Background:
Ossification of the ankle syndesmosis can occur following trauma to the ankle. Little is known about the treatment of syndesmosis ossification.
Case Description:
A 49-year-old man was referred to the orthopaedic outpatients' clinic by his GP with swelling on the lateral side of his right ankle. A few months earlier the patient had sustained an injury to his ankle while playing football, for which he had not been treated. X-ray examination revealed ossification of the ankle syndesmosis with an old posterior tibial fracture.
Conclusion:
The patient had ossification of the right ankle syndesmosis. This type of ossification has a benign natural course and a policy of wait and see, plus pain relief, is usually sufficient. Surgical removal of the ossification should only be considered in active sportsmen and sportswomen with persistent symptoms that do not respond to conservative treatment.

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...

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
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...
