S52.354A Nondisplaced comminuted fracture of shaft of radius, right arm, initial encounter for closed fracture

Name of the Condition

Nondisplaced comminuted fracture of shaft of radius, right arm, initial encounter for closed fracture
ICD-10 Code: S52.354A

Summary

A nondisplaced comminuted fracture of the shaft of the radius involves a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the bone is shattered into multiple pieces but the fragments remain in their original alignment. This type of fracture is classified as closed, meaning the skin is intact, and it is documented as an initial encounter for treatment. The complexity of the fracture depends on the number of fragments and the extent of soft tissue involvement, though the lack of displacement may simplify management compared to displaced fractures.

Causes

This fracture typically results from high-impact trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving significant force (e.g., motor vehicle collisions, sports injuries). Twisting injuries or crush mechanisms can also cause the bone to break into multiple fragments without displacing them.

Risk Factors

• Participation in contact sports or activities with a high risk of falls
• 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, severe pain at the injury site
• Swelling, bruising, or deformity of the forearm
• Inability to move the wrist or forearm
• Tenderness to touch

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging. A physical exam assesses pain, swelling, and range of motion. X-rays are the primary imaging tool to identify the fracture pattern, confirm the absence of displacement, and rule out associated injuries. In some cases, CT scans may be used to better visualize fragment complexity.

Treatment Options

Treatment focuses on immobilization to allow healing. A cast or splint is typically applied to stabilize the arm. Pain management and activity modification are recommended. Surgical intervention is uncommon for nondisplaced fractures but may be considered if fragments become displaced or if there is significant soft tissue involvement.

Prognosis and Follow-Up

Prognosis is generally favorable with proper immobilization and adherence to treatment. Healing usually occurs within 6–8 weeks, after which gradual rehabilitation may be needed to restore strength and mobility. Follow-up appointments monitor healing progress and adjust treatment as necessary.

Complications

• Delayed union or nonunion of the fracture
• Malunion if fragments shift during healing
• Stiffness or reduced range of motion in the wrist or elbow
• Nerve or blood vessel injury (rare)

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports)
• Maintain bone health through adequate calcium and vitamin D intake
• Avoid falls by modifying home environments (e.g., removing tripping hazards)
• Strengthen forearm muscles to improve resilience

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, increased swelling). Follow up with a healthcare provider if pain worsens, swelling persists, or mobility does not improve with treatment.

Tips for Medical Coders

Document the fracture as nondisplaced and comminuted, specifying the right arm and initial encounter for a closed fracture. Ensure clinical notes confirm the absence of displacement and that the fracture is closed (skin intact). Code S52.354A is appropriate for the initial phase of treatment; subsequent encounters for the same injury would use different codes.
