An irritation of the joint at the base of the first, or big, toe, which is usually caused by the toe being bent backward or jammed against the ground. Symptoms include pain and swelling of the toe and difficulty walking. Treatment consists of applying ice, taking pain relievers or anti-inflammatory medications, and elevating the foot.
A hyperextension injury of the first metatarsophalangeal (MTP) joint. Severe hyperextension also injures the plantar sesamoids and flexor tendons. The injury commonly occurs on artificial surfaces such as Astro Turf, where the competitors wear light, flexible-soled shoes that allow MTP hyperextension on the firm surface.
