface. The commercially available ankle-foot orthotics have limited adjusting range, and are easy to cause wound compression after dressing change to influence wound healing. And then, the market ankle-foot orthosis treats foot drop caused by ankle scar contracture, so that the situation that the lower leg part slides down due to the fixed support is easy to appear, the drafting force of the ankle joint scar is insufficient, and the good treatment effect is not achieved. In addition, the foot support is not pressed against the bottom of the foot, so that the foot bottom of a patient is stressed unevenly, and local pain is easily caused. And the force of the ankle contracture scar part of the commercially available ankle-foot orthosis is insufficient, the adjustment is troublesome, and the numerical value of the angle change is not objectively recorded.
