S52.325R Nondisplaced transverse fracture of shaft of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion

Name of the Condition

Nondisplaced transverse fracture of shaft of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion

Summary

A nondisplaced transverse fracture of the shaft of the left radius is a horizontal break in the long, outer bone of the forearm (radius) where the bone fragments remain aligned, but the fracture is open (skin is broken) and has healed with malunion (improper alignment). This injury typically results from trauma and requires ongoing management to address healing complications and functional outcomes.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving twisting forces at the wrist or elbow. High-impact events like motor vehicle collisions or sports injuries can also cause the bone to break in a transverse pattern. Open fractures (types IIIA, IIIB, or IIIC) involve significant soft tissue damage, increasing the risk of malunion during healing.

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
• Delayed or inadequate initial fracture management

Symptoms

• Persistent pain at the fracture site, even after initial healing
• Swelling, bruising, or deformity of the forearm
• Limited range of motion in the wrist or forearm
• Visible bone protrusion through the skin (in open fractures)
• Numbness or tingling in the hand or fingers due to nerve involvement
• Functional impairment, such as difficulty gripping or lifting objects

Diagnosis

Diagnosis involves a physical examination to assess alignment, range of motion, and soft tissue damage. Imaging tests, such as X-rays or CT scans, confirm the fracture type, malunion, and any associated complications. Additional evaluations may include nerve function tests or wound assessments for open fractures.

Treatment Options

Treatment focuses on addressing malunion and restoring function. Options may include:

• Orthopedic consultation for potential surgical realignment or fixation
• Physical therapy to improve strength and mobility
• Pain management with medications or modalities
• Monitoring for infection or delayed healing in open fractures
• Assistive devices (e.g., braces) to support recovery

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and associated complications. Most patients achieve functional recovery with appropriate treatment, though some may experience long-term stiffness or weakness. Follow-up care typically involves regular imaging and clinical assessments to monitor healing and adjust interventions as needed.

Complications

• Chronic pain or discomfort
• Limited range of motion or functional impairment
• Nerve damage or vascular compromise
• Infection (especially in open fractures)
• Delayed or nonunion of the fracture
• Long-term deformity or cosmetic concerns

Lifestyle & Prevention

• Avoid high-risk activities or use protective gear during sports
• Maintain bone health through diet and exercise to reduce fracture risk
• Follow post-injury rehabilitation plans to optimize healing
• Use proper lifting techniques to prevent repetitive stress injuries
• Seek prompt medical care for suspected fractures to minimize complications

When to Seek Professional Help

Consult a healthcare provider if you experience:

• Worsening pain, swelling, or deformity
• Signs of infection (e.g., redness, pus, fever)
• Numbness, tingling, or weakness in the hand or fingers
• Difficulty moving the wrist or forearm after initial treatment
• Concerns about fracture alignment or healing progress

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC), malunion, and subsequent encounter details to support accurate coding. Include clinical notes on alignment, soft tissue involvement, and treatment plans to clarify the diagnosis and justify the code selection.
