S42.01 Fracture of sternal end of clavicle

Name of the Condition

• Fracture of sternal end of clavicle (ICD-10 Code: S42.01)

Summary

A fracture of the sternal end of the clavicle is a break in the inner portion of the collarbone, where it connects to the sternum (breastbone). This type of fracture involves the medial third of the clavicle and may range from minor cracks to complete breaks.

Causes

This fracture typically results from direct trauma to the shoulder or chest, such as a fall onto the shoulder, a motor vehicle accident, or a forceful impact to the sternum. It can also occur during contact sports or activities involving sudden force to the upper body.

Risk Factors

Factors that increase the risk include participation in high-impact sports, osteoporosis or reduced bone density, and older age due to increased fall risk. Anatomical variations in clavicle structure may also play a role.

Symptoms

Symptoms often include localized pain at the sternal end of the clavicle, swelling, bruising, tenderness, and difficulty moving the shoulder. A visible deformity or bump may be present at the fracture site.

Diagnosis

Diagnosis involves a physical examination to assess pain and deformity, followed by X-ray imaging to confirm the fracture and its location. Additional imaging like CT or MRI may be used for complex or displaced fractures.

Treatment Options

Treatment typically includes immobilization with a sling to support the arm, pain management, and physical therapy to restore mobility. Severe or displaced fractures may require surgical intervention to realign the bone.

Prognosis and Follow-Up

Most fractures of the sternal end of the clavicle heal well with conservative treatment. Follow-up care involves monitoring for proper healing and gradual return to normal activities, with physical therapy to strengthen the shoulder.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), nerve or blood vessel injury, or chronic pain. Infection may occur if surgery is performed.

Lifestyle & Prevention

Preventive measures include using protective gear during sports, maintaining bone health through diet and exercise, and avoiding high-risk activities. Strengthening shoulder muscles may help reduce injury risk.

When to Seek Professional Help

Seek medical attention if you experience severe pain, visible deformity, inability to move the shoulder, or signs of infection (e.g., fever, redness). Immediate care is needed for suspected open fractures or nerve damage.

Tips for Medical Coders

Document the specific location (sternal end) and any associated details (e.g., displacement, open/closed) to support accurate coding. Ensure the fracture is clearly differentiated from other clavicle injuries.
