S42.142B Displaced fracture of glenoid cavity of scapula, left shoulder, initial encounter for open fracture

Name of the Condition

• Displaced fracture of glenoid cavity of scapula, left shoulder, initial encounter for open fracture

Summary

A displaced fracture of the glenoid cavity of the scapula, left shoulder, initial encounter for open fracture, refers to a break in the socket portion of the left shoulder blade that articulates with the humerus, where the bone fragments are not aligned and the skin is breached. This condition involves damage to the glenoid, a critical structure for shoulder joint stability, and may affect mobility and function. Displacement indicates the fracture fragments have shifted from their normal anatomical position, and the open nature of the fracture means the injury communicates with the external environment, increasing infection risk.

Causes

Traumatic injury is the primary cause of this fracture. Common mechanisms include falls onto the shoulder, motor vehicle accidents, sports-related impacts, or direct blows to the shoulder area. High-energy trauma, such as that from a collision, often results in displaced fractures due to the force required to shift bone fragments and breach the skin.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, which may increase susceptibility to falls.
• Previous shoulder or upper arm injuries that affect bone integrity.

Symptoms

• Pain in the left shoulder or upper back, especially with movement.
• Swelling, bruising, or tenderness over the shoulder joint.
• Limited range of motion in the shoulder.
• Difficulty lifting or rotating the arm.
• Visible wound or open skin at the fracture site.
• Possible joint instability or deformity.

Diagnosis

Diagnosis begins with a clinical evaluation, including a detailed history of the injury and physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are typically used to confirm the fracture, assess displacement, and evaluate the open wound. The open nature of the fracture may require additional assessment for contamination or infection.

Treatment Options

Treatment focuses on stabilizing the fracture, managing the open wound, and preventing infection. This may include surgical intervention to realign and fix the bone fragments, followed by wound care and antibiotics. Immobilization with a sling or brace is often necessary to support healing. Physical therapy may be recommended after initial healing to restore function.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the presence of complications. Most patients recover with proper care, but open fractures carry a higher risk of infection or delayed healing. Follow-up appointments are essential to monitor healing, assess for complications, and guide rehabilitation.

Complications

• Infection at the fracture site.
• Delayed union or nonunion of the fracture.
• Nerve or blood vessel damage.
• Chronic shoulder pain or instability.
• Limited range of motion or functional impairment.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if needed, especially in older adults.
• Seek prompt medical care for shoulder injuries to prevent complications.

When to Seek Professional Help

Seek immediate medical attention if you experience severe shoulder pain, visible deformity, an open wound, or inability to move the arm after an injury. Signs of infection, such as increased redness, pus, or fever, also require urgent evaluation.

Tips for Medical Coders

Document the laterality (left shoulder), displacement, and open fracture status clearly. Include details about the initial encounter and any associated wound care or surgical procedures. Ensure the open fracture is distinguished from a closed fracture, as this impacts coding and clinical management.
