Abstract:
We describe a case of a large intra-articular ossifying mass of the ankle joint in a 12-year-old boy who sustained a severe ankle twisting injury at 6 years of age. The mass is presumed to be the result of secondary synovial osteochondromatosis originated from a fractured osteochondral fragment of the medial tubercle of the posterior process of the talus. The mass could be differentiated from os trigonum syndrome, Trevor disease and primary synovial osteochondromatosis based on its location, size and radiologic and histological features.

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...

Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...
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...
