桡管综合征 资料

本页面由机器翻译，尚未经临床医生审核。英文版本为权威版本。

您的感受

您可能会注意到肘部外侧出现深部的酸痛。这种不适感通常会沿着前臂背侧向手腕和手部放射。与其他神经问题不同，在此阶段您通常不会感到手部无力。相反，主要症状是持续性疼痛，且难以精确定位到某一具体部位。

当您对抗阻力伸展腕关节或手指时，疼痛往往会加重。在抓握物体、转动门把手或掌心向下提举物品时，您可能会感到疼痛加剧。需要重复手臂活动的活动（如打字或园艺）可能诱发疼痛发作。酸痛在夜间也可能变得更加明显，导致难以找到舒适的睡眠姿势。

随着不适感加剧，日常活动可能变得具有挑战性。简单的动作，如伸手到背后扣内衣或塞衬衫下摆，可能会引起尖锐的刺痛或钝痛。您可能会为了避免某些动作以保护手臂，这可能导致随着时间的推移出现僵硬。虽然休息通常能提供一定的缓解，但疼痛可能会持续存在并干扰您的日常生活。

如果保守措施无法缓解您的症状，我们将讨论进一步的选项。我们的方法侧重于确定刺激的来源，以指导您的康复。我们旨在通过为您量身定制的计划，帮助您恢复舒适感和功能。

实际发生了什么

桡管综合征是由于桡神经在沿手臂下行过程中受到压迫所致。该神经穿过前臂中一个狭窄的通道，称为桡管。可以将这个通道想象成一个紧身的袖套。当周围组织肿胀或收紧时，就会对神经产生压迫。这种压力会阻碍神经向肌肉发送清晰的信号。

桡神经控制着抬起手腕和手指的肌肉，并为手背提供感觉。当神经受压时，您可能会感到肘部和前臂外侧深处疼痛。当您试图在抗阻情况下伸直手腕时，这种疼痛通常会加重。您可能还会注意到握力减弱或提举物体困难。这些症状的发生是因为神经在压力下难以与肌肉进行有效沟通。

您的外科医生会寻找这种压迫发生的具体位置。没有任何一种单一的手术入路能够完全显露并松解桡管内所有潜在的压迫点。因此，仔细的检查至关重要。如果保守治疗无效，可能会建议手术以解除神经压迫。其目的是创造更多空间，使神经能够再次自由移动。

在某些情况下，该问题与其他肘部疾病有关。例如，肘关节僵硬有时源于神经刺激。如果您因肘关节僵硬接受手术，您的外科医生会检查是否存在任何神经受累情况。即使术前您的神经功能看似正常，也可能考虑进行预防性神经松解。这有助于预防未来的并发症，并确保手臂运动和力量获得最佳恢复。

我们能采取的措施

基兰·希尔帕拉（Kieran Hirpara）医生是麦特私人医院（Mater Private Hospital Rockhampton）的上肢外科医生，他所采取的方法反映了我们在诊所中对该疾病的管理方式。我们通常从非手术治疗开始。这一步骤侧重于休息和活动调整，以减轻前臂的负担。物理治疗旨在增强手臂和手腕的力量与灵活性。我们通常建议在进行其他选择之前，先充分尝试这种保守治疗。

药物治疗有助于在愈合过程中控制疼痛和炎症。您的外科医生可能会建议使用抗炎药物来减少神经周围的肿胀。在某些情况下，我们会讨论注射治疗。皮质类固醇注射可以减轻炎症，尽管效果是暂时的。透明质酸或富血小板血浆（PRP）注射是您的外科医生可能会讨论的其他选择，以支持组织健康。这些治疗旨在缓解症状并改善功能，而无需进行手术。

当非手术治疗未能提供足够的改善时，会考虑手术治疗。对于结构性或急性问题（例如骨折导致的神经损伤），在没有先进行非手术试验的情况下，我们也建议立即进行手术。手术减压涉及释放对桡神经的压力。这是针对对保守治疗无反应的病例的可行选择。在特定情况下，例如肘关节置换术中水泥导致的神经损伤，立即移除水泥并进行神经松解可能有助于恢复。对于长期存在的神经损伤且神经无法修复的情况，可能会使用肌腱转移来恢复手部功能。我们会与您讨论这些选项，以确保计划符合您的需求。

