Dorsal calcaneocuboid ligament
The dorsal calcaneocuboid ligament is the dorsolateral stabilizer of the calcaneocuboid joint and a stabilizer of the midtarsal (Chopart) joint.
Gross anatomy
The dorsal calcaneocuboid ligament can arise as single or multiband-structure lateral of the bifurcate ligament and can merge with the latter, the joint capsule or show some other variations .
Attachments
The origin of the dorsal calcaneocuboid ligament is the distal dorsolateral surface of the anterior process of the calcaneus. The distal insertion is usually at the proximal lateral surface of the cuboid bone about 5-10 mm distal to the calcaneocuboid joint .
Variant anatomy
Common variations include different directions, multiple bundles (e.g. an accessory lateral band in up to 60% of individuals), merging with the calcaneocuboid bundle of the bifurcate ligament as well as a meniscus variant .
Radiographic features
MRI
Due to its small size and many anatomical variations, the dorsal calcaneocuboid ligament is often difficult to picture and might be sometimes best seen on axial images. On sagittal images, it is hard or sometimes not even possible to distinguish it from the calcaneocuboid component of the bifurcate ligament .
