手部和手臂的麻木与刺痛 资料
您的感受
手部和手臂的神经问题会导致刺痛、麻木或针刺感。您可能会在拇指、手指、手掌或前臂注意到这种感觉。有些人会感到沿神经路径的钝痛。症状通常在夜间或刚醒来时加重。长时间保持手腕弯曲的姿势(例如阅读或驾驶时)可能会使症状恶化。甩动手部可能会带来短暂的缓解。
日常任务可能会变得更加困难。您可能会在扣纽扣时笨拙、打翻咖啡杯,或在拧开罐盖时感到吃力。长时间打字或使用手机可能会引发刺痛感。有些人会注意到手指感觉笨拙或无力。当感觉迟钝时,精细的手指动作(如穿针引线)可能会变得困难。
症状出现的位置提示了哪条神经受到刺激。正中神经从前臂延伸至拇指、食指、中指以及无名指的一半。尺神经向下延伸至小指以及无名指靠近小指的一半。对其中任何一条神经的压迫都会导致其相应皮肤区域的麻木。有时,一条神经上的两个位置同时受到挤压,这可能会使症状更加严重。
神经症状也可能发生在受伤或其他手术之后。手部损伤可能直接损伤神经,导致一块皮肤感觉麻木或愈合缓慢。即使手术部位远离手部,肩部或颈部手术后有时也会出现神经问题。神经附近的肿胀或瘢痕组织可能会压迫神经,引起相同的刺痛感。
如果您的症状较轻,通过休息或使用夹板等简单措施可能会缓解。如果症状持续存在,您的医生可以检查您的手部并确定受累的神经。神经检查或超声扫描等测试可以确认病因。找到正确的压迫点至关重要,因为治疗在针对正确的神经时效果最佳。
实际发生了什么
您的神经就像从颈部延伸至指尖的电线。它们传递感觉和运动信号。当神经经过手腕或肘部的狭窄通道时,可能会受到挤压。想象一下被门夹住的水管:水仍然流动,但很微弱。受挤压的神经工作原理相同,因此您感觉到的刺痛和麻木是神经信号微弱地通过所致。
长时间的压力会改变神经本身。首先,神经的保护性外膜会变得发炎和渗漏。如果挤压持续,内部的“电线”开始磨损。神经损伤的严重程度决定了您的感受。轻度发炎的神经在压力缓解后会恢复。严重受损的神经可能导致麻木,改善所需时间更长,或者无法完全恢复。
有时,单一的挤压点并非全部原因。同一神经上的两个受压点,例如肘部和手腕,可能会叠加。这被称为双重挤压:每个点单独可能不会引起问题,但合在一起就会。当症状轻微时,无需手术,缓解两个受压点可能就足够了。
您的姿势也可能起作用。长时间将手臂或手腕保持在别扭的位置,可能会压迫或拉伸神经。保持在缩短位置的肌肉会减弱,其他肌肉则需超负荷工作以弥补。
您感觉刺痛的位置指向哪条神经受到挤压。正中神经受压会导致拇指、食指、中指以及无名指靠拇指一侧麻木。尺神经受压会影响小指以及无名指靠近小指的一半。您的医生会将您的症状与正确的神经相匹配,因为治疗在针对正确部位时才有效。
我们可以采取的措施
在考虑任何手术程序之前,您可以尝试许多方法。让手部休息并改变使用方式可以减轻神经的压力。手部治疗师可以教您进行锻炼和神经滑动练习,即让神经在其通道内轻柔地移动。脱敏训练、按摩和保护性手套也可以缓解受刺激的皮肤和神经。简单的感觉练习易于在家完成,并可融入常规治疗方案中。请给予这些措施数周的充分尝试。早期干预至关重要:尽早发现神经问题可以防止僵硬和无力变得固定。
药物可以配合这些步骤发挥作用。调节疼痛的药物可以降低神经引起的灼烧感或刺痛感。有些人发现,低剂量的某些抗抑郁药或其他镇静神经的药物有助于他们在症状发作时整夜安睡。这些药物作用于疼痛通路,而非神经受压本身。对于某些病症,合适的压力手套可以减少因手部下垂或用力工作而加重的肿胀。您的医生会权衡每种方案的益处与可能的副作用,并力求使用能起效的最低剂量。在考虑任何手术之前,强效阿片类止痛药通常不是好的选择。
如果尽管采取了这些措施,症状仍然严重,建议咨询专科医生。您的医生可以检查您的手部,检查颈部,并测试受累的神经。神经电生理检查或超声扫描可以精确定位压力点。关于您的症状和日常活动的详细问卷有助于跟踪您的恢复情况。在此基础上,您的医生将讨论手术程序是否可能有助于解决您特定的神经问题。并非每个病例都需要手术,决策取决于检查结果以及您的症状对您造成的限制程度。
预期情况
神经症状通常遵循一定的模式。轻微症状可能通过休息、支具固定以及改变手部使用方式而缓解。当症状较轻时,无需手术即可通过减轻压迫来改善。早期干预至关重要:尽早发现神经问题可以防止僵硬和无力症状的出现。
如果神经受压持续存在,症状往往会持续而非消退。长期存在的麻木感可能需要更长时间才能改善,且感觉可能无法完全恢复。有些人会注意到症状时好时坏,在夜间或进行某些活动后加重。如果症状缓解六个月或更长时间后在同一部位再次出现,这通常意味着形成了新的压迫点,通常位于之前神经治疗部位的附近。
当治疗针对正确的部位时,预后通常良好。对于肩部手术后出现的神经压迫,非手术治疗很少能使其缓解,但通过手术松解神经可使近90%的症状得到解决。对于被骨骼或瘢痕组织挤压的神经,松解神经可使其自行恢复,手部小肌肉的力量得以恢复。
恢复很少是瞬间完成的。受压数月或数年的神经需要时间来愈合,感觉会在数周至数月内缓慢恢复。有些人能恢复完全的感觉。其他人则会残留一块麻木区域或感觉异常敏感的皮肤。如果神经严重受损,或者已经进行了多次手术试图解决同一问题,进一步手术缓解症状的可能性较小,您的医生会与您讨论现实可行的选择。
实际情况是:轻微症状通常可通过简单措施缓解,持续的压迫通常会导致症状持续,而恰当选择的治疗能为大多数人带来有意义的缓解。它无法保证每只手都能恢复完美的感觉。您的医生会对您进行检查,检查您的颈部,并使用神经电生理检查或超声扫描来确定导致问题的部位,然后再提出建议。
何时就医
如果麻木或刺痛感反复出现,或者休息、佩戴支具等简单措施数周后仍未缓解,请咨询您的全科医生。如果您的握力减弱、手指感觉笨拙,或症状已影响睡眠或工作,请要求专科医生评估。神经电生理检查或超声检查等检测手段可在讨论手术前确认哪根神经受压。如果受伤后突然出现麻木或无力,或手部变白、发冷或发紫,请立即前往急诊科。这些迹象表明神经或血液供应可能出现问题,需要当日评估。

