Foot

What It Is

Turf toe is a sprain of the main joint of the big toe, the metatarsophalangeal (MTP) joint. It happens when the big toe is forcibly bent upwards beyond its normal range (hyperextended), for example when pushing off into a sprint and the toe gets stuck flat on the ground (AAOS, n.d.a). It causes pain, swelling and stiffness in the big toe joint. Turf toe injuries that are dealt with early usually heal fairly well, but some people are left with lasting pain or stiffness (AAOS, n.d.a), and repeated injuries to the big toe can contribute to arthritis of the joint (hallux rigidus) over time (AAOS, n.d.b).

Causes of Turf Toe

Turf toe can occur in any sport or activity in which the front of the foot is fixed on the ground, the heel is raised, and a force pushes the big toe up into hyperextension (AAOS, n.d.a).

It is common in American football, and it became especially common after artificial turf became widespread, which is how it got its name. Artificial surfaces are harder and less shock-absorbing than grass, and the flexible shoes designed for them give less support to the front of the foot (AAOS, n.d.a). It also occurs in a wide range of other sports and activities.

Turf toe injuries are graded from 1 to 3, mild to severe (AAOS, n.d.a)

  • Grade 1: the tissues under the joint are stretched, causing pinpoint tenderness and slight swelling.
  • Grade 2: the tissues are partly torn, causing more widespread tenderness, moderate swelling and bruising. Moving the toe is limited and painful.
  • Grade 3: the tissues are completely torn, causing severe tenderness, swelling and bruising. It is difficult and painful to move the big toe.

How is Turf Toe Diagnosed?

Your doctor or I will first assess the toe. This includes asking about your general health, your sport and exactly how the injury happened (AAOS, n.d.a). During the physical examination, they will check for swelling and bruising, press around the toe, and gently move the big toe up, down and side to side to check its range of movement and look for signs of a ligament tear. They may compare it with your other big toe (AAOS, n.d.a).

A doctor may also arrange an X-ray to check for small fractures or problems with the small sesamoid bones, or an MRI scan to look at the soft tissues in more severe injuries (AAOS, n.d.a).

Turf Toe Anatomy

The big toe is known as the hallux. The joint at the base of the big toe is the metatarsophalangeal (MTP) joint, where the first long bone of the foot (the metatarsal) meets the first bone of the toe (AAOS, n.d.a). The joint is held in place by a group of structures together called the plantar complex (AAOS, n.d.a):

  • Plantar plate: a thick, fibrous tissue under the joint that stops the big toe bending too far upwards.
  • Collateral ligaments: ligaments on each side of the big toe that stop it moving too far from side to side.
  • Flexor hallucis brevis: a muscle whose tendon runs under the first metatarsal and gives strength and stability to the big toe when pushing off.
  • Sesamoids: two small bones within the tendon that help it move smoothly and help bear the weight placed on the front of the foot.

Turf toe is an injury to any of the soft tissues of the plantar complex, ranging from stretching to partial tearing and, in the most severe cases, dislocation of the joint (AAOS, n.d.a).
