S42.014 Posterior displaced fracture of sternal end of right clavicle

Name of the Condition

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

Summary

This condition involves a break at the sternal (chest) end of the right clavicle, with the bone fragment displaced backward. The clavicle, or collarbone, connects the arm to the body and is a common site for fractures due to its exposed position. Displacement indicates the bone fragments are not aligned, which may affect healing and require specific management.

Causes

Fractures of the clavicle’s sternal end typically result from direct trauma to the shoulder or chest, such as a fall onto the shoulder, a blow to the chest, or a motor vehicle accident. The posterior displacement specifically occurs when the fracture fragment moves toward the back of the body.

Risk Factors

Factors increasing the risk include participation in contact sports, osteoporosis or reduced bone density, and activities with a high risk of falls or collisions. Older adults may be more susceptible due to age-related bone changes.

Symptoms

Symptoms often include sudden pain at the sternal end of the right clavicle, swelling, bruising, and tenderness. A visible or palpable deformity may be present, along with difficulty moving the shoulder or arm due to pain.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and deformity. X-ray imaging is typically used to confirm the fracture and its displacement. Additional imaging like CT or MRI may be used for complex cases to evaluate surrounding structures.

Treatment Options

Treatment depends on the severity of displacement and patient factors. Non-displaced or minimally displaced fractures may be managed with immobilization (e.g., a sling) and pain relief. Displaced fractures may require closed reduction (realignment) or surgical fixation to restore alignment and promote healing.

Prognosis and Follow-Up

Most fractures heal within 6–12 weeks with appropriate treatment. Follow-up imaging may be used to monitor healing. Physical therapy is often recommended to restore strength and range of motion. Complications like nonunion or malunion are rare but possible with severe displacement or inadequate treatment.

Complications

Potential complications include nonunion (failure to heal), malunion (healing in an incorrect position), nerve or blood vessel injury near the fracture site, and chronic pain. Posterior displacement may increase the risk of injury to nearby structures like the trachea or major vessels.

Lifestyle & Prevention

Preventive measures include using protective gear during contact sports, maintaining bone health through adequate calcium and vitamin D intake, and avoiding high-risk activities. Strengthening shoulder and upper body muscles may help reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, difficulty breathing, or signs of nerve/vessel injury (e.g., numbness, discoloration). Follow up with a healthcare provider if pain worsens, swelling persists, or movement does not improve with treatment.

Tips for Medical Coders

Document the laterality (right clavicle) and displacement direction (posterior) clearly in the medical record, as these are key components of the code. Ensure the fracture is specified as involving the sternal end to justify the S42.014 code. Displacement should be confirmed via imaging or clinical assessment to support coding accuracy.
