Q

What is a torus fracture?

A

Also known as buckle fractures, are incomplete fractures of the shaft of a long bone that is characterised by bulging of the cortex. They result from trabecular compression from an axial loading force along the long axis of the bone. They are usually seen in children, frequently involving the distal radial metaphysis.

Q

What is a boxer’s fracture?

A

colloquial term for a fracture of one of the metacarpal bones of the hand. Classically, the fracture occurs transversely across the neck of the bone, after the patient strikes an object with a closed fist.

What is the usual presentation of hip dislocations?

A

Foot internally rotated with a huge amount of pain

29
Q

What x-ray views in particular must be obtained with hip dislocations?

A

Lateral

30
Q

What is the major reason there is avascular necrosis with hip dislocations?

A

Medial circumflex runs through femoral head, and will kink or rupture with dislocation

Q

Where do femoral fractures usually occur?

A

Midshaft

35
Q

What happens to the patella and quads with femoral shaft fractures?

A

Patella is displaced superiorly, and quads spasm
