Cadaveric anatomical study of anterior and posterior ankle arthroscopic portals in ankle plantarflexion and dorsiflexion positions:

摘要

Category:ArthroscopyIntroduction/Purpose:Arthroscopy of the foot and ankle, which is minimally invasive technique, is able to be used in the treatment of various foot and ankle pathologies. However, complications after anterior or posterior ankle arthroscopies have been described, such as neurovascular structures injury around portals. On the other hand, plantarflexion and dorsiflexion of the ankle joint leads movement of the neurovascular structures. However, there were a few reports about the change of the distance between each portal and nerves or vessels during motion of the ankle. The purpose of this study was to evaluate the distance between each anterior or posterior portal and neurovascular structures, to elucidate the change of the distance between each portal and neurovascular structures in ankle plantarflexion and dorsiflexion positions.Methods:Six feet of 6 fresh cadavers (3 males and 3 females) were enrolled in this study. The mean age was 81.5 years. Standard antero-lateral (AL), antero-medi...
