title: Biomechanics and computer simulation of the Z-plasty.
abstract: BACKGROUND
  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.
  
  
  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.
  
  
  CONCLUSIONS
  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.
