The short plantar ligament or plantar calcaneocuboid ligament is a stabilizer of the calcaneocuboid joint, which forms the lateral part of the midtarsal (Chopart) joint.

Gross anatomy
The short plantar ligament is cone-shaped, consisting of a deeper and superficial part. It connects the inferior calcaneus to the plantar aspect of the cuboid bone and runs slightly medial and deep to the long plantar ligament 1,2.
Attachments
The proximal origin of the short plantar ligament arises from the distal inferomedial aspect of the anterior tubercle of the calcaneus anterior to the origin of the long plantar ligament.
The distal insertion is located on the plantar aspect of the cuboid bone, proximal to the peroneus longus tunnel 1,2.
Radiographic features
MRI
The short plantar ligament is characterized by a striated appearance and best assessed on sagittal and axial images 1,2.
