Name of the Condition

  • Stress Fracture, Pelvis and Femur

Summary

A stress fracture of the pelvis and femur is a small crack or severe bruising within the pelvic or femoral bones, 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 structures.

Causes

Stress fractures develop due to repeated mechanical stress on the pelvis or femur that outpaces the bone's 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, jumping)
  • Sudden increase in physical activity level
  • Poor nutrition, including insufficient calcium or vitamin D
  • Low bone density or osteoporosis
  • Overuse from repetitive weight-bearing motions

Symptoms

  • Pain in the hip, groin, or thigh that worsens with activity
  • Swelling and tenderness around the fracture site
  • Pain that diminishes with rest
  • Difficulty bearing weight on the affected leg

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 bracing or crutches to stabilize the area
  • Gradual return to activity with proper conditioning
  • Pain management as needed

Prognosis and Follow-Up

Most stress fractures heal with appropriate rest and treatment, though recovery time varies. 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 if left untreated

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

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 site (pelvis or femur) and any contributing factors, such as activity level or underlying conditions, to support accurate coding. Ensure clinical documentation aligns with the ICD-10-CM code M84.35.
