Definition[Bearbeiten]

The ligamentum plantare longum is a long, strong ligament on the plantar side of the foot that connects the calcaneus (heel bone) to the os cuboideum.

Anatomy[Bearbeiten]

The ligamentum plantare longum is the longest ligament of the tarsus. It attaches proximally to the bone in front of the tuber calcanei on the plantar side of the calcaneus. From there, the deep fibres extend distally to the plantar side of the cuboid bone, where it inserts broadly into the bone. Some authors refer to this section of the ligament separately as the calcaneocuboid plantar ligament or the plantar ligament breve. The superficial fibres of the ligament then split and pass over the peroneal sulcus, continuing to the base of the metatarsal ossae II, III, IV and V.


Function[Bearbeiten]

The ligamentum plantare longum provides longitudinal tension to the arch of the foot and strengthens the joint capsule of the lower ankle joint. In addition, it serves as the area of origin of some short foot muscles.
