S42.145 Nondisplaced fracture of glenoid cavity of scapula, left shoulder

Name of the Condition

• Nondisplaced fracture of glenoid cavity of scapula, left shoulder

Summary

A nondisplaced 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 remain in their normal anatomical position. This condition involves damage to the glenoid, a shallow, concave structure that forms part of the shoulder joint. Nondisplaced fractures typically preserve joint alignment and may have a more favorable prognosis compared to displaced fractures.

Causes

Traumatic injury is the primary cause of glenoid cavity fractures. Common mechanisms include falls onto an outstretched arm, direct blows to the shoulder, or high-impact events such as motor vehicle accidents. Sports-related collisions or forceful impacts during physical activities may also result in this type of fracture. The left shoulder is often affected due to its exposure in certain injury scenarios.

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 injuries that affect bone integrity.

Symptoms

• Pain in the shoulder or upper back, especially with movement.
• Swelling, bruising, or tenderness over the shoulder joint.
• Limited range of motion in the shoulder.
• Difficulty lifting or rotating the arm.
• In severe cases, joint instability or visible deformity.

Diagnosis

Diagnosis begins with a thorough clinical evaluation, including a detailed patient history and 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 if it is nondisplaced. These tests help visualize the bone structure and ensure no displacement or associated injuries are present.

Treatment Options

Treatment for a nondisplaced fracture of the glenoid cavity often involves conservative management, such as immobilization with a sling to support the shoulder and allow healing. Pain management may include over-the-counter or prescription medications. Physical therapy is usually recommended after initial healing to restore strength and mobility. In rare cases, surgical intervention may be considered if there are complications or associated injuries.

Prognosis and Follow-Up

The prognosis for a nondisplaced glenoid cavity fracture is generally good, with most patients recovering fully with appropriate treatment. Follow-up care typically includes regular monitoring to ensure proper healing and gradual return to normal activities. Physical therapy may be necessary to regain full shoulder function, and imaging studies may be repeated to confirm healing progress.

Complications

While uncommon, complications can include chronic pain, limited shoulder mobility, or post-traumatic arthritis. Infection or nerve damage may occur in rare cases, particularly if surgical intervention is required. Early diagnosis and adherence to treatment plans can help minimize these risks.

Lifestyle & Prevention

To reduce the risk of shoulder fractures, individuals should engage in regular exercise to strengthen shoulder muscles and bones. Using proper protective gear during sports or high-risk activities can help prevent injuries. Maintaining bone health through a balanced diet rich in calcium and vitamin D may also lower fracture risk, especially in older adults.

When to Seek Professional Help

Seek medical attention if you experience severe shoulder pain, swelling, or difficulty moving the arm after an injury. Persistent pain, numbness, or signs of infection, such as redness or fever, should also prompt a visit to a healthcare provider. Early evaluation is important to ensure proper diagnosis and treatment.

Tips for Medical Coders

When coding for a nondisplaced fracture of the glenoid cavity of the scapula, left shoulder, use the ICD-10-CM code S42.145. Ensure documentation specifies the fracture is nondisplaced and involves the left shoulder. Include details about the mechanism of injury, clinical findings, and any imaging results to support the diagnosis. Verify that the code aligns with the anatomical location and fracture type described in the medical record.
