S42.112B Displaced fracture of body of scapula, left shoulder, initial encounter for open fracture

Name of the Condition

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

Summary

A displaced fracture of the body of the scapula involves a break in the main, flat portion of the shoulder blade bone, with the fractured fragments shifted out of their normal alignment. This condition affects the left shoulder and is classified as an open fracture, meaning the skin is broken, exposing the fracture site. The scapula connects the upper arm to the collarbone and trunk, and fractures in its body can impact shoulder function and require prompt medical attention due to the risk of infection.

Causes

Traumatic injury is the primary cause, often resulting from high-impact events such as motor vehicle accidents, falls from height, or direct forceful blows to the shoulder. Sports-related collisions, crush injuries, or penetrating trauma may also lead to this type of fracture. The force required to displace the bone fragments typically indicates significant trauma.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, which may increase susceptibility to fractures from minor trauma.
• Previous shoulder or upper arm injuries that affect bone integrity.

Symptoms

• Intense pain in the shoulder or upper back, worsening with movement.
• Swelling, bruising, or tenderness over the shoulder blade.
• Limited range of motion in the shoulder joint.
• Difficulty lifting or rotating the arm.
• Visible wound or open skin at the fracture site.
• Possible deformity or instability in severe cases.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture, evaluate displacement, and assess for open injury. The presence of an open wound is documented to classify the fracture as open. Additional tests may be performed to rule out associated injuries to surrounding structures.

Treatment Options

Treatment focuses on stabilizing the fracture and preventing infection. For open fractures, wound cleaning and debridement are performed to reduce infection risk. Immobilization with a sling or brace may be used to support healing. Surgical intervention may be necessary for severe displacement or unstable fractures. Pain management and physical therapy are often included in the recovery plan.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, treatment, and adherence to follow-up care. Most fractures heal with proper management, but open fractures carry a higher risk of complications like infection. Regular follow-up appointments monitor healing progress, and physical therapy helps restore function. Full recovery may take several months, with activity restrictions during the healing phase.

Complications

• Infection at the open fracture site.
• Nerve or blood vessel damage.
• Nonunion or malunion of the fracture.
• Chronic pain or limited shoulder mobility.
• Post-traumatic arthritis in the shoulder joint.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if at risk.
• 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, 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 care.

Tips for Medical Coders

Document the fracture as displaced, specify the left shoulder, and confirm the open nature of the injury. Include details about the initial encounter and any associated trauma. Ensure the open fracture is clearly differentiated from closed fractures in the medical record to support accurate coding.