- Factors that interfere with the examination of nerves in the hand include other injuries that may be life-threatening or limb-threatening, patient intoxication, anxiety, lack of cooperation, and extensive injury to the hand [15].
- If conditions are not satisfactory for a thorough examination during the initial evaluation of a hand injury, the hand should be reexamined within a reasonable period to determine the extent of nerve and other injuries sustained [15].
- An injury to digital nerves is frequently overlooked during the initial or preliminary examination of hand injuries [15].
- If a flexor tendon function deficit is present after a finger laceration, at least one digital nerve probably has been injured as well [15].
- A high index of suspicion is necessary in the evaluation of patients with hand injuries [15].
- Four areas of consideration are important when evaluating a patient with an injury to a nerve in the hand: type of injury, sensibility evaluation, motor function, and sudomotor function (sweating) [15].
- The Seddon classification of nerve injury includes neurapraxia, axonotmesis, and neurotmesis [15].
- The Sunderland classification of nerve injury includes degrees I through VI, with degree VI being a combination of any of degrees I–V [15].
- Magnetic resonance neurography (MRA) is reported to be able to provide details regarding nerve anatomic relationships, fascicular pattern, intraneural swelling, and evaluation of downstream muscle injury [15].
- Customary methods used to evaluate damaged sensory nerves include the use of a sharp pin to assess pain, a cotton-tipped applicator or finger eraser to assess light touch, and the tips of a paper clip or commercially prepared tool to assess two-point discrimination [15].
- Normal two-point discrimination usually is 6 mm or less [15].
- A patient with a transected nerve would not feel light touch, would not appreciate the pin as a sharp stimulus, and would be unable to discriminate between one and two points [15].
- Patients with closed injuries or partial injuries to nerves may show spotty appreciation of light touch and pain and have markedly widened two-point discrimination [15].
Background & Causes
Pathophysiology and Histopathology
- Chronic nerve compression histopathology begins with breakdown of the blood-nerve barrier and progresses to axonal degeneration with continued compression [16].
