Abstract:
Osteochondral injuries are an important type of musculoskeletal trauma that can lead to disabling arthritis if not recognized and treated appropriately in the early stages. The anatomic configuration and biomechanical function of a joint are important for understanding its particular pattern of osteochondral injury and the resultant imaging appearance. The imaging of osteochondral fractures and osteochondrosis dissecans (OCD) is reviewed in this article, with particular attention to differentiating surgical and nonsurgical lesions on the basis of their appearance with advanced imaging modalities. Computed tomography (CT) and magnetic resonance imaging (MRI) have improved both the sensitivity and specificity for detection and characterization of osteochondral injuries. MRI is currently the modality of choice for the detection and staging of osteochondral injuries. It has the greatest sensitivity owing to its ability to depict marrow edema and directly assess the fracture clefts of stage 3 lesions, as well as the morphology of articular cartilage. Newer strategies for differentiating stable from unstable osteochondral fragments include MR arthrography and intravenous contrast-enhanced MRI.

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...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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...
