S52: Fracture of forearm

S52.0: Fracture of upper end of ulna

A fracture of the upper end of the ulna is a type of injury that occurs when there is a break in the uppermost section of the ulna bone. The ulna is one of the two long bones located in the forearm, with its upper end being near the elbow. This type of fracture can occur due to a variety of reasons; however, it is often the result of an accident or trauma, such as a fall where the person lands on an outstretched arm, or a direct blow or impact to the forearm. Common symptoms of a fracture of the upper end of the ulna might include pain, swelling, bruising, or an inability to move the forearm or elbow. In severe cases, there can be a visible deformity where the bone is misaligned or protruding through the skin. This condition requires immediate medical attention for proper assessment, diagnosis, and treatment.
