S42.144 Nondisplaced fracture of glenoid cavity of scapula, right shoulder

Name of the Condition

• Nondisplaced fracture of glenoid cavity of scapula, right shoulder

Summary

A nondisplaced fracture of the glenoid cavity of the scapula, right 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 alignment. This condition involves damage to the glenoid, a shallow, concave structure that forms part of the shoulder joint. Nondisplaced fractures typically preserve joint stability and may have a lower risk of immediate functional impairment compared to displaced fractures.

Causes

Traumatic injury is the primary cause of this fracture. 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 trauma must be sufficient to cause a fracture but not severe enough to displace the bone fragments.

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 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 if it is nondisplaced. These tests help visualize the bone alignment and rule out associated injuries to the shoulder joint or surrounding structures.

Treatment Options

Treatment for a nondisplaced fracture 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 some cases, surgical intervention may be considered if there are concerns about joint stability or if the fracture does not heal properly.

Prognosis and Follow-Up

The prognosis for a nondisplaced fracture of the glenoid cavity is generally favorable, with most patients recovering full function over time. Follow-up care typically includes regular monitoring to ensure proper healing and may involve repeat imaging to assess bone alignment. Physical therapy is often a key component of recovery to restore shoulder strength and range of motion. Most patients can return to normal activities within several weeks to months, depending on the severity of the injury.

Complications

While nondisplaced fractures have a lower risk of complications, potential issues can include delayed healing, persistent pain, or reduced shoulder mobility. In rare cases, arthritis or joint instability may develop if the fracture affects the joint surface. Early intervention and adherence to treatment plans can help minimize these risks.

Lifestyle & Prevention

To reduce the risk of fractures, individuals should engage in regular exercise to maintain bone strength and muscle support around the shoulder. Wearing protective gear during contact sports or high-risk activities can help prevent traumatic injuries. Avoiding falls by using assistive devices, such as handrails, and maintaining a safe home environment is also important, especially for older adults.

When to Seek Professional Help

Seek medical attention if you experience severe shoulder pain, inability to move the arm, visible deformity, or signs of infection, such as fever or increased swelling. Prompt evaluation is necessary to rule out more serious injuries and ensure appropriate treatment.

Tips for Medical Coders

When coding for a nondisplaced fracture of the glenoid cavity of the scapula, right shoulder, use the ICD-10-CM code S42.144. Ensure documentation specifies the fracture is nondisplaced and involves the right 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.
