Abstract :
The complete severance of the extensor mechanism in the proximal interphalangeal joint is a difficult injury to treat successfully. In this study, the applicability of finite element analysis for comparing the strength of various types of repair was investigated. Load-deflection tests were performed on severed tendons that were repaired using the standard and Snow method, and the results were compared with the maximum stresses associated with the load-deflection characteristics of the finite element models of these repairs. The results from both set of tests were found to agree qualitatively
