Transverse arch collapse, or collapse of the foot arch, is characterized by a lack of stability of the foot arch, which is characterized by an inability to stand for long periods of time, and a tendency to fatigue fracture, which does not heal on its own. However, it can be relieved or treated by surgery, manipulation assistance, auxiliary devices and so on. 1. Surgery: arch collapse is mainly treated by arch reconstruction, which can effectively alleviate the problem by changing the position of the arch through osteotomy and changing the strength of the ligaments to improve the curvature of the arch. 2. Manipulation assistance: mainly through the soles of the feet to step on tennis balls and other methods, and at the same time assisted by plantar massage to loosen the plantar fascia can alleviate part of the arch collapse. 3. Auxiliary appliances: mainly arch insoles and so on, can make the plantar force change, reduce the burden of ligaments, and is conducive to the walking of the patients with flatfoot disease, but also can relieve the fatigue and pain of patients with foot diseases. In summary, it is recommended that patients go to the hospital for further examination, and at the same time pay attention to their own sports to avoid damage to the foot arch.
