Intrinsic ankle and foot problems are due to the anatomic injuries of the ankle and foot. The ankle joint is made up of the tibia (main leg bone), fibular (minor leg bone) and the talus the bone between the ankle bumps. Around this joint are multiple ligments, tendons and nerves. In the foot there are many bones. The main ones are the calacaneus or heel bone and navicular as well as smaller bones which make the toes called metacarpals and phalanges. On some bones are bursa (fluid filled sacs).

Ankle sprains:
These ligaments can be treated symptomatically, possibly with braces. If they are partially torn they can be treated with prolotherapy. If fully torn they require surgery.

Retrocalcaneal burisitis:
This fluid filled sac in the back of the foot can be treated with pads, injections are to be avoided. Surgery may be indicated.

Osteocondral defect:
This cartilage injury can be treated with steroid injections but generally require require surgery.

Plantar fascitis:
This foot disorder cause pain at the bottom of the foot which is greatly exacerbated with stepping down the first thing in the morning. It can be treated with exercises, night splints, and rarely steroid injection, although prolotherapy may have a role in its treatment.

Mortons neuroma:
This painful condition between the toes is due to a nerve overgrowth. It can be treated with modified footware, injections or surgery as a last resort.
