S52.244A Nondisplaced spiral fracture of shaft of ulna, right arm, initial encounter for closed fracture

Name of the Condition

• Nondisplaced spiral fracture of shaft of ulna, right arm, initial encounter for closed fracture

Summary

A nondisplaced spiral 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) with a spiral pattern and no misalignment of bone fragments. This fracture typically results from rotational forces and involves the right arm, with the fracture site remaining in its normal anatomical position. The term "initial encounter for closed fracture" indicates this is the first episode of care for a fracture without an open wound.

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 twisting 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 (though nondisplaced fractures may not show obvious deformity).

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture pattern and verify nondisplacement. Documentation must specify the fracture is closed (no open wound) and the encounter is initial.

Treatment Options

Immobilization with a cast or splint to stabilize the fracture. Pain management with over-the-counter or prescription medications. Follow-up imaging to monitor healing. Physical therapy may be recommended once the fracture shows signs of union.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments are typically scheduled to assess healing progress, often with repeat X-rays. Full recovery may take several weeks to months, depending on the individual's health and adherence to treatment.

Complications

Delayed healing or nonunion if the fracture does not mend properly. Malunion if the bone heals in an abnormal position. Nerve or blood vessel damage, though less common with nondisplaced fractures. Chronic pain or stiffness in the forearm.

Lifestyle & Prevention

Avoid high-risk activities that increase fall or injury likelihood. Use protective gear during sports or manual labor. Maintain bone health through a balanced diet rich in calcium and vitamin D. Engage in regular weight-bearing exercise to strengthen bones.

When to Seek Professional Help

Severe pain that does not improve with rest or medication. Numbness, tingling, or coldness in the hand or fingers (signs of nerve or blood vessel involvement). Visible deformity or inability to move the arm. Signs of infection, such as increased redness, swelling, or fever.

Tips for Medical Coders

Document the fracture as nondisplaced, spiral, and involving the shaft of the ulna in the right arm. Specify the encounter as initial for a closed fracture. Ensure clinical notes confirm no displacement and the absence of an open wound to support accurate coding.
