Aims. The aim of this study was to investigate the efficacy of coccygectomy in patients with persistent coccydynia and coccygeal instability. Methods. The Danish National Spine Registry, DaneSpine, was used to identify 134 consecutive patients who underwent surgery, performed by a single surgeon between 2011 and 2019. Routine demographic data, surgical variables, and patient-reported outcomes, including a visual analogue scale (VAS) (0 to 100) for pain, Oswestry Disability Index (ODI), EuroQol five-dimension questionnaire (EQ-5D), and the Physical Component Score (PCS) and Mental Component Score (MCS) of the 36-Item Short-Form Health Survey questionnaire (SF-36) were collected at baseline and one-year postoperatively. Results. A total of 112 (84%) patients with a minimum follow-up of one year had data available for analysis. Their mean age was 41.9 years, and 15 (13%) were males. At 12 months postoperatively, there were statistically significant improvements (p < 0.001) from baseline for the mean VAS for pain (70.99 to 35.34), EQ-5D (0.52 to 0.75), ODI (31.84 to 18.00), and SF-36 PCS (38.17 to 44.74). A total of 78 patients (70%) were satisfied with the outcome of treatment. Conclusion. Patients with persistent coccydynia and coccygeal instability resistant to nonoperative treatment may benefit from coccygectomy. Cite this article: Bone Joint J 2021;103-B(3):542–546

Aims. The purpose of this prospective study was to evaluate the outcomes of coccygectomy for patients with chronic coccydynia. . Patients and Methods. Between 2007 and 2011, 98 patients underwent coccygectomy for chronic coccydynia. The patients were aged > 18 years, had coccygeal pain, local tenderness and a radiological abnormality, and had failed conservative management. Outcome measures were the Short Form 36 (SF-36), the Oswestry Disability Index (ODI) and a visual analogue scale (VAS) for pain. Secondary analysis compared the pre-operative features and the outcomes of patients with successful and failed treatment, two years post-operatively. The threshold for success was based on a minimum clinically important difference (MCID) on the ODI of 20 points. All other patients, including those lost to follow-up, were classified as failures. Results. There was significant improvement in all ten components of the SF-36 (p < 0.05), the ODI (23 points) and VAS (39 points) (p < 0.0001). A total of 69 patients (70.4%) met the designated MCID threshold for a successful outcome. The failure group consisted of 25 patients (25.5%) who did not reach the MCID and four (4.1%) who were lost to follow-up. Six patients (6.1%) in the failure group had ODI scores that were no better or worse than that pre-operatively. The patients in whom treatment failed had significantly worse pre-operative scores for the ODI (p = 0.04), VAS (p = 0.02) and on five of ten SF-36 components (p < 0.04). They also had a higher incidence of psychiatric disorders, pre-operative opiate use and more than three comorbidities. . Take home message: Coccygectomy for chronic coccydynia results in significant improvement in patient-reported outcomes at two years. Failure is associated with certain pre-operative characteristics such as psychiatric illness, poor quality of life features, higher levels of pain, and use of opiates.

Coccydynia is a painful disorder characterised by coccygeal pain which is typically exaggerated by pressure. It remains an unsolved mystery because of the perceived unpredictability of the origin of the pain, some psychological traits that may be associated with the disorder, the presence of diverse treatment options, and varied outcomes. A more detailed classification based on the aetiology and pathoanatomy of coccydynia helps to identify patients who may benefit from conservative and surgical management. This review focuses on the pathoanatomy, aetiology, clinical features, radiology, treatment and outcome of coccydynia

Between 1993 and 2008, 41 patients underwent total coccygectomy for coccydynia which had failed to respond to six months of conservative management. Of these, 40 patients were available for clinical review and 39 completed a questionnaire giving their evaluation of the effect of the operation. Excellent or good results were obtained in 33 of the 41 patients, comprising 18 of the 21 patients with coccydynia due to trauma, five of the eight patients with symptoms following childbirth and ten of 12 idiopathic onset. In eight patients the results were moderate or poor, although none described worse pain after the operation. The only post-operative complication was superficial wound infection which occurred in five patients and which settled fully with antibiotic treatment. One patient required re-operation for excision of the distal cornua of the sacrum. Total coccygectomy offered satisfactory relief of pain in the majority of patients regardless of the cause of their symptoms

Coccygectomy is a controversial operation. Some authors have reported good results, but others advise against the procedure. The criteria for selection are ill-defined. We describe a study to validate an objective criterion for patient selection, namely radiological instability of the coccyx as judged by intermittent subluxation or hypermobility seen on lateral dynamic radiographs when sitting.

We enrolled prospectively 37 patients with chronic pain because of coccygeal instability unrelieved by conservative treatment who were not involved in litigation. The operation was performed by the same surgeon. Patients were followed up for a minimum of two years after coccygectomy, with independent assessment at two years. There were 23 excellent, 11 good and three poor results. The mean time to definitive improvement was four to eight months. Coccygectomy gave good results in this group of patients.

A five-year prospective trial involving 120 patients was undertaken to investigate the aetiology and treatment of coccydynia. The cause lies in some localised musculoskeletal abnormality in the coccygeal region. Lumbosacral disc prolapse is not a significant factor. The condition is genuine and distressing and we found no evidence of neurosis in our patients. Physiotherapy was of little help in treatment but 60% of patients responded to local injections of corticosteroid and local anaesthesia. Manipulation and injection was even more successful and cured about 85%. Coccygectomy was required in almost 20% and had a success rate of over 90%

Fifteen patients with identical symptoms of pain and tenderness at the tip of the greater trochanter are reviewed. Diagnosis by the referring doctor was usually osteoarthritis of the hip or sciatica, but localised tenderness and pain on resisted abduction were the only clinical signs. Radiographs were usually normal. Most cases were relieved by one or more local steroid injections. This disorder has much in common with tennis elbow, golfer's elbow, coccydynia and policeman's heel. We suggest that all these conditions may be traction syndromes

Two cases of coccydynia are presented. Their definitive treatment was excision of the coccyx and the pericoccygeal tissues. The histology in both cases revealed a glomus tumour of the coccygeal body and the symptoms were completely relieved after operation. Glomus tumours of the coccygeal body may be the cause of some cases of coccydynia

1. Coccygeal pain in a young man, persisting for ten years in all and for seven years after partial removal of the coccyx, was shown to be due to an intrathecal tumour of the cauda equina.

2. Removal of the tumour, which was found to be an ependymoma, gave complete relief.

1. Twenty-eight patients subjected to excision of the coccyx for coccygeal pain during the last ten years have been reviewed.

2. No constant means of selection appears to have been used in recommending these patients for operation, and, in retrospect, no factor in the history or examination emerges as reliable for making such selection in the future.

3. Operation may be recommended as likely to provide a cure in about 45 per cent and to give worthwhile relief in another 45 per cent of cases.

4. When conservative treatment has succeeded, operation will not, of course, be required, but failure of conservative treatment is not an essential pre-requisite in recommending operation.

5. If more care were taken to eliminate the markedly psychoneurotic patients the worthwhile results of operation could probably be increased even above 90 per cent.

6. Excision of the coccyx is certainly a useful operation and should not be discarded.
