Bandverletzungen am Innenknöchel

Deltoid ligament injuries involve the deltoid ligament that forms the medial part of the ankle joint. It attaches the medial malleolus to multiple tarsal bones.

Pathology

Mechanism of injury

It occurs due to eversion and/or pronation injury, or can be associated with lateral ankle fractures.

The deltoid ligament is usually avulsed from its tibial attachment, causing lateral talar shift with increased medial clear space (>4 mm).

Types

Types of injuries to anterior part of the deltoid ligament:

  • type 1: proximal tear or avulsion of the ligament
  • type 2: intermediate tear of the ligament
  • type 3: distal tear or avulsion of the deltoid and spring ligaments

Treatment and prognosis

Open reduction internal fixation is the treatment of choice.
