Abstract:
Due to poor interdisciplinary communication, many artifical joint designs fail to account for some features that normally allow bones to survive for life. In part, these features concern modeling drifts and remodeling basic multicellular units (BMUs), the microdamage thresholds of bone, its load-grain alignment and shear lock properties, load focusing and defocusing, mechanical usage/strain thresholds for controlling the biological mechanisms, and the regional acceleratory phenomenon. This article reviews briefly some major aspects of these features and suggests how implant design might account for them.

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...
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.

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.