预期情况

对大多数人而言，桡管综合征无需手术即可改善。70%–88% 的桡神经损伤可自发恢复。这意味着您的症状可能会随时间自行缓解。初始非手术治疗是标准的第一步。您的外科医生将指导您进行保守治疗，以帮助神经愈合。

如果您的症状在保守治疗后没有改善，手术可能是一个选项。手术减压可解除对桡神经的压力。这通常仅保留用于在其他治疗后仍持续疼痛的病例。手术后的预后取决于多种因素，包括您出现症状的时间长短以及神经受压的具体原因。

恢复是一个渐进的过程。如果需要手术，您的外科医生将致力于减轻对神经的压力。您可能会在数周至数月内注意到感觉或力量的变化。在某些情况下，例如与骨折相关的损伤，在受伤后 3 周内进行早期手术探查可提高恢复神经功能的可能性。然而，即使进行干预，也不能保证每个人都能完全康复。

保持现实的期望非常重要。虽然许多患者会经历显著改善，但有些人可能会继续存在残留症状。治疗的目标是尽可能减轻疼痛并恢复功能。您的外科医生将根据您的具体情况以及对初始治疗的反应，与您讨论具体的预后。

如果神经损伤严重或病程较长，可能会考虑肌腱转移等额外手术。这些手术通过重新排列肌腱来帮助恢复功能。这通常被视为不可修复神经病变的最后手段。然而，大多数患者通过非手术方法或标准减压手术获得缓解。

我们将支持您度过这一过程的每一个阶段。我们将密切监测您的进展，并根据需要调整您的护理计划。我们的目标是帮助您以最小的不适感回归日常生活。如果您对接下来会发生什么有疑问，请随时提问。

何时就医

若外侧肘部或前臂持续疼痛且休息后无改善，请咨询全科医生。若发现腕部或手指无力，或症状干扰睡眠或工作，请要求专科医生评估。疼痛或麻木突然加重也需及时就诊。尽管许多桡神经损伤可在3至5个月内自行恢复，但早期评估至关重要。与等待观察相比，在受伤后3周内进行手术探查与显著更高的桡神经功能恢复率相关。非手术治疗是桡管综合征的一线治疗方法，但及时评估可确保您获得正确的治疗。

  • Surgical decompression of the median nerve or the anterior interosseous nerve (AIN) in the forearm is rarely indicated, and a prolonged nonsurgical approach is warranted in most cases [19].

Anatomy & Pathophysiology

  • It is important to understand the anatomic course and distribution of the radial nerve to make an accurate diagnosis [9].
  • The posterior interosseous nerve crosses the radial head midline and increases its distance from bony structures with supination of the forearm [26].
  • Supination increases the linear distance between the posterior interosseous nerve and the radial head, which should be considered to increase safe working volume during intra-articular procedures on the anterolateral aspect of the elbow [26].
  • The distance of the posterior interosseous nerve from the radial head appears to increase with forearm supination, potentially increasing safe working space [31].
  • Predictive accuracy for posterior interosseous nerve localization in the proximal forearm is highest when the arm is in a supinated position [32].
  • The posterior interosseous nerve moves farther from the radial head during elbow extension than flexion [35].
  • The posterior interosseous nerve moves farther from the radial head during forearm pronation than supination [35].
  • Distal migration of the posterior interosseous nerve is minimal (3.5 mm) across various elbow and forearm positions [35].
  • Wrist proprioception appears to be a multifactorial phenomenon [34].
  • There is controversy surrounding radial tunnel syndrome, dynamic compression theories, and the difficulty in differentiating it from tennis elbow [37].

