What is callus and fracture line

summary

In our daily life, fracture is very common, mostly caused by trauma. General X-ray after fracture shows that there is fracture line, which indicates that there is fracture. If there is no dislocation after fracture, plaster external fixation can be performed. If the fracture is dislocation, open reduction and internal fixation can be performed. No matter what treatment, callus will be formed in the process of recovery. Callus is a sign of fracture healing. Let's take a look at the following.

What is callus and fracture line

First: callus: callus refers to the callus formed in the healing process of bone injury. Fracture healing is generally divided into three stages: hematoma organization stage, original callus formation stage and callus remodeling stage; A variety of bone growth factors are related to fracture healing. They can stimulate the activity of osteoblasts and regulate local osteogenesis.

Second: the relationship between fracture line and callus: generally, the body may be fractured after trauma. After fracture, X-ray examination will show fracture line. After conservative treatment or open reduction and internal fixation, with the passage of time, the fracture line will gradually disappear and form callus. After the fracture line disappears, a large number of callus will appear.

Third: fracture line: fracture line is the unhealed line on the X-ray of the fracture site, which is an important sign to judge whether the fracture is clinical. If the fracture line does not disappear, it means that the fracture has not healed. According to the fracture line, it is generally divided into complete fracture and incomplete fracture.

matters needing attention

Fracture line and callus are the X-ray signs before and after fracture healing. If there is callus, it means that the bone has begun to grow. When the fracture does not form callus, it is generally absolutely not weight-bearing.
