medial ligament of ankle joint

[TA]
compound ligament consisting of four component ligaments that pass downward from the medial malleolus of the tibia to the tarsal bones: 1) tibionavicular ligament (pars tibionavicularis [NA]), 2) tibiocalcaneal ligament (pars tibiocalcanea [NA]), 3) anterior tibiotalar ligament (pars tibiotalaris anterior [NA]), and 4) posterior tibiotalar ligament (pars tibiotalaris posterior [NA]).

Synonym(s): ligamentum deltoideum.

deltoid ligament

The strong triangular ligament, on the inner side of the ankle, which helps to bind the foot to the leg. A torn deltoid ligament may leave an unstable ankle that ‘goes over’ easily.

deltoid ligament

medial collateral ligament of the ankle (see Table 1)

Anatomical featureLocation
Long plantar ligament (LPL)Plantar aspect of calcaneum (just anterior to calcaneal tuberosity); insert
• Deep portion: into plantar aspect of cuboid
• Superficial portion: base of 2-5 metatarsals
Short plantar ligament (SPL) (plantar calcaneocuboid ligament)Anterior tubercle of calcaneum; inserts into adjacent plantar surface of cuboid
Spring ligament (SL) (plantar calcaneonavicular ligament)Anterior margin of sustentaculum tali; inserts into plantar aspect of navicular
Interosseous ligament (IL) (talocalcaneal ligament)Within sinus tarsi; connects non-articular parts of subtalar joint
Deltoid ligament (DL) (medial collateral ankle ligament)Fans out from anterior, medial and posterior aspects of medial malleolus; insets into navicular, spring ligament, sustentaculum tali and adjacent talus
Plantar aponeurosis (PA) (deep plantar fascia)From calcaneal tuberosity to midfoot, where it splits into five bands
Each band attaches distally to plantar aspect of transverse intermetatarsal ligament (overlying and linking plantar aspects of all metatarsophalangeal joints) and plantar surface of respective proximal phalanx

Baird and Jackson (12) studied a series of 24 SE4 and PE3 and four equivalents, where disruption of the deltoid ligament was diagnosed clinically by medial tenderness over the ligament and by radiographic confirmation of a widened mortise.
In both cases, an effort was made to repair the deltoid ligament.
Excision of the lateral malleolus articular surface did not reduce rotational stability but division of the deltoid ligament caused a two-fold increase in rotational instability.
However, once the deltoid ligament was sectioned, all ankles showed a significant decrease in tibio-talar contact area.
Anterior collicular fractures may occur as an isolated injury or in association with rupture of the deep deltoid ligament and account for 15% to 20% of medial malleolar fractures.
