S42.017 Nondisplaced fracture of sternal end of right clavicle

Name of the Condition

• Nondisplaced fracture of sternal end of right clavicle (ICD-10 Code: S42.017)

Summary

A nondisplaced fracture of the sternal end of the right clavicle is a break in the inner portion of the right collarbone, where it connects to the sternum (breastbone). The bone fragments remain aligned, meaning there is no significant shift in position. This type of fracture involves the medial third of the clavicle and may range from minor cracks to complete breaks without displacement.

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. The nondisplaced nature suggests the force was not severe enough to shift the bone fragments.

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. The right clavicle may be more susceptible in certain scenarios, such as falls onto the right shoulder.

Symptoms

Symptoms often include localized pain at the sternal end of the right clavicle, swelling, bruising, tenderness, and difficulty moving the shoulder. A visible deformity or bump may be present at the fracture site, though displacement is absent. Pain may worsen with movement or pressure.

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 cases, though nondisplaced fractures are typically identified via X-ray. The absence of displacement is a key diagnostic feature.

Treatment Options

Treatment typically includes immobilization with a sling to support the arm and reduce movement. Pain management with over-the-counter or prescription medications may be recommended. Physical therapy is often introduced later to restore strength and mobility. Most nondisplaced fractures heal without surgery, but follow-up imaging may be used to monitor progress.

Prognosis and Follow-Up

The prognosis for a nondisplaced fracture is generally favorable, with most cases healing within 6–8 weeks. Follow-up appointments are important to assess healing and adjust treatment as needed. Complications are rare but may include delayed union or nonunion, which require further evaluation.

Complications

Complications are uncommon but may include persistent pain, limited shoulder mobility, or nonunion (failure to heal). Infection or nerve injury is rare but possible with severe trauma. Early intervention and adherence to treatment plans reduce these risks.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Strengthen shoulder and upper body muscles to improve stability. Use protective gear during sports or activities with fall risks. Maintain bone health through adequate calcium and vitamin D intake, especially for those with osteoporosis.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms like numbness or tingling develop. Return to a provider if the arm cannot be moved or if the fracture site shows signs of infection (redness, pus, fever). Follow-up is necessary if pain persists beyond expected healing time.

Tips for Medical Coders

Document the fracture as "nondisplaced" and specify the right clavicle to align with S42.017. Include details on trauma mechanism, imaging results, and treatment plan. Ensure the absence of displacement is clearly noted, as this distinguishes it from displaced fractures. Verify laterality (right) and anatomic site (sternal end) for accuracy.
