S42.116A Nondisplaced fracture of body of scapula, unspecified shoulder, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of body of scapula, unspecified shoulder, initial encounter for closed fracture

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 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. The fracture is closed (skin intact) and occurs during the initial encounter for treatment. Nondisplaced fractures typically result from trauma and may cause pain and functional impairment, though the lack of displacement often allows for conservative management.

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. The force of the injury is sufficient to break the bone but not enough to displace the 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 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 (less common with nondisplaced fractures).

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and range of motion. Imaging studies, typically X-rays, are used to confirm the fracture and verify that it is nondisplaced. Additional imaging, such as CT scans, may be ordered if the fracture is complex or if other injuries are suspected. The closed nature of the fracture is confirmed by the absence of an open wound.

Treatment Options

Treatment for nondisplaced scapular fractures often involves conservative management, including rest, ice, and pain relief. Immobilization with a sling may be recommended to support the shoulder and promote healing. Physical therapy is typically introduced once initial pain subsides to restore strength and range of motion. Surgical intervention is rarely needed for nondisplaced fractures unless other complications arise.

Prognosis and Follow-Up

The prognosis for nondisplaced scapular fractures is generally favorable, with most patients recovering fully within 6 to 12 weeks. Follow-up appointments monitor healing progress, often with repeat imaging to confirm bone union. Physical therapy may continue to address residual stiffness or weakness. Long-term outcomes are typically good, with most patients regaining full shoulder function.

Complications

While rare, complications can include nonunion (failure to heal), malunion (healing in an abnormal position), or persistent pain. Nerve or blood vessel injury near the scapula is possible but uncommon. In some cases, arthritis or chronic shoulder instability may develop, particularly if the fracture affects joint surfaces.

Lifestyle & Prevention

To reduce the risk of scapular fractures, avoid high-impact activities without proper protection. Maintain bone health through a balanced diet rich in calcium and vitamin D, and engage in weight-bearing exercise to strengthen bones. Use protective gear during contact sports or activities with fall risks. If osteoporosis is present, work with a healthcare provider to manage bone density.

When to Seek Professional Help

Seek immediate medical attention if you experience severe shoulder pain after a fall or accident, especially if accompanied by swelling, bruising, or inability to move the arm. Contact a healthcare provider if pain persists beyond a few days, worsens, or is accompanied by numbness, tingling, or visible deformity.

Tips for Medical Coders

When coding S42.116A, ensure the documentation specifies a nondisplaced fracture of the scapula's body, an unspecified shoulder, and an initial encounter for a closed fracture. Verify that the fracture is not displaced and that the encounter is the first for this injury. Confirm the absence of open wounds or complications to justify the "closed" and "initial encounter" descriptors.
