The mechanism of this specific trauma is still not well to understood, due to the strength needed in different ways and directions for its occurrence, in a complex way. Few cases of an isolated dislocation of the navicular reported in medical literature, and there is little information about complications how the patients evolve after years of postoperative. The authors present a case of a woman, 39-years-old, who suffered a complete dislocation of the talus-navicular of her left foot, due to a fall. After initial k-wire fixation, the patient presented herself 6 weeks later with chondrolysis of the tarsus articulations and submitted to selective arthrodesis of talus navicular and cuneiform medial-talus-navicular (TN + CTN). Having passed 13 years of post-surgery, the patient presents a good clinical evolution and articulation functionality. It concluded that the isolated navicular dislocation, even though promptly and adequately reduced and stabilized, may develop complications, such as chondrolysis, and the correct handling by selective arthrodesis enables a satisfactory functional and clinical outcome.
