S52.363 Displaced segmental fracture of shaft of radius, unspecified arm

Name of the Condition

Displaced segmental fracture of shaft of radius, unspecified arm
ICD-10 Code: S52.363

Summary

A displaced 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 are misaligned. This injury typically results from significant trauma and may impair arm function depending on the degree of displacement and associated soft tissue damage. The "unspecified arm" designation indicates the affected side is not documented.

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.

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 typically involves a physical examination to assess deformity, pain, and functional impairment, followed by imaging studies such as X-rays or CT scans to confirm the fracture pattern, displacement, and involvement of surrounding structures. Clinical evaluation may also include assessing neurovascular status to rule out associated injuries.

Treatment Options

Treatment depends on the severity of displacement, bone stability, and patient factors. Options may include closed reduction with casting for stable fractures, or surgical intervention (e.g., internal fixation with plates or rods) for unstable or severely displaced segments. Rehabilitation with physical therapy is often recommended to restore mobility and strength.

Prognosis and Follow-Up

Prognosis varies based on fracture alignment, treatment success, and associated injuries. Most patients recover function with appropriate management, though some may experience residual stiffness or strength deficits. Follow-up imaging and clinical assessments are typically scheduled to monitor healing and guide rehabilitation.

Complications

Potential complications include nonunion or malunion of the fracture, nerve or vascular injury, chronic pain, stiffness, or arthritis in the wrist or elbow. Infection may occur in open fractures requiring surgical intervention.

Lifestyle & Prevention

Preventive measures include using protective gear during high-risk activities, maintaining bone health through adequate calcium and vitamin D intake, and avoiding falls by modifying home environments (e.g., removing tripping hazards). Strengthening exercises for the forearm and wrist may help reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the arm, or signs of open fracture (e.g., bone protrusion). Persistent pain, swelling, or functional limitations after initial treatment also warrant evaluation.

Tips for Medical Coders

Document the fracture as "displaced segmental" with the unspecified arm designation. Ensure clinical documentation specifies displacement and segmental nature to support the code. Note that "unspecified arm" is used when the side is not documented; if later identified, the code should be updated to the specific arm (right or left) if applicable.
