S42.153S Displaced fracture of neck of scapula, unspecified shoulder, sequela

Name of the Condition

• Displaced fracture of neck of scapula, unspecified shoulder, sequela

Summary

A displaced fracture of the neck of the scapula, unspecified shoulder, sequela, refers to a break in the narrow portion of the shoulder blade bone that connects to the shoulder joint, with bone fragments shifted out of their normal alignment. This condition is a late effect (sequela) of the initial injury, meaning it represents the residual state after the acute phase has resolved. The sequela may involve persistent instability, limited function, or other long-term consequences affecting the shoulder. Displacement occurs when the force of the original injury was sufficient to move the bone fragments from their anatomical position, and the sequela reflects the ongoing impact on shoulder stability and mobility.

Causes

The sequela arises from a prior traumatic injury to the scapular neck, such as a motor vehicle accident, fall from height, or direct blow to the shoulder or back. The initial fracture displaced the bone fragments, and the sequela represents the chronic state resulting from incomplete healing, malunion, or persistent instability. The unspecified shoulder indicates the side affected was not documented during the acute phase or is not relevant to the sequela description.

Risk Factors

• Prior history of scapular neck fracture or shoulder trauma.
• Inadequate initial treatment or nonunion of the original fracture.
• Underlying conditions affecting bone healing, such as osteoporosis or diabetes.
• Advanced age, which may impair recovery and increase the risk of long-term complications.

Symptoms

• Chronic pain in the shoulder or upper back, often with movement.
• Reduced range of motion or stiffness in the shoulder.
• Persistent swelling or tenderness over the scapular area.
• Visible deformity or asymmetry in shoulder alignment.
• Weakness or instability during shoulder use.

Diagnosis

Diagnosis of the sequela involves a clinical evaluation of the patient's history, including the original injury and treatment. Physical examination assesses shoulder function, range of motion, and stability. Imaging studies, such as X-rays or CT scans, may be used to visualize the residual displacement, malunion, or associated changes in bone structure. The sequela is confirmed by correlating the current findings with the prior fracture and ruling out acute injury.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to restore mobility and strength, pain management with medications or injections, and, in some cases, surgical intervention to correct residual displacement or stabilize the joint. Bracing or activity modification may be recommended to support healing and prevent further injury.

Prognosis and Follow-Up

Prognosis depends on the severity of the original injury, the degree of residual displacement, and the effectiveness of treatment. Most patients experience improved function with therapy, though some may have persistent limitations. Follow-up care involves regular monitoring of shoulder function and imaging to assess healing. Long-term management may be necessary for chronic pain or instability.

Complications

• Chronic pain or discomfort.
• Persistent shoulder instability or weakness.
• Limited range of motion or stiffness.
• Post-traumatic arthritis due to joint damage.
• Nerve or vascular injury from the original trauma, leading to ongoing symptoms.

Lifestyle & Prevention

• Engage in regular, low-impact exercises to maintain shoulder strength and flexibility.
• Avoid activities that place excessive stress on the shoulder, such as heavy lifting or contact sports.
• Use proper body mechanics to reduce injury risk during daily tasks.
• Maintain bone health through a balanced diet and, if appropriate, supplements to support healing.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or a sudden decrease in shoulder function. Prompt evaluation is necessary if you notice signs of infection (e.g., redness, fever) or if the shoulder becomes increasingly unstable.

Tips for Medical Coders

This code is used for the sequela of a displaced scapular neck fracture, unspecified shoulder. Document the relationship to the original injury, including the time elapsed since the acute event and any residual symptoms or functional limitations. Ensure the sequela is clearly distinguished from acute fracture codes and that the unspecified shoulder is appropriately documented if the side was not specified during the acute phase.
