摘要
Strains in the extensor mechanism of the finger were measured in a cadaver model using Hall-effect transducers. Several components of the mechanism were evaluated at different joint positions, with different intrinsic and extrinsic tendon loading conditions, and after creating a boutonniere deformity. Landsmeer's theory that predictable and obligatory interactions occur within the extensor mechanism during finger movement is strongly supported by our results. The concept of the Bunnell intrinsic-lightness lest was confirmed. Results were consistent with clinical observations and current theories on the pathomechanics of claw and boutonniere deformities. Based on our experimental findings, we conclude that strain analysis is an effective method of evaluation of the extensor mechanism with potential for in vivo surgical applications.
