S52.261H Displaced segmental fracture of shaft of ulna, right arm, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Displaced segmental fracture of shaft of ulna, right arm, subsequent encounter for open fracture type I or II with delayed healing

Summary

A displaced segmental fracture of the shaft of the ulna, right arm, is a break in the long, straight portion of the ulna bone (one of the two forearm bones) where the bone is broken into two or more separate fragments, and these fragments are misaligned. This is a subsequent encounter for an open fracture type I or II (where the skin is broken but contamination is minimal) with delayed healing, indicating the fracture has not progressed as expected during treatment. The injury involves the main body of the ulna and requires ongoing evaluation for proper alignment and healing.

Causes

Direct trauma to the right forearm, such as from a fall, blow, or accident. High-impact injuries, including sports-related incidents or motor vehicle collisions, may cause this type of fracture. Indirect forces transmitted through the wrist or elbow can also result in a segmental 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

• Persistent pain and tenderness localized to the right 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 remains displaced.
• Delayed healing may present as prolonged pain or lack of progress in fracture union.

Diagnosis

Physical examination to assess tenderness, swelling, and deformity. Imaging studies, such as X-rays or CT scans, to evaluate fracture alignment, fragment position, and healing progress. Assessment of the open wound (if present) to determine fracture type (I or II) and rule out infection. Review of prior treatment and healing timeline to confirm delayed healing.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture.
• Surgical intervention, such as internal fixation with plates or screws, if alignment is poor or healing is not progressing.
• Wound care for open fractures to prevent infection.
• Pain management with medications or other modalities.
• Physical therapy to restore range of motion and strength once healing allows.

Prognosis and Follow-Up

Prognosis depends on fracture severity, alignment, and response to treatment. Delayed healing may extend recovery time, requiring closer monitoring. Follow-up appointments with imaging to assess healing progress are typically scheduled every 4–6 weeks. Full recovery may take several months, with activity modifications recommended during the healing phase.

Complications

• Nonunion or malunion of the fracture.
• Infection, particularly with open fractures.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or stiffness in the forearm.
• Reduced function or strength in the arm.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, construction).
• Maintain bone health with adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Follow post-injury activity restrictions to support healing.

When to Seek Professional Help

Seek immediate care if there is severe pain, swelling, or deformity. Contact a healthcare provider if pain worsens, mobility decreases, or signs of infection (e.g., redness, pus, fever) develop. Follow up as scheduled to monitor healing progress.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (right arm), and encounter type (subsequent) clearly. Note the presence of delayed healing and any contributing factors (e.g., infection, poor alignment) to support code assignment. Ensure documentation aligns with the clinical findings and treatment provided.
