The aim of this study was to investigate the efficacy of coccygectomy in patients with persistent coccydynia and coccygeal instability.
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.
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.
Patients with persistent coccydynia and coccygeal instability resistant to nonoperative treatment may benefit from coccygectomy. Cite this article: 2021;103-B(3):542-546.
本研究旨在探讨尾骨切除术治疗持续性尾痛和尾骨不稳定的疗效。
使用丹麦国家脊柱注册中心（DaneSpine），确定 2011 年至 2019 年间由同一位外科医生进行手术的 134 例连续患者。收集常规人口统计学数据、手术变量和患者报告的结果，包括疼痛的视觉模拟量表（VAS）（0-100）、Oswestry 残疾指数（ODI）、欧洲五维健康量表（EQ-5D）以及 36 项简明健康调查问卷（SF-36）的身体成分评分（PCS）和心理成分评分（MCS）。在基线和术后一年时进行评估。
共有 112 例（84%）患者至少随访一年，其数据可用于分析。他们的平均年龄为 41.9 岁，15 例（13%）为男性。术后 12 个月，疼痛 VAS（从 70.99 降至 35.34）、EQ-5D（从 0.52 升至 0.75）、ODI（从 31.84 降至 18.00）和 SF-36 PCS（从 38.17 升至 44.74）的平均值均有统计学显著改善（p < 0.001）。78 例患者（70%）对治疗结果满意。
对非手术治疗无效的持续性尾痛和尾骨不稳定患者，尾骨切除术可能有益。
