Aims. To determine if the results of treatment of adolescents with coccydynia are similar to those found in adults. Adult patients with coccydynia may benefit from injection therapy or operative treatment. There is little data evaluating treatment results in adolescents. We have treated adolescent patients similarly to adults and compared the outcomes. Methods. Overall, 32 adolescents with coccydynia were treated at our institution during a seven-year period; 28 responded to final follow-up questionnaires after a minimum of one year, 14 had been treated with only injection therapy, and 14 had been operated with coccygectomy. We collected data with regards to pain while sitting, leaning forward, rising from a sitting position, during defecation, while walking or jogging, and while travelling in trains, planes, or automobiles. Pain at follow-up was registered on a numeric pain scale. Each adolescent was then matched to adult patients, and results compared in a case control fashion. The treatment was considered successful if respondents were either completely well or much better at final follow-up after one to seven years. Results. Out of the 28 treated adolescents, 14 were regarded as successfully treated. Seven were somewhat better, and the remaining seven were unchanged. In the adult control group the corresponding number was 15 successfully treated, eight patients were somewhat better, and five were unchanged. Six of the 14 successfully treated adolescents had been operated. There were no significant differences between the groups in the various registered domains, or on numeric pain scale. Conclusion. Treatment results in adolescent patients seem similar to those in adults. The long-term success rate of injection therapy is low. In case of injection treatment failure, operation may be considered, also in adolescents

Aims. We aimed to establish the short- and long-term efficacy of corticosteroid injection for coccydynia, and to determine if betamethasone or triamcinolone has the best effect. Methods. During 2009 to 2016, we treated 277 patients with chronic coccydynia with either one 6 mg betamethasone or one 20 mg triamcinolone cortisone injection. A susequent injection was given to 62 (26%) of the patients. All were reviewed three to four months after injection, and 241 replied to a questionnaire a mean of 36 months (12 to 88) after the last injection. No pain at the early review was considered early success. When the patient had not been subsequently operated on, and indicated on the questionnaire that they were either well or much better, it was considered a long-term success. Results. At the three- to four-month review, 22 (9%) reported that they had no pain. The long-term success of one injection was 15% and rose to 29% after a second injection. Logistic regression tests showed that both early success (odds ratio (OR) 5.5, 95% confidence interval (CI) 2.1 to 14.4; p = 0.001) and late success (OR 3.7, 95% CI 1.7 to 8.3; p = 0.001) was greater with triamcinolone than with betamethasone. Late success was greater for patients with symptoms for less than 12 months (OR 3.0, 95% CI 1.4 to 6.7; p = 0.006). We saw no complications of the injections. Conclusion. We conclude that the effect of corticosteroid injection for coccygodynia is moderate, possibly because we used modest doses of the drugs. Even so, they seem worthwhile as they are easily and quickly performed, and complications are rare. If the choice is between injections of betamethasone or triamcinolone, the latter should be selected. Cite this article: Bone Joint Open 2020;1-11:709–714

Aims. The aim of this study was to identify factors associated with poor outcome following coccygectomy on patients with chronic coccydynia and instability of the coccyx. Methods. From the Danish National Spine Registry, DaneSpine, 134 consecutive patients were identified from a single centre who had coccygectomy from 2011 to 2019. Patient demographic data and patient-reported outcomes, including pain measured on a visual analogue scale (VAS), Oswestry Disability Index (ODI), EuroQol five-dimension five-level questionnaire, and 36-Item Short-Form Health Survey questionnaire (SF-36) were obtained at baseline and at one-year follow-up. Patient satisfaction was obtained at follow-up. Regression analysis, including age, sex, smoking status, BMI, duration of symptoms, work status, welfare payment, preoperative VAS, ODI, and SF-36 was performed to identify factors associated with dissatisfaction with results at one-year follow-up. Results. A minimum of one year follow-up was available in 112 patients (84%). Mean age was 41.9 years (15 to 78) and 97 of the patients were female (87%). Regression showed no statistically significant association between the investigated prognostic factors and a poor outcome following coccygectomy. The satisfied group showed a statistically significant improvement in patient-reported outcomes at one-year follow-up from baseline, whereas the dissatisfied group did not show a significant improvement. Conclusion. We did not identify factors associated with poor outcome following coccygectomy. This suggests that neither of the included parameters should be considered contraindications for coccygectomy in patients with chronic coccydynia and instability of the coccyx.

Coccygectomy, surgical excision of the coccyx, may be used to treat coccydynia, a chronic and disabling condition of the lowest part of the spine. It is a controversial and infrequently performed operation that many surgeons are reluctant to perform due to the risks of rectal perforation and infection. The criteria for patient selection for coccygectomy remain ill-defined. We present a single surgeon case series of 17 patients who underwent coccygectomy for chronic coccydynia. This was a retrospective observarional case series analysis. Case notes of 17 patients who underwent coccygectomy from 1999 -2009 were obtained and analysed. We then carried out telephone survey for which only 15 patients were contactable. We used the Milton Keynes Orthopaedic Patient Satisfaction survey and the modified Oswestry low back pain disability questionnaire. All patients had a two to three year history of coccydynia; 15 following trauma, one following a caudal injection and one following birth delivery. All patients had received between one and five lignocaine/methylprednisolone injections prior to coccygectomy, with documented initial symptom relief. All 17 patients had documented hypermobile sacro-coccygeal joints. Post-operative symptom relief varied between 60% and 100%, with all patients reporting that they would have their surgery again. Complications included three post-operative wound infections. There were no cases of rectal perforation. Coccygectomy for intractable coccydynia is sometimes the only option available. With good patient selection, including identification of a hypermobile joint with initial symptom relief following local injection, coccygectomy is a successful and safe treatment

