deltoid ligament injury
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.
