S43.132S Dislocation of left acromioclavicular joint, greater than 200% displacement, sequela

Name of the Condition

• Dislocation of Left Acromioclavicular Joint, Greater Than 200% Displacement, Sequela

Summary

This condition represents a sequela of a previously dislocated left acromioclavicular (AC) joint, where the clavicle remains displaced from the acromion of the scapula by more than 200%. It reflects the residual effects of the initial injury, which may include persistent pain, instability, or functional limitations in the shoulder.

Causes

The sequela arises from a prior traumatic event, such as a fall, direct blow to the shoulder, or forceful movement, that caused the original dislocation. The initial injury typically involved significant force, leading to complete separation of the AC joint.

Risk Factors

• History of shoulder trauma or ligamentous injury.
• Participation in contact sports or activities with high fall risk.
• Age-related degeneration or connective tissue disorders.
• Occupations requiring repetitive arm or shoulder movements.

Symptoms

• Chronic pain or discomfort around the top of the shoulder.
• Visible deformity or persistent swelling over the AC joint.
• Limited range of motion or instability in the shoulder.
• Sensation of the joint feeling "loose" or prone to dislocation.

Diagnosis

Diagnosis involves a physical examination to assess residual tenderness, deformity, and functional limitations. Imaging tests, such as X-rays, may be used to confirm the extent of displacement and rule out other complications. Documentation of the prior injury and its timeline is essential.

Treatment Options

• Conservative management, including physical therapy to improve strength and stability.
• Pain management with medications or injections.
• Surgical intervention in cases of severe instability or persistent symptoms.
• Activity modification to avoid aggravating movements.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the effectiveness of treatment. Regular follow-up may be necessary to monitor for complications or functional recovery. Long-term outcomes can include residual stiffness or occasional discomfort.

Complications

• Chronic shoulder instability or recurrent dislocation.
• Persistent pain or reduced range of motion.
• Degenerative changes in the AC joint over time.
• Nerve or vascular injury in rare cases.

Lifestyle & Prevention

• Avoid high-impact activities that stress the shoulder.
• Use proper protective gear during sports or physical work.
• Engage in regular shoulder-strengthening exercises to improve stability.
• Seek prompt evaluation for shoulder injuries to prevent long-term sequelae.

When to Seek Professional Help

Consult a healthcare provider if you experience worsening pain, new deformity, or loss of shoulder function. Immediate care is needed for signs of acute injury or if the joint feels unstable.

Tips for Medical Coders

Document the sequela status clearly, noting the prior dislocation and its timeline. Ensure the code S43.132S is used only when the condition is a direct result of a previous injury. Include details about the residual effects, such as persistent instability or functional limitations, to support the sequela designation.
