title: Extensor mechanism of the fingers. II. Tensile properties of components.
abstract: Seven fresh human finger specimens have been studied to determine the differences in structural stiffness between different components of the extensor assembly. Differences were found to be significant, ranging from an average of 275 N/mm for the proximal and distal segments of the central band to an average of 40 N/mm for the central-to-lateral intercrossing fascicles. The terminal tendon of the lateral band was shown to be as stiff as the middle segment of the central band.
