Abstract:
Objective To understand the characteristics of subtalar joint motion and to probe a new method in evaluating the subtalar joint. Methods Eight fresh frozen adult shank-foot specimens with calcaneus marked were placed in a Cartesian coordinate system. The motion of the subtalar joint was obtained through matrix translation and Euler equation. Comparatively, the same specimens were underwent CT scan and established three dimensional reconstruction through the radiographic method. Results Both the mechanical and the radiographic methods had no significant difference in reflecting the motion of subtalar joint in coronal and transversal plane. Conclusion To evaluate the motion of subtalar joint with mechanical method was more precise, economic and easier to perform. Although the radiographic method had considerable discrepancy among examiners, as a non-invasion examination, it needs further research.
