Q
In unstable conditions (e.g. Plaster of Paris), fracture repair occurs in four phases;
- ? (1-? days): the fracture ends ?, leading to ?
formation around the fracture site and an ? response creating a
? & ? network. - ? Callus (?-3 weeks): As ? at the fracture ends is reduced, the vascular network ? and ? tissue replaces the ?.

Q
In unstable conditions (e.g. Plaster of Paris), fracture repair occurs in four phases;
- Hard ? (1-? months): ? of the soft ? takes over 1-?
months, forming ? calcified tissue. - ?: once the fracture is solidly ?, ? takes place over
the following months to years, with the new ? bone being replaced by
? bone, and the ? ? being restored.
