S52.245A Nondisplaced spiral fracture of shaft of ulna, left arm, initial encounter for closed fracture

Name of the Condition

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

Summary

A nondisplaced spiral fracture of the shaft of the ulna, left 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 left arm. The fracture is closed, meaning the skin is intact, and this is the initial encounter for treatment.

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 spiral 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 that the bone fragments are not displaced. Documentation of the fracture as closed and the initial encounter for treatment is essential.

Treatment Options

Immobilization with a cast or splint to stabilize the fracture and allow healing. Pain management with over-the-counter or prescription medications. Follow-up imaging to monitor healing progress. Physical therapy may be recommended once the fracture begins to heal to restore strength and mobility.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and follow-up care. Healing typically occurs within 6–8 weeks, but this may vary. Regular follow-up appointments are necessary to assess healing and adjust treatment as needed. Full recovery of function is common with appropriate care.

Complications

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

Lifestyle & Prevention

Avoid high-risk activities or use protective gear during sports. Maintain bone health through a balanced diet rich in calcium and vitamin D. Engage in regular weight-bearing exercise to strengthen bones. Use proper techniques to prevent falls, such as wearing appropriate footwear and removing tripping hazards at home.

When to Seek Professional Help

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

Tips for Medical Coders

Document the fracture as nondisplaced, spiral, and involving the shaft of the ulna in the left arm. Confirm the fracture is closed and note the initial encounter for treatment. Ensure the left arm specification and the absence of displacement are clearly recorded, as these details are critical for accurate coding.
