S43.312 Subluxation of left scapula

Name of the Condition

• Subluxation of Left Scapula

Summary

This condition involves a partial displacement of the left scapula, where the shoulder blade is not fully aligned with its normal position but remains in partial contact with surrounding structures. It typically results from trauma or injury and may cause pain, instability, or restricted movement in the shoulder area.

Causes

Traumatic events such as falls, direct blows to the shoulder, or forceful movements can cause subluxation of the scapula. Sports injuries, motor vehicle accidents, or falls are common triggers. Repetitive overhead activities or sudden forceful motions may also contribute to this injury.

Risk Factors

• Participation in contact sports or activities with high fall risk.
• Previous shoulder injuries or ligamentous instability.
• Age-related joint laxity or connective tissue disorders.
• Occupations requiring repetitive arm or shoulder movements.

Symptoms

• Pain and tenderness in the shoulder area.
• Limited range of motion or stiffness.
• Sensation of the shoulder feeling unstable or "popping out."
• Swelling or bruising around the injury site.

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and joint stability. Imaging studies like X-rays or MRIs may be used to confirm subluxation and rule out fractures or other injuries.

Treatment Options

Treatment may include rest, immobilization with a sling, pain management, and physical therapy to restore strength and mobility. Severe cases might require surgical intervention to stabilize the scapula.

Prognosis and Follow-Up

Most cases improve with conservative treatment, but recovery time varies. Follow-up care ensures proper healing and may involve ongoing therapy to prevent recurrence.

Complications

Potential complications include chronic instability, persistent pain, or nerve damage if the injury is not properly managed.

Lifestyle & Prevention

Avoid high-risk activities without proper protection. Strengthen shoulder muscles through targeted exercises and use proper form during repetitive movements to reduce injury risk.

When to Seek Professional Help

Seek care if pain is severe, movement is severely restricted, or symptoms worsen after initial injury. Immediate attention is needed for signs of nerve or vascular involvement.

Tips for Medical Coders

Document the laterality (left) and confirm the subluxation is not a complete dislocation. Ensure clinical notes specify the injury mechanism and any associated symptoms to support coding accuracy.
