Osteoarthritis: the peripheral joints
Abstract:
UNDERSTANDING OF OSTEOARTHRITIS HAS INCREASED: the simplistic "wear and tear" concept no longer holds and this has positive clinical implications. A parallel development has taken place in treatment techniques: there is increasing expertise in the use of physical measures and in new orthopedic reconstructive surgical approaches to multiple joints. This gives the physician alternative approaches to the patient with painful and disabling osteoarthritis. The timing of these treatment options and some considerations which lead to orthopedic referral are considered in this general discussion.

Peripheral Artery Disease I: Introduction
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

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.
