S52.22 Transverse fracture of shaft of ulna

Name of the Condition

• Transverse fracture of shaft of ulna

Summary

A transverse fracture of the shaft of the ulna is a straight-line break across the long, central portion of the ulna bone, one of the two bones in the forearm. This fracture pattern involves a horizontal break through the bone shaft, which may or may not involve displacement of the bone fragments.

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 or comminution.

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 transverse fractures of the ulna shaft heal well with appropriate treatment, though recovery time depends on fracture severity and patient factors. 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 strength and 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, such as sports or manual labor.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• 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). Prompt evaluation is important to prevent complications and ensure proper healing.

Tips for Medical Coders

Document the fracture pattern (transverse) and location (shaft of ulna) clearly in the medical record. Ensure the code S52.22 is used when the fracture is specifically described as transverse and involves the shaft of the ulna. Include details about displacement, open/closed status, or subsequent encounter if applicable to support accurate coding.
