屈肌腱鞘囊肿 资料 In-depth
您的症状
您的手掌中有一个小而坚硬的肿块,通常位于手指根部附近。它位于弯曲手指的肌腱隧道上方。该肿块为腱鞘囊肿,是一种源自该肌腱隧道衬里的充满液体的囊袋。触摸时,它可能感觉像皮肤下的豌豆。
肿块可能会引起疼痛,尤其是在抓握或挤压时。按压它可能会感到不适。需要用力弯曲手指并压迫肿块的动作可能会引起疼痛,例如握方向盘、提购物袋或手持工具。有些人发现,在手部大量使用后,肿块会更加明显。
此部位的肿块容易与其他病症混淆。扳机指(手指弯曲时出现卡顿或弹响)的感觉可能相似。杜普伊特伦病(一种组织索带将手指拉向手掌的疾病)也可能有类似表现。您的外科医生将检查肿块,并确定您患有哪种情况。超声等扫描检查有助于确认肿块的性质。
腱鞘囊肿通常会随时间发生变化。许多囊肿会自行缩小,但这可能需要数年。有些囊肿大小保持不变或缓慢增大。可以用针头抽出肿块内的液体,这通常能暂时缓解症状,但肿块通常会复发。手术切除整个肿块的复发率较低。
如果肿块引起疼痛或造成不便,有多种有效的治疗选择。通常首先尝试抽吸液体。如果肿块持续困扰您,手术切除肿块也是一种有效的选择。
实际发生了什么
您的手指之所以能弯曲,是因为有一根肌腱——一根从您的前臂沿手掌延伸至手指的强韧绳索。这根绳索在一个称为腱鞘的紧密隧道中滑动。该隧道的内衬会分泌少量液体,其作用类似于铰链中的润滑油,使肌腱能够顺畅滑动。
腱鞘囊肿始于该内衬的一部分向外膨出并充满浓稠、透明的液体。这有点像在隧道壁上形成一个小水泡。囊袋与隧道保持连接,这就是为什么用针抽出液体并不总能治愈它。只要这种连接存在,囊袋就可能再次充满。
肿块本身是无害的,但它占据了空间有限的区域。这就是为什么抓握或挤压可能会引起疼痛:肿胀的囊袋压迫周围的组织。同样的空间拥挤也解释了为什么此处的肿块可能靠近导致手指弹响或卡顿的结构,以及为什么您的外科医生会仔细检查您具体患有哪种疾病。
大多数此类肿块随时间推移表现稳定。有些肿块会自行缩小或消失。有些人天生更容易长这种囊肿,而关节松弛的腕部似乎会使腱鞘囊肿的发生率更高。如果通过手术切除,同一部位复发的几率约为10%。
需要了解的关键点是这个肿块不是什么。它不是癌症,也不会扩散到身体的其他部位。它是您手部已存在的内衬所形成的一个液囊。理解这一点可以让接下来的选择感觉不那么令人畏惧:观察等待、抽吸或切除。
我们如何处理
Mater Private Hospital Rockhampton 的上肢外科医生 Kieran Hirpara 医生会从适合您病情的最微创方案入手。患者通常由全科医生转诊至我们的诊所;如果理疗师建议您就诊,您仍需获得全科医生的转诊才能符合 Medicare 报销资格。在首次就诊时,我们会仔细询问病史,检查肿块,并在必要时安排超声等扫描以帮助确认其性质。
正如上文所述,许多此类肿块会自行消退。如果您的肿块不痛且不影响活动,我们可能仅进行观察。改变抓握或持握工具的方式可以减轻对肿块的压迫。手部治疗旨在保持手指舒适地活动,并在您使用手部时缓解酸痛。
通常首先尝试用针头抽出液体。针头将囊内的浓稠液体抽出,使肿块暂时消退。由于与腱鞘的连接通常保持开放,肿块往往会再次充盈。我们会在手术前与您讨论这一步骤,因为它可能使部分患者避免手术。
如果经过上述步骤后肿块仍持续困扰您,我们会讨论通过手术将其切除。手术会切除整个囊及其与腱鞘的连接,从而降低复发的可能性。任何手术都会留下疤痕并存在一定并发症风险,我们会与您详细说明这些情况。对于部分患者,手术在缓解疼痛或改善手部功能方面,效果并不比保留肿块更好,因此我们会共同权衡利弊。
预期情况
这些肿块大多发展过程平稳。部分肿块大小保持不变,少数会缓慢增大。疼痛感通常随手部使用程度而时隐时现。
