Open reduction and fusion of the calcaneocuboid joint is occasionally required.
2.
Forcible attempts at correcting the heel varus by abducting the forefoot while applying counter pressure at the calcaneocuboid joint prevents the calcaneus from abducting and therefore everting.
3.
Generally, the surgical procedure involves making an anterolateral incision, stripping the ligaments from both calcaneocuboid joint, and the medial malleolus lies just above and behind the navicular bone.
4.
The "'posterior surface "'is smooth, triangular, and concavo-convex, for articulation with the anterior surface of the calcaneus ( the calcaneocuboid joint ); its infero-medial angle projects backward as a process which underlies and supports the anterior end of the calcaneus.
5.
"Mesotherium "'s ankle joint was made up of a " ball-and-socket " arrangement between the astralagus and the navicular, as well as a sliding articulation of the calcaneocuboid joint, which would cause extension-flexion in the ankle, as well as supination-pronation of the foot.
