Most relevant risk factors for the development of avascular necrosis after femoral neck fractures do NOT include:
-
Type of fracture.
-
Occurrence of deviation.
-
Gender and race.
-
Quality of reduction.
-
-
Surgical or conservative treatment?
-
Closed reduction is recommended.
-
Fracture surgical fixation is recommended.
-
Immobilization is sufficient.
-
Reduction, immobilization and late surgery.
-
-
What kind of reduction (open or closed) is most appropriate in this type of fracture?
-
Closed treatment is the rule.
-
Always closed reduction.
-
Always open reduction.
-
Anatomical reduction (closed or open).
-
-
Does early hip decompression reduce the risk of avascular necrosis (AVN)?
-
Decompression of the early hematoma reduces the risk of AVN.
-
This does not interfere with the rate of AVN.
-
Decompression must be delayed to avoid infection.
-
It depends on the success of the closed reduction.
-
-
What is the maximum time between the accident and early therapeutic approach to minimize the most common complications?
-
The first 12 hours.
-
The first 24 hours.
-
The first 48 hours.
-
The first 72 hours.

-
Is the use of bone substitutes such as BMP (bone morphogenetic protein) safe and effective in lumbosacral arthrodesis?
Complications include osteolysis and heterotopic ossification. (Alternative B)
-
Bone substitutes are equal or superior to autografts in this situation?
The association of local bone graft (from the posterior vertebral elements) and beta-tricalcium phosphate is a therapeutic option. (Alternative C)
-
What is the most appropriate diagnostic study in this clinical context?
The most appropriate diagnostic test in this situation is plain radiography. (Alternative D)
-
Is it necessary to refer the patient to arthrodesis with use of rigid pedicle screws (non-dynamic)?
Instrumented fusion produces less progression and improved walking ability. (Alternative B)
-
For how long should non-surgical treatment be conducted?
After 12 weeks of failure in conservative treatment. (Alternative C)