若不对肿块进行处理,其自行消退的可能性确实存在,但这可能需要数年。抽出液体通常能暂时缓解症状,但大多数腱鞘囊肿在抽液后会复发。通过手术切除肿块可降低复发率,接受手术的患者在6周内报告手部功能改善且疼痛减轻。手术并不能保证手部完全无痛,且对部分患者而言,其效果与不处理肿块相当。
若肿块被切除且未复发,大多数人可恢复正常生活。疤痕会在数月内稳定下来。部分肿块即使在仔细切除后仍可能在原处复发,因此我们将在您的随访就诊时检查该区域。若发生这种情况,您和您的外科医生可以讨论下一步的处理方案。
何时就医
大多数此类肿块是无害的,可以等待常规预约就诊。如果肿块疼痛、增大,或影响您的抓握功能或日常活动,请咨询您的全科医生。如果手指弯曲时出现卡顿或弹响,或手指向手掌方向牵拉,请要求专科医生评估,因为这些可能是需要不同治疗的另一种疾病的迹象。如果手部变得发热、发红和肿胀,或出现发热,请前往急诊科,因为感染需要当天处理。如果您注意到拇指或手指出现新的麻木、针刺感或无力,请寻求紧急评估,因为肿块压迫神经如果拖延太久可能会导致永久性问题。
深入探讨
Advanced reading: the deeper science (optional)
本节内容超出了您做出自身治疗决策所需的深度。屈肌腱鞘腱鞘囊肿值得额外阅读,因为它是手部外科中最小的肿块,却能可靠地引发不成比例的症状;并且,其附着部位决定了疼痛的原因以及简单治疗失败的原因。
豌豆大小且疼痛与体积不成比例的肿块
这些囊肿也称为腱鞘囊肿或掌侧腱鞘囊肿,起源于将屈肌腱固定在指骨上的纤维鞘[1]。它们位于手掌中手指的基部,通常直径仅几毫米,质地坚硬而非柔软。
其症状具有特征性,一旦解剖结构清晰便不言自明:在紧握坚硬且狭窄的物体(如方向盘、高尔夫球杆、自行车把手、购物袋提手)时出现疼痛。囊肿被夹在物体与下方的骨骼之间,由于鞘直接附着于指骨,缺乏软组织缓冲。
这就是为什么肿块大小与症状相关性极差的原因。手腕背侧较大的柔软肿胀可能无痛,而手指基部仅为其几分之一大小的病变却可能真正造成活动受限。
与其他所有腱鞘囊肿相同的规则
其生物学行为取决于其所连接的结构。囊肿起源于腱鞘,并由其充盈,这意味着其力学机制与腕部腱鞘囊肿及黏液囊肿相同:囊袋是问题的可见末端,而非源头。
因此,穿刺或抽吸仅针对肿胀,而非渗漏。单纯引流后复发常见,确定性治疗需切除囊肿及其起源的受累腱鞘部分。
为何该手术听起来较小但并非微不足道
切除术是通过手指基底部的小切口进行的短程手术,通常具有治愈性。该部位的两个解剖学事实使得谨慎操作至关重要。
指神经紧邻屈肌腱鞘走行,每侧各有一支,且在手指基底部,它们位置表浅,靠近正在被切除的中线结构。手指一侧边缘出现麻木斑块是此部位小型手术的一个已知风险。
其次,只能切除腱鞘的冗余部分。将肌腱固定在骨骼上的滑车是承重结构,失去关键的滑车会导致肌腱弓弦样脱离手指,从而削弱抓握力。因此,切除术被刻意限制在不执行该功能的腱鞘节段。
何时不予处理
由于该病变为良性且不会无限增大,治疗仅由症状驱动。若囊肿明显但日常抓握时不引起疼痛,则无需任何处理。若进行治疗,是因为特定且重复的活动受到损害,这比大多数情况下的指征更为明确,因为诱发症状的抓握动作通常易于患者识别。
指间关节和腕部的相关囊肿将在各自的页面中单独介绍;这三者共同的原则是,决定问题是否复发的因素是囊蒂,而非囊体。

Anatomy & Pathophysiology
Anatomical Location and Origin
- Volar wrist ganglia tend to arise in the interval between the first extensor compartment and the flexor carpi radialis (FCR) tendon sheath, just proximal to the wrist flexion crease [7].
