title: A digit replantation model.
abstract: A simple, inexpensive, reproducible, and reliable model for digital replantation is described utilizing the rabbit ear. When compared to the human digit, it provides benefits over previous models. It is of similar tissue type and characteristics. The vessels closely approximate the digit in size and number. Results are easily quantified and the opportunity for a paired control in the same animal exists. Therefore, experimental design and statistical calculations may be simplified. The model can function for either replantation or revascularization with only slight changes in its preparation. Survival rates have been over 90%. In addition, the model provides an excellent forum for the development of technical expertise in the aspiring microvascular surgeon.
