S52.364A Nondisplaced segmental fracture of shaft of radius, right arm, initial encounter for closed fracture

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, right arm, initial encounter for closed fracture
ICD-10 Code: S52.364A

Summary

A nondisplaced segmental 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 bone is separated into two distinct segments without misalignment. This injury typically results from trauma and is classified as closed (no skin penetration) and initial (first encounter for treatment). The "right arm" specification indicates the affected side. Nondisplaced fractures often have a better prognosis due to preserved bone alignment, but the segmental nature may still require stabilization to prevent displacement.

Causes

This fracture commonly occurs due to significant trauma, such as falls onto an outstretched arm, direct forceful impacts to the forearm, or twisting injuries. High-energy events like motor vehicle collisions or sports-related accidents may also cause the bone to break into multiple segments. The force required to create a segmental pattern suggests substantial impact or stress.

Risk Factors

• Participation in high-risk activities (e.g., contact sports, extreme sports)
• Osteoporosis or reduced bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving heavy lifting or repetitive stress

Symptoms

• Severe, localized pain at the injury site
• Swelling or bruising of the forearm
• Tenderness to touch
• Possible deformity (less common in nondisplaced fractures)
• Difficulty moving the wrist or forearm
• Numbness or tingling (if nerve involvement occurs)

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, typically X-rays, confirm the fracture type, location, and displacement. CT scans may be used for detailed visualization of complex fractures. The "closed" classification is determined by the absence of skin penetration, and "initial encounter" indicates the first treatment episode.

Treatment Options

Treatment focuses on immobilization with a cast or splint to maintain alignment and allow healing. Pain management and activity modification are standard. Nondisplaced fractures often heal without surgery, but close monitoring is necessary to ensure no displacement occurs. Physical therapy may be recommended during recovery to restore strength and function.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, with most patients regaining full function. Healing typically takes 6–8 weeks, followed by gradual return to normal activities. Follow-up appointments monitor healing progress and address any complications. Long-term outcomes depend on adherence to treatment and rehabilitation.

Complications

• Displacement of fracture fragments during healing
• Nerve or blood vessel damage (rare)
• Delayed union or nonunion of bone
• Stiffness or reduced range of motion
• Chronic pain (uncommon in nondisplaced cases)

Lifestyle & Prevention

• Use protective gear during high-risk activities
• Maintain bone health through diet and exercise
• Avoid falls by modifying home environments (e.g., removing tripping hazards)
• Strengthen forearm muscles to improve resilience
• Seek prompt treatment for minor injuries to prevent progression

When to Seek Professional Help

Seek immediate care if severe pain, swelling, or deformity occurs after an injury. Contact a healthcare provider if symptoms worsen, or if numbness, tingling, or inability to move the hand develops. Follow-up is necessary if pain persists or mobility does not improve.

Tips for Medical Coders

Document the fracture as nondisplaced, segmental, and confined to the shaft of the radius. Specify the right arm and confirm the encounter is initial for a closed fracture. Ensure clinical notes support the absence of displacement and skin penetration. Code S52.364A is appropriate for the initial encounter of this specific fracture type.
