Foot

What It Is

The simplest definition of this condition is a sprain of the main joint of the big toe, often called turf toe. It happens when the toe is forcibly bent upwards into hyperextension, for example when pushing off into a sprint and having the toe stuck flat on the ground (American Academy of Orthopaedic Surgeons, n.d.).

Sprains of the big toe joint became especially common in American football players after artificial turf became more common on playing fields, which is where the name turf toe came from. Artificial turf tends to be harder and less shock-absorbent than grass and doesn't give as much when forces are placed on it. Shoes designed for artificial surfaces are also softer and more flexible, which gives more agility but much less stability in the front of the foot (American Academy of Orthopaedic Surgeons, n.d.). Even though it is often linked to American football, turf toe can occur in many sports and activities, including rugby and football (soccer) (American Academy of Orthopaedic Surgeons, n.d.; Najefi, Jeyaseelan and Welck, 2018).

First Metatarsophalangeal (MTP) Joint Sprain Anatomy

Two joints make up the big toe. The larger of the two is the metatarsophalangeal (MTP) joint, which is where the first long bone of the foot (metatarsal) meets the first bone of the toe (phalanx). In turf toe, the MTP joint is the one that gets injured (American Academy of Orthopaedic Surgeons, n.d.).

The MTP joint is held in place by a group of structures under and around it, called the plantar complex. These include a thick band of tissue under the joint (the plantar plate), the ligaments on each side of the toe, a tendon that helps the toe push off, and two small bones called the sesamoids. Turf toe can range from stretching of these tissues (grade 1), to a partial tear (grade 2), to a complete tear (grade 3) (American Academy of Orthopaedic Surgeons, n.d.).

How long it takes to recover depends on the grade. A grade 1 injury usually lets you return to sport as you can tolerate it, with little or no time lost (Najefi, Jeyaseelan and Welck, 2018). Most athletes with a grade 2 injury need 3 to 14 days of rest before returning to play (American Academy of Orthopaedic Surgeons, n.d.). A grade 3 injury may need 8 weeks or longer, and it can take up to six months for the symptoms to settle completely (Najefi, Jeyaseelan and Welck, 2018).
