Overview
Coccydynia, characterized by coccygeal pain exacerbated by sitting, can arise from various causes including trauma, anatomical variations, and less commonly, iatrogenic factors such as contraceptive device use 135.Diagnosis
Clinical Presentation: Pain localized to the coccyx, often worsened by sitting 12.
Imaging: MRI useful for identifying anatomical variations, masses (e.g., haemangioma), and other structural abnormalities 5.
Differential Diagnosis: Includes trauma, infections (e.g., osteomyelitis), and iatrogenic causes 235.Management
First-Line Treatments:
- Sitting Modifications: Use of coccygeal cushions to reduce pressure 1.
- Corticosteroid Injections: Local injections for pain relief 1.
Adjunctive Treatments:
- Physical Therapy: Exercises to strengthen surrounding musculature 2.
- Surgical Intervention: Considered if conservative measures fail, including excision or fusion procedures 14.Special Populations
Pregnancy: No specific guidelines provided; conservative management likely preferred 1.
Elderly: Conservative approaches favored due to increased surgical risks 14.
Comorbidities: Management tailored to individual patient characteristics and underlying causes 24.Key Recommendations
Initiate conservative management including pressure relief and corticosteroid injections for most cases (Evidence: Moderate 1).
Consider imaging (MRI) to rule out structural abnormalities or masses contributing to pain (Evidence: Moderate 5).
Evaluate for surgical intervention if conservative treatments fail over an appropriate timeframe (Evidence: Expert opinion 14).References