- Patient signs, symptoms, and sensory testing parallel the histopathologic changes occurring in the nerve during chronic compression [16].
- Abnormal postures or positions can compress nerves or place them on tension, leading to chronic nerve compression [16].
- Abnormal postures can place muscles in shortened positions, leading to secondary effects [16].
- Muscles in elongated or shortened positions become weakened and underused, causing other muscles to compensate and establish a pattern of muscle imbalance [16].
Anatomical and Structural Factors
- Bifid median nerve entrapment by forearm musculature is a potential cause of median nerve compression symptoms that surgeons should consider during assessment [10].
- The unique asymmetric neurologic innervation to the pectoralis minor predisposes the human shoulder to neurologic and musculoskeletal imbalance, producing the Human Disharmony Loop syndrome [29].
- The contribution of the anconeus epitrochlearis muscle to ulnar nerve compression neuropathy or protection of the ulnar nerve could not be discerned for the standard population [30].
Systemic and Iatrogenic Causes
- A careful medical history suggests the correct diagnosis in approximately 90% of patients with hand problems [25].
- Systemic diseases such as rheumatoid arthritis, diabetes, other endocrine disorders, renal disease, or vascular disease should be included in the medical history when evaluating hand disorders [25].
- Recent pregnancies should be questioned in women of childbearing age when evaluating hand disorders [25].
Diagnostic Considerations
- Diagnosis of mild-to-moderate median neuropathy at the carpal tunnel based on signs and symptoms is discordant from diagnosis based on electrodiagnostic studies and ultrasound [3].
- If double crush syndrome is suspected but symptoms are mild, they may respond to conservative treatment, while invasive treatments should be initiated preferentially at sites with greater clinical suspicion [13].
Symptoms & Presentation
- Clinical signs and symptoms suggest a prevalence of mild-to-moderate carpal tunnel syndrome of 73% [12].
- Electrodiagnostic studies and ultrasound indicate a prevalence of mild-to-moderate carpal tunnel syndrome of 51% [12].
- There is a severe discordance between the estimated prevalence of mild-to-moderate carpal tunnel syndrome based on clinical signs and symptoms versus electrodiagnostic studies and ultrasound [12].
- When signs and symptoms suggest mild-to-moderate median neuropathy, additional testing such as electrodiagnostic studies or ultrasound may increase the probability of actual median neuropathy that can benefit from surgery [3].
- Upper-extremity neuropathy can develop following nonupper extremity surgeries, particularly anterior cervical discectomy and fusion [4].
- As the severity of ulnar neuropathy at the elbow increases, the cross-sectional area of the ulnar nerve correspondingly increases at the elbow [8].
- Surgical decompression for neuropathy following shoulder surgery led to nearly 90% symptom resolution [6].
- In neuropathy rehabilitation, the assessment of position and tactile sensations should not be ignored in determining participation in manual skills [5].
- If double crush syndrome is suspected but symptoms are mild, they may respond to conservative treatment [13].
- Invasive treatments for double crush syndrome should be initiated preferentially at sites with greater clinical suspicion [13].
- Surgeons should bear bifid median nerve anomalies in mind when assessing patients with symptoms of median nerve compression [10].
Management
Diagnostic and Preoperative Assessment
- When signs and symptoms suggest mild-to-moderate median neuropathy and surgery is being considered, patients and clinicians might consider additional testing, such as electrodiagnostic studies (EDS) or ultrasound (US), to increase the probability of actual median neuropathy that can benefit from surgery [3].
- A high index of suspicion is necessary in the evaluation of patients with hand injuries, as digital nerve injuries are frequently overlooked [15].
- If a nerve is transected, a patient would not feel light touch, would not appreciate the pin as a sharp stimulus, and would be unable to discriminate between one and two points [15].
- The use of a pain evaluation questionnaire that includes a body diagram, a subjective questionnaire, and visual analog scales is useful in the evaluation of patients with nerve compression and/or diffuse symptoms [16].
- The carpal tunnel syndrome questionnaire assesses symptom severity (11 items) and functional status (8 items), with higher scores indicating decreased functional status [16].
- The Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire uses a standardized 30 items to allow for comparison of upper extremity conditions, with higher scores indicating higher levels of disability [16].
- The Michigan Hand Outcomes Questionnaire (MHQ) is a 67-item questionnaire that addresses specific domains of overall hand function, physical function, cosmesis, and satisfaction [16].
- The Patient-Specific Functional Scale (PSFS) assesses items identified by patients, where each patient identifies three activities or tasks that they find difficult or impossible to perform [16].
