S43.034 Inferior dislocation of right humerus

Name of the Condition

• Inferior Dislocation of Right Humerus

Summary

This condition involves the complete displacement of the right humerus (upper arm bone) from the glenoid fossa of the scapula, with the humeral head moving downward (inferiorly). It typically results from trauma or injury and may cause pain, instability, or restricted movement in the shoulder joint.

Causes

The primary cause is trauma, such as a fall, direct blow to the shoulder, or forceful movement that exceeds the joint's normal range of motion. Sports injuries, motor vehicle accidents, or falls are common triggers. Repetitive overhead activities or underlying joint instability may also contribute.

Risk Factors

• Participation in contact sports or activities with high shoulder strain.
• Previous shoulder dislocations or subluxations.
• Age-related joint laxity or connective tissue disorders.
• Occupations requiring repetitive overhead movements.

Symptoms

• Intense shoulder pain, especially with movement.
• Visible deformity or abnormal shoulder contour.
• Swelling, bruising, or tenderness around the joint.
• Limited range of motion or inability to move the arm.
• Sensation of the shoulder "popping out" or feeling unstable.

Diagnosis

Diagnosis begins with a clinical examination to assess pain, deformity, and range of motion. Imaging studies like X-rays or CT scans may be used to confirm the dislocation and rule out associated fractures or soft tissue damage.

Treatment Options

Treatment typically involves closed reduction to realign the humerus, followed by immobilization with a sling or brace. Physical therapy is often recommended to restore strength and mobility. Severe cases or those with recurrent dislocations may require surgical intervention.

Prognosis and Follow-Up

Prognosis is generally good with proper treatment, though some patients may experience residual stiffness or instability. Follow-up care includes monitoring for complications and gradual return to activity under medical guidance.

Complications

Potential complications include nerve or vascular injury, recurrent dislocation, chronic shoulder instability, or post-traumatic arthritis. Prompt treatment reduces these risks.

Lifestyle & Prevention

Avoid high-risk activities or use protective gear during sports. Strengthen shoulder muscles through targeted exercises and maintain flexibility to support joint stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe shoulder pain, visible deformity, inability to move the arm, or signs of nerve/vascular compromise (e.g., numbness, discoloration).

Tips for Medical Coders

Code S43.034 is specific to the inferior dislocation of the right humerus. Ensure documentation confirms the side (right) and type of dislocation (inferior) to support accurate coding. Note associated injuries or procedures for additional coding if applicable.
