S52.366S Nondisplaced segmental fracture of shaft of radius, unspecified arm, sequela

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, unspecified arm, sequela
ICD-10 Code: S52.366S

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 without misalignment. This injury typically results from significant trauma and may impair arm function depending on the degree of soft tissue damage. The "unspecified arm" designation indicates the affected side is not documented. The "sequela" modifier indicates this code is used for complications or conditions resulting from the fracture, rather than the acute injury itself.

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. Sequela arise from the residual effects of the initial injury, such as chronic pain, limited mobility, or deformity.

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

• Chronic pain or discomfort at the injury site
• Persistent swelling or bruising
• Reduced range of motion in the wrist or forearm
• Visible deformity or malalignment of the arm
• Numbness or tingling due to nerve involvement
• Difficulty performing daily activities requiring arm use

Diagnosis

Diagnosis involves a thorough clinical evaluation, including a review of the patient’s medical history and mechanism of injury. Physical examination assesses for tenderness, swelling, or deformity. Imaging studies, such as X-rays or CT scans, confirm the fracture type and assess for healing or residual issues. Additional tests, like nerve conduction studies, may be used if nerve damage is suspected.

Treatment Options

Treatment focuses on managing symptoms and addressing residual functional impairment. Options may include physical therapy to restore mobility and strength, pain management with medications, or assistive devices (e.g., braces) to support the arm. In some cases, surgical intervention may be considered to correct deformity or stabilize the bone if healing is incomplete.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury, the patient’s overall health, and adherence to treatment. Most patients experience improved function with rehabilitation, though some may have long-term limitations. Regular follow-up appointments monitor healing, assess functional recovery, and adjust treatment plans as needed.

Complications

• Chronic pain or arthritis in the affected joint
• Persistent stiffness or reduced range of motion
• Nerve damage leading to numbness or weakness
• Delayed union or nonunion of the fracture
• Post-traumatic arthritis
• Psychological impact, such as anxiety or depression related to functional limitations

Lifestyle & Prevention

• Engage in regular weight-bearing exercises to maintain bone density
• Use protective gear during high-risk activities (e.g., sports)
• Avoid repetitive motions that strain the forearm
• Ensure adequate calcium and vitamin D intake for bone health
• Practice fall prevention strategies, especially for older adults

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or signs of infection (e.g., redness, fever). Consult a healthcare provider if you notice persistent numbness, weakness, or difficulty moving the arm, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

Use S52.366S for sequelae of a nondisplaced segmental fracture of the radius shaft, unspecified arm. Document the nature of the sequela (e.g., chronic pain, deformity) and confirm the fracture is no longer in the acute phase. Ensure the code aligns with clinical notes indicating residual effects rather than the initial injury.
