The knot of Henry is the superficial (i.e. plantar) crossing of the flexor digitorum longus tendon obliquely over the flexor hallucis longus tendon in the midfoot, at the level of the navicular bone. Distally to the knot of Henry there are connections, sometimes multiple, between the two tendons.
Radiographic features
The knot of Henry is best seen on coronal planes 4.
Related pathology
- the knot of Henry is one of the locations of flexor hallucis longus tenosynovitis and could result in an intersection syndrome 2-5
