Porcine trotters have been reported to be useful models for practicing tendon repair surgery. It is difficult to assess the approach of the trainees to pulleys in the in vitro models e.g. pig trotters as the number and the nature of the pulleys is different to that of humans. In this study, we explored the feasibility of fabricating the human pulley system in pig trotter to help provide a better model reflecting human hand. Twenty fresh porcine trotters were dissected. Thick fibro-osseous tunnel covering the flexor tendons was exposed. A template of human pulley system was made and five annular pulleys carved out in the fibro-osseous tunnel. The fabricated pulleys prevented bow stringing, allowing full excursion of the flexor tendons. Thus, a human annular pulley system can be fabricated in a pig trotter model to make it more effective and efficient training model.
