Functional recovery of ulnar humerus fracture should be based on one’s own condition and fracture healing, and the specific recovery time varies from person to person, generally it takes 2 to 3 months to resume normal activities. Clinical treatment of ulnar humerus fracture is usually divided into conservative treatment and surgical treatment. Conservative treatment can be carried out through the cast or support for braking and external fixation, while the surgical treatment is to use the incisional reduction and internal fixation for treatment. The ulnar humerus fracture is treated conservatively, under normal circumstances, the bone scab will start to form in about 6 to 8 weeks, and the cast can be removed to gradually carry out functional exercises, and the fracture will be basically healed in about 10 to 12 weeks, and the stability of the bone is good, so that the fracture can be restored to the normal working and living condition. If the damage of ulnar humerus fracture is serious, it is necessary to carry out incision and reduction internal fixation surgery, the fracture heals in 2~3 months after surgery, and normal functional activities are resumed, but the internal fixation material is usually not removed until 6~12 months after surgery, and during this period, it will affect the function of the limb and daily activities, which may prolong the recovery time. After treatment of ulnar humerus fracture, active rehabilitation training should be carried out under the guidance of doctors to promote early healing and return to health.
