displaced
Any kind of fracture that is possible to be imagined, from a greenstick incomplete nondislocated fracture to a comminuted open severely displaced fracture. The more common fractures are mid-diaphyseal (mid-shaft) fracture of the femur and the tibia, both open and closed, often displaced due to muscular contraction in reponse to trauma.
A few weeks or a month.
displaced fracture
This would be a hairline fracture or stress fracture. These only occur in weight bearing bones.
greenstick fracture
Greenstick fracture is a type of fracture where there is a faint line curving around the shaft of the arm bone. It is more common in children due to their softer bones. Instead of breaking completely, the bone bends and cracks on one side.

Your question is missing some information. The normal liver always crosses the midclavicular line. The missing information: how many centimeters did it percuss to at the midclavicular line.
About 3 months(12 weeks)
