S42.015S Posterior displaced fracture of sternal end of left clavicle, sequela

Name of the Condition

• Posterior displaced fracture of sternal end of left clavicle, sequela (ICD-10 Code: S42.015S)

Summary

This condition represents a residual effect following a posterior displaced fracture of the sternal end of the left clavicle. The term "sequela" indicates a complication or condition resulting from the original fracture, which may involve persistent symptoms, structural changes, or functional limitations. The clavicle, or collarbone, connects the arm to the body, and fractures at its sternal end can lead to long-term consequences if not fully resolved.

Causes

Sequela arise from the initial posterior displaced fracture of the sternal end of the left clavicle, which typically results from direct trauma to the shoulder or chest, such as a fall, blow, or motor vehicle accident. The posterior displacement occurs when the fracture fragment moves toward the back of the body. Unresolved healing, malunion, or incomplete recovery from the original injury can lead to lasting effects.

Risk Factors

Factors increasing the risk of sequela include inadequate initial treatment, poor bone healing due to osteoporosis or other bone conditions, and high-energy trauma that causes significant displacement. Older adults or individuals with compromised bone health may be more prone to developing long-term complications.

Symptoms

Symptoms may include persistent pain, swelling, or tenderness at the sternal end of the left clavicle. Functional limitations, such as reduced shoulder mobility or arm strength, and visible or palpable deformity may also occur. Some individuals may experience chronic discomfort or nerve irritation due to the residual effects of the fracture.

Diagnosis

Diagnosis involves a physical examination to assess residual pain, deformity, or functional impairment. Imaging studies, such as X-rays or CT scans, may be used to evaluate bone alignment and healing. Clinical correlation with the patient’s history of the original fracture is essential to confirm the sequela.

Treatment Options

Treatment focuses on managing symptoms and improving function. This may include pain relief, physical therapy to restore mobility and strength, and, in some cases, surgical intervention to correct malunion or address structural issues. Supportive measures, such as bracing or activity modification, may also be recommended.

Prognosis and Follow-Up

Prognosis varies depending on the severity of the original injury and the extent of residual effects. Most individuals experience improvement with appropriate management, though some may have persistent limitations. Regular follow-up with a healthcare provider is important to monitor healing and adjust treatment as needed.

Complications

Complications can include chronic pain, reduced range of motion, nerve damage, or arthritis in the affected area. In rare cases, nonunion (failure of the bone to heal) or malunion (healing in an incorrect position) may occur, requiring further intervention.

Lifestyle & Prevention

Lifestyle modifications, such as avoiding activities that strain the shoulder or clavicle, can help manage symptoms. Preventive measures for future injuries include using protective gear during sports and maintaining bone health through exercise and proper nutrition.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or deformity develops, or functional limitations interfere with daily activities. Prompt evaluation is important if signs of infection, such as redness, warmth, or drainage, are present.

Tips for Medical Coders

This code is used for sequelae of a posterior displaced fracture of the sternal end of the left clavicle. Document the relationship between the sequela and the original fracture, including the time elapsed since the injury and any residual effects. Ensure the code is reported only when the sequela is the focus of treatment or evaluation.
