Incapacitation of the posterior tibia tendons
Posterior tibial tendon disability is mainly caused by inflammation or tearing of the posterior tibial tendon, which is a very important muscle in the leg, which connects the calf muscle and the scaphoid bone on the inside of the foot, responsible for maintaining and supporting the arch of the foot when walking, such as the posterior tibia muscle problems have the opportunity to maintain the stability and support of the arch of the foot, so the arch collapse is made.
Sudden trauma such as sprains or repetitive high-intensity sports such as playing soccer can cause tendons to tear and become inflamed, forming a posterior tibia tendon incapacitation, losing the ability to support the arch, and gradually collapsing the arch. The symptoms of posterior tibial tendon dysfunction are very similar to those of the general flat foot, the patient will cause the heel to turn outward due to the collapse of the arch, and the collapse of the arch will also cause the knee joints of the feet to be close to each other, forming an "X-shaped foot".
Maintaining the above position for a long time will add to the wear and tear of the knee and ankle joints, forming joint pain. Unlike the general flat foot, the incapacitation of the posterior tibial tendon is caused by tendon inflammation, so the position of the posterior tibia muscle in the ankle may be more swollen and painful.
The treatment of tendon dysfunction in the posterior tibial tendon begins with more rest, reducing strenuous exercise, and allowing the tendons to have time to recover. In order to reduce foot pressure and avoid tendons from being strained due to the collapse of the arch, patients should wear insoles for support and give arch support, which is also conducive to reducing the time required for treatment. In addition, patients should also pay attention to whether their shoes can give sufficient support to the foot, and the appropriate shoes should have a hard heel embryo and a stable shaped midsole to support the foot, so as to avoid varus of the ankle and strain tendons due to the collapse of the arch when walking. If the shoe has been excessively worn, it should be replaced immediately. On the other hand, patients can soak their feet in hot water when they are swollen, which promotes blood circulation, reduces swelling and promotes tendon rehabilitation.
