First Coccygeal Vertebra Dislocation Treated by Open Reduction and Internal Fixation

STUDY DESIGN: Case report. OBJECTIVES: To report the effectiveness of open reduction and internal (screw) fixation treatment performed to treat dislocation of the first coccygeal vertebra. SUMMARY OF LITERATURE REVIEW: Most treatment methods for coccygeal dislocation were conservative treatment for acute coccygodynia and coccygectomy for chronic coccygodynia. MATERIALS AND METHODS: A 18-year-old female presented with severe coccygodynia due to a fall down the stairs. Computed tomography showed dislocation of the first coccygeal vertebra. We performed open reduction and internal fixation with a 4.0-mm shortthread cancellous screw with a washer, with no additional procedure for bone union. RESULTS: Union was achieved 10 weeks postoperatively. CONCLUSIONS: Open reduction and internal (screw) fixation can be a useful method for coccygeal vertebra dislocation.

Clinical Outcomes of Coccygectomy for Chronic Coccygodynia

STUDY DESIGN: Retrospective study. OBJECTIVES: To confirm the clinical outcomes of coccygectomy for intractable chronic coccygodynia. SUMMARY OF LITERATURE REVIEW: Coccygectomy has been reported to be one of the good options for the failure of conservative treatment. MATERIALS AND METHODS: A retrospective review was conducted, including nine patients who underwent coccygectomy for intractable chronic coccygodynia. RESULTS: Improvements in the mean visual analogue scale (VAS) scores, from 5.6 to 2.1, were observed. As for patient satisfaction, there were four cases with excellent outcomes, three with good outcomes, one with a fair outcome, and only one with a poor outcome. Surgical complications, such as wound infection, did not occur in any of the cases. CONCLUSIONS: Irrespective of the causes, coccygectomy for chronic coccygodynia, for which nonsurgical management, including cushions, nonsteroidal anti-inflammatory drugs, and corticosteroid injections, has no effect, is considered a useful method because it brings definite pain relief and leads to high patient satisfaction.

Coccygectomy for Treatment of Coccygodynia / 대한정형외과학회잡지

PURPOSE: Coccygodynia is a painful condition localized in the region of the coccyx. Most cases of coccygodynia are treated conservatively. However, we conducted an analysis of patients who underwent coccygectomy, with chronic intractable coccygodynia and assessed the results of their treatment. MATERIALS AND METHODS: From March 2003 to August 2013, this study was conducted in order to investigate the benefit of coccygectomy in cases where conservative treatment has failed. We compared preoperative and postoperative visual analog scales (VAS) scores and confirmed duration of symptom free, complications. RESULTS: The average duration of symptom free was 3.4 months, and VAS score improved from 7.3 to 1.6. There was one wound infection. CONCLUSION: We can obtain satisfactory results through coccygectomy for chronic intractable coccygodynia.

Coccygodynia and Coccygectomy

OBJECTIVE: A review of the literature on coccygectomy and our patients was performed to assess the effectiveness of coccygectomy for chronic refractory coccygodynia. METHODS: An English language PubMed search was conducted with the terms "coccygodynia" and "coccygectomy" from January 1980 to January 2012. We retrospectively reviewed the medical records and performed telephone questionnaire on 61 patients who underwent coccygectomy at UCDMC between 1997 and 2009. RESULTS: There were 28 case series from 1980 to 2012 for a total of 742 patients who underwent coccygectomy following failed conservative management. The mean age ranged from 26.4 to 52.8 years. The most common cause was direct trauma (58.5%) with a male:female ratio of 1:5.2. Most patients (84%) had a good to excellent outcome after coccygectomy. The most common complication is wound infection (10.0%). The overall complication rate was 13.3%. Similarly, 84.6% of patients from our own surgical case series reported good to excellent outcomes with 11.5% wound infection. CONCLUSION: Coccygectomy is an effective treatment for chronic refractory coccygodynia. The surgery isrelatively simple to perform but precaution must be taken to avoid wound infection.

