Arch-shaped versus flat arthrodesis of the ankle joint: strength measurements using synthetic cancellous bone
(2002) In Proceedings of the Institution of Mechanical Engineers. Part H: Journal of Engineering in Medicine 216(H1). p.43-49- Abstract
- The aim Of this Study was to see if preservation of the arch shape of the ankle at arthrodesis contributes to stability. The ankle joint was simulated by paired blocks of a synthetic material corresponding to rheumatoid cancellous bone with low stiffness and strength. Flat end constructs with and without subchondral bone were compared with arch-shape constructs with and without subchondral bone. The pairs were fixed with two screws simulating an arthrodesis. These constructs were then tested to failure in four-point bending and torque. In four-point bending the subchondral bone increased the strength, regardless of shape. Stiffness was higher in the arch-shaped specimens but was not influenced b the subchondral bone. In torque, both... (More)

Stiffness was increased by arch-shape but not subchondral bone. The results imply that the arch-shape and subchondral bone should be preserved when performing an ankle arthrodesis, especially in weak rheumatoid bone. (Less)
