Management of Coccyx Pain in Adults
Start with conservative therapy including NSAIDs, a coccyx cushion with a cutout, and pelvic floor physical therapy, as this approach successfully resolves symptoms in the majority of patients without requiring invasive interventions. 1, 2
Initial Diagnostic Approach
Obtain dynamic lateral radiographs of the coccyx in both standing and sitting positions to identify abnormal mobility (hypermobility, subluxation, or luxation), which is the most common pathological finding in 70% of coccygodynia patients. 3 This imaging is the gold standard for diagnosis. 1, 2
Key Clinical Features to Assess
- Pain location: Midline pain directly on the lowest coccyx segment, below the sacrum and above the anus 4
- Pain pattern: Worse with sitting and intensified during position changes (sitting to standing) 1, 2, 4
- Trauma history: Only 50% of cases have identifiable trauma as a trigger 1, 2
- Physical examination: Focal tenderness during direct palpation of the coccyx 4
Rule Out Alternative Diagnoses
Exclude extracoccygeal causes including pilonidal cyst, perianal abscess, hemorrhoids, pelvic organ disease, lumbosacral spine disorders, sacroiliac joint problems, and piriformis muscle dysfunction. 3 Note that 30% of cases remain idiopathic despite thorough evaluation. 3
First-Line Conservative Treatment
Core Conservative Interventions
- Oral NSAIDs for pain control 1, 2
- Coccyx cushion with a recess/cutout to relieve pressure while sitting 1, 2
- Pelvic floor physical therapy focused on muscle relaxation, with mean treatment duration of 9 sessions 5
Pelvic floor physical therapy is particularly effective, reducing average pain scores from 5.08 to 1.91 (P < .001) and achieving 71.9% mean global improvement in patients who completed treatment. 5 This approach is safe and effective even in postcoccygectomy patients with persistent pain. 5
Additional Conservative Options
- Local infiltrations with glucocorticoid and local anesthetic directly into the painful area 1, 2
- Baclofen for muscle relaxation (used in 19% of patients in one series) 5
- Ganglion impar blocks (8% of patients) or coccygeus trigger point injections (17% of patients) 5
- Manual therapy including massage and stretching of the levator ani muscle, and mobilization of the coccyx 3
When to Consider Surgical Intervention
Reserve coccygectomy for refractory cases that fail conservative therapy for more than 6 months. 1, 2 Surgery achieves 80-90% success rates when indications are correct. 1, 2
Best Surgical Candidates
Patients with abnormal mobility of the coccyx and bony spicules respond best to surgical treatment (partial or total coccygectomy). 3 These anatomic abnormalities can be confirmed on dynamic radiographs. 3
Common Pitfalls to Avoid
- Don't dismiss the diagnosis: Coccygodynia patients are frequently underestimated and undergo prolonged suffering without proper diagnosis. 1, 2
- Don't rush to surgery: The majority of patients achieve satisfactory results with conservative modalities. 3
- Don't skip dynamic imaging: Static radiographs miss the most common pathology (abnormal mobility). 3, 1, 2
- Don't overlook pelvic floor dysfunction: Physical therapy targeting pelvic floor muscle relaxation is highly effective but often not considered. 5
Treatment Algorithm
- Confirm diagnosis with dynamic lateral radiographs (standing and sitting) 1, 2
- Initiate conservative therapy with NSAIDs, coccyx cushion, and pelvic floor physical therapy 1, 2, 5
- Add local injections if inadequate response after 4-6 weeks 1, 2
- Consider coccygectomy only after 6 months of failed conservative treatment, particularly in patients with documented abnormal mobility or spicules 3, 1, 2
Greater initial pain scores and history of previous injections correlate with higher pain scores at treatment completion, but pain duration and trauma history do not affect outcomes. 5 Women are affected four times more frequently than men. 1, 2
