S42.02 Fracture of shaft of clavicle

Name of the Condition

• Fracture of shaft of clavicle (ICD-10 Code: S42.02)

Summary

A fracture of the shaft of the clavicle is a break in the middle portion of the collarbone, the bone connecting the arm to the body. This condition involves the central third of the clavicle and can range from minor cracks to complete breaks. It is a common type of clavicle fracture resulting from trauma.

Causes

This fracture typically results from direct trauma to the shoulder or a fall onto an outstretched hand. Common scenarios include sports injuries, motor vehicle accidents, or falls from a height. The force applied to the shoulder or arm often causes the clavicle shaft to break.

Risk Factors

Factors that increase the likelihood of a clavicle shaft fracture include participation in contact sports, osteoporosis or weakened bone density, and older age due to increased fall risk. Activities involving high-impact forces to the upper body also raise the risk.

Symptoms

Symptoms often include sudden pain in the shoulder or collarbone area, swelling, bruising, tenderness, difficulty moving the shoulder, and a visible bump or deformity at the fracture site. Pain may worsen with arm movement or pressure on the area.

Diagnosis

Diagnosis involves a physical examination to assess pain and deformity, followed by X-ray imaging to confirm the fracture and its location. In some cases, additional imaging like CT or MRI may be used for complex fractures to evaluate displacement or associated injuries.

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 and stabilize the bone.

Prognosis and Follow-Up

Most clavicle shaft fractures heal well with conservative treatment, though recovery may take several weeks. Follow-up appointments monitor healing progress, and physical therapy helps restore strength and range of motion. Complications are rare but may include nonunion or malunion.

Complications

Potential complications include nonunion (failure to heal), malunion (healing in an incorrect position), nerve or blood vessel injury, or chronic pain. Infection or hardware-related issues may occur with surgical treatment.

Lifestyle & Prevention

Preventive measures include using protective gear during contact sports, maintaining bone health through adequate calcium and vitamin D intake, and reducing fall risks in older adults. Avoiding high-impact activities that strain the shoulder may also help.

When to Seek Professional Help

Seek medical attention if you experience severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, redness). Immediate care is needed for open fractures or if there is numbness or tingling in the arm or hand.

Tips for Medical Coders

Document the specific location of the fracture (shaft of clavicle) and any associated details, such as displacement or open/closed status, to support accurate coding. Ensure the medical record clearly differentiates this from fractures of other clavicle parts (e.g., sternal or acromial ends) for precise code assignment.