- The physical examination of suspected complex regional pain syndrome (CRPS) patients should include a neurologic assessment and evaluation of the cervical and thoracic spine [20].
- The presence of cervical disease may exacerbate CRPS, representing a form of "double-crush syndrome" [20].
- Preexisting or acquired thoracic outlet or distant compression neuropathies can represent a "triple or more" crush syndrome [20].
- There are no objective laboratory tests to aid in the diagnosis of CRPS [20].
- Paresthesias are present in up to 95% of patients with thoracic outlet syndrome (TOS) and are the most common initial complaint [21].
- An association between distal nerve compression and TOS has been attributed to a form of double-crush syndrome [21].
- Carpal tunnel syndrome is described in 21% to 45% of patients with TOS [21].
- Cubital tunnel syndrome is described in up to 10% of patients with TOS [21].
- If there is a diagnosis of TOS and a peripheral compression, and electrical studies are positive with very positive clinical findings for a distinct compression that respond appropriately to a discrete block, a separate release of the involved nerve may be performed [21].
- The authors emphasize the need for clear definitions of recurrence versus persistent compression neuropathy, agreements on supplementary diagnostics, and standardized outcome measurements to enable comparing results from different techniques and clinics [2].
- Surgeons are encouraged to bear anatomical anomalies such as bifid median nerves in mind when assessing patients with symptoms of median nerve compression [10].
Non-Operative Management
- Conservative treatment of neuroma pain should consist of medical management, including pain-modulating medications, behavior modification, therapy, and modalities such as protective garments, desensitization, massage, nerve gliding, and TENS [24].
- Local corticosteroid injections have been described for neuroma pain, though atrophy of local adipose tissue can exacerbate neuroma pain [24].
- Sensory interventions for upper limb conditions are inexpensive, noninvasive, and easy to perform, allowing them to be easily implemented into conventional therapy practice in any setting [28].
- Tricyclic antidepressants, neurotropics, or low doses of benzodiazepines may help patients with TOS sleep [21].
- Narcotics should rarely be prescribed preoperatively for TOS [21].
- If a vascular malformation is asymptomatic, it usually can be left alone [22].
- Some patients with vascular malformations are effectively treated with a fitted compression glove if the lesion tends to swell when dependent or with activity [22].
- Early management of CRPS will diminish the development of contractures, and manipulation under sympathetic blockade may prevent such contractures [19].
- Surgery on contracted joints in CRPS should not be performed until maximal nonoperative improvement has been achieved, generally requiring a waiting period of a minimum of 3 to 6 months after successful elimination of active dystrophic pain [19].
Operative Management
- Decompressing the deep motor branch of the ulnar nerve allowed for spontaneous nerve recovery and reinnervation of ulnar nerve innervated intrinsic muscles in a case of posttraumatic compressive neuropathy caused by heterotopic ossification [14].
- Anterior interosseous nerve transfer, along with cubital and ulnar tunnel release, results in sustained clinical and electrophysiological improvements in patients with severe chronic ulnar nerve compression [18].
- More than 50% of patients who did not undergo carpal tunnel release at the initial surgery for perilunate injuries required a release within the follow-up period [17].
- The best treatment for a symptomatic neuroma is prevention, which involves repairing even nonessential sensory nerves whenever possible [24].
- For established neuromas, the best strategy is to excise the neuroma and give the axons an innervation target to avoid neuroma regrowth and restore central nervous system connectivity [24].
- For a small-diameter neuroma-in-continuity, the neuroma may be excised and the nerve ends mobilized and primarily repaired [24].
- For small gaps in neuroma repair, the freshened proximal stump can be repaired via graft, conduit, or autologous nerve allograft (ANA) to the distal nerve stump [24].
- If the distal nerve is unavailable for neuroma repair, the freshened nerve end can be sewn in a reverse end-to-side (supercharging) fashion to a nearby nerve trunk [24].
- Neuroma resection was reported as the most consistently effective treatment for neuroma pain in a 25-year retrospective review [24].
- When a neuroma is not repairable and not associated with neuropathic pain, simple surgical excision and proximal transposition to a less vulnerable location are often effective [24].
- More intensive surgical methods for neuromas include open exposure and formal repositioning of the nerve stump into a deeper anatomic location such as within a muscle belly or within a medullary canal [24].
- Targeted muscle reinnervation involves identifying and dividing a motor branch of a neighboring functional muscle and performing a nerve transfer of the prepared nerve stump to the motor branch near its entry point into the muscle [24].
