What is the main complication in fractures in the neck of the talus?

What is the main complication in fractures in the neck of the talus?

Classic complications following open fixation of talar neck fractures include osteonecrosis or avascular necrosis (AVN), posttraumatic arthritis, and malunion.[2]

How long does a talar neck fracture take to heal?

Most talar neck fractures are displaced and require surgery to reposition the bones back to their original position. Recovery requires a prolonged period (6-12 weeks) of non-weight bearing.

What is a talar neck fracture?

Talar neck fractures extend through the thinnest cross-sectional portion of the talus, just proximal to the talar head. They represent one of the most common types of talus fracture (~30-50%), along with chip and avulsion fractures of the talus (~40-49%).

Does a fractured talus require surgery?

Because the talus is important for ankle movement, a fracture often results in substantial loss of motion and function. A talus fracture that does not heal properly can lead to complications, including a limp, arthritis, and chronic pain. For this reason, most talus fractures require surgery.

Where is the talar dome located?

The talar dome is the upper part of the foot bone (talus) which joins with the leg bones and forms the lower half of the ankle joint. The dome is made of bone (osteo-) and is covered with a layer of cartilage (-chondral).

What is a talar shift?

Spiral fracture through the distal fibula. Fracture line through the ankle joint in keeping with a Weber B, with slight lateral talar shift (widening of medial clear space). Well-corticated ossicle distal to the medial malleolus may be post-traumatic or congenital (i.e. an accessory ossicle).

Can you walk on a talus fracture?

You should be able to walk on it, but not without pain. Displaced. The pain, swelling, and tenderness are greater. You may not be able to put weight on the injured ankle.

How do you treat a talar dome fracture?

Nonsurgical Treatment Approaches

1. Immobilization. Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus.
2. Oral medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be helpful in reducing the pain and inflammation.
3. Physical therapy.
4. Ankle brace.

How do you get a talar dome fracture?

A talar dome fracture can be caused by: An inversion ankle injury (the foot rolls inwards accidentally), about 2%-6% of acute ankle sprains are associated with a talar dome fracture. A combined inversion injury with a compression element of the joint into the ground.

What does the talar tilt test for?

Purpose: To test for injury to the lateral ligaments of the ankle. Test Position: Supine or sitting. Performing the Test: The examiner stabilizes the distal leg in a neutral position and inverts the ankle. The examiner then determines how much inversion is present.

What is the treatment for a fractured talus?

Talus fractures may be treated in a cast or surgery may be recommended. Non-surgical treatment is recommended for fractures in which the pieces of bones remain close together and the joint surfaces are well-aligned.

How is talar tilt performed?

The talar tilt test, or inversion stress maneuver, is performed with the patient supine or on his/her side, with the foot relaxed. The gastrocnemius must also be relaxed by flexion of the knee. The talus is then tilted from side to side into adduction and abduction.

What are Hawkins type III talar neck fractures?

Hawkins type III talar neck fractures indicate injuries to the tibiotalar and subtalar joints [ 8 ]. Therefore, the management goal of this fracture is anatomic reduction, which requires attention to proper rotation, length, and angulation of the neck [ 9 ].

What is type IV talar neck fracture?

A type IV fracture, which consists of a dislocation at the subtalar, tibiotalar, and talonavicular joint, was subsequently added by Canale and Kelly [ 6 ]. A distinction between talar neck fractures and body fractures is not made in this system.

How are talar fractures of the talus classified?

Fractures of talus are mainly classified by their location: head, neck, and body [ 4 ]. Between 50 and 80% of all talar fractures occur in the neck, whereas only 13 to 23% of talar fractures occur in the body, and only 5 to 10% at the head [ 4 ].

What is the blood supply to the talar neck?

Blood supply talar neck supplied by three sources posterior tibial artery via artery of tarsal canal (dominant supply) supplies majority of talar body. deltoid branch of posterior tibial artery supplies medial portion of talar body. may be only remaining blood supply with a displaced fracture.
