S52.365A Nondisplaced segmental fracture of shaft of radius, left arm, initial encounter for closed fracture

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, left arm, initial encounter for closed fracture
ICD-10 Code: S52.365A

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 or more fragments that remain in their original alignment. This injury typically results from significant trauma and may impair arm function depending on associated soft tissue damage. The "nondisplaced" nature means the bone fragments are not shifted out of position, which can influence treatment and recovery. The "initial encounter for closed fracture" specifies this is the first treatment for a fracture where the skin is intact.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, high-impact blows to the forearm, or accidents involving twisting forces at the wrist or elbow. Motor vehicle collisions, sports injuries, or forceful impacts may also cause the bone to break into multiple segments 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
• Possible numbness or tingling if nerves are affected

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion, followed by imaging studies such as X-rays to confirm the fracture type and alignment. Additional imaging (e.g., CT scans) may be used to evaluate complex fractures. The "closed" nature of the fracture is confirmed by the absence of an open wound or skin penetration.

Treatment Options

Treatment depends on the fracture's stability and alignment. Nondisplaced fractures may be managed with immobilization (e.g., casting or splinting) to allow healing. Pain management and activity modification are often recommended. Severe cases or those with poor alignment may require surgical intervention, such as internal fixation with plates or screws, to stabilize the bone.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, with most patients regaining full function after proper immobilization and rehabilitation. Follow-up appointments are necessary to monitor healing via X-rays and adjust treatment as needed. Physical therapy may be recommended to restore strength and mobility once the fracture is stable.

Complications

Potential complications include malunion (improper healing), nonunion (failure to heal), nerve or blood vessel damage, chronic pain, or stiffness. Infection is not a risk for closed fractures but may occur if the fracture becomes open. Early intervention reduces these risks.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports)
• Maintain bone health through diet and exercise to reduce fracture risk
• Avoid falls by modifying environments (e.g., removing tripping hazards)
• Practice proper lifting techniques to prevent forearm injuries
• Seek prompt treatment for minor injuries to prevent progression

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, deformity, or inability to move the arm after an injury. Numbness, tingling, or coldness in the hand or fingers may indicate nerve or vascular damage and require urgent care.

Tips for Medical Coders

Document the fracture's location (shaft of radius, left arm), displacement status (nondisplaced), encounter type (initial), and fracture type (closed) to accurately assign S52.365A. Ensure clinical notes specify the absence of open wounds and confirm the initial treatment phase. Verify laterality (left arm) and segmental nature of the fracture to avoid miscoding.
