Summary of background dataResearch on biomechanics of the ankle and foot has demonstrated a complex pattern of load distribution through the ankle joint.ObjectiveInvestigating possible relationship between articular dimensions, angular parameters and overall talar morphology.MethodsTwo linear dimensions, six articular surfaces and three angular parameters were measured from dried human talar bones (left = 60; right = 82). Angular parameters were measured at the neck of the bone (junction of the head and the body). Correlation and co-variation were worked out between the values of surface area parameters and the angular orientations measured from all the samples in context of load transmission across the talus.ResultsThe total trochlear surface area of the talus totaled approximately equal to the sum of areas at the head and the lower surface of the talus. The vertical angle showed a strong correlation with the articulating surface area below the head of the talus in contact with the spring ligament.ConclusionsArticular surface areas as well as the angular orientations of talar components vary with the magnitude of stress subjected to the bone. The inter-relationship between articular and angular parameters within the talus demonstrates strong correlation for certain parameters.
