ABSTRACT

SUMMARY:

The tarsal tunnel (TT) is an osteofibrous tunnel that separates into proximal and distal tarsal tunnels. The most common nerve entrapment which involved tarsal tunnel was tarsal tunnel syndrome (TTS) which divided into proximal TTS and distal TTS because they had different compression areas and symptoms. We were interested in distal TT because this structure had limited studies. Therefore, we studied anatomical landmarks of locations and boundary of distal TT. We studied forty legs from fresh frozen cadavers and used two reference lines Malleolar-calcaneal (MC) and navicular-calcaneal (NC) axes. The locations of the distal tarsal tunnel were defined by 10 located points and were recorded in X-coordinate and Y-coordinate. The lengths of boundary of the tarsal tunnel were measured from one point to the other. These results were reported as mean±SD. We found that the distal TT located deep to abductor hallucis (AbH) muscle. Medial wall of distal TT had two layers such as deep fascia of AbH muscle and deep thin layer. It showed the trapezoidal shape and was divided into two tunnels by the septum. The information of the location and boundary of the distal TT could improve knowledge and understanding of clinicians and anatomists. Additionally, this information could help surgeons improve their treatments, especially tarsal tunnel release.
RESUMEN
RESUMEN El túnel tarsiano (TT) es un túnel osteofibroso que se divide en túneles tarsianos proximal y distal. El atrapamiento nervioso más común del túnel tarsiano es el síndrome del túnel tarsiano (TTS), el cual se divide en TTS proximal y TTS distal debido a diferentes áreas de compresión. En este trabajo se estudiaron los puntos de referencia anatómicos de las ubicaciones y los límites del TT distal. Estudiamos cuarenta piezas de cadáveres frescos congelados y utilizamos dos líneas de referencia ejes maleolar-calcáneo (MC) y navicular-calcáneo (NC). Las ubicaciones del túnel tarsiano distal se definieron en 10 puntos y se registraron en coordenadas X e Y. Las longitudes de los límites del túnel tarsiano se midieron desde un punto a otro. Estos resultados se informaron como media ±DE. Encontramos que el TT distal se ubicaba profundo al músculo abductor del hállux (AbH). La pared medial del TT distal tenía dos capas, la fascia profunda del músculo AbH y una capa delgada profunda. Se observó la forma trapezoidal del túnel la que se encontraba dividida por el tabique en dos túneles. La información de la ubicación y el límite del TT distal podría mejorar el conocimiento de los médicos y anatomistas. Además, esta información podría ayudar a los cirujanos durante los tratamientos, especialmente la liberación del túnel tarsiano.
