Correcting shoes for preventing hallux valgus

Abstract

Hallux valgus malformation means that the hallux deflects and displaces towards the outside at the first metatarsophalangeal joint. Hallux valgus is complicated anatomical malformation, and the treatment is very challenging. The invention provides a preventive corrector worn in the form of shoes, namely, the shoes capable of conveniently preventing and correcting hallux valgus. The correcting shoes for preventing hallux valgus are composed of shoe soles and shoe vamps, wherein each shoe vamp contains a correcting plate, the correcting plate is positioned in the gap between the hallex and the index toe, and is connected with the shoe sole, the correcting plate contacts the outer side of the part of the first interphalangeal joint or the distal phalanx of the hallex, and applies the inward force towards the part, the shoe vamp contacts the inner side of the first metatarsophalangeal joint part of the foot, and applies the outward force towards the inner side of the part, and the shoe vamp contacts the outer side of the part of the fifth metatarsophalangeal joint or the fifth metatarsal bone of the foot, and applies the inward force towards the part.

Description

technical field [0001] The invention relates to the field of foot health care products, in particular to a hallux valgus prevention corrective shoe for correcting and preventing hallux valgus deformity of the foot. Background technique [0002] Hallux valgus is a lateral deviation of the hallux at the first metatarsophalangeal joint. Hallux valgus is a complex anatomical deformity and can be extremely challenging to treat. A bunion refers to the prominent medial protrusion that occurs in hallux valgus, but the two terms are generally used interchangeably. Hallux valgus is the most common lesion affecting the hallux. It is more common in middle-aged and older women. It occurs most often in people who have a genetic predisposition plus prolonged wearing of ill-fitting shoes that put abnormal pressure on the hallux. Hallux stiffness generally manifests as a lateral deviation of the hallux at the first metatarsophalangeal joint, and obvious osteophytes appear on the inner side...

AI Technical Summary

Problems solved by technology

3. Severe stage of hallux valgus: hallux valgus 20-40 degrees, overlapping toes, collapsed transverse arch, corns, pads, flat feet, heel pain, difficulty balancing the force on both feet, seriously affecting standing and walking

4. Hallux deformity stage: hallux valgus above 40 degrees, toes end of mission, hallux is seriously overlapped, toes are not stressed, arch collapses, it is difficult to walk, the sole of the foot bears part of the pressure of the toes directly, there are calluses on the soles, both feet Severely wrong negative force, it is difficult for all joints to coordinate and operate, resulting in changes in the negative force line of the human body, causing knee joint inflammation, back pain, etc.

Adductor hallux tenotomy and first metatarsal osteotomy are also commonly used methods; correction refers to wearing corrective devices. The current hallux valgus correctors are all worn on the feet, and the correction is achieved through the elastic force of the parts on the device Purpose, but due to the large daily force on the human foot, the external force that causes hallux valgus is also very large. For example, some high-heeled shoes cause hallux valgus because the body weight is concentrated on the forefoot and the shoes are worn for a long time. However, the current orthotics cannot provide such a large correction force, and it is not conducive to the patient's movement during the correction process, and even if the current correction device uses such a large correction force, the patient cannot bear the pain caused by the continuous tightening of the foot
