Intramembranous ossification involves primitive connective tissue called mesenchyme, while endochondral ossification involves cartilage as a precursor. In most of the fracture, endochondral osteogenesis the most commonly occurring process healing can be done for the long bones which is treated by plaster of paris.

Then what is Endochondral ossification? This ossification occurs in long bones and most of the rest of the bones in the body. An initial hyaline cartilage which continues to grow is involved.  Not only are calcium and phosphorous part of the hard structure of bone tissue but calcium is also stored