- Approximately two thirds of anterior wrist ganglions reportedly arise from the radiocarpal joint [7].
- One third of anterior wrist ganglions reportedly arise from the scaphotrapezial joint [7].
- Ganglion cysts that arise from the FCR sheath are often located slightly more medially, either just radial or palmar to the sheath [7].
- Ganglions arising from the FCR sheath are typically less mobile than ganglions arising from the wrist joint [7].
- Ganglions arising from the first extensor compartment tend to adhere to the sheath (extensor retinaculum) and are less mobile [7].
- Ganglions are defined as cystic swellings closely connected to joints or tendon sheaths which contain mucinous material [64].
Clinical Presentation and Physical Characteristics
- Volar wrist ganglia typically appear to be 1 to 2 cm in size but may be significantly larger at the time of surgical dissection [7].
- Patients with volar wrist ganglions often present with a mass that has been present for a number of months or years and is typically asymptomatic [7].
- Patients with volar wrist ganglions often note discomfort when the mass is "bumped" [7].
- Clinically, volar wrist ganglia are compressible, slightly mobile, nontender, and visible when transilluminated [7].
- Volar wrist ganglia are nonpulsatile but are often intimate with the radial artery, which is palpable alongside the lesion [7].
- Most patients with intraneural ganglions are aged 30 to 50 years, though occurrence in children has also been reported [11].
- Most patients with intraneural ganglions present with a painless mass [11].
- Some patients with intraneural ganglions present with symptoms of nerve irritation or entrapment neuropathy [11].
Pathogenesis and Etiology
- The etiology of ganglions is unknown [64].
- Many hypotheses have been advanced for the pathogenesis of ganglions, including retention cyst, herniation of tendon or capsular synovia, bursal transformation, neoplasia, and mucinous degeneration of fibrous tissue [64].
- Carp and Stout reported that a ganglion does not initially connect with the joint and that communication occurs secondary to degeneration of the capsule which then ruptures [64].
- Injections of contrast material into ganglions usually fail to show a communication into the joint [64].
- Injections of contrast material into the wrists of patients have demonstrated communications into the ganglions [64].
- In forty of fifty-nine patients with ganglions in the study by Andrén and Eiken, contrast medium passed from the joint into the ganglion through a tortuous narrowed duct [64].
- The articular (synovial) theory has gained worldwide acceptance as a scientifically proven explanation for the formation of intraneural ganglions [11].
- The pathogenesis of intraneural ganglion cysts remains unclear, though trauma has been proposed as a possible reason [77].
- The theory of articular unification is mainly accepted as the cause for intraneural ganglion cysts [77].
Nerve Involvement
- Involvement of the peripheral nerves of the upper extremity by intraneural ganglion is rare [11].
- The ulnar nerve is the most commonly involved nerve in the upper extremity by intraneural ganglion [11].
- Almost any other nerve in the vicinity of a joint can be involved by intraneural ganglion [11].
- Intraneural ganglion cysts are benign, mucinous, non-neoplastic lesions of the peripheral nerves [77].
Classification
- Volar wrist ganglia tend to arise in the interval between the first extensor compartment and flexor carpi radialis (FCR) tendon sheath, just proximal to the wrist flexion crease [7].
- Ganglion cysts that arise from the FCR sheath are often in a slightly more medial location, either just radial or palmar to the sheath [7].
- Ganglions arising from the first extensor compartment tend to adhere to the sheath (extensor retinaculum) [7].
- Ganglions arising from the first extensor compartment tend to be quite firm and are less mobile [7].
