M21.212 Flexion deformity, left shoulder

Name of the Condition

• Flexion deformity, left shoulder

Summary

Flexion deformity of the left shoulder is a condition where the left shoulder joint is persistently bent forward, limiting its ability to fully extend. This reduces the normal range of motion and may lead to functional impairment or discomfort, depending on the severity.

Causes

Flexion deformity of the left shoulder can result from prolonged immobility, such as after surgery or injury, or from underlying conditions like arthritis, neuromuscular disorders, or contractures. Trauma, abnormal muscle or tendon tightness, or postural habits may also contribute to its development.

Risk Factors

• Age-related joint degeneration
• History of left shoulder injuries or surgeries
• Chronic conditions affecting muscles or nerves
• Prolonged bed rest or immobilization
• Genetic predisposition to musculoskeletal issues

Symptoms

• Persistent forward bending of the left shoulder joint
• Difficulty fully extending the left arm backward
• Pain or stiffness in the left shoulder area
• Reduced mobility or functional limitations

Diagnosis

Diagnosis involves a physical examination to assess joint mobility and range of motion. Imaging tests, such as X-rays or MRI, may be used to evaluate bone or soft tissue structures. Clinical history and underlying conditions are also considered.

Treatment Options

• Physical therapy to improve joint mobility and strength
• Use of braces or orthotic devices
• Medications for pain or inflammation
• Surgical intervention in severe cases

Prognosis and Follow-Up

Prognosis depends on the underlying cause and severity. Early intervention often improves outcomes. Follow-up may include regular monitoring of range of motion and functional status, with adjustments to treatment as needed.

Complications

• Chronic pain
• Reduced shoulder function
• Difficulty with daily activities
• Potential for secondary joint damage

Lifestyle & Prevention

• Maintain regular shoulder exercises to preserve mobility
• Avoid prolonged immobility or poor posture
• Manage underlying conditions like arthritis
• Use proper techniques during physical activities

When to Seek Professional Help

Seek medical attention if you experience persistent shoulder stiffness, pain, or difficulty moving the left arm, especially after injury or surgery.

Tips for Medical Coders

Document the specific side (left shoulder) and confirm the deformity is flexion-related. Ensure clinical notes support the diagnosis and specify any contributing factors, such as trauma or immobility, to justify code assignment.
