S52.365 Nondisplaced segmental fracture of shaft of radius, left arm

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, left arm
ICD-10 Code: S52.365

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.

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
• Visible bone protrusion through the skin (in open fractures)
• Numbness or tingling in the hand or fingers

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays or CT scans to confirm the fracture pattern and verify that the bone fragments are nondisplaced. Additional tests may be performed to evaluate soft tissue damage or nerve involvement.

Treatment Options

Treatment typically includes immobilization with a cast or splint to stabilize the fracture and allow healing. Pain management and activity modification are standard. In some cases, surgical intervention may be required if the fracture is unstable or if there is associated soft tissue injury.

Prognosis and Follow-Up

Prognosis is generally favorable with proper immobilization and follow-up care, as nondisplaced fractures often heal well. Follow-up appointments are necessary to monitor healing progress, typically with repeat imaging to ensure the bone is aligning correctly. Physical therapy may be recommended to restore strength and mobility once healing is advanced.

Complications

Potential complications include nonunion (failure to heal), malunion (healing in an incorrect position), nerve or blood vessel damage, or chronic pain. Infection may occur if the fracture is open. Long-term stiffness or reduced function is possible but less likely with nondisplaced fractures.

Lifestyle & Prevention

Preventive measures include using protective gear during high-risk activities, maintaining bone health through diet and exercise, and avoiding falls by modifying the home environment. Strengthening exercises for the forearm and wrist may help reduce injury risk.

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, redness). Numbness, tingling, or coldness in the hand or fingers also warrants prompt evaluation.

Tips for Medical Coders

Document the fracture as "nondisplaced" and specify the left arm to accurately reflect the code S52.365. Ensure clinical notes confirm the segmental nature (two or more fracture lines) and lack of displacement. Include details on imaging findings and treatment approaches to support coding accuracy.