- The proposed classification of ganglia helps minimize the area of resection required [50].
Clinical Presentation
General Characteristics
- Volar wrist ganglia are typically asymptomatic masses that have been present for months or years [7].
- Patients with volar wrist ganglions often report discomfort when the mass is bumped [7].
- Clinically, volar wrist ganglions are compressible, slightly mobile, nontender, and visible when transilluminated [7].
- Volar wrist ganglions are nonpulsatile but are often intimate with the radial artery, which is palpable alongside the lesion [7].
- Ganglion cysts arising from the flexor carpi radialis (FCR) sheath are often located slightly more medially, either just radial or palmar to the sheath [7].
- Ganglions arising from the first extensor compartment tend to adhere to the sheath, are quite firm, and are less mobile [7].
Epidemiology and Demographics
- Women are significantly more likely to be diagnosed with a volar wrist ganglion, regardless of age or military status [6].
- Pediatric ganglions more commonly have a tendon sheath origin compared to adults [4].
- In children aged less than 10 years, ganglion cysts present on the volar aspect of the wrist [15].
- In patients aged greater than 10 years, ganglions resemble those in the adult population and present on the dorsal aspect of the wrist [15].
- Ganglions in pediatric populations demonstrate a female predilection [26].
Imaging and Diagnosis
- Routine wrist radiography is not cost-effective in the evaluation of patients with a wrist ganglion due to a low prevalence of therapeutically significant findings [16].
- MRI provides relatively good reliability in establishing the diagnosis of an occult dorsal wrist ganglion, with a sensitivity of 83% when using intra-operative findings as the standard [27].
- MRI is an excellent diagnostic modality to evaluate rapidly growing upper extremity masses and distinguish ganglions from malignant processes [20].
- The 3-dimensional FSE extended echo train MRI sequence (cube) provides better visualization of intraneural ganglions and articular connections to the cyst [11].
Investigations
- Radiologists are less likely to identify occult dorsal ganglion cysts on MRI if the cyst is smaller or if the requisition form does not mention a cyst [63].
- Recent advances in MRI technology, specifically the 3-dimensional FSE extended echo train sequence called cube, have revolutionized the visualization of intraneural ganglions and the articular branches that connect them to the joint [11].
- High-resolution MRI techniques have the potential to improve patient outcomes by allowing better preoperative planning and more accurate surgical intervention [11].
- Routine wrist radiography is not cost-effective in the evaluation and treatment decision-making process for patients with a wrist ganglion due to a low prevalence of therapeutically significant findings [16].
- Sonography-guided wrist arthroscopy provides visualization of the ganglions and ganglion stalk, as well as of the arthroscopic shaver and adjacent structures such as nerves, vessels, and tendons [54].
- Sonography-assisted arthroscopic resection is a safer and more reliable method for treating volar wrist ganglia [30].
- A careful physical examination is essential to direct care and future testing if indicated, as diagnostic tests such as imaging can be expensive, time consuming, and often nonspecific [23].
Non-Operative Management
- Nonsurgical treatment is largely ineffective in treating ganglion cysts, though it may be considered for symptomatic relief in patients who do not want surgery [55].
- No recurrences were observed after a second puncture in the cohort assessed for percutaneous puncture of flexor tendon sheath ganglions [2].
- Most ganglions recur after aspiration [18].
- There is no consensus within the literature regarding the best management of pediatric wrist ganglia, and no single treatment modality confers a particular advantage or disadvantage over another [9].
Operative Management
- Open surgical excision offers significantly lower chance of recurrence compared with aspiration in the treatment of wrist ganglions [62].
- Surgical intervention has about a 10% recurrence rate, leaves scars, and has some risk for adverse events [18].
- Arthroscopy allows for the simultaneous treatment of ganglions and other pathologies [10].
- The outcomes, recurrence, and complications rates after 4 years of follow-up support the use of arthroscopy as a treatment for dorsal wrist ganglion [12].
- At 12 months follow-up, the rates of recurrence with arthroscopic dorsal ganglion excision are comparable with and not superior to those of open excision [17].
