指间关节融合术后的X线片:靠近指甲的小关节已被固定为一个整体。骨骼在数周内融合,从而消除了关节疼痛,但代价是丧失了弯曲功能。 Kieran Hirpara 4.0

为何建议进行此手术

本页展示了罗克汉普顿 Mater 私人医院上肢外科医生 Kieran Hirpara 博士在门诊中对此类手术的处理方式。我们通过全科医生或物理治疗师的转诊接诊患者。门诊评估旨在明确您的诊断。对于长期的退行性关节炎,我们通常首先尝试非手术治疗。这包括调整活动方式、手部治疗、夹板固定和注射治疗。当上述措施未能带来足够改善时,我们会考虑手术。

指间关节(DIP)融合术是将手指末节骨与中节骨连接在一起。这将为您的手指末端提供一个稳定且无痛的状态。如果您的剧烈疼痛或不稳定限制了日常活动,您的外科医生可能会推荐此手术。该手术的目标是限制关节活动,从而消除疼痛。这使您能够在无不适的情况下抓握和持物。虽然融合术会限制关节活动,但它提供了可靠手部功能所需的稳定性。我们将此作为共同决策进行讨论,以帮助您以更少的疼痛回归日常生活。

手术前

请安排专人术后驾车送您回家。麻醉前需禁食禁水六小时。您的主刀医生将提供关于暂停哪些药物的具体指示。请将您目前服用的所有药物完整清单带入医院。您可能需要进行血液检查或麻醉评估,以确保您适合接受手术。我们还将拍摄X光片以确认关节的具体情况。请穿着宽松、舒适的衣物,以便更轻松地准备手术。请准时到达,以便我们为您进行单一切口的开放手术做好准备。

手术当天

您将在手术开始前不久抵达医院或手术中心。您的主刀医生将与您会面,确认手术细节并回答任何最后的疑问。随后,您将见到麻醉医生,他们将讨论针对您个人情况定制的疼痛控制和安全措施。本手术可在局部麻醉(仅麻醉手术区域,您保持清醒)或全身麻醉(完全入睡)下进行。大多数人选择局部麻醉——恢复更快,且术后不久即可回家。如果您更倾向于全身麻醉,这也是一个合理的选择——请与您的主刀医生和麻醉医生讨论。

一旦准备就绪,您将被送入手术室。您的主刀医生采用开放入路,在手术部位做一个常规的单一切口进行手术。这为关节融合提供了清晰的视野。手术本身较为简单,但此处不赘述具体步骤,相关内容将在下一节介绍。术后,您将在复苏室苏醒,护士将监测您的舒适度和循环状况。一旦您生命体征稳定且疼痛得到控制,当天即可出院回家。

手术内容

您的外科医生将在您的手指关节背侧做一个切口。这种开放入路为需要治疗的区域提供了清晰的视野。通过这个切口,您的外科医生会准备关节面,以确保它们能够牢固地愈合。

为了在骨骼融合期间保持骨骼位置,您的外科医生会使用固定在骨骼上的低剖面钢板。该钢板紧贴表面,有助于减少刺激。在某些情况下,会使用无头加压螺钉代替。这种螺钉位于骨骼内部,可提供强大的稳定性,而不会突出到周围组织中。您的外科医生会根据最适合您特定解剖结构的情况选择固定方法。

如果您在同一指节段的上下两个关节都进行手术,您的外科医生可能会使用细金属针。选择这些针是因为它们易于配合且不会相互干扰。这种协调确保了在一次手术中安全地治疗两个关节。

一旦骨骼固定完毕,您的外科医生会用缝线或钉合器关闭切口。然后施加无菌敷料以保护手术部位,从而开始您的康复过程。

术后

您将在复苏室苏醒,手部抬高并用敷料或夹板保护。大多数患者术后需住院一晚,但部分患者可在当天回家。我们会提供止痛药以确保您的舒适。您必须在术后24小时内由他人陪同照顾。保持敷料清洁干燥。佩戴手指夹板期间请勿驾驶,因为这会影响对方向盘的安全握持。待夹板拆除且您的外科医生许可后,方可恢复驾驶。有关更多详情,请参阅上肢手术后的驾驶

恢复

在最初几周内,您会注意到手指出现肿胀和僵硬。这是正常现象。您的外科医生将指导您通过休息和抬高患肢来管理这种不适。随着肿胀消退,您将开始进行轻柔的活动以保持关节灵活。我们使用夹板来保护正在愈合的手指。您必须按照指示佩戴夹板。

术后手部康复由 Extend Rehabilitation 的 Ruby Doolan 负责。我们的团队将教您简单的练习以恢复活动度和力量。一旦您的外科医生允许,您即可开始这些练习。早期活动有助于预防僵硬并支持更顺利的恢复过程。您将学习如何在不过度用力于愈合手指的情况下,用手完成日常任务。

在感觉舒适的情况下,您可以恢复轻度的家庭活动。在您的外科医生允许之前,请避免用力抓握或提举重物。驾驶需要牢固地握住方向盘。如果佩戴手指夹板限制了您的操控能力,则不能驾驶。一旦取下夹板并获得您的外科医生许可,您即可恢复驾驶。有关更多详细信息,请参阅我们的指南 上肢手术后的驾驶

您的恢复时间可能与他人不同。恢复情况取决于您的身体愈合能力和具体需求。您的外科医生和物理治疗师将指导您度过每个阶段。我们将一直支持您,直到您再次自信地使用您的手。

可能出现的问题

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的情况,以便尽早发现任何问题。

如果您的手指感觉异常僵硬或紧绷,这可能是关节未按预期活动的迹象。这种僵硬可能会限制您弯曲或伸直指尖的能力。请在随访就诊时告知您的外科医生,以便他们检查您的恢复进展。

您可能会注意到切口周围出现发红、发热或肿胀。这些症状可能表明皮肤或深层组织存在感染。如果您发现伤口有脓液流出或感到发烧,请立即联系诊所。早期治疗有助于防止感染扩散。

部分患者报告手指内有咔哒声、研磨感或弹响感。这种感觉通常意味着骨骼未能牢固融合。这称为骨不连。如果您在活动手指时听到或感觉到这种声音,请告知您的外科医生。他们可能需要拍摄新的 X 光片以观察骨骼愈合情况。

如果普通止痛药无法缓解疼痛,可能是出现问题的迹象。这可能是由于内固定物(螺钉或钢板)刺激皮肤或肌腱所致。如果感觉金属内固定物刺入皮下或在触碰时引起剧烈疼痛,请告知我们。我们可以评估在骨骼愈合后是否需要取出内固定物。

在极少数情况下,手指可能未能以正确的位置愈合。您可能会注意到指尖看起来弯曲或与其他手指排列不齐。这可能会影响手部的外观和功能。请与您的外科医生讨论任何关于手指外观或排列的担忧。

本页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,或突发剧烈疼痛,请立即联系我们。若发现小腿肿胀、呼吸困难、感觉丧失或无法活动肢体,请前往急诊。这些症状需要紧急评估。我们希望确保您的康复进程顺利,手部安全愈合。

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

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.
