We read with great interest the results of the randomised double‐blind controlled trial of platelet‐rich plasma (PRP) versus corticosteroid in caudal epidural injection for complex chronic degenerative spinal pain by Ruiz‐Lopez and Tsai.¹ This is a high‐quality study with a Jadad score of 4. A significant difference in pain scores was seen at the 6‐month observation point and there was a uniform improvement across multiple SF‐36 subdomains in the PRP group but not in the corticosteroid group.

给编辑的信回复：“一项随机双盲对照试验研究，比较尾端硬膜外注射中的白细胞富集血小板富集血浆和皮质类固醇治疗复杂慢性退行性脊髓痛”，作者：Ruiz-Lopez 和 Tsai

我们饶有兴趣地阅读了 Ruiz-Lopez 和 Tsai 进行的富血小板血浆 (PRP) 与皮质类固醇尾侧硬膜外注射治疗复杂慢性退行性脊柱疼痛的随机双盲对照试验的结果。¹这是一项高质量的研究，Jadad 评分为 4。在 6 个月的观察点，疼痛评分有显着差异，PRP 组的多个 SF-36 子域有统一的改善，但在皮质类固醇组。我们饶有兴趣地阅读了 Ruiz-Lopez 和 Tsai 进行的富血小板血浆 (PRP) 与皮质类固醇尾侧硬膜外注射治疗复杂慢性退行性脊柱疼痛的随机双盲对照试验的结果。¹ 这是一项高质量的研究，Jadad 评分为 4。在 6 个月的观察点，疼痛评分有显着差异，PRP 组的多个 SF-36 子域有统一的改善，但皮质类固醇没有团体。
