Pathological dislocation of the second toe is a definite deformity that has not been dealt with in the medical literature of the world. There has been one case reported previously. This deformity is not a rare condition, and it is becoming more common. The etiology has been explained on an anatomical, kinesiological, and neurological basis by showing that the line of force of the contracting muscles is altered by chronic hyperextension of the proximal phalanx of the second toe. The musculature of the second toe is different from that of the other toes. This has proved to be a definite etiological factor in the production of the dislocation.
