S42.151B Displaced fracture of neck of scapula, right shoulder, initial encounter for open fracture

Name of the Condition

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

Summary

A displaced fracture of the neck of the scapula involves a break in the narrow portion of the shoulder blade bone that connects the body of the scapula to the glenoid fossa (shoulder joint), with the bone fragments shifted out of their normal alignment. This is an open fracture, meaning the broken bone has pierced the skin, increasing the risk of infection. The injury affects the right shoulder and is classified as an initial encounter, indicating the first time the fracture is being treated.

Causes

Traumatic injury is the primary cause of this fracture. High-impact events, such as motor vehicle accidents, falls from a significant height, or direct blows to the shoulder or back, can result in a displaced fracture of the scapular neck. Open fractures occur when the force of the injury is severe enough to break the skin, exposing the bone.

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

• Severe 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 wound or open skin at the fracture site.
• Possible signs of infection, such as redness, warmth, or drainage.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and functional limitations. Imaging tests, such as X-rays, CT scans, or MRIs, are typically used to confirm the fracture, determine displacement, and evaluate the extent of the open wound. The open nature of the fracture may require additional assessment for infection or soft tissue damage.

Treatment Options

• Immediate wound care to clean and dress the open fracture site to reduce infection risk.
• Surgical intervention may be necessary to realign and stabilize the displaced bone fragments, often using plates, screws, or pins.
• Immobilization of the shoulder with a sling or brace to promote healing and protect the fracture.
• Pain management with medications like NSAIDs or acetaminophen.
• Antibiotics to prevent or treat infection, especially in open fractures.
• Physical therapy to restore range of motion and strength once the fracture begins to heal.

Prognosis and Follow-Up

The prognosis depends on the severity of the fracture, the success of treatment, and the presence of complications. Most patients recover with proper care, but recovery may take several months. Follow-up appointments are essential to monitor healing, assess for infection, and adjust treatment as needed. Physical therapy is often recommended to restore function.

Complications

• Infection at the open fracture site.
• Nerve or blood vessel damage near the fracture.
• Nonunion or malunion of the bone, where the fracture does not heal properly.
• Chronic pain or limited shoulder mobility.
• Post-traumatic arthritis in the shoulder joint.

Lifestyle & Prevention

• Avoid high-impact activities or contact sports until fully healed.
• Use protective gear during sports or activities with a risk of falls.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Engage in regular, low-impact exercise to strengthen muscles around the shoulder.

When to Seek Professional Help

Seek immediate medical attention if you experience severe shoulder pain, visible bone protrusion, or an open wound after an injury. Contact a healthcare provider if you notice signs of infection, such as increased redness, swelling, or fever, or if pain or mobility issues worsen during recovery.

Tips for Medical Coders

This code (S42.151B) is specific to a displaced fracture of the neck of the scapula on the right shoulder, classified as an initial encounter for an open fracture. Documentation should clearly indicate the fracture's location (neck of scapula), side (right), displacement, and the open nature of the injury. Ensure the encounter is labeled as "initial" to reflect the first treatment for this fracture.
