What Is a Coccygectomy?
Coccygectomy involves careful removal of the tailbone to eliminate the source of chronic coccydynia.
A coccygectomy is the surgical excision (removal) of the coccyx, commonly known as the tailbone. This small triangular bone at the base of the spine consists of 3-5 fused vertebrae and serves as an attachment point for pelvic floor muscles, gluteal muscles, and several important ligaments.
Why Remove the Coccyx?
The coccyx is not essential for normal function. While it provides some support for pelvic floor muscles and serves as a weight-bearing structure when sitting, humans can function normally without it. The primary indication for removal is intractable pain that severely impacts quality of life.
Historical Context
Coccygectomy was first performed in the 18th century but remained controversial due to high complication rates. Modern surgical techniques, improved anesthesia, and better patient selection have significantly improved outcomes since the 1990s.
Who Is a Candidate for Coccygectomy?
Coccygectomy Surgery Explained: What to Expect
A clear walkthrough of the coccygectomy procedure, recovery stages, and what to expect post-surgery.
The distal portion of the coccyx is removed in most cases, preserving the sacrococcygeal joint where possible.
Proper patient selection is the most critical factor for success. Ideal candidates meet ALL of the following criteria:
Essential Criteria
Duration: Chronic coccyx pain lasting more than 6 months
Failed conservative treatment: Comprehensive trial including physical therapy, injections, medications, and lifestyle modifications
Clear diagnosis: Confirmed coccydynia with identifiable structural cause OR well-documented idiopathic coccydynia
Severe impact: Pain significantly impairs daily activities, work, or quality of life
Realistic expectations: Understanding that surgery is not guaranteed to resolve pain
Favorable Prognostic Factors
Patients with these characteristics have better surgical outcomes:
Traumatic origin: Pain began after specific injury (fall, childbirth)
Localized pain: Pain clearly isolated to coccyx, not diffuse
Temporary relief from injections: Positive response to diagnostic blocks
Normal body weight: BMI under 30 (obesity increases complication risk)
No psychological comorbidities: Depression and anxiety predict poorer outcomes
Younger age: Generally better healing under 60
Contraindications
Surgery should NOT be performed when:
Pain has atypical features suggesting referred pain from other sources
Patient has unrealistic expectations or significant psychological issues
Active infection present
Severe obesity (relative contraindication)
Patient unable or unwilling to comply with postoperative restrictions
Insufficient trial of conservative treatments
Preoperative Evaluation
Correct positioning post-surgery reduces pressure on the surgical site and speeds healing.
Comprehensive Assessment
Before surgery, your surgeon will conduct:
1. Detailed History
Pain onset and progression
Previous treatments and responses
Impact on daily functioning
Psychological screening
Expectations and goals
2. Physical Examination
External palpation of coccyx
Assessment of surrounding structures
Evaluation of sitting tolerance
Dynamic testing (pain with movement)
3. Imaging Studies
X-rays: Identify fractures, dislocations, spurs, or arthritis
Dynamic X-rays: Sitting and standing views to assess coccyx mobility
MRI: Evaluate soft tissues, bone marrow edema, rule out tumors
CT scan: Detailed bony anatomy if complex deformity suspected
4. Diagnostic Injections
Injection of local anesthetic around the coccyx or ganglion impar serves two purposes:
Diagnostic: Temporary relief confirms coccyx as pain source
Predictive: Good response to injection predicts surgical success
5. Psychological Evaluation
Many surgeons require psychological screening to identify:
Unrealistic expectations
Depression or anxiety that may affect outcomes
Secondary gain issues
Ability to cope with potential surgical failure
The Surgical Procedure
Surgery is reserved for cases where 6+ months of conservative care has failed to provide adequate relief.
Preoperative Preparation
Bowel preparation (enema) to clear rectum
Antibiotics to prevent infection
General anesthesia (patient completely asleep)
Positioning: Prone (face down) or lateral (side) position
Surgical Technique
Step 1: Incision
A small incision (3-5 cm) is made over the coccyx, typically vertically along the midline.
Step 2: Dissection
The surgeon carefully dissects through subcutaneous tissue, identifying and preserving important structures:
Posterior sacrococcygeal ligament
Anococcygeal ligament
Levator ani muscle attachments
Gluteus maximus attachments
Step 3: Coccyx Removal
The coccyx is detached from the sacrum at the sacrococcygeal joint. The surgeon may remove:
Partial coccygectomy: Only the mobile/distal segments
Total coccygectomy: Entire coccyx including sacrococcygeal joint
Most surgeons prefer total removal to prevent continued pain from remaining segments.
Step 4: Closure
The wound is closed in layers:
Deep layer: Absorbable sutures to muscle/fascia
Subcutaneous layer: Sutures to fat layer
Skin: Stitches or staples
A drain may be placed temporarily to prevent fluid accumulation.
Duration
The procedure typically takes 45-90 minutes depending on complexity.
Recovery Timeline
Days 1-3: Immediate Postoperative Period
Hospital stay for pain management and monitoring
IV pain medications
Wound care education
Assistance with first bowel movement
Discharge when pain controlled and tolerating diet
Week 1-2: Early Recovery

Final assessment of surgical outcome
Most patients know if surgery was successful
Return to all activities including sports
Surgical Risks and Complications
⚠️ Important: High Complication Rate
Coccygectomy has a complication rate of 15-30%, significantly higher than most orthopedic surgeries. This is due to the location (near anus, difficult to keep clean) and poor blood supply to the area.
Common Complications
1. Wound Infection (5-15%)
The most common complication. Proximity to the anus makes infection risk high.
Usually superficial, treated with antibiotics
Deep infection may require wound opening and drainage
Smokers and diabetics at higher risk
2. Wound Dehiscence (5-10%)
Wound opening due to tension or infection.
May require reclosure or healing by secondary intention
Prolongs recovery significantly
More common in obese patients
3. Persistent Pain (10-20%)
Surgery does not guarantee pain relief.
May indicate incorrect diagnosis
Could represent phantom pain or neuroma formation
May require further treatment or revision
4. Scar Pain (5-10%)
Painful scar tissue or neuroma (nerve bundle) formation.

Frequently Asked Questions
Will I miss my tailbone?
No. The coccyx has minimal functional importance. Most patients don't notice its absence after recovery.
Can I sit normally after surgery?
Most patients can sit normally within 2-3 months using a specialized cushion. Full normal sitting may take 4-6 months.
What if surgery doesn't work?
20-50% of patients have incomplete relief. Options include further injections, pain management, spinal cord stimulation, or psychological support for coping with chronic pain.
Is the scar visible?
The scar is in the gluteal cleft (buttock crease) and typically not visible when standing or sitting normally.
Can the coccyx grow back?
No. Once removed, the coccyx does not regenerate. However, painful scar tissue or bone spurs can form at the surgical site.
Bottom line: Coccygectomy can be life-changing for carefully selected patients with severe, intractable coccyx pain. However, the significant complication rate and variable success mean it should only be considered after exhaustive conservative treatment and thorough evaluation by an experienced surgeon.
