Healing of a fracture
The process of fracture healing varies according to the type of bone involved and the amount of movement at the fracture site. Following healing processes are there :‑
Indirect fracture healing (healing by callus)
This is the ‘natural’ form of healing in tubular bones and in the absence of rigid fixation when there is micromovement at fracture site. There is formation of internal and external callus. This stage is divided in three phases which are further subdivided into five stages :
