为何建议进行此手术

此手术称为近端指间关节融合术,旨在将您中指关节的骨骼连接在一起,使其融合为一块坚实的骨块。您的外科医生可能建议您进行此手术,原因是您患有严重的磨损性关节炎、复杂的损伤,或关节置换术后未能通过非手术治疗得到改善。尽管通常会先尝试夹板固定或康复治疗等其他治疗方法,但当这些方法不再能缓解您的疼痛或恢复关节稳定性时,则建议进行手术治疗。

主要目标是消除引起您不适的疼痛性活动,并为日常活动提供一个稳定的手指。尽管部分患者在术后长达 3 个月内可能仍会感到轻微疼痛,但该手术旨在为您提供持久的缓解和具有功能性的手部。当其他关节置换术失败,或关节过于不稳定以支持正常使用时,通常会选择此方法。

手术前

您需要在手术前禁食,并遵医嘱停用某些药物。请安排人乘车回家,并携带您目前所有药物的清单。当天请穿着舒适的衣物。您可能需要接受X光检查、血液检测或麻醉评估,以评估您的健康状况并规划手术。您的外科医生将在关节上方做一个单一的开放切口进行融合术。这种方法可以在保持手术简便的同时,直接到达目标区域。

手术当天

您到达医院后,将见到麻醉医生,讨论您的治疗方案。该手术在全身麻醉下进行。您在手术期间将完全处于睡眠状态。部分患者可能还会接受区域神经阻滞以缓解术后疼痛;麻醉医生将根据您的具体情况在当天决定。

您的外科医生将在手指上做一常规切口以进行手术。随后,您将被送入手术室,由医疗团队安全地实施操作。手术后,您将在复苏室苏醒,护士将密切监测您的状况,直至您出院回家。

手术内容

您的外科医生将在需要矫正的手指关节上方做一个切口。在关节内部,他们将准备关节面以便进行融合。如果您有特定的畸形(如天鹅颈畸形),您的外科医生可能会使用您手指上的肌腱制作一个悬吊装置。这有助于将关节固定在20至30度的屈曲位置。

为了使骨骼在愈合过程中保持稳定,您的外科医生将使用小型金属板和螺钉。这些固定装置通过切口放置,以牢固地固定关节。这种方法允许您在术后早期活动手指。在某些情况下,您的外科医生还可能同时固定下方的关节,以改善手指的运动功能。

手术完成后,您的外科医生将用缝线缝合切口。然后施加敷料以保护该区域。目标是创建一个稳定、无痛且位置正确的关节。

术后

您将在恢复室苏醒,疼痛将通过标准药物进行管理。您的手将被敷料包裹,您的外科医生可能会放置夹板以保持手指处于舒适位置。鼓励您轻柔地活动其他手指以减轻肿胀。大多数患者在此手术后需住院一晚,但部分患者可当天回家。您必须有人在最初的24小时内陪伴您,以提供帮助。您的外科医生通过在手指上方做一个切口进行开放手术。

恢复

在最初几天,您的手指可能会出现疼痛和肿胀。这是身体愈合过程中的正常现象。您的外科医生可能会将关节保持在轻微弯曲的位置以促进愈合。您可能会使用吊带或支带保护手指,使其在休息时得到固定。

起初,日常生活会有所不同。您会进行轻柔的练习以保持手指活动,但仅按照外科医生和物理治疗师的指导进行。在肿胀消退之前,一些简单的任务,如扣衬衫纽扣或拿杯子,可能会比较困难。起初睡眠可能会感到不适;建议将手垫高放在枕头上休息,以减轻肿胀。

随着时间推移,僵硬感会逐渐缓解,活动度也会恢复。您将逐渐在日常活动中更多地使用您的手。您的外科医生会根据您手指的愈合情况,告知您何时可以安全驾驶或重返工作岗位。每个人的愈合速度不同,因此您的恢复时间表可能会有所差异。您的外科医生和物理治疗师将指导您完成这一过程中的每一步。

可能发生的问题

大多数患者恢复良好,但偶尔也会出现并发症。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。

有时关节无法牢固愈合。这称为骨不连。您可能会注意到持续性疼痛,或感觉手指在应该僵硬时仍在活动。如果出现这种情况,您可能需要再次手术进行修复。

由于肌腱问题,您的手指可能无法正确活动。这称为伸肌机制功能障碍。您可能会感到突然无力,或发现无法完全伸直手指。这是关节置换术后需要再次手术的常见原因。

如果您之前接受过关节置换术,外科医生可能需要将关节融合作为备选方案。这称为关节融合术。虽然这有帮助,但效果并不总是完美,仍可能导致问题。您可能会获得尚可至良好的结果,但仍可能发生并发症。

年轻患者在接受关节置换术后,有时面临更高的再次手术几率。如果原始问题是由损伤引起的,这种情况尤为常见。

如果发生严重感染,外科医生可能需要执行分期手术。这意味着分两个独立步骤进行手术。与单次手术相比,这种两步法发生严重并发症的几率较低,尽管风险仍然存在。

本页面底部的并发症表格列出了典型的发生率,如需具体数据请参阅。

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。如出现突发剧烈疼痛、新发麻木或手指无法活动,也请及时联系。若出现小腿肿胀或呼吸困难,请立即前往急诊。这些症状需要紧急评估,以确保您的康复进程不受影响。
