M84.350 Stress fracture, pelvis

Name of the Condition

• Stress Fracture, Pelvis

Summary

A stress fracture of the pelvis is a small crack or severe bruising within a pelvic bone, typically resulting from repetitive force or overuse. This injury occurs when the bone's ability to repair itself is exceeded by mechanical stress, often affecting weight-bearing areas of the pelvis.

Causes

Stress fractures develop due to repeated mechanical stress on a pelvic bone that outpaces its natural repair process. Common causes include increased physical activity, improper training techniques, and inadequate rest between activities.

Risk Factors

• Participation in high-impact sports (e.g., running, soccer)
• Sudden increase in physical activity level
• Poor nutrition, including insufficient calcium or vitamin D
• Low bone density or osteoporosis
• Overuse from repetitive pelvic motions (e.g., long-distance running)

Symptoms

• Pain in the pelvic region that worsens with activity
• Swelling and tenderness around the fracture site
• Pain that diminishes with rest
• Difficulty with weight-bearing activities (e.g., walking, climbing stairs)

Diagnosis

Diagnosis involves a physical examination by a healthcare provider, followed by imaging tests such as X-rays, MRI, or bone scans to confirm the fracture. Early stress fractures may not be visible on standard X-rays.

Treatment Options

• Rest and avoiding activities that exacerbate the injury
• Ice application to reduce swelling and pain
• Protective measures (e.g., crutches, pelvic bracing) to stabilize the area
• Gradual return to activity with proper conditioning
• Pain management as needed

Prognosis and Follow-Up

Most stress fractures of the pelvis heal with appropriate rest and treatment, typically within 6–8 weeks. Follow-up care may include monitoring for healing progress and gradual resumption of activity to prevent recurrence.

Complications

• Delayed healing or nonunion if not properly managed
• Progression to a complete fracture with continued activity
• Chronic pain or functional limitations

Lifestyle & Prevention

• Gradually increase physical activity to avoid overuse
• Ensure adequate nutrition, including calcium and vitamin D
• Use proper footwear and training techniques
• Incorporate rest days into exercise routines
• Address underlying bone density issues if present

When to Seek Professional Help

Seek medical attention if pain persists despite rest, worsens, or is accompanied by swelling, bruising, or difficulty bearing weight.

Tips for Medical Coders

Document the specific location (pelvis) and any contributing factors (e.g., activity level, underlying conditions) to support accurate coding. Ensure clinical documentation aligns with the diagnosis and treatment provided.
