What movement occurs at the Talonavicular joint?
The talonavicular joint is the most anterior part of a more complex joint, the talocalcaneonavicular (TCN) joint (Fig. 14.17). Like the subtalar joint, it is a triplanar joint producing simultaneous movements across longitudinal, vertical and horizontal axis (supination/pronation, inversion/eversion).

What is Talonavicular dislocation?
A talonavicular dislocation is a rare luxation of the foot, often after a high-velocity trauma. Up to 80% of the talonavicular dislocation is medial, 17% lateral. The lateral dislocation can be reduced under sedation with flexion in the knee, longitudinal traction on the foot and lateral pressure on the talus.
Is the Talonavicular joint part of the foot or ankle?
The talonavicular joint (TNJ) is part of the transverse tarsal joint in the foot, which includes the calcaneocuboid joint. These joints act synchronously with the subtalar and ankle joints when walking.
Is the Talonavicular joint a ball and socket?
Articular surfaces As the name suggests, the talocalcaneonavicular joint is a synovial ball and socket joint formed between three tarsal bones (talus, calcaneus and navicular) and the adjacent ligamentous structures. There are five articular facets on the talus that participate in the formation of this joint.
At what joint does eversion and inversion occur?
Structure and Function The ankle joint is important during ambulation because it adapts to the surface on which one walks. The movements that occur at the ankle joint are plantarflexion, dorsiflexion, inversion, and eversion. The muscles of the leg divide into anterior, posterior, and lateral compartments.
Can you walk with a fractured talus bone?
What is the long-term prognosis for a talus fracture? With or without surgery, your foot will be in a cast or splint. You won’t be able to put any weight on it or walk on it. Depending on the complexity of your injury, you may have to wear the cast for eight to 12 weeks or more.
What causes talus fracture?
Cause. Most talus fractures are the result of high-energy trauma such as a car collision or a fall from height. Injuries from sports, particularly snowboarding, are another, though less common, cause of talus injuries.
What is a Talonavicular joint?
The talonavicular joint is the universal joint of the foot, allowing rotation, sideways movement and up / down motion at the midfoot. It is involved in the flexibility and movements of the foot particularly on uneven ground, whereas most of the up / down movements occur at the ankle above.
How long does a dislocated foot take to heal?
Toe fracture or dislocation
| Healing: | This injury normally takes 6 weeks to heal. |
|---|---|
| Pain and Swelling: | The swelling is often worse at the end of the day and elevating your foot will help. Take pain killers as prescribed. Mild pain and swelling can continue for 3-6 months. |
How is Talonavicular joint treated?
Medications which can be used to treat talonavicular arthritis include analgesics such as paracetamol, as well as nonsteroidal anti-inflammatory drugs such as ibuprofen. When non operative treatment fails to work, surgery may be considered appropriate to treat talonavicular arthritis.
Is the Talonavicular joint synovial?
Articular surfaces As the name suggests, the talocalcaneonavicular joint is a synovial ball and socket joint formed between three tarsal bones (talus, calcaneus and navicular) and the adjacent ligamentous structures.
