A talar dome lesion is a type of injury that occurs in the cartilage and bone of the talus, which is the bone in the ankle that connects the foot to the leg. The injury can be caused by a single traumatic event, such as an ankle sprain or fracture, or by repetitive stress on the ankle joint.
The symptoms of a talar dome lesion may include pain, swelling, stiffness, and difficulty bearing weight on the affected ankle. In some cases, the ankle may also feel unstable or give way.
Diagnosis of a talar dome lesion may involve a physical exam, imaging tests such as X-rays, CT scans, or MRI, and in some cases, arthroscopy to visualise the inside of the joint.
Treatment for a talar dome lesion may depend on the severity and location of the injury. Conservative treatments may include rest, ice, compression, and elevation (RICE), immobilisation with a cast or brace, physical therapy, and non-steroidal anti-inflammatory drugs (NSAIDs) to relieve pain and inflammation.
In more severe cases, surgery may be necessary to repair or remove the damaged tissue. This may involve procedures such as micro-fracture, drilling, or cartilage transplantation to stimulate the growth of new cartilage and promote healing.
It is important to seek medical attention if you experience persistent ankle pain or notice any unusual symptoms, as untreated talar dome lesions can lead to long-term complications such as chronic pain, arthritis, and joint instability.
