S52.362S Displaced segmental fracture of shaft of radius, left arm, sequela

Name of the Condition

Displaced segmental fracture of shaft of radius, left arm, sequela
ICD-10 Code: S52.362S

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. The term "sequela" indicates this is a residual condition resulting from a previous fracture. This injury may cause persistent functional impairment, deformity, or chronic pain, depending on the healing process and any associated complications. The "left arm" specification denotes the affected side.

Causes

This condition arises as a complication of a prior displaced segmental fracture of the radius shaft. The original fracture typically resulted from significant trauma, such as falls onto an outstretched arm, direct blows to the forearm, or high-impact events like motor vehicle collisions. The sequela develops due to incomplete healing, malunion, or persistent instability of the bone fragments.

Risk Factors

• Inadequate initial fracture management or nonunion
• Poor bone healing due to underlying conditions (e.g., osteoporosis, diabetes)
• High-impact trauma leading to severe initial injury
• Delayed or incomplete rehabilitation after the original fracture

Symptoms

• Chronic pain or discomfort in the forearm
• Visible deformity or misalignment of the radius
• Reduced range of motion in the wrist or elbow
• Weakness or instability during arm use
• Possible nerve or tendon irritation from malaligned bone fragments

Diagnosis

Diagnosis involves a clinical evaluation of the affected arm, including assessment of pain, deformity, and functional limitations. Imaging studies, such as X-rays or CT scans, are used to confirm the presence of a malunited or nonunion fracture and evaluate bone alignment. The history of a prior fracture is critical to establishing the sequela diagnosis.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to strengthen surrounding muscles and improve mobility, pain management, or surgical intervention to realign or stabilize the bone if functional impairment is significant. Bracing or orthotics may also be used to support the arm during daily activities.

Prognosis and Follow-Up

Prognosis depends on the severity of the residual deformity and functional impact. Many patients experience improved function with rehabilitation, though some may have persistent limitations. Regular follow-up with a healthcare provider is recommended to monitor healing, address complications, and adjust treatment plans as needed.

Complications

• Chronic pain or arthritis in the wrist or elbow
• Nerve or tendon damage from malaligned bone
• Reduced grip strength or arm function
• Psychological impact from long-term disability

Lifestyle & Prevention

• Engage in regular strength and flexibility exercises to support arm function.
• Use protective gear during high-risk activities to prevent future injuries.
• Follow post-fracture care instructions to optimize healing and reduce sequela risk.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new deformity, or loss of function in the affected arm. Prompt evaluation is important to address complications or adjust treatment plans.

Tips for Medical Coders

Use S52.362S for a displaced segmental fracture of the radius shaft, left arm, when the condition is a sequela of a prior fracture. Document the history of the original injury and any residual symptoms or functional limitations to support the sequela diagnosis. Ensure the code aligns with clinical findings and prior fracture documentation.
