The initial treatment options for supracondylar humerus fracture include conservative treatment, surgical treatment and so on. 1. Conservative treatment: For undisplaced supracondylar humerus fracture, it can be immobilized by plaster or small splint. For slight displacement, the fracture can be stabilized by manipulation and then immobilized by plaster, small splint or percutaneous Kirschner pin for 4~6 weeks. 2. Surgical treatment: if external fixation by manipulation cannot be used, patients should consider internal fixation by incision and reduction in time, through which the continuity and integrity of the fracture can be restored. The blood circulation of the limb and the sensory and motor function of the hand should also be closely observed after surgery. Patients with supracondylar humerus fracture should go to the orthopedic department of regular hospitals in time, and take targeted treatment programs under the guidance of professional doctors.
