Hallux valgus correcting shoes

Abstract

Hallux valgus malformation refers to deflection and transposition of hallux towards outside from a first metatarsophalangeal joint. Hallux valgus is a complex dissection malformation, and extremely challenged in terms of treatment. Each of the hallux valgus correcting shoes consists of a shoe sole and an upper; an opening is arranged on the upper, and the opening can make that only a part of upper at the back edge of the rest upper at the inside of the upper is connected with the other part of the upper, the narrowest place at the connecting part of the back edge is used as a boundary, and the upper is defined into an inside upper and an outside upper; an extending rib capable of crossing through a joint between thumb and index finger is arranged on the outside upper; the rib is connected with the sole; the inside upper at least includes more than 4 square centimeters of faces located thumb phalanx and sole joint inside and capable of contacting with foot part.

Description

Technical field [0001] The invention relates to the field of foot health products, in particular to a shoe that helps correct and prevent hallux valgus deformity of the foot. Background technique [0002] Hallux valgus deformity refers to the deflection and displacement of the hallux toe at the first metatarsophalangeal joint. Hallux valgus is a complex anatomical deformity, and it is extremely challenging to treat. Bunion refers to the obvious medial protrusion that appears in hallux valgus deformity, but in general, these two terms can be used interchangeably. Hallux valgus is the most common disease involving the hallux. It is more common in middle-aged and elderly women. It most often occurs in people who have a genetic predisposition and wear inappropriate shoes for a long time. Inappropriate shoes can put abnormal pressure on the hallux. Hallux stiffness generally manifests as the hallux deflection to the outside at the first metatarsophalangeal joint, and obvious osteoph...

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