Classification

  • Radial tunnel syndrome is traditionally defined as a pain syndrome caused by compression of the posterior interosseous nerve at the proximal forearm [7].
  • Radial tunnel syndrome and posterior interosseous nerve compression are distinct entities with different clinical presentations but share identical potential sites of nerve interference [12].
  • Radial tunnel syndrome and posterior interosseous nerve compression are proposed to be mild (radial tunnel syndrome) and severe (posterior interosseous nerve compression) forms of one disease to simplify nomenclature [12].
  • MR imaging features provide credence to the concept that radial tunnel syndrome is a distinct clinical entity related to compression of the posterior interosseous nerve [10].
  • The issue surrounding radial tunnel syndrome traditionally has been properly identifying it clinically [1].
  • It is important to understand the anatomic course and distribution of the radial nerve in order to make an accurate diagnosis [9].
  • Nomenclature advocates for consistent use of terminology distinguishing the deep branch of the radial nerve and the posterior interosseous nerve [17].
  • Radial tunnel syndrome and posterior interosseous nerve syndrome are recommended to be viewed as a single condition presenting along a spectrum of nerve entrapment [17].

Clinical Presentation

  • Radial tunnel syndrome is traditionally characterized by difficulty in proper clinical identification [1].
  • Radial tunnel syndrome is an illness construct based on speculative pathophysiology with no verifiable pathophysiology or accepted reference standard for diagnosis [2].
  • There is ongoing controversy regarding the diagnosis and outcomes of radial tunnel syndrome [3].
  • Radial tunnel syndrome is a pain syndrome caused by compression of the posterior interosseous nerve at the proximal forearm [7].
  • Radial tunnel syndrome and posterior interosseous nerve compression are distinct entities with different clinical presentations [12].
  • Radial tunnel syndrome and posterior interosseous nerve compression share identical potential sites of nerve interference [12].

  • Understanding the anatomic course and distribution of the radial nerve is important for making an accurate diagnosis [9].
  • Radial tunnel syndrome and posterior interosseous nerve syndrome may be viewed as a single condition presenting along a spectrum of nerve entrapment [17].

Investigations

  • Radial tunnel syndrome is traditionally identified through clinical evaluation [1].
  • MR imaging provides credence to the concept that radial tunnel syndrome is a distinct clinical entity related to compression of the posterior interosseous nerve [10].
  • Dynamic ultrasonographic assessment of changes in the anteroposterior diameter and cross-sectional area is an effective diagnostic tool for identifying radial tunnel syndrome [18].
  • Neuroimaging should be considered as a complementary diagnostic method in posterior interosseous neuropathy syndrome [33].

Treatment

Non-Operative Management

  • Nonsurgical management is the first-line treatment for radial tunnel syndrome [3].
  • A prolonged nonsurgical approach is warranted in most cases of nerve compression syndromes in the forearm, such as ulnar tunnel syndrome, radial tunnel syndrome, anterior interosseous nerve syndrome, and pronator syndrome [19].
  • Nonoperative management with corticosteroid injection can be used as a therapeutic measure with potential long-term benefits in the treatment of radial tunnel syndrome [27].
  • Prospective evaluation of a single corticosteroid injection demonstrated improvement in standardized outcomes measures of pain and function at one year in 75% of patients presenting with symptoms of radial tunnel syndrome [5].

Operative Management

  • Surgery is advocated for high radial nerve entrapment neuropathy cases resistant to conservative treatment, emphasizing the importance of dissecting the entire length of the fibrous tunnel [6].
  • No single surgical approach was adequate for complete visualization and release of all compression points of the radial tunnel [13].

Complications

  • Isolated posterior interosseous nerve neurectomy (PINN) has shown excellent clinical outcomes, with few patients experiencing recurrent pain at long-term follow-up [21].

Recovery

  • Surgical decompression is a viable option for refractory cases of radial tunnel syndrome [3].
  • In a case of posterior interosseous-nerve syndrome secondary to rheumatoid synovitis with entrapment duration of more than two years, a tendon transfer was used as treatment [38].
  • Surgical excision can lead to rapid recovery of nerve sensation in cases of radial nerve compression by ganglion cysts [39].
