您的感受

您可能在考虑大麻或CBD是否能帮助管理您的疼痛。处于您这种情况的许多患者都在询问同样的问题。一些脊柱疼痛患者估计,医用大麻可以治疗他们一半以上的症状。事实上,每三位脊柱疼痛患者中就有一位已经在使用医用大麻。

对于拇指腕掌关节骨关节炎患者,大量人群有兴趣尝试口服或外用医用大麻。大多数因手部和上肢问题就诊的患者会考虑使用医用大麻。他们认为这是治疗常见骨科疾病的一种安全治疗方案。然而,费用是许多人使用的主要障碍。

如果您接受过关节镜下肩袖修复术,CBD可以成为您疼痛管理计划的一部分。与安慰剂相比,在1年随访时,患者报告的结果未见缺陷。1年随访时也未见功能缺陷。您可以在术后疼痛管理中考虑使用CBD,而不会对结果产生不利影响或长期不利影响。

大麻类药物也适用于治疗周围神经病变。现有证据表明,医用大麻对慢性肌肉骨骼疼痛和神经病理性疼痛具有疗效和安全性。对于接受初次全膝关节置换术的患者,合成大麻素(THC)似乎不会限制阿片类药物的摄入量。

请注意,在全关节置换术的背景下,规律使用大麻可能与阿片类药物使用量增加有关。由于这种关联,目前无法基于此关联提出关于围手术期疼痛管理中大麻使用的具体指导。

骨科运动医学领域的多数调查受访者认为,CBD在术后和慢性疼痛管理中发挥作用。此外,79%的脊柱疼痛患者认为大麻可以减少阿片类药物的使用。虽然关于医用大麻在手部和上肢疾病中疗效的确定性结论仍需进一步研究,但许多人发现它有帮助。

实际发生的情况

您的身体使用复杂的受体系统来管理疼痛和炎症。大麻二酚(通常称为CBD)与该受体系统相互作用。在手术后(如关节镜下肩袖修复术)使用时,它不会导致患者报告结局的缺陷。这意味着您对结果的满意度与服用安慰剂时相同。

在一年的随访中,使用CBD未显示功能缺陷。您可以将其作为术后疼痛管理计划的一部分,而无需担心其对康复产生长期的不利影响。对许多人而言,它有助于管理不适,且不会妨碍您正常活动或使用肩膀。

基于大麻的药物也适用于治疗周围神经病变(即神经性疼痛)。现有证据表明,医用大麻对慢性肌肉骨骼疼痛和神经性疼痛具有疗效和安全性。然而,在全关节置换术(关节置换)的背景下,常规使用大麻可能与阿片类药物使用量增加有关。由于这种关联,目前无法就围手术期疼痛管理中大麻的具体使用提出指导建议。

患者经常寻求医用大麻以缓解疼痛。患有脊柱疼痛的患者估计,医用大麻可以治疗其超过一半的脊柱疼痛。三分之一的脊柱疼痛患者已经在使用医用大麻。79%的脊柱疼痛患者认为大麻可以减少阿片类药物的使用。

手部护理领域的兴趣同样高涨。大量患有拇指腕掌关节骨关节炎的患者有兴趣尝试口服或外用形式的医用大麻,以治疗其拇指腕掌关节疼痛。80.9%的因手部和上肢主诉就诊的患者表示会考虑使用医用大麻。患者认为医用大麻是常见骨科疾病的一种安全治疗选择。

合成形式的大麻素(THC)似乎不会限制原发性全膝关节置换术后的阿片类药物摄入量。骨科运动医学社区的大多数调查受访者认为,CBD在术后和慢性疼痛管理中发挥作用。然而,关于医用大麻在手部和上肢疾病中疗效的明确结论仍需进一步研究。成本被确定为因手部和上肢主诉就诊的患者使用医用大麻的主要障碍。

预期情况

您可能想知道大麻或CBD是否能帮助管理您的疼痛。目前的证据表明,CBD可以作为您疼痛管理计划的一部分,且不会对您的康复造成损害。例如,在关节镜下肩袖修复术后,与安慰剂相比,使用CBD并未导致一年后随访时患者报告的结局更差或功能缺陷更多。这意味着您可以将其作为多模式疼痛管理方案的一部分,而无需担心其对长期预后产生不利影响。

许多患者对这些治疗方式感兴趣。骨科运动医学领域的多数调查受访者认为,CBD在术后和慢性疼痛管理中发挥作用。大量患有拇指腕掌关节骨关节炎的患者有兴趣尝试口服或外用医用大麻。事实上,大多数因手部和上肢主诉就诊的患者会考虑使用医用大麻,其中80.9%的人认为这是一种安全的治疗选择。

然而,对于所有适应症,证据尚不明确。关于医用大麻在手部和上肢疾病中疗效的确切结论仍需进一步研究。您还应意识到,在全关节置换术的背景下,常规使用大麻可能与阿片类药物使用量增加有关。尽管如此,许多脊柱疼痛患者认为大麻可能减少阿片类药物使用;其中79%的人持有此观点。一些脊柱疼痛患者估计,医用大麻可以治疗他们超过一半的脊柱疼痛,且三分之一的人已经在使用它。

费用是使用医用大麻的主要障碍,尤其是在因手部和上肢主诉就诊的患者中。虽然目前的证据证明了其在慢性肌肉骨骼和神经病理性疼痛中的有效性和安全性,但您应与您的外科医生讨论这些选择。他们可以帮助您权衡潜在益处与成本以及个体风险,例如与关节置换手术中阿片类药物使用量增加相关的风险。