- Results for targeted muscle reinnervation are better if performed as part of the initial amputation procedure or soon after neuropathic pain begins [24].
- The radial sensory nerve is released at its point of compression between the tendons of the extensor carpi radialis longus and brachioradialis [23].
- A full tenotomy of the brachioradialis tendon is performed and a portion of the tendon is resected to completely decompress the radial sensory nerve [23].
- Neurolysis is not performed during radial sensory nerve decompression [23].
- A piece of bioresorbable adhesion barrier is placed over the nerve to decrease scarring after radial sensory nerve decompression [23].
- Indications for median nerve neurolysis in CRPS include quiescent or stable sympathetically maintained CRPS with mechanical pain and previous neurolysis with scar and decreased nerve mobility [19].
- Preoperative evaluation for median nerve neurolysis in CRPS includes demonstrating painful nerve gliding and evaluating peripheral nerve conduction velocities [19].
- Autogenous saphenous vein or allograft can be wrapped directly around the median nerve with an opening to allow the palmar cutaneous branch to exit [19].
- The vein graft should be sutured proximally and distally with a 5-0 or 6-0 nonreactive suture [19].
- Chromic suture should be avoided because chemicals released from the suture can create a nociceptive neural focus [19].
- An injured palmar cutaneous branch of the median nerve can be resected and moved to an unscarred area or repaired by using an end-to-end interposition antebrachial cutaneous nerve [19].
- Postoperatively, the limb is protected from pain and dystrophic flare-up by the use of continuous autonomic blockade [19].
- Motion of the affected extremity is initiated in a controlled active therapy program or by using continuous passive motion over the 3- to 5-day period of hospitalization [19].
- Surgical correction of secondary joint deformities from arthrofibrosis may be necessary after CRPS, with indications including joint pain without diffuse dystrophic symptoms and arthrofibrosis that interferes with function [19].
- Release of the metacarpophalangeal (MCP) or proximal interphalangeal (PIP) joints (or both) can be performed when nonoperative improvement has plateaued and the deformity warrants intervention [19].
- If necessary, all four MCP joints and all four PIP joints can be released in a single operation for CRPS-related contractures [19].
- Restoration of full flexion or extension is an unreasonable goal or expectation for surgery on contracted joints in CRPS [19].
- The range of motion achieved during surgery for CRPS contractures is rarely maintained after surgery as some loss is expected [19].
- Surgical management of vascular malformations aims to completely extirpate the lesion, preserving tendons, bone, nerve, and uninvolved muscle [22].
- Vascular supply is reconstituted as needed with microvascular repairs and vein grafting for vascular malformations [22].
- An aggressive surgical approach in symptomatic vascular lesions in all but the worst high-flow lesions leads to acceptable outcomes with low complication rates [22].
- Venous malformations are often seen on or around nerves, and great care should be taken to limit damage to any significant nerve in the hand [22].
- Surgical excision of venous malformations usually reduces pain and improves function for a significant period of time [22].
- For high-flow arteriovenous malformations, a surgeon should plan to excise the involved abnormal arteries and reconstruct whatever is necessary with vein grafts [22].
- The other, uninvolved artery often needs ligation to decrease the large amount of inflow characteristic of high-flow arteriovenous malformations [22].
- Ischemic digits associated with high-flow arteriovenous malformations are probably best amputated [22].
Key Considerations
- Clinical signs and symptoms for mild-to-moderate median neuropathy at the carpal tunnel are discordant from diagnoses based on electrodiagnostic studies and ultrasound [3].
- The estimated prevalence of mild-to-moderate carpal tunnel syndrome based on clinical signs and symptoms is 73%, compared to 51% based on electrodiagnostic studies and ultrasound [12].
- Surgical decompression following shoulder surgery led to nearly 90% symptom resolution for neuropathy [6].
- Decompressing the deep motor branch of the ulnar nerve caused by heterotopic ossification allowed for spontaneous nerve recovery and reinnervation of ulnar nerve innervated intrinsic muscles [14].
- Hand abduction tracings are a quantitative outcome measure to follow recovery over time for intrinsic hand function in patients with severe ulnar neuropathy following surgical intervention [11].
- Surgeons should consider bifid median nerve anomalies when assessing patients with symptoms of median nerve compression [10].
- Clear definitions of recurrence versus persistent compression neuropathy are needed for upper extremity revision nerve compression surgery [2].
- Agreements on supplementary diagnostics and standardized outcome measurements are needed to enable comparing results from different techniques and clinics in upper extremity revision nerve compression surgery [2].
