S42.153B Displaced fracture of neck of scapula, unspecified shoulder, initial encounter for open fracture

Name of the Condition

• Displaced fracture of neck of scapula, unspecified shoulder, initial encounter for open fracture

Summary

A displaced fracture of the neck of the scapula, unspecified shoulder, initial encounter for open fracture, involves a break in the narrow portion of the shoulder blade bone connecting to the shoulder joint, with bone fragments shifted out of alignment. The fracture is open (compound), meaning the bone has pierced the skin, and this is the initial encounter for treatment. This condition affects shoulder stability and function due to the neck's role in supporting the glenoid fossa.

Causes

Traumatic injury is the primary cause. Common mechanisms include high-impact events such as motor vehicle accidents, falls from a significant height, or direct blows to the shoulder or back. Sports-related collisions or forceful impacts during physical activities may also result in this type of fracture. The open nature of the fracture indicates the force was sufficient to break the skin.

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

• Pain in the shoulder or upper back, especially 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 open wound or bone protrusion at the fracture site.
• In severe cases, visible deformity or instability.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and open wound presence. Imaging studies, such as X-rays or CT scans, confirm the fracture type, displacement, and open nature. The open wound is evaluated for contamination or infection risk. Additional tests may assess surrounding tissue or nerve damage.

Treatment Options

Treatment focuses on stabilizing the fracture and managing the open wound. This may include wound cleaning, antibiotics to prevent infection, and immobilization with a sling or brace. Surgical intervention may be needed to realign and fixate displaced fragments. Pain management and physical therapy support recovery once initial healing occurs.

Prognosis and Follow-Up

Prognosis depends on fracture severity, treatment response, and absence of complications. Most patients recover function with proper care, though open fractures carry higher infection risk. Follow-up includes monitoring wound healing, imaging to assess bone union, and gradual rehabilitation to restore shoulder mobility and strength.

Complications

• Infection at the open wound site.
• Delayed or improper bone healing (nonunion or malunion).
• Nerve or blood vessel damage near the fracture.
• Chronic pain or reduced shoulder function.
• Post-traumatic arthritis in the shoulder joint.

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 balance is impaired.
• Follow safety protocols in high-risk environments (e.g., construction sites).

When to Seek Professional Help

Seek immediate medical attention if you experience severe shoulder pain, visible bone or wound, inability to move the arm, or signs of infection (e.g., fever, increasing redness). Open fractures require urgent care to reduce infection risk.

Tips for Medical Coders

Document the fracture as displaced, open, and specify the initial encounter. Note the unspecified shoulder and confirm the open nature of the fracture. Ensure documentation supports the displacement and open wound to justify the code. Include details on treatment provided during the initial encounter.