Coccigodínias: diagnóstico por imagem / Coccygodynia: diagnostic imaging

Coccigodínia é uma síndrome dolorosa de difícil abordagem diagnóstica e terapêutica, ainda mal compreendida por clínicos, ortopedistas e radiologistas. No intuito de entender e diferenciar as anormalidades clínico-radiológicas encontradas nas coccigodínias, revisamos a anatomia normal do sacro-cóccix e das demais estruturas pélvicas, suas variações e alterações anatômicas, além doselementos biomecânicos e fisiopatológicos implicados na etiologia da dor. O estudo radiológico funcional do cóccix consiste na obtenção de incidências de perfil nas posições ortostática e sentada, que permite a determinação da mobilidade coccígea. Este método pode demonstrar lesãocausal em 70% dos casos de coccigodínia. A classificação radiológica segundo as alterações da dinâmica do cóccix pode orientar tratamentos e comparar respostas terapêuticas por subgrupos.

Coccygodynia is a painful syndrome still misunderstood by physicians. To understand the radiological abnormalities that may accompanythis syndrome we have revised sacro-coccygeal normal anatomy and its variants and biomechanical elements that may produce pain. Functional radiologic studies of the coccyx consistin lateral projection in upright and sitted positions. Such projections provide clues for the evaluation of coccygeal mobility and may disclose the causal lesion producing coccygodynia in about 70%of the patients. Radiologic classification of the dynamic dysfunctions of coccygeal mobility may orient treatments and compare outcomes in subgroups.

The Use of Radiofrequency Lesion Generation on the Ganglion Impar for the Treatment of Chronic Coccygodynia: A case report / 대한마취과학회지

Coccygodynia is a common problem that is characterized by pain in the tailbone that radiates to the lower sacral and perineal areas. Coccygodynia may occur after a fall in the sitting position or damage to the sacrococcygeal ligament during a difficult vaginal delivery.Currently, the therapeutic options for coccygodynia are unclear, however, a number of treatment approaches have been proposed.In this case a favorable outcome was obtained by using a radiofrequency lesion generator to create a lesion on the ganglion impar in a patient with chronic coccygodynia.

Clinical and radiological differences between traumatic and idiopathic coccygodynia

Several reports of coccygodynia have been confined to the causes, the methods of treatment, and the methods of radiological examination. As far as we know, there has been no previous study about the objective measurement of the coccyx. The purpose of this study was to find the possible cause of idiopathic coccygodynia by comparing the clinical and radiological differences between traumatic and idiopathic coccygodynia by innovative objective clinical and radiological measurements. Thirty-two patients with coccygodynia were evaluated retrospectively. We divided the patients into two groups. Group 1 consisted of 19 patients with traumatic coccygodynia and group 2 consisted of 13 patients with idiopathic coccygodynia. We reviewed medical records and checked age, sex distribution, symptoms, and treatment outcome in each group. We also reviewed coccyx AP and lateral views of plain radiological film and measured the number of coccyx segments and the intercoccygeal angle in each group. The intercoccygeal angle devised by the authors was defined as the angle between the first and last segment of the coccyx. We also checked the intercoccygeal angle in a normal control group, which consisted of 18 women and 2 men, to observe the reference value of the intercoccygeal angle. The outcome of treatment was assessed by a visual analogue scale based on the pain score. Statistical analysis was done with Mann-Whitney U test and Chi-square test. Group 1 consisted of 1 male and 18 female patients, while group 2 consisted of 2 male and 11 female patients. There were no statistically significant differences between the traumatic and idiopathic coccygodynia groups in terms of age (38.7 years versus 36.5 years), male/female sex ratio (1/18 versus 2/11), and the number of coccyx segments (2.9 versus 2.7). There were significant differences between the traumatic and idiopathic coccygodynia groups in terms of the pain score (pain on sitting: 82 versus 47, pain on defecation: 39 versus 87), the intercoccygeal angle (47.9 degree versus 72.2 degrees), and the satisfactory outcome of conservative treatment (47.4% versus 92.3%). The reference value of the intercoccygeal angle in the normal control group was 52.3 degrees, which was significantly different from that of the idiopathic group. In conclusion, the intercoccygeal angle of the idiopathic coccygodynia group was greater than that of the traumatic group and normal control group. Based on the results of this study, the increased intercoccygeal angle can be considered a possible cause of idiopathic coccygodynia. The intercoccygeal angle was a useful radiological measurement to evaluate the forward angulation deformity of the coccyx.
