为何建议进行此手术

此手术称为翻修反式肩关节置换术,是针对已磨损或失效的肩关节置换术进行的第二次手术。您的外科医生很可能建议进行此手术,因为您的初次植入物(设计使用寿命为 10 至 15 年)已松动或失效。大多数需要此手术的患者在初次手术后的平均时间为 3.9 年。通常先尝试非手术治疗,但当这些选项无法提供足够缓解时,则推荐手术。

此手术的主要目标是减轻疼痛并改善肩部功能。虽然该手术比初次手术具有更高的并发症风险,但可为许多人带来显著的长期改善。约 85% 的此类植入物在十年后仍保持在位且功能良好。这有助于您在之前的关节置换术无法再发挥作用时,恢复稳定性和日常功能。

手术前

您的外科医生将审查您当前的用药情况,并安排血液检查、X光片或麻醉评估,以确保您已做好术前准备。请携带完整的用药清单。手术前您需要禁食,并遵医嘱停用某些药物。请安排专人驾车送您回家。穿着舒适的衣物。您的外科医生将通过肩部上方的一个开放切口进行手术。大多数患者通过此方法可获得良好的短期效果,但若植入物松动,部分患者可能需要进一步手术。

手术当天

您到达医院后,将见到您的主刀医生和麻醉医生。本手术采用全身麻醉联合区域神经阻滞。手术期间您将完全处于睡眠状态,而神经阻滞(在苏醒前注射以麻醉支配手臂的神经)可为术后最初12至24小时提供镇痛效果。麻醉医生将在术前与您会面,并向您详细说明这两个部分。

随后,您将进入手术室,您的主刀医生将通过肩部上方的单个开放切口进行翻修手术。术后,您将在复苏室苏醒。在神经阻滞的镇痛效果开始发挥作用期间,您将受到密切监测。您的医疗团队将协助您安顿好,然后再将您转移至病房。

手术过程

您的外科医生将在肩部前方做一个切口以进入关节。这种开放入路允许他们移除您肩关节置换术中老化、磨损的部件。随后,他们将准备骨骼以适配新的金属和塑料组件。如果您的肩部存在感染,外科医生可能会清理该区域,并在放置新部件之前使用抗生素间隔器。

在某些情况下,您的外科医生会在关节盂处添加骨移植以重建骨结构。只要可能,他们会尝试将新的关节盂组件复位。对于骨骼脆弱的患者,您的外科医生可能会使用骨水泥或假体柄将新部件牢固地固定在位。随后,切口将通过缝合或钉合进行闭合,并敷上敷料。

由于该手术需要在现有硬件周围进行操作,因此比初次置换更为复杂。您的外科医生将根据初次置换失败的原因选择最佳的新假体。虽然手术耗时,但目标是恢复稳定性并缓解疼痛。在接下来的这一年里,您需要遵循特定的康复步骤,以帮助肩部愈合并改善活动功能。

术后

您将在复苏室苏醒。您的外科医生将采用标准方法管理您的疼痛。您将佩戴悬带,并且您的单一切口处会有敷料覆盖。大多数患者在此手术后需住院一晚,尽管部分患者可以在当天回家。您必须在最初的24小时内有人陪伴。早期活动是安全的,并有助于您的恢复。您可能在仅仅2周后就会感到疼痛非常轻微。您的外科医生旨在在一年内实现最大程度的改善。

恢复

在术后的头几天,您的肩部周围可能会出现酸痛和肿胀。大多数患者在两周后疼痛评分会显著降低。您的外科医生可能会建议您尽早进行主动活动,以帮助您安全、有效地恢复。这种方法比等待开始活动能带来更好的效果。

在肩部愈合期间,您需要佩戴吊带或支具以保护肩部。您的物理治疗师将指导您进行特定的锻炼,以恢复力量和活动范围。一旦您的外科医生允许,您就可以开始进行轻柔的日常活动。随着初期肿胀消退并找到舒适的睡姿,睡眠可能会变得更加轻松。

随着您逐渐恢复活动能力和握力,您的肩部功能将持续改善。大多数患者在术后一年达到最大医学改善。功能恢复在此时达到峰值,并在多年内保持稳定。您的个人恢复时间可能有所不同,因此您的外科医生和物理治疗师将为您制定具体的康复路径。

可能出现的并发症

大多数患者恢复良好,但偶尔也会出现一些问题。您的外科医生和医疗团队会密切监测您,以便尽早发现任何问题。

如果您感到深部、搏动性疼痛,且普通止痛药无法缓解,或注意到伤口周围出现扩散性红肿,您可能发生了感染。这被称为假体周围关节感染。如果您观察到这些迹象,应立即致电您的诊所。

有时,新关节部件周围的骨骼会发生松动。您可能会感到肩部活动方式突然改变,或听到新的咔哒声或摩擦感。如果出现这种情况,请联系您的外科医生以讨论后续步骤。

如果您的伤口看起来发红、肿胀或渗出液体,请立即告知您的医疗团队。这可能是伤口并发症。早期报告这一点非常重要,以便及时治疗。

如果您感到小腿突然肿胀和压痛,或出现呼吸困难,您可能发生了血栓。这被称为静脉血栓栓塞症。如果出现这些症状,请立即前往急诊科。

您可能还会感到肩部不稳定,或感觉关节有脱位感。这可能是由于骨骼或植入物松动所致。如果您有这种感觉,请联系您的外科医生。

本页面底部的并发症表格列出了典型的发生率,供您参考具体数据。

何时联系我们

如果您出现发热、伤口红肿加重或渗出,请立即联系我们。若出现突发剧烈疼痛、新发麻木或手臂无法活动,也请及时联系。如出现小腿肿胀或呼吸困难,请立即前往急诊。这些症状可能提示感染、血栓或其他紧急情况。您的主刀医生需立即评估,以确保肩部安全。

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.
