S42.014S Posterior displaced fracture of sternal end of right clavicle, sequela

Name of the Condition

• Posterior displaced fracture of sternal end of right clavicle, sequela (ICD-10 Code: S42.014S)

Summary

This condition represents a sequela (late effect) of a previously treated posterior displaced fracture at the sternal end of the right clavicle. Sequela refers to residual effects or complications that persist after the acute phase of an injury has resolved. The clavicle, or collarbone, connects the arm to the body, and fractures at its sternal end may lead to long-term functional or structural changes if not fully healed or aligned.

Causes

Sequela of a posterior displaced clavicle fracture typically arise from incomplete healing, malunion (improper bone alignment), or persistent instability following the initial injury. The original fracture was likely caused by direct trauma to the shoulder or chest, such as a fall, blow, or accident, with the fragment displaced backward. Residual effects may develop if the initial injury was severe, poorly managed, or complicated by infection or poor blood supply.

Risk Factors

Risk factors for developing sequela include inadequate initial treatment, delayed or incomplete healing, osteoporosis, or high-impact trauma that caused significant bone damage. Older adults or individuals with compromised bone health may be more prone to long-term complications. Activities that stress the shoulder or clavicle could exacerbate residual issues.

Symptoms

Symptoms may include chronic pain at the sternal end of the right clavicle, reduced shoulder mobility, or a palpable deformity. Some patients experience intermittent discomfort with movement or weight-bearing, while others may have persistent swelling or stiffness. Functional limitations, such as difficulty lifting the arm, can also occur.

Diagnosis

Diagnosis involves a physical examination to assess residual deformity, pain, or instability. Imaging, such as X-rays or CT scans, may be used to evaluate bone alignment, healing, or signs of malunion. 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. Options may include physical therapy to restore mobility, pain management, or orthopedic devices (e.g., braces) for support. In severe cases, surgery to realign or stabilize the bone may be considered, though this depends on the extent of residual damage.

Prognosis and Follow-Up

Prognosis varies based on the severity of the sequela and response to treatment. Many patients achieve satisfactory function with conservative management, but some may experience chronic pain or limited mobility. Regular follow-up with an orthopedic specialist is recommended to monitor healing and adjust care as needed.

Complications

Potential complications include chronic pain, reduced range of motion, or arthritis in the acromioclavicular joint. Rarely, nerve or vascular damage from the original injury may persist. Malunion or nonunion (failure to heal) can also lead to long-term functional impairment.

Lifestyle & Prevention

Lifestyle modifications, such as avoiding heavy lifting or high-impact activities, may reduce strain on the affected area. Strengthening exercises for the shoulder and upper body, guided by a therapist, can improve stability. Preventing falls or trauma to the shoulder is key to avoiding future injuries.

When to Seek Professional Help

Seek care if chronic pain worsens, mobility declines significantly, or new symptoms (e.g., numbness, swelling) develop. Sudden increases in pain or deformity may indicate a new injury or complication requiring prompt evaluation.

Tips for Medical Coders

This code is used for sequela of a posterior displaced fracture of the sternal end of the right clavicle. Document the relationship to the original injury, including the time elapsed since the acute event and any residual effects. Ensure the sequela is clearly linked to the prior fracture in the medical record to support coding accuracy.
