The incidence, characteristics, and treatment of fractures in children are different from those in adults; strictly speaking, it can even be said to be very different! This is because children’s bones are still growing and immature, which can be described by the phrase “the hard part is soft, the soft part is hard”; the first phrase refers to the bones that are theoretically hard, but in fact are not strong enough to be broken easily; the second phrase refers to the ligaments, tendons, periosteum and other tissues that are theoretically soft, but are stronger than the bones, and are less likely to break from the body. The second sentence refers to the theory that ligaments, tendons, periosteum and other tissues should be softer and tougher than bones, which are less likely to be injured from the body and more likely to cause lacerated fractures attached to the bone. Therefore, children’s bones are easily fractured when they are compressed by difficult births, jumping from high places, falling and rolling, or being hit by vehicles. Fortunately, children have three major potentials: first, healing potential; because of the strong and thick periosteum and blood circulation, greenstick fractures and non-displaced fractures are quite common; even if they are displaced, the fractures heal quickly by repair. The rate and potential of fracture healing by repair is also particularly good. The growth potential is because the bones of children still have a growth plate. As long as the fracture does not damage the growth plate, the healing bone will bring a lot of stimulation and blood circulation to the adjacent growth plate to stimulate it to grow faster or longer! Therefore, many fractures, even if they cause a little bit of short and long feet, will gradually catch up in the growth process and become equal in length. In case the fracture is not straight or has a slight rotational deformation, the tension balance of the muscles stimulates the periosteum to produce bone in response to the pressure and break bone in response to the tension, and the growth plate stimulates the growth, so that the bending and hanging deformation within a certain degree will return to normal. Because children’s fractures have so much potential, the general public is making a big mistake if they think that a child’s fracture can be treated by a Chinese herbalist or a bone-setting clinic. This is because: a. Children’s fractures are sometimes not easy to diagnose, and it is easy to make the mistake of “overdiagnosing a serious case” or “overdiagnosing a minor case”! A non-displaced or incomplete fracture that is pulled by the periosteum may be mistaken for no fracture, and this is “overdiagnosis”! Because of pain or bruising and swelling after an accident, mistaking a growth plate or growth line for a fracture on X-ray is a “minor reassessment”. Second, ignore the physeal injury of the growth plate itself. This is the most terrible sequelae of ignoring the growth plate injury. Third, ignore the injury of articular cartilage (intra-articular fracture). Some fractures and their fracture lines extend into the joint, causing unevenness of the articular cartilage; if they are not detected and reset and allowed to heal, the joint will easily become stiff or degenerate in the future. Ignore the avulsion fracture of tendon attachment. Some block fractures are actually caused by the tendon attaching to it, and the tendon is pulled excessively and fractured during the accident. Fractures in children may seem easy but are actually difficult; improper treatment may result in joint contracture, limb deformation, functional impairment, long and short limbs or limp, traumatic joint degeneration, etc., and should not be taken lightly.
