S42.153A Displaced fracture of neck of scapula, unspecified shoulder, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of neck of scapula, unspecified shoulder, initial encounter for closed fracture

Summary

A displaced fracture of the neck of the scapula, unspecified shoulder, refers to a break in the narrow portion of the shoulder blade bone that connects to the shoulder joint, with the bone fragments shifted out of their normal alignment. This condition affects the shoulder (unspecified side) and may impact shoulder stability and function due to the neck's role in supporting the glenoid fossa. The fracture is closed (skin intact) and is the initial encounter for treatment. Displacement occurs when the force of injury is sufficient to move the bone fragments from their anatomical position.

Causes

Traumatic injury is the primary cause of this fracture. Common mechanisms include falls, 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 displacement of the bone fragments. The unspecified shoulder may be affected due to the direction of impact or body positioning during the injury.

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, visible deformity or instability.

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 evaluate displacement. Additional imaging, such as CT scans, may be ordered if further detail is needed to assess fragment alignment or associated injuries. The closed nature of the fracture is confirmed by the absence of skin penetration.

Treatment Options

Treatment depends on the severity of displacement and patient factors. Non-displaced or minimally displaced fractures may be managed with immobilization (e.g., sling) and pain control. Displaced fractures may require surgical intervention to realign and stabilize the bone fragments, often using plates or screws. Physical therapy is typically recommended during recovery to restore strength and mobility.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time varies based on fracture severity and treatment approach. Most patients regain full shoulder function, but some may experience residual stiffness or weakness. Follow-up appointments are necessary to monitor healing, assess range of motion, and adjust rehabilitation plans. Imaging may be repeated to confirm proper bone alignment.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), chronic pain, or shoulder instability. Nerve or vascular injury near the fracture site is rare but possible. Infection risk is low for closed fractures but may increase with surgical intervention.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Strengthen shoulder and upper back muscles to improve stability. Use protective gear during contact sports. Maintain bone health through adequate calcium and vitamin D intake, especially for those with osteoporosis. Fall prevention strategies (e.g., home modifications) are important for older adults.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, redness, drainage). Follow up with a healthcare provider if pain worsens, swelling persists, or mobility does not improve with treatment.

Tips for Medical Coders

Code S42.153A is used for a displaced fracture of the scapular neck, unspecified shoulder, initial encounter for closed fracture. Document the fracture's displacement, side (unspecified), and that it is closed. Include details on the initial encounter (e.g., no prior treatment for this fracture) to support accurate coding. Ensure alignment with clinical documentation to reflect the fracture's characteristics and treatment context.
