扳机指/拇指是指拇指或手指卡在弯曲位置,随后以“弹响”方式伸直的状况。这是由于炎症导致空间变窄,屈肌腱无法通过所致。肌腱是连接肌肉和骨骼的坚韧组织带。手部和手臂中的肌腱与肌肉共同作用,使手指和拇指弯曲和伸直。扳机指/拇指会使手指或拇指的活动和抓握变得困难。

扳机指/扳机拇指的病因是什么?

扳机指示意图:屈肌腱在通过狭窄的腱鞘时发生卡压
  • 工作或爱好涉及反复抓握动作的人,患扳机指的风险更高。
  • 类风湿性关节炎
  • 糖尿病
  • 女性患病率比男性高三分之二
  • 通常影响 40-60 岁之间的人群

症状

  • 手指或拇指根部酸痛。
  • 弯曲或伸直手指时出现疼痛性弹响或卡顿。这种卡顿感在拇指或手指休息后往往加重,活动后则有所缓解。
  • 在某些情况下,随着病情进展,手指或拇指会锁定在弯曲或伸直的位置,需用另一只手轻轻将其扳直。

手部治疗如何提供帮助?

  • 治疗的目标是减轻炎症,使屈肌腱能够平滑滑动,从而让手指活动而不发生“扳机”现象。
  • 这可以通过以下方式实现:
    • 使用支具——支具的目标是减少受刺激肌腱的活动。
    • 皮质类固醇注射——这有助于缓解屈肌腱的炎症和疼痛。皮质类固醇注射也可与支具联合使用。
    • 手术——通过手术松解腱鞘,使屈肌腱能够平滑滑动。

您可以采取的措施

  1. 通过以下方式减轻肿胀:
    • 加压包扎
    • 保持手部抬高
    • 冰敷(前48小时)
    • 轻柔的泵动练习
  2. 在拆线并与治疗师讨论之前,请勿让手部沾水。
  3. 手部用于轻度活动:
    • 只要疼痛允许,您即可开始使用手部进行轻度任务,例如穿衣、进食等。随着时间推移,在可耐受的范围内,逐渐增加手部使用频率并尝试其他任务。
    • 只要疼痛允许且您能安全控制车辆,即可驾驶。
    • 术后避免过度使用手部非常重要,因为这可能会延缓愈合。如果在日常活动使用手部后,您注意到疼痛或肿胀显著增加,应减少活动直至手部恢复。

练习

肘部支撑,手指放松,手腕向前和向后弯曲。

1. 腱固定作用

肘部支撑,手指放松,将手腕向前弯曲,然后向后弯曲。

手指尽可能伸直,另一只手进一步推压。

2. 主动复合伸指

将肘部支撑在桌面上,尽可能伸直手指,并用另一只手进一步推压。数到5,然后放松。

手掌平放于桌面,掌心向下,另一只手按压手背施加压力。

3. 被动复合伸展

将手掌平放在桌面上(掌心向下)。在手背施加压力,并向身体方向“按摩”。数到5,然后放松。

另一只手握住指端关节褶皱下方,同时指端关节弯曲。

4. 阻挡下远端指间关节屈曲

用另一只手握住并支撑指端关节褶皱下方的手指。仅弯曲指端关节。数到5,然后放松。

三种手部姿势:松握拳、钩状位,随后手指伸直并外展。

5. 松拳

支撑手腕背部,握一个松拳——然后“钩”——然后伸直并张开手指。

拇指指尖触及食指指尖。

6. 拇指对掌

手指伸直并放松。将拇指指尖与食指指尖相触。保持5秒。回到伸直位置。依次用中指、无名指和小指重复此动作。

每天 3-4 次,每次 10 次

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and conditions that creators and other rights holders may use to share original works of authorship and other material subject to copyright and certain other rights specified in the public license below.

Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC- licensed material, or material used under an exception or limitation to copyright.

If the licensor's permission is not necessary for any reason--for example, because of any applicable exception or limitation to copyright--then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable.

Section 2 -- Scope.

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

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.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

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.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
