An avulsion fracture of the stem of the ulna is a fracture that occurs after a traumatic injury due to the pulling of ligaments or the impact of the wrist joint.
An avulsion fracture is a special type of fracture that occurs when the tendon or ligament to which the bone is attached is subjected to a strong force in the opposite direction during strenuous exercise or severe trauma, resulting in a strong contraction within a short period of time, causing the bone fragments attached locally to become avulsed.
The symptoms of ulnar stem avulsion fracture are similar to those of common fracture, mainly manifested as pain and swelling at the fracture site, obvious compression pain, and limited joint movement. Usually, conservative treatment can be adopted, such as resting, braking, plaster or brace immobilization and other treatments.
If diagnosed with ulnar stem avulsion fracture, it is recommended that the patient actively cooperate with the doctor and carry out standardized treatment as soon as possible in order to reduce the adverse effects of the disease.
