RESUMEN
The purpose of the present study was to describe the morphological aspects of the antero-medial side of the ankle region, that was similar to the anatomical snuffbox on the lateral side of the dorsum of the wrist. Dissection of this region was performed on twenty-two adult human cadaveric specimens of the ankles in both sexes. This region appeared as triangular skin depression on full extension of the big toe and inversion of the foot. Its base was formed by the anteroinferior end of the medial malleolus and bounded by the tendons of tibial muscles; tibialis anterior anterosuperiorly and tibialis posterior postero-inferiorly. The roof was formed by the skin and fasciae. Great saphenous vein and saphenous nerve were found in the superficial fascia, crossing the triangle medial and superficial to tibialis anterior. The floor was formed by the deltoid ligament of the ankle joint. This ligament appeared strong. However, the most thickened band was that attached to the sustentaculum tali. The presented anatomy provides a basis for a relatively safe area for a needle puncture or surgical approach of the ankle joint
