[1] Open reduction and internal fixation surgery is typically used to repair an osteochondral fracture. For a AO Type B1 [2] [circular reference] partial articular fracture of the lateral condyle, interfragmentary lag screws are used to secure the bone back together. Supplementation of buttress screws or a buttress plate is used if the fracture ...
These cellular units will then develop into skeletal and other tissues, such as cartilage, tendon, ligament and muscle tissue. [ citation needed ] Osteoprogenitor cell condensations can aggregate, dissipate or condense depending on the signals present, however these still remain largely unknown.
Some examples of secondary cartilaginous joints in human anatomy would be the manubriosternal joint (between the manubrium and the body of the sternum), intervertebral discs, and the pubic symphysis. Articulating bones at a symphysis are covered with hyaline cartilage and have a thick, fairly compressible pad of fibrocartilage between them.
In long bones, the secondary centers appear in the epiphyses. [2] At the end of the formation of the secondary ossification center, the only two areas where the cartilage remains is at the articular cartilage covering the epiphysis and at the epiphyseal plate between the epiphysis and diaphysis.

Medical condition Osteochondritis dissecans A large flap lesion in the femur head typical of late stage Osteochondritis dissecans. In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage.

[1] Runx2 is another important genetic component of Chondroblast formation. It has been found that expressing this gene will result in the suppression of the differentiation of chondroblasts. Expression of this gene will also prompt already formed cartilage to undergo endochondral ossification which will prompt the cartilage to form bone.
Endochondral ossification is the process by which most vertebrate axial skeletons form into hardened bones from cartilage. This process begins with a cartilage anlage where chondrocyte cells will congregate and start their maturation process. Once the chondrocytes have fully matured at the desired rate, the cartilage tissue will harden into ...
Hereditary multiple osteochondromas (HMO), also known as hereditary multiple exostoses, is a disorder characterized by the development of multiple benign osteocartilaginous masses in relation to the ends of long bones of the lower limbs such as the femurs and tibias and of the upper limbs such as the humeri and forearm bones.
