M93.211 Osteochondritis dissecans, right shoulder

Name of the Condition

• Osteochondritis dissecans, right shoulder

Summary

Osteochondritis dissecans is a joint condition where a segment of cartilage and the underlying bone lose blood supply and may detach. This can lead to pain, joint instability, and impaired movement. The right shoulder designation indicates the condition is localized to the right shoulder joint.

Causes

The exact cause is often unclear but may involve repetitive trauma, reduced blood flow to the bone, or abnormal bone development. Genetic factors or mechanical stress from activities can contribute to its development.

Risk Factors

• Participation in high-impact or repetitive-stress activities (e.g., sports)
• Adolescence or young adulthood
• Male gender (more commonly affected)
• Prior joint injury or surgery

Symptoms

• Joint pain, often during or after activity
• Swelling or tenderness around the affected joint
• Reduced range of motion
• A feeling of joint "giving way" or instability
• Clicking, locking, or catching sensations

Diagnosis

Diagnosis involves a physical examination to assess joint function and tenderness. Imaging tests, such as X-rays, MRI, or CT scans, are used to visualize bone and cartilage changes and determine the extent of the condition.

Treatment Options

• Rest and activity modification to reduce joint stress
• Physical therapy to improve strength and range of motion
• Immobilization with a sling or brace to promote healing
• Surgical intervention (e.g., fragment fixation or removal) for severe or unstable cases

Prognosis and Follow-Up

Prognosis depends on the size and stability of the lesion, as well as the patient's adherence to treatment. Regular follow-up with imaging and physical exams is often recommended to monitor healing and joint function.

Complications

• Persistent joint pain or instability
• Early-onset osteoarthritis
• Fragment detachment leading to loose bodies in the joint
• Limited range of motion

Lifestyle & Prevention

• Avoid repetitive overhead activities or sports that stress the shoulder
• Maintain shoulder strength and flexibility through targeted exercises
• Use proper form during physical activities to reduce injury risk
• Warm up and cool down adequately before and after exercise

When to Seek Professional Help

Seek care if you experience persistent shoulder pain, swelling, or a sudden decrease in range of motion. Immediate attention is needed if the joint locks, clicks, or feels unstable.

Tips for Medical Coders

Document the affected side (right shoulder) and any associated symptoms or findings. Ensure clinical notes support the diagnosis and specify whether the condition is active, stable, or requires intervention.
