Stress fractures are relatively common in the sesamoid in athletes or dancers that are required to be on the ball of the foot.  X-rays are often negative and MRIs are needed to evaluate the extent of the injury.  Treatment is often nonweightbearing in a boot to allow the bone to heal.  It can take many months before the bone heals completely and utilization of an orthotic following the healing would further unload the sesamoid.
