Whether an avulsion fracture is serious or not depends mainly on the site of the fracture and cannot be generalized. Avulsion fractures are caused by a violent contraction of a muscle tendon that causes the bone to break. If only one bone is avulsed or the avulsion site is not at the ligament stop or joint site, the condition is mild and does not require surgery. Conservative treatment, such as plaster fixation for 6-8 weeks and regular review, is sufficient. After the fracture is healed, the rehabilitation function of the joint limb will be carried out. If the fracture site is at the stop of the ligament or in the joint, the condition is more serious and the effect of conservative treatment is generally not good, so active surgery is needed to reset and fix the fracture. Patients need to take oral anti-inflammatory and analgesic medications and drugs to promote fracture healing. When rehabilitating functional exercises, patients need to progress gradually and pay attention to the supplementation of appropriate multivitamins and high-quality protein powder to promote fracture healing.
