Abstract
Introduction: We compared the results of our computer simulation studies of Z-plasties of different design to those of earlier studies, such as laboratory studies in dogs.
Material and Methods: The contours of single Z-plasties of different designs on flat surfaces were transferred to finite element analytical software (ADINA version 8.7).
Results: The lengthening effect was almost proportional to the size of the Z-plasty, but was always less than what was predicted by geometric calculation. The percent gain in length decreased with the number of Z-plasties.
Conclusion: We used ADINA software analyze the lengthening effects of Z-plasties of different patterns. Our results support those of earlier experiments and should help increase our understanding of Z-plasties of various patterns.
