S42.143A Displaced fracture of glenoid cavity of scapula, unspecified shoulder, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of glenoid cavity of scapula, unspecified shoulder, initial encounter for closed fracture

Summary

A displaced fracture of the glenoid cavity of the scapula, unspecified shoulder, initial encounter for closed fracture, refers to a break in the socket portion of the shoulder blade that articulates with the humerus, where the bone fragments are not aligned. 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. The "unspecified shoulder" designation means the side is not documented, and "initial encounter for closed fracture" specifies this is the first treatment for a fracture without an open wound.

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.

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 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.
• In severe cases, joint instability or visible deformity.

Diagnosis

Diagnosis begins with a clinical evaluation, including a 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 rule out associated injuries. The "closed fracture" status is determined by the absence of an open wound or communication with the fracture site.

Treatment Options

Treatment depends on the severity of displacement and patient factors. Non-surgical management may include immobilization with a sling, pain management, and physical therapy. Surgical intervention, such as open reduction and internal fixation, may be necessary for significantly displaced fractures to restore joint alignment and stability.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and patient compliance with rehabilitation. Most patients recover function with appropriate treatment, but some may experience residual stiffness or weakness. Follow-up appointments monitor healing, assess range of motion, and adjust therapy as needed.

Complications

Potential complications include nonunion or malunion of the fracture, chronic shoulder pain, limited mobility, nerve or blood vessel injury, and post-traumatic arthritis. Infection is rare but possible if surgical intervention is required.

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 overexertion or improper lifting techniques that strain the shoulder.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to move the shoulder, visible deformity, or signs of infection (e.g., fever, redness, drainage). Persistent pain or limited mobility after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the side (unspecified) and encounter type (initial for closed fracture) clearly. Ensure clinical notes specify "displaced" to justify the code. Verify that no open wound or surgical intervention is documented, as this would change the code.
