Answer:
Bone fractures are a common injury and the healing process is complex.[1] Bone is one of a few tissues that is able to heal without forming a fibrous scar. There are two types of fracture healing – indirect (secondary) and direct healing (primary).[2]
Fracture of 4th Metacarpal Bone
Direct healing occurs when the bony fragments are fixed together with compression. There is no callus formation. The bony ends are joined and healed by osteoclast and osteoblast activity. [1]
Indirect healing is more common than direct healing and involves both endochondral and intramembranous bone healing.[2] Anatomical reduction and stable conditions are not required for indirect healing to occur.[2] Rather, there is a small amount of motion and weight bearing at the fracture, which causes a soft callus to form, leading on to secondary bone formation.[1] It should be noted though that too much load/movement can result in delayed healing or non-union,[2] which occurs in 5-10% of all fractures.[3]
Indirect healing usually occurs with:
non operative fracture treatment
operative treatments where some motion occurs at the fracture site, such as:
- Intramedullary nailing
- External fixation
- Internal fixation of comminuted fractures.
