A cleft fracture is a type of fracture that is an incomplete fracture and is a relatively minor fracture. A fracture is an interruption of the continuity and integrity of the bone. A cleft fracture is only a very small, subtle crack, the alignment and alignment of the bone is very good, there is no local deformity, and the functional impact is not great, and it can heal after 4-6 weeks of recuperation and rest without any residual sequelae. Although a cleft fracture is a minor fracture, care should be taken during the treatment period to rest with braking and fixation if necessary, as too much activity can cause the fracture to worsen and develop from a minor cleft fracture to a complete fracture, or even a displaced fracture, resulting in deformity of the limb. A cleft fracture is a minor fracture, but it should be treated with care and attention.
