S52.345 Nondisplaced spiral fracture of shaft of radius, left arm

Name of the Condition

Nondisplaced spiral fracture of shaft of radius, left arm
ICD-10 Code: S52.345

Summary

A nondisplaced spiral fracture of the shaft of the radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the fracture line spirals around the bone but the bone fragments remain in their normal alignment. This type of fracture typically results from rotational forces and is often stable, with minimal impact on arm function if treated appropriately. The severity and management depend on factors like the fracture pattern, associated soft tissue injury, and whether the fracture is open or closed.

Causes

This fracture commonly occurs due to indirect trauma, such as a fall onto an outstretched arm, twisting injuries to the wrist or forearm, or rotational forces during activities like sports or accidents. High-impact events, including motor vehicle collisions or falls from height, may also cause this type of fracture.

Risk Factors

• Participation in activities with a high risk of falls or rotational arm trauma (e.g., contact sports, gymnastics)
• Osteoporosis or weakened bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving repetitive stress or heavy lifting

Symptoms

• Sudden, localized pain at the injury site
• Mild swelling or bruising of the forearm
• Tenderness to touch
• Possible limited range of motion in the wrist or forearm
• No visible deformity (due to nondisplacement)

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion, followed by imaging studies. X-rays are the primary tool to confirm the fracture, assess the spiral pattern, and rule out displacement. In some cases, a CT scan may be used to evaluate the fracture in more detail, especially if the X-ray results are unclear or if there is concern for associated soft tissue injury.

Treatment Options

Treatment depends on the fracture's stability and the patient's overall health. Nondisplaced fractures are often managed with immobilization using a cast or splint to allow healing. Pain management and activity modification are typically recommended. Follow-up imaging may be performed to ensure proper healing. In rare cases, surgery may be considered if the fracture becomes displaced or if there are complications.

Prognosis and Follow-Up

The prognosis for a nondisplaced spiral fracture of the radius is generally favorable, with most patients recovering fully with appropriate treatment. Healing typically occurs within 6–8 weeks, but follow-up appointments are important to monitor progress and adjust treatment as needed. Physical therapy may be recommended to restore strength and range of motion once the fracture has healed.

Complications

While uncommon, potential complications include delayed healing, malunion (improper healing), or nonunion (failure to heal). Infection may occur if the fracture is open. Nerve or blood vessel injury is rare but possible, especially if there is significant trauma or displacement.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports)
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Avoid falls by removing home hazards and using assistive devices if needed
• Strengthen forearm muscles through regular exercise to improve stability

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, numbness or tingling in the hand, or if the injury is open (bone protruding through the skin). Follow up with a healthcare provider if pain worsens, swelling increases, or you notice decreased sensation or movement in the arm.

Tips for Medical Coders

When coding S52.345, ensure the documentation specifies a nondisplaced spiral fracture of the radius shaft in the left arm. Verify that the fracture is not displaced and that the location (left arm) is clearly documented. Differentiate between nondisplaced and displaced fractures, as this impacts code assignment. Confirm the absence of open fracture or additional injuries to avoid miscoding.
