A severely broken or injured hip can require replacment in some cases. In other cases it can require surgery, bed rest, a cast, or limited mobility- sometimes for months.
A twisted or bruised hip would cause difficulty walking for about a week, or until it healed. As always, once anything has been injured it will always be slightly weaker and more susceptible to reinjury.
As to a bullet wound in a shoulder, it would depend where in the shoulder it hit. If it broke a bone, if would require a cast and cause limited mobility. A severe wound could require indepth surgery. However, if it simply hit muscle, it would require only minor surgery {assuming it didn't hit anything vital} and limited mobility.
Basically, you can decide the severity of the injuries and go from there.
