S42.135 Nondisplaced fracture of coracoid process, left shoulder

Name of the Condition

• Nondisplaced fracture of coracoid process, left shoulder

Summary

A nondisplaced fracture of the coracoid process is a break in the small hook-like projection of the scapula (shoulder blade) where the bone fragments remain in their normal anatomical position. This condition affects the left shoulder and is classified as nondisplaced, meaning the fracture does not involve significant misalignment of the bone. The coracoid process is located near the shoulder joint and can be injured by direct trauma or forceful movements.

Causes

Traumatic injury is the primary cause of coracoid process fractures. Common mechanisms include falls onto the shoulder, direct blows to the area, or forceful muscle contractions during activities like weightlifting or sports. High-impact events, such as motor vehicle accidents, may also result in this type of fracture.

Risk Factors

• Participation in contact sports or activities with a high risk of shoulder trauma.
• Osteoporosis or other bone-weakening conditions.
• Previous shoulder injuries that may weaken the area.
• Advanced age, which can increase susceptibility to fractures from minor trauma.

Symptoms

• Pain in the shoulder, particularly when moving the arm or pressing on the coracoid process.
• Swelling and tenderness over the affected area.
• Limited range of motion in the shoulder joint.
• Difficulty lifting or rotating the arm.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and functional limitations. Imaging tests, such as X-rays or CT scans, are typically used to confirm the fracture and evaluate the degree of displacement. The nondisplaced nature of the fracture is confirmed by the alignment of the bone fragments on imaging.

Treatment Options

• Immobilization using a sling or brace to support the shoulder and allow healing.
• Pain management with over-the-counter or prescription medications.
• Physical therapy to restore range of motion and strength once healing progresses.
• Surgical intervention is rarely required for nondisplaced fractures unless other complications arise.

Prognosis and Follow-Up

Most nondisplaced fractures of the coracoid process heal well with conservative treatment. Recovery typically takes 6 to 8 weeks, during which follow-up appointments may be scheduled to monitor healing. Physical therapy is often recommended to restore full function. Long-term outcomes are generally favorable, with most patients regaining normal shoulder mobility.

Complications

• Delayed union or nonunion of the fracture, though rare.
• Persistent pain or stiffness in the shoulder.
• Nerve or blood vessel injury in severe cases.
• Post-traumatic arthritis if the joint is affected.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper protective gear during sports or physical activities.
• Maintain bone health through a balanced diet and regular exercise.
• Fall prevention strategies, such as home modifications, for older adults.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or inability to move the shoulder after an injury. Immediate care is also recommended if you notice numbness, tingling, or changes in skin color, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

Document the specific location (left shoulder) and fracture type (nondisplaced) to ensure accurate coding. Include details about the mechanism of injury, imaging findings, and treatment plan to support the diagnosis. Verify that the code aligns with the clinical documentation and any applicable guidelines for fracture classification.
