Abstract:
Ball-and-socket deformity of the ankle joint is a rare entity that is usually associated with inequality of leg length, fibular hypoplasia, coalition of the tarsal bones, and ray deficiency. This deformity was encountered in a nine-year-old girl with a short right limb, cavovarus foot, partial fusion of the 4th and 5th metatarsals, and talocalcaneonavicular coalition. No surgical intervention was necessary; the patient was recommended to wear a high-heeled shoe of 2.5 cm thickness to compensate for the difference in the leg length.

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.

Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
