Description

The flat pes valgus of a kind of child's flexibility is rescued and is used arch support
The present invention relates to technical field of medical instruments, specifically, is that the flat pes valgus of a kind of flexibility child is rescued and used arch support.
[background technology]
The flat pes valgus of child's flexibility is that one group of arch of foot during take non-heavy burden is normal and arch of foot flatly subsides while bearing a heavy burden, heel turns up as the morbid state foot of feature, modal mechanism is laxity of ligament, while causing bearing a heavy burden, astragalus tilts with vola to the inside on calcaneus, calcaneus revolves position front and in excessively turning up, and generation arch of foot is low puts down or subsides.While conventionally not bearing a heavy burden longitudinal arch of foot exist, but bear a heavy burden time can find longitudinal arch of foot reduce or disappear.Flat pes valgus can be divided into clinically to light-duty (longitudinal arch of foot reduction), medium-sized (longitudinal arch of foot disappearance) and heavy (longitudinal arch of foot disappearance, medial border of foot projection, articulatio talonavicularis dislocation, inside, the downward-sloping dislocation of head of talus, head of talus is displaced to the front lower place of internal malleolus).
How asymptomatic flat pes valgus child is in early days for flexibility, while often standing because bearing a heavy burden, heel turns up without arch of foot, during walking, biped is skimmed outward, abnormal gait just causes that the head of a family notes, but along with child age, body weight and momental increase, there will be gradually ankle pain and calf discomfort, may affect motion, quality of life is caused and had a strong impact on.In recent years people are to the corresponding raising of the attention degree of the flat pes valgus of child, and its expectant treatment method can be divided into:
1) orthopedic shoe: make a little higher than outside of thickness inside sole, make outside of foot stressed more, the pressure of longitudinal arch in reducing.What in recent years occur is negative with footwear, and sole is low after front height, again the pressure of longitudinal arch of foot is shifted to calcaneus on this basis, in the hope of farthest alleviating longitudinal arch of foot pressure.No matter which kind of designs, and object is all the pressure in order to reduce longitudinal arch of foot, alleviates the vola pain and the shank discomfort that because longitudinal arch of foot pressurized is excessive, cause.Shortcoming: 1. child's flat foot exists constitutional laxity of ligament, how with valgus calcaneus, medial border of foot projection (head of talus is displaced to the front lower place of internal malleolus for articulatio talonavicularis dislocation, inside, the downward-sloping dislocation of head of talus).For the displacement of foot bones, only depend on the decompression of medial plantar pad and upper of a shoe constraint, often can not control, and raise by force vola front portion, also can make calcaneus bear larger pressure, may increase the weight of valgus calcaneus, increase the weight of the displacement of head of talus, its " orthopedic effect " remains query.2. orthopedic shoe will fit and just can bring into play desirable effect very much, buys the orthopedic shoe fitting, and must need to renew footwear after the 3-6 month, increases the financial burden of family, and if according to General Requirements, go out greatly a finger while buying new footwear, orthopedic effect is just difficult to guarantee.
2) arch support and orthopedic insoles: arch support or orthopedic insoles are placed on that sole is inner to be used, and quality requires certain hardness and thickness, make it to be placed under longitudinal arch of foot can rigid picking-up it, make the skeleton that forms longitudinal arch of foot be tending towards normal alignment.Arch support or the arch support of flatfoot are multifarious on the market at present, its shortcoming comprises: 1. to the Pathophysiology feature of flat pes valgus, understand insufficient, there is constitutional laxity of ligament in the flat pes valgus of child, from longitudinal arch of foot below, pave, raise longitudinal arch of foot merely, make originally lax ligament for a long time in passive extended state, lack active exercise, may run counter to desire, ligament can be more and more lax.2. much more remarkable the flat pes valgus degree of child is, has medial border of foot projection, articulatio talonavicularis dislocation, and inside, the downward-sloping dislocation of head of talus, head of talus is displaced to the front lower place that sufficient sole of the foot side is internal malleolus.In this case, from below, pave longitudinal arch of foot merely, not only can not make articulatio talonavicularis reset, may also can increase the weight of the displacement of astragalus, increase the weight of pathological changes.3. arch of foot is paid somebody's debt and expected repayment later can increase the stressed of vola sole of the foot fascia, makes user feel vola pain, may be because sole of the foot fascia has been subject to unreasonable tractive for a long time, causes the lax of plantar aponeurosis, increases the weight of flatfoot.
In sum, need a kind of rectification means badly more scientific and reasonable, effect is more remarkable, and untoward reaction is few, and comfort level is high, the economical and practical flat pes valgus rectification of child's flexibility apparatus.
