Talar Dome Lesions

20th Jun, 2022

What are talar dome lesions?

Talar dome lesions are focal injuries to the talar dome – a part of a significant bone of our foot, the talus. It is also known as an osteochondral lesion of the talus. Usually, there is variable involvement of the subchondral bone of the talus, and cartilage. 

This is typically caused by a traumatic event, such as an ankle sprain. However, it can also be caused as a result of repeated microtrauma to the talus. In some cases, the ankle pain associated with a talar dome lesion can take months to surface following the precipitating event or injury. 

How do I know if I have a talar dome injury?

Some signs and symptoms of a talar dome injury include:

  • Chronic deep pain in the ankle, usually worse with activity (especially during sports), and less with resting
  • Occasional feeling of ankle being “stuck” or “catching” of ankle
  • Feeling that ankle is “locked”
  • Occasional swelling of the ankle – especially when bearing weight, subsiding during rest

How are talar dome lesions diagnosed?

Symptoms for talar dome lesions may be intermittent, and pose a difficulty to diagnose. Many times, this diagnosis is based primarily on a thorough patient history. In most cases, an MRI scan will be a definitive diagnosis of a talar dome lesion.

Treatment options for talar dome lesions?

Usually, we aim to treat talar dome lesions conservatively. This includes:

  • Using a foot orthotics to better align the ankle
  • Use of ankle brace to protect the ankle while easing back into activity
  • Physiotherapy to strengthen the ankle and lower limb
  • Immobilisation in a boot if required, to allow the tissues to rest and heal.

If conservative treatment methods do not adequately resolve and manage your pain, we will be able to refer you to a specialist Foot and Ankle surgeon who can guide you through the next phase of your treatment.
