Coccygectomy.

What is a coccygectomy?

Coccygectomy involves removing part or all of the coccyx. It may be recommended for chronic coccygeal pain that remains debilitating despite appropriate treatments. The goal is to reduce pain and improve sitting tolerance.

This page describes surgery for mechanical coccydynia. A suspected tumour requires a assessment and specialized care pathway.

In what situations should it be discussed?

The decision is based on a combination of factors: well-localized pain, significant daily impact, correlation of the examination with previous investigations, and failure of previous treatments. One instability or a posterior dislocation may contribute to the indication.

An isolated radiological abnormality, in particular a fusion of segments, is not sufficient to justify the operation. A recent fracture is not a usual indication for coccygectomy.

An assessment before deciding.

The assessment reviews the history of pain, treatments tried, and their effectiveness. Dynamic standing-sitting radiographs assess mobility; an MRI may complement the examination depending on the context. It is also necessary to investigate other possible causes of pain.

Bring the images themselves, the reports, and information concerning previous injections: location, date, duration, and degree of relief.

Non-surgical options

Depending on the situation, management combines seating adjustments, offloading cushions, pain medication, and targeted rehabilitation. Injections or certain pain management procedures may be discussed. Their usefulness depends on the suspected mechanism and the response to previous treatment.

The consultation allows us to compare continuing these treatments with a possible intervention, depending on your goals.

Preparing for the procedure.

An anesthesia consultation and pre-operative instructions precede the operation. Inform the staff of your medications, allergies, medical history, and any infections or skin lesions near the surgical area. Do not modify anticoagulant or antiplatelet medication on your own.

The hospitalization procedures at Clinique du Parc Lyon, post-discharge care, and follow-up will be discussed with the team. Arrange your transportation and any necessary home care.

How is the procedure performed?

The procedure is usually performed under general anaesthesia. An incision provides access to the coccyx; the segments selected for removal in the surgical plan are removed while protecting the surrounding tissues, particularly the rectum lying in front. Wound closure and dressing help protect the incision.

The choice between partial and total resection depends on the assessment and findings during the operation. The planned technique is explained to you before the procedure.

Initial recovery and the scar

Surgical pain and discomfort when sitting are expected initially. Walking resumes according to the team's instructions. Alternating positions and avoiding prolonged pressure helps protect the surgical area.

Local care follows the prescription given upon discharge. A soiled or detached dressing, or an open wound, must be reported. Do not apply any non-prescribed product to the scar. Follow-up appointments will check the healing and adjust the care accordingly.

Resuming Your Daily Life

Returning to work depends in particular on the amount of time spent sitting, physical exertion, and the possibilities for workplace adjustments. Driving requires being able to get settled, move around, and brake without discomfort that compromises safety, and not taking any incompatible medication.

Return to sport is gradual, after approval from the team; activities that put direct pressure on the scar require special attention. Recovery is assessed over time, sometimes several months.

Outcomes on Pain and Complications

In Dr. Alexandre Journé's personal series of 420 operated coccyxes, with a reported follow-up of 12 years, 92% of patients experienced good to very good pain outcomes, with a postoperative infection rate of 8%. These results are based on clinical practice and do not constitute an individual guarantee. A good result does not necessarily mean complete pain relief.

Possible complications include:

• Surgical site infection: It may require care, antibiotics, and sometimes further surgery.
• Postoperative fluid-filled cysts: Fluid collections may appear in the operated area. Their nature and management depend on the examination and, if necessary, imaging.
• Residual pain: Some pain may persist despite the procedure and require further management.
• Phantom pain: Painful sensations may be felt in the area of the removed coccyx. Persistent pain should be reassessed before this explanation is considered.
• Late heterotopic ossifications: bone can form secondarily in the tissues of the operated area and sometimes cause discomfort or a recurrence of pain.

Healing problems, hematoma, or, more rarely, damage to surrounding structures are also possible. The risks related to anesthesia and your health are discussed before the operation.

Improvement may be gradual. However, any new or increasing pain should be reported without waiting for the next check-up.
