Classic complications following open fixation of talar neck fractures include osteonecrosis or avascular necrosis (AVN), posttraumatic arthritis, and malunion.[2]
What is a fixation pin?
It has pins that go through the skin and into the bone. The external fixator used for limb lengthening has bars (called struts) that are turned to slowly lengthen and realign the bone.
What defines the talar neck?
Talar neck fractures are high energy injuries to the hindfoot that are associated with a high incidence of talus avascular necrosis.
What plate and surgical approach is used most commonly for fixation of Pilon fractures?
Once the proper plate location has been determined, the correct surgical approach can be chosen. The 2 most commonly used approaches are antero- medial and anterolateral. Medial plating is best accomplished through the antero- medial approach. The skin incision begins on the lateral side of the tibial crest.
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.
How do you fix a talus fracture?
Most of the time fractures involving the talus require surgery. However, if the fracture is in a good alignment and seems stable, you might be treated without surgery using a splint or cast. If the bones are shifted out of place, surgery is usually needed to reset the bones.
What is ORIF procedure?
Open reduction and internal fixation (ORIF) is a type of surgery used to stabilize and heal a broken bone. You might need this procedure to treat your broken ankle. Three bones make up the ankle joint. These are the tibia (shinbone), the fibula (the smaller bone in your leg), and the talus (a bone in your foot).
Are bone screws permanent?
Your surgeon may use metal screws, pins, rods, or plates to secure the bone in place. These can be either temporary or permanent. Your doctor might recommend a bone graft if your bone shattered into fragments during your original injury.
How do I know if I broke my talus bone?
Your symptoms will vary greatly, depending on the type of talus fracture.
- Minimally displaced. Acute pain in the ankle is usually the first sign.
- Displaced. The pain, swelling, and tenderness are greater.
- Open. The most obvious symptom is the sight of bone sticking through the skin.
Why are pilon fractures so bad?
In many pilon fractures, a high-energy impact causes the injury. Because of the strong impact that causes this fracture, many people with pilon fractures have additional injuries. Healthcare providers classify pilon fractures according to their severity.
How do you fix a broken Pilon?
If your fibula is also broken, your doctor might first perform surgery to fix the fibular fracture and get your ankle back into place—and then apply an external fixator to hold your pilon fracture in place. Once the swelling and blisters go away, your doctor can then fix your tibia bone with metal plates and screws.
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).
What is the best fixation technique for the medial talar neck?
Screw fixation is appropriate in compression mode on the lateral side. The medial talar neck is often somewhat comminuted and can be reduced by using image intensification as a guide.
How do you fix a talar neck with cannulated screws?
K-wire placement is very important when using cannulated screws, as the position of the wires can help with definitive screw fixation. The lateral talar neck is usually not comminuted and can be reduced using fracture interdigitations. Screw fixation is appropriate in compression mode on the lateral side.
What is the role of K-wires in the fixation of talar neck fractures?
K-wires are helpful to achieve preliminary fixation. K-wire placement is very important when using cannulated screws, as the position of the wires can help with definitive screw fixation. The lateral talar neck is usually not comminuted and can be reduced using fracture interdigitations.
When is it necessary to adjust the fixator for external fixation?
If the fixator was initially applied rapidly when the patient was severely injured, once a decision has been made to continue external fixation as definitive treatment, it may be necessary to adjust the fixator or insert additional pins to obtain more secure fixation. 10. Case example An incision is made over the AIIS.
