High Arch, a foot deformity, refers to an abnormally high arch of the foot. Cavus foot can lead to discomfort, pain, and difficulty with movement, affecting daily life and sports activities. This article will introduce the symptoms, causes, diagnosis, and treatment methods of cavus foot.
Symptoms
The main symptoms of high arch foot include:
(1) Foot discomfort: High arch foot causes uneven pressure distribution on the sole, leading to pain, soreness, fatigue and stiffness.
(2) Raised arch: High arch foot increases the height of the arch, causing the sole to be raised and leading to problems such as ill-fitting shoes and unstable walking.
(3) Ankle instability: High arch foot causes excessive ankle extension, reducing the stability of the ankle joint and leading to sports injuries such as sprains.
(4) Hallux valgus: High arch foot causes excessive outward rotation of the big toe, leading to pain and deformation of the joint.
(5) Restricted movement: High arch foot reduces the stability of the foot, leading to problems such as poor mobility and abnormal gait, which can affect sports activities and daily life.
Causes The causes of high arch foot are varied and may include:
(1) Genetic factors: High arch foot may be related to genetic genes, and some people are born with high arch foot.
(2) Neuromuscular diseases: Some neuromuscular diseases such as Charcot-Marie-Tooth disease can lead to high arch foot.
(3) Nervous system damage: Nervous system damage such as brain or spinal cord injury may also cause high arch foot.
(4) Trauma: Foot trauma such as ankle fractures or ankle sprains can also lead to high arch foot.
(5) Other factors: Prolonged wearing of high heels, muscle imbalance, muscle atrophy, and other factors may also cause high arch foot.
Diagnosis The diagnosis of high arch foot is mainly done through the following methods:
(1) Foot examination: The doctor will examine the appearance, shape, and mobility of the foot, observe the arch height, hallux valgus, and other conditions.
(2) X-ray examination: X-ray examination can help the doctor determine the arch height and whether the foot bone structure is normal.
(3) Nervous system examination: The doctor may conduct a nervous system examination to understand the presence of neuromuscular diseases or nervous system damage.
(4) Electromyography examination: Electromyography examination can evaluate the functional status of muscles and the nervous system.
Treatment Methods
The treatment methods for high arch foot mainly include non-surgical treatment and surgical treatment.
(1) Non-surgical treatment: Non-surgical treatment mainly includes the following methods:
Physical therapy: Physical therapy includes methods such as hot and cold compresses, massage, and physiotherapy, which can relieve foot discomfort and pain.
Insoles and shoes: Special insoles and shoes can help adjust the height of the arch and foot stability, reducing foot discomfort and pain.
Exercise therapy: Exercise therapy includes stretching, strengthening, and balance training methods for foot muscles and joints, which can improve foot stability and mobility.
(2) Surgical treatment: Surgical treatment is mainly aimed at patients with severe foot deformities or ineffective non-surgical treatment, including the following methods:
Arch reconstruction surgery: Arch reconstruction surgery reduces the height of the arch by removing part of the bone, tendon, or ligament, achieving the goal of adjusting foot shape and stability.
Soft tissue reconstruction surgery: Soft tissue reconstruction surgery adjusts foot shape and stability by removing part of the soft tissue or transplanting tendons.
In summary, high arch foot is a common foot deformity that can cause foot discomfort, pain, and movement difficulties. The treatment methods for high arch foot include non-surgical and surgical treatments, and choosing the appropriate treatment method can help relieve foot discomfort and pain, improve mobility and quality of life. In addition, measures such as strengthening foot exercises and wearing appropriate shoes can also prevent the occurrence of high arch foot.
