Morphology of the plantar calcaneocuboid ligaments

The plantar calcaneocuboid ligaments have various configurations and are referred to in the literature by different names. The aims of this study were to classify the form and attachments of the plantar calcaneocuboid ligaments and to determine their dimensions to describe their morphology. The plantar aspects of 59 cadaver feet were dissected to expose the associated ligaments. The long and short plantar ligaments showed several structural variations of shape, band number, and attachments. The variations that were seen have led to confusion in the literature, which needs to be resolved. A new nomenclature is suggested based on the observed morphology. These findings agree with previous reports, and data are also presented that describe the shapes of the ligaments.
