Abstract:
This article discusses the introductory physiology of bone healing with respect to arthrodesis. The joints of the foot and ankle can suffer many trials and tribulations in an otherwise normal life, and must adapt to instances such as fractures, dislocations, and congenital problems. When adaptation leads to a malformation in the unit structure, surgical intervention is required to restore the foot and ankle complex to a working device. Primary indications for regarding any joint fusion in the human body include deformity, instability, and pain. An overview of the indications for performing joint fusions at the foot and ankle is presented.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
