Description
Technical Field
The utility model relates to the technical field of correction instruments, in particular to a hallux valgus orthosis for correcting collapse of a transverse arch and a longitudinal arch.
Background
Hallux valgus, commonly known as the "big foot", is a common deformity of the forefoot in which the hallux leans outward of the foot and the 1 st metatarsal adduction. The etiology of the disease is related to heredity and wearing discomfort, more than 80% of the disease has family history, and women are more frequent. There is a strong ligament bond between the foot wedge and the metatarsal, but the medial wedge is weaker than the other wedge to the 1 st metatarsal. If the user stands too long, walks too much and wears high-heeled shoes or pointed shoes frequently, the pressure born by the inner wedge bones and the metatarsal bones exceeds 25 percent, so that the first metatarsal bones are promoted to move inwards, and the longitudinal arch and the transverse arch of the foot are caused to collapse. (the total of 3 cuneiform bones participates in forming the transverse arch of the foot and also participates in supporting the medial longitudinal arch of the foot, plays a key role in the transmission of force, is an important osseous structure of the midfoot and is also an important component for maintaining the normal function of the foot.) the thumb moves outwards due to the traction of the adductor hallux and extensor hallux, and the included angle between the 1 st and 2 nd metatarsal bones is increased. The 1 st metatarsal head forms a osteophyte on the inner side of the foot, the eversion is gradually aggravated, the 2 nd toe is extruded to the back side by the 1 st toe, and the interphalangeal joint is flexed to form a hammer toe.
Treatment: the non-operative treatment method can be used for non-operative treatment of mild deformity and symptoms of the patient with serious symptoms. Many appliances are available to prevent the development of hallux valgus. The slight eversion can be applied to a silica gel toe separating pad or toe separating footgear between the 1 st toe and the 2 nd toe, and can also be applied to hallux valgus orthotics, orthopedic shoes or flat foot insoles for correction.
The utility model is implemented by arranging a thumb part and a tail finger part on one side of a sole part and arranging a force-bearing part in the thumb part, so that when a user wears the hallux valgus corrector, the thumb is corrected under the action of the force-bearing part, and the sole part for the penetration of the sole is also arranged, but the sole part is not added with a transverse arch and a longitudinal arch module, and the correction effect of a patient combining the collapse of the longitudinal arch and the transverse arch of the foot is poor.
The patent CN218165448U, a hallux valgus corrector, is a device in which the correction angle of the thumb of the device can be adjusted only in the horizontal plane, but the midfoot region lacks the transverse arch and the longitudinal arch of the foot to collapse and correct, the comfort level is reduced during the walking process of the patient, and the device is inconvenient to wear shoes due to the complex joint structure.
The utility model relates to a patent CN 214317196U, namely a special foot pad for hallux valgus, which is manufactured by adopting a carbon fiber layer, and the pressure at the front, middle and rear parts of the device is accurately regulated to redistribute the plantar pressure, and the thumb is corrected and the pressure of the first metatarsophalangeal joint is reduced by a hallux correction block. The present utility model requires placement within a shoe for use and the way in which the toe of the thumb is corrected is different from the present device.
