What It Is

The extensor tendons run along the top of the foot and help to lift (straighten) the toes and the foot. The most common injury to these tendons is extensor tendinopathy (sometimes called tendinitis), where one or more of the tendons becomes painful and swollen because it has been overworked (NHS Lanarkshire, 2023). Typical symptoms are an aching pain on the top of the foot or the front of the ankle that comes on gradually, swelling on the top of the foot, and pain that increases with activity and may be made worse by shoes, especially tight ones (NHS Lanarkshire, 2023).

Less commonly, a tendon on the top of the foot can be torn. This can happen with a deep cut, for example from a sharp object dropped on the foot (Kim et al., 2021), or as a sudden injury during an accident or activity (NHS, 2023).

Extensor Digitorum Tendon Injury Anatomy

The extensor muscles are on the front of the lower leg, and their tendons run down over the front of the ankle and along the top of the foot (NHS Lanarkshire, 2023). The main tendons are:

  • Tibialis anterior: the main muscle that lifts the ankle (NHS Lanarkshire, 2023).
  • Extensor digitorum longus: this lifts the four smaller toes.
  • Extensor hallucis longus: this lies between the other two muscles and lifts the big toe (Kim et al., 2021).

These tendons help to lift the foot and toes so they clear the ground when you walk (NHS Lanarkshire, 2023).
