Patients who have an undisplaced fracture of the elbow, also known as a cleft fracture of the elbow, will feel significant symptoms in the elbow, such as elbow pain, swelling of the elbow, subcutaneous bruising, pressure pain in the elbow joint, percussion pain, and limited flexion and extension of the elbow joint. A clear diagnosis can be made by performing an X-ray of the elbow after a bone fracture has occurred. Patients with this condition must have fixed support for the elbow, and local cold compresses can be applied later with hot compresses to help activate blood circulation and eliminate blood stasis, reduce swelling and pain. When the affected limb has significantly improved, the necessary functional exercises should be performed under the guidance of the doctor to promote the swelling and functional recovery of the affected limb. In addition to fixation and functional exercise during the recovery period, it is also important to eat a diet high in protein and calcium, which can promote the healing of the bone fracture.