- Arthroscopic resection is an effective treatment strategy for intra-articular synovial ganglions refractory to conservative measures, providing complete resolution of symptoms and functional recovery with minimal soft tissue damage [51].
- Arthroscopic ganglionectomy through an intrafocal cystic portal is a safe and efficacious option for the treatment of painful wrist ganglia [52].
- Recurrent ganglion cysts originating from the midcarpal joint are not contraindications for arthroscopic resection [22].
- In patients with the clinical diagnosis of wrist ganglion cyst, the quality of care would not be compromised by abandoning the practice of routine submission of surgical specimens for pathological examination after excision of the ganglion cyst [13, 25].
Outcomes and Complications
- Recurrence of the wrist ganglion cyst occurred in five patients (9%) in a cohort of 53 patients undergoing arthroscopic resection [49].
- PRWE scores were significantly higher in patients with a recurrence (30 vs. 12, p = 0.002) following arthroscopic resection [49].
- Patients initially presenting with a new ganglion cyst had fewer recurrences at final follow-up compared with patients initially presenting with recurrence (4 vs. 15%, respectively) [49].
- Three of the 53 patients (6%) had a complication following arthroscopic resection of wrist ganglion cysts [49].
- One patient experienced neuropraxia of the radial superficial nerve, which resolved spontaneously [49].
- One patient developed extensor carpi ulnaris (ECU) tendinitis which was successfully treated with splinting [49].
- One patient experienced painful scar tissue, which was successfully removed surgically [49].
- Worse hand function was associated with recurrence following prior surgery, worse baseline hand function and lower treatment credibility [28].
Complications
- Surgical excision of flexor tendon sheath ganglions is considered a safe method with no specific complications reported in the cited study [1].
- Percutaneous puncture of flexor tendon sheath ganglions has a low recurrence rate, with no recurrences observed after a second puncture in the studied cohort [2].
- Volar wrist ganglions arising from the first extensor compartment or flexor carpi radialis (FCR) sheath may be difficult to distinguish from anterior wrist joint ganglions [7].
- Ganglion cysts arising from the FCR sheath are typically less mobile than ganglions arising from the wrist joint [7].
- Ganglions arising from the first extensor compartment tend to adhere to the sheath and are less mobile [7].
- Operation-related complications after arthroscopic volar wrist ganglionectomy are associated with the anatomical location of the cyst, specifically when it is distal to the bifurcation of the radial artery and concurrently penetrated up to the superficial fascia layer [21].
- Surgical intervention for wrist ganglions has a recurrence rate of approximately 10% [18].
- Surgical intervention for wrist ganglions leaves scars and carries some risk for adverse events [18].
- Open dorsal wrist ganglion excision in patients whose occupation or activities require forceful wrist extension is associated with a considerable risk of residual pain and functional limitations [70].
- Arthroscopic resection of dorsal wrist ganglions has recurrence and complication rates that support its use as a treatment option [12].
Recovery
- Surgical excision of a painful ganglion of the digital flexor tendon sheath is a simple, safe, and effective method [1].
- Percutaneous puncture for flexor tendon sheath ganglions has a low recurrence rate, with no recurrences observed after a second puncture in the studied cohort [2].
- Endoscopic ganglionectomy via flexor carpi radialis tendoscopy offers better cosmesis and less soft tissue trauma compared to other approaches [3].
- In children with a wrist ganglion, if the cyst resolves spontaneously, it usually does so within 18 months [14].
- In children aged <10 years, volar wrist ganglions are generally amenable to observation with spontaneous regression [15].
- Open surgical excision for pediatric wrist ganglions demonstrates a relatively low recurrence rate with minimal complications [15].
- Approximately 40% of wrist ganglion lesions decrease over the first 6 years after evaluation by a hand surgeon [18].
- Surgical intervention for wrist ganglions has about a 10% recurrence rate [18].
- Surgical intervention for wrist ganglions leaves scars and has some risk for adverse events [18].
- Routine midcarpal joint exploration during arthroscopic excision of dorsal wrist ganglions appeared to reduce recurrence at 1 year without negatively impacting patient outcomes [29].
- Complete resection of the ganglion stem and complete closure of the joint capsule is the most important step to avoid recurrences [71].
