Plantar calcaneonavicular ligament

Bands of the sole of the foot of the person: 1 (plantar side metatarsal ligaments ( ligaments metatarsalia Plantaria )), 2 soles sided calcaneal-cuboid band ( ligament calcaneocuboideum plantar ), 3 tendon of the peroneus longus, 4 long sole band ( long plantar ligament ), 5 tendon of the musculus peroneus longus , 6 soles sided anklebone midfoot band ( ligament talometatarsale plantar ), 7 tendon of the tibialis anterior , 8 soles sided wedge-navicular band ( ligament cuneonaviculare plantar ), 9 soles sided cube-navicular band ( ligament cuboideonaviculare plantar ), 10 Acetabular ligament ( ligamentum calcaneonaviculare plantare ) , 11 tendon of the musculus tibialis posterior

The ligamentum calcaneonaviculare plantare (Syn. Ligamentum calcaneocentrale plantare , " acetabular ligament ", "flat foot ligament ", English: spring ligament ) is located on the plantar side (sole of the foot ) of the foot and connects the heel bone ( calcaneus ) with the navicular bone (scaphoid bone, Syn. Os tarsi centrale ).

It is conical in shape and runs between the sustentaculum tali and the plantar side of the navicular bone . This area of ​​the foot skeleton bears the head of the talus ( talus ). Its dorsal surface forms part of this joint. The band therefore has a cartilage coating. Since this joint is reminiscent of a pan, the band is also called the “pan band”. The tendon of the tibialis posterior muscle runs over its plantar side .

The plantar calcaneonavicular ligament plays a key role in stabilizing the arch of the foot. If it gives way, the medial part of the longitudinal arch flattens out and flatfoot develops (hence the synonym “flatfoot ligament”).
