S52.221 Displaced transverse fracture of shaft of right ulna

Name of the Condition

• Displaced transverse fracture of shaft of right ulna

Summary

A displaced transverse fracture of the shaft of the right ulna is a break in the long, straight portion of the ulna bone (one of the two forearm bones) where the bone fragments are shifted out of alignment. The fracture runs horizontally across the bone shaft, and the displacement indicates the bone pieces are not in their normal anatomical position.

Causes

Direct trauma to the forearm, such as from a fall, blow, or accident. High-impact injuries, including sports-related incidents or motor vehicle collisions. Indirect forces transmitted through the wrist or elbow, potentially causing a break in the ulna shaft.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other conditions that weaken bone density.
• Previous fractures or bone abnormalities that may predispose to injury.
• Advanced age, which can reduce bone strength.

Symptoms

• Pain and tenderness localized to the forearm.
• Swelling and bruising around the injured area.
• Difficulty moving the arm, wrist, or hand due to pain or instability.
• Possible visible deformity if the fracture is displaced.

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and evaluate alignment. Additional imaging (e.g., CT scans) may be used for complex fractures to assess displacement and bone fragments.

Treatment Options

• Immobilization using a cast or splint to support the ulna and promote healing.
• Pain management with medications such as nonsteroidal anti-inflammatory drugs (NSAIDs).
• Surgical intervention may be required for severe or displaced fractures to realign and stabilize the bone.

Prognosis and Follow-Up

Most displaced transverse fractures of the ulna shaft heal with proper treatment, though recovery time varies based on fracture severity and treatment approach. Follow-up appointments are typically scheduled to monitor healing, assess range of motion, and adjust treatment as needed. Physical therapy may be recommended to restore function.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in an incorrect position.
• Nerve or blood vessel damage near the fracture site.
• Infection, particularly if surgical intervention is required.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, construction).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Engage in regular weight-bearing exercise to support bone density.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, increased swelling, redness) after an injury.

Tips for Medical Coders

Document the fracture type (transverse), displacement, and laterality (right) clearly in the medical record. Ensure the code S52.221 is used only when the fracture is confirmed as displaced and transverse, with no additional details (e.g., open vs. closed) unless specified. Verify that the right ulna is explicitly documented to support the laterality.
