您的感受

您可能会注意到肘部出现疼痛或刺痛,尤其是在手臂长时间弯曲时。这种情况常发生在夜间,当您睡觉时将肘部枕在枕头下时。您可能会在醒来时发现手部麻木,或者感觉手臂“睡着了”的次数比平时更多。

当神经受到刺激时,日常活动可能会变得困难。将手伸到背后扣文胸或把衬衫塞进裤子里可能会引起剧烈疼痛或无力。提重物或将手臂向侧面伸出可能会使症状加重。您可能会发现难以牢固地抓握物品,或者感觉手部笨拙。

您的外科医生可能会建议进行二次减压联合神经包裹术以帮助缓解。这种方法对于有复发性症状的患者来说是安全且有效的。虽然包裹术可以减少额外的瘢痕组织,但与标准修复术相比,它并不会改变神经再生或功能改善的速度。使用某些移植物选项时,您可能会更早地感受到缓解,但完全恢复需要时间。

实际发生了什么

您的神经就像包裹着保护性绝缘层的电线。当神经被切断或拉伸时,身体会尝试通过形成瘢痕组织来修复它。这种瘢痕组织可能会阻碍信号的传导,导致您出现麻木或无力。在某些情况下,如缺损在 3 厘米或更小的情况下,您的外科医生可能会使用一种由胶原蛋白制成的特殊管道来桥接断裂处。这种管道就像一条隧道,引导神经纤维重新连接,而无需从身体的其他部位取组织。

对于更大或更复杂的神经损伤,您的外科医生可能会使用供体神经。这是恢复较大缺损处运动功能的最佳选择。虽然胶原蛋白管道在恢复手指感觉方面效果良好,但供体神经在恢复肌肉力量方面通常更好。随着时间的推移,身体会用一层薄膜包裹这些材料,类似于身体用绷带包裹伤口的方式。

这些修复的目标是帮助您的神经顺利愈合,从而恢复功能。有时,身体的愈合过程会产生过多的瘢痕组织,这可能导致疼痛或僵硬。在这种情况下,您的外科医生可能会使用由猪组织制成的包裹物来减少瘢痕形成。这种包裹物有助于神经愈合,虽然它本身并不能提高修复速度,但它能保持该区域清洁和稳定,以便您的身体发挥最佳修复作用。

我们能做什么

您的治疗通常从自我管理和物理治疗开始。您的外科医生可能会推荐一些练习,以保持关节活动并减轻僵硬。您将与物理治疗师合作,以增强神经周围的肌肉力量。这种方法旨在通过非手术方式减轻压力。在考虑其他步骤之前,您应该给这个计划一个充分的机会。

如果疼痛持续存在,您的外科医生可能会建议药物治疗。这可能包括止痛药或抗炎药,以帮助您缓解不适。在某些情况下,可能会提供注射治疗,如皮质类固醇、透明质酸或富血小板血浆(PRP)。这些注射可以减少肿胀并安抚神经。它们提供的缓解效果因人而异,但通常用于在愈合发生之前起到过渡作用。

当保守治疗达到极限时,才会考虑手术。如果您的症状没有改善,或者神经间隙太大而无法进行简单修复,您的外科医生会与您讨论这一选项。手术可能涉及使用神经包裹物或神经导管来桥接神经中的间隙。当直接修复不可行时,这些工具可以帮助引导神经自我愈合。

何时就医

若休息后疼痛仍持续不缓解,请咨询您的全科医生。若发现手部无力或不稳,请要求专科医生评估。若关节出现交锁或打软腿,请联系您的外科医生。若症状干扰您的睡眠或工作,请寻求帮助。若病情突然加重,也应寻求医疗帮助。这些体征可能表明需要进一步治疗,例如二次减压联合神经包裹术。您的外科医生将评估您是否需要使用神经导管来桥接 3 厘米或更短的缺损。

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. The following considerations are for informational purposes only, are not exhaustive, and do not form part of our licenses.

Considerations for licensors: Our public licenses are intended for use by those authorized to give the public permission to use material in ways otherwise restricted by copyright and certain other rights. 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. More considerations for licensors: wiki.creativecommons.org/Considerations_for_licensors

Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. 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.

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.

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.
