S42.142 Displaced fracture of glenoid cavity of scapula, left shoulder

Name of the Condition

• Displaced fracture of glenoid cavity of scapula, left shoulder

Summary

A displaced fracture of the glenoid cavity of the scapula, left shoulder, 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.

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 and determine the degree of displacement. The location (left shoulder) and displacement are key factors in identifying the specific injury.

Treatment Options

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

Prognosis and Follow-Up

Prognosis varies based on the extent of the fracture and treatment. Most patients recover with proper care, though some may experience long-term stiffness or reduced mobility. Follow-up appointments are important to monitor healing, assess range of motion, and adjust rehabilitation plans as needed.

Complications

Potential complications include chronic pain, arthritis in the shoulder joint, nerve or blood vessel damage, or nonunion of the fracture. Infection or hardware-related issues may occur if surgery is performed.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Strengthening shoulder muscles and using proper protective gear during sports can reduce injury risk. Maintaining bone health through diet and exercise may also help prevent fractures.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., fever, redness). Persistent pain or limited mobility after initial treatment should also prompt a follow-up with a healthcare provider.

Tips for Medical Coders

Document the laterality (left shoulder) and displacement clearly in the medical record, as these are critical for accurate coding. Ensure the fracture is described as "displaced" to align with the code. Include details about the injury mechanism and any imaging findings to support the diagnosis.
