Sesamoid Fracture presenting as a BiPartite Sesamoid

Only the abstract is linked here. It shows the dilemma patients are left with when they have bi- or tri-partite sesamoids. Fractures are missed and a needless year of suffering is documented here. We fracture at weak spots in bone. The junction between two fragments of bone like a bipartite sesamoid is such a weak spot. In so many cases, the injury is called a normal variant, and the possibility that there is a possible fracture is dismissed. If you have pain in your big toe joint, and the x-ray shows a bipartite or tripartite sesamoid, discuss the probability that this can be a fracture with your physician.
