S42.035 Nondisplaced fracture of lateral end of left clavicle

Name of the Condition

• Nondisplaced fracture of lateral end of left clavicle

Summary

A nondisplaced fracture of the lateral end of the left clavicle is a break in the outer portion of the left collarbone where the bone fragments remain in their normal alignment. This type of fracture involves the lateral (outer) segment of the clavicle, which connects to the shoulder joint, and typically results from trauma to the shoulder area.

Causes

Clavicle fractures often occur due to direct trauma to the shoulder, such as a fall onto the shoulder, a blow to the area, or a forceful impact during sports or accidents. Falls onto an outstretched hand may also transmit stress to the clavicle, leading to fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or weakened bone density.
• Older age, due to increased fall risk and bone fragility.
• Previous shoulder or clavicle injuries.

Symptoms

• Pain, swelling, or tenderness over the lateral clavicle.
• Bruising or discoloration around the shoulder.
• Difficulty moving the arm or shoulder.
• A visible bump or deformity at the fracture site (may be subtle in nondisplaced cases).

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and deformity. Imaging, typically X-rays, confirms the fracture and its location. In complex cases, CT or MRI may be used to evaluate alignment or associated soft tissue damage.

Treatment Options

• Immobilization with a sling or brace to support the shoulder and promote healing.
• Pain management with over-the-counter or prescription medications.
• Physical therapy to restore strength and mobility once healing progresses.
• Surgical intervention is rarely needed for nondisplaced fractures but may be considered if alignment is compromised.

Prognosis and Follow-Up

Most nondisplaced clavicle fractures heal well with conservative treatment. Recovery typically takes 6–8 weeks, with follow-up appointments to monitor healing through imaging. Full function usually returns, though some residual stiffness or mild discomfort may persist.

Complications

• Delayed union or nonunion of the fracture.
• Nerve or blood vessel injury near the fracture site.
• Chronic pain or shoulder instability.
• Malunion if the fracture shifts out of alignment during healing.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Practice fall prevention strategies, especially for older adults.
• Avoid falls by using assistive devices if needed.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., fever, redness, drainage) at the fracture site.

Tips for Medical Coders

Document the laterality (left) and the nondisplaced nature of the fracture clearly in the medical record. Ensure the fracture is specified as involving the lateral end of the clavicle, as this distinguishes it from other clavicle fracture locations.
