S42.335S Nondisplaced oblique fracture of shaft of humerus, left arm, sequela

Name of the Condition

• Nondisplaced oblique fracture of shaft of humerus, left arm, sequela
• ICD Code: S42.335S

Summary

This condition represents a healed or healing nondisplaced oblique fracture of the left humerus shaft, with residual effects or complications persisting after the acute phase. The term "sequela" indicates ongoing consequences of the original injury, such as chronic pain, limited mobility, or structural changes, rather than an active fracture.

Causes

Sequela of a humerus shaft fracture typically result from the initial injury and its healing process. The original fracture may have been caused by trauma like falls, accidents, or high-impact events. Residual effects can arise from incomplete healing, malunion, or persistent inflammation at the site.

Risk Factors

• Prior history of humerus fracture or injury.
• Inadequate initial treatment or rehabilitation.
• Underlying conditions affecting bone healing (e.g., diabetes, vascular disease).
• Advanced age or poor bone health.

Symptoms

• Chronic pain or discomfort in the upper arm.
• Reduced range of motion or stiffness in the shoulder or elbow.
• Visible or palpable deformity at the fracture site.
• Weakness or instability during arm use.
• Possible nerve irritation or sensory changes.

Diagnosis

Diagnosis involves reviewing the patient’s history of the original fracture and current symptoms. Physical examination assesses residual deformity, mobility, and tenderness. Imaging, such as X-rays or CT scans, may be used to evaluate bone alignment and healing status. Functional assessments help determine the impact on daily activities.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to restore strength and mobility, pain management with medications or injections, and adaptive devices (e.g., braces) for support. In severe cases, surgical intervention to correct malunion or remove hardware may be considered.

Prognosis and Follow-Up

Prognosis depends on the severity of residual effects and adherence to rehabilitation. Most patients experience improved function with therapy, though some may have permanent limitations. Regular follow-up with a healthcare provider monitors healing and adjusts treatment as needed.

Complications

• Chronic pain or arthritis at the fracture site.
• Nerve damage leading to numbness or weakness.
• Reduced arm function or mobility.
• Psychological impact from persistent symptoms.

Lifestyle & Prevention

• Engage in regular, low-impact exercise to maintain arm strength.
• Use proper techniques for lifting or repetitive arm movements.
• Protect the arm from further injury with padding or avoidance of high-risk activities.
• Maintain bone health through diet and supplements if recommended.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or deformity develops, or daily activities become significantly impaired. Prompt evaluation is important if signs of infection (e.g., redness, fever) or nerve compression (e.g., sudden weakness) occur.

Tips for Medical Coders

This code is used for sequelae of a nondisplaced oblique fracture of the left humerus shaft. Documentation should specify the residual effects (e.g., chronic pain, limited mobility) and confirm the fracture is no longer acute. Ensure the sequela is directly linked to the original injury and not a new condition.
