Abstract:
A substantial number of experimental and clinical studies have established that the cornerstones for successful bone-healing are biomechanical stability and biological vitality of the bone, as they both provide an environment in which new bone can be formed. Non-union of long bones is a significant consequence in treating fractures. Many approaches to prevent fracture non-union have been proposed. Depending on the type and location of the non-union, treatment options include various types of bone fixation, with or without supplemental bone graft or other biophysical enhancements.

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.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