Aim: Retrospective review of patients after coccygectomy for post traumatic coccydynia. Methods: 13 patients (2 male, 11 female; mean age 37.8 years) who had undergone coccygectomy in our unit between 1995–2005 were identified and their case notes were reviewed. All patients had coccydynia with clear history of trauma, had failed to respond to three MUA and injections, and on clinical examination by senior author had hypermobile coccyx. All patients were operated by the senior author, using a standard technique whereby all segments of the coccyx from sacrococcygeal joint were excised. At follow up postal questionnaire was sent to all patients. This included, Visual Analogue Score (VAS) for Pain now and VAS for pain over one week, overall patient satisfaction, and Oswestry disability Index (ODI), The non-respondents were contacted by telephone 3 weeks later. Overall response was 100%. RESULTS: Mean time from the onset of symptoms to coccygectomy was 23.8 months (range 5–72). Average length of follow up was 3.8 years (range 0.7–10.8). 6 patients (46%) had 0 pain for VAS now and VAS over one week. 2 patients (15%) had mild pain VAS (1,2) for pain now and over 1 week, and 4 patients(31%) had moderate pain VAS (5,5,5,6) for pain now and VAS (5,5,5,5) for pain over 1 week and 1 patient (8%) had severe pain VAS (8). ODI was normal or mild disability (0–20%) in 8 patients (71%), 4 patients had moderate disability (ODI 21–40%) and 1 had sever disability (ODI 54%). Overall Ten patients (76.9%) were satisfied with the result and would consider the same surgery again. Conclusion: Surgical treatment of post traumatic coccydynia resistant to conservative measures can lead to satisfactory results, if appropriate patient selection criteria are applied

Purpose of the study. To take a snapshot opinion of General Practitioner understanding of the prevalence, diagnosis and management of coccydynia. Methodology. We designed a simple 5 question survey to administer to our local GPs. The survey was sent to 107 GP practices in Devon whose details were provided by The Devon Access Referral Team. We received 128 electronic replies. We also submitted the survey to 50 GPs who attended a study day at our institution – and ensured they had not already completed the electronic format of the same work. Thus we received 178 replies which we believe to be a highly representative sample of our local GPs opinion. Results. 53% correctly identified the prevalence of the condition. 42% believed the condition to be associated with an underlying psychological disorder. 58% believed there was no proven treatment for the condition. Less than 18% would consider referring the patient to any secondary care service that dealt with chronic spinal pain (Pain clinic, rheumatology or spinal surgery) even if the symptoms persisted beyond 3 months duration. 73% believed surgery was madness or had a less than 20% chance of relieving symptoms. Conclusion. Coccydynia is a painful condition, causing significant distress for those suffering with the condition. Primary care physicians seem reluctant to recognise the problem as significant and reluctant to refer patients for treatment that may offer significant symptomatic relief. Education about the condition is required

Problem Chronic disabling pain in the sacrococcygeal region is regarded by clinicians with great dismay because of unpredictability of the treatment outcome. The subject is under- represented in the literature. Method Thirty eight patients with intractable coccydynia had imaging investigations for the spine other than X-rays. Six of these patients were also investigated by means of sacrococcygeal and intercoccygeal discography. The excised specimen with intact sacrococcygeral joint was sent for histological examination in 22 patients. Patients’ assessment of the benefit of coccygectomy was conducted by telephonic interview. Results After a mean post surgical follow up of 6.75 years (range 2–16 yrs), results were available for 31 out of 38 patients. 16 patients benefited greatly from the surgery and 6 benefited to some extent, giving an overall good result of 71%. 7 patients had no or little relief from surgery (29%). Moderate to severe degenerate changes in SC and IC joints on histology were found in 59% of patients. 91.6 % of these patients did well with surgery. Only 60 % of those with mild changes did well. Discography was possible in five out of six attempted cases. Two were positive and both did well from surgery. Three patients had negative discographies and two of them had a poor result and one had only some relief. Conclusions Degenerate changes in sacrococcygeal discs give rise to pain. Surgical results are better in those with a severe degree of degenerative change. It is possible to identify these with discography, though a larger study needs to be carried out

To determine the demographic, pre-operative, operative, post-operative, and outcome in seven patients who presented to our unit over a 5-year period and underwent a coccydectomy for coccydynia unresponsive to conservative measures. We performed a retrospective chart review of seven patients who presented to the Department of Orthopaedics at Helen Joseph hospital, University of the Witwatersrand, Johannesburg, South Africa, with coccidia unresponsive to a trial of adequate conservative measures, and underwent operative intervention. The study period was from 01 January 2014 to 31 December 2018. The mean age of subjects in our study was 53 years. The average length of conservative treatment prior to presentation to our unit was 8 months. All patients were taken to surgery and the mean length of surgery was 49 min and the mean volume of intra-operative blood loss was 63.4 ml. In all 7 (100%) of subjects a total coccygectomy was performed. At our 1-year end point all 7 (100%) subjects reported a favourable outcome and were satisfied – extremely satisfied with the procedure. In our study a total coccygectomy resulted in a significant reduction in coccygeal pain and subjects a 1-year follow-up end point. We recommend that in patients who fail an adequate recognized trial of conservative measures for coccydynia, a total coccygectomy should be performed
