S42.116 Nondisplaced fracture of body of scapula, unspecified shoulder

Name of the Condition

• Nondisplaced fracture of body of scapula, unspecified shoulder

Summary

A nondisplaced fracture of the body of the scapula refers to a break in the main, central portion of the shoulder blade bone where the fractured fragments remain in their normal anatomical alignment. This condition involves damage to the scapula's body, the largest and most robust part of the bone, connecting the shoulder to the trunk. Nondisplaced fractures typically result from trauma and may cause pain and functional impairment, though the bone fragments stay in place without significant shifting.

Causes

Traumatic injury is the primary cause of nondisplaced fractures to the scapula's body. Common mechanisms include high-impact events such as motor vehicle accidents, falls from a significant height, or direct blows to the shoulder or back. Sports-related collisions or forceful impacts during physical activities may also result in this type of fracture, where the bone breaks but does not displace.

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

• 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, visible deformity or instability.

Diagnosis

Diagnosis begins with 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 verify that it is nondisplaced. The healthcare provider will evaluate the alignment of the bone fragments and rule out associated injuries to surrounding structures like the ribs or shoulder joint.

Treatment Options

Treatment for a nondisplaced fracture of the scapula's body often involves conservative management. This may include immobilization with a sling to support the arm, pain relief medications, and physical therapy to restore strength and mobility. Severe or complex cases may require surgical intervention, though nondisplaced fractures typically heal without surgery.

Prognosis and Follow-Up

The prognosis for a nondisplaced fracture of the scapula's body is generally favorable, with most patients recovering fully over several weeks to months. Follow-up care includes monitoring healing progress through imaging and physical therapy to ensure proper recovery. Complications are rare but may include chronic pain or reduced shoulder function if not managed appropriately.

Complications

• Chronic pain or discomfort in the shoulder or upper back.
• Reduced range of motion or stiffness in the shoulder joint.
• Potential for delayed union or nonunion of the fracture.
• Rarely, nerve or blood vessel damage affecting the arm.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid falls by using assistive devices if needed, especially in older adults.
• Engage in regular exercise to strengthen shoulder and back muscles.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or deformity after a shoulder or back injury. Immediate care is also recommended if you have difficulty moving your arm, numbness, or tingling, as these may indicate complications requiring prompt evaluation.

Tips for Medical Coders

When coding for S42.116, ensure the documentation specifies a nondisplaced fracture of the scapula's body with an unspecified shoulder. Verify that the fracture is not displaced and that no additional details (e.g., laterality or open/closed status) are provided, as these would require different codes. Confirm the injury is isolated to the scapula's body and not associated with other fractures or complications to avoid miscoding.
