What is a FDS tendon?
Flexor digitorum superficialis (FDS) tendons They are powered by a common muscle belly shared by all the fingers, which divides into 4 tendons. They travel down the forearm and within the carpal tunnel. Just like the flexor digitorum profundus tendons, these tendons glide in sheaths along the fingers and the hand.
What causes extensor digitorum longus pain?
Most commonly it is the extensor tendon to the big toe (EHL) that is affected. In other instances the extensor tendons to the lesser toes (EDL) is affected.
