手指不明原因烧灼痛 – Unexplained cauterization of the finger

文章导读

  在日常中很多人都有过,手指在没有任何征兆的前提下,就出现了发烧一样的灼痛感觉,当出现这样情况的时候,会让患者感觉到非常的难受,影响到患者的日常生活。在一般情况下,当出现这样的症状是属于指端的感觉神经功能障碍,进行一些活动之后或者是过几个小时之后症状就会缓解的。

(一)发病原因

腕管是腕掌部的一个骨——纤维管,拇长屈肌和4根屈指浅肌腱、4根屈指深肌腱及正中神经通过此管进入手部。腕管在手腕掌桡侧,由腕骨和腕横韧带构成。腕横韧带坚韧,近侧缘增厚,是压迫正中神经的主要因素。正中神经在腕管中位置表浅,容易受腕横韧带的压迫,造成损伤。

腕管综合征的发病与慢性损伤有关。手及腕劳动强度大时容易发病。

引起腕管综合征的原因很多,大致可分为三类:

1.局部因素

(1)引起腕管容积减小的因素:如Colles骨折、Smith骨折、舟骨骨折及月骨脱位后畸形愈合,以及肢端肥大症等。

(2)引起腕管内容物增加的因素:如脂肪瘤、纤维瘤、腱鞘囊肿、腕管内肌肉位置异常(指浅屈肌肌腹过低、蚓状肌肌腹过高)、非特异性滑膜炎、血肿。

2.全身性因素

睡后手指出现麻木或烧灼痛而致醒 (1)引起神经变性的因素:如糖尿病、酒精中毒、感染、痛风等。

(2)改变体液平衡的因素:如妊娠、口服避孕药、长期血液透析、甲状腺功能低下。

3.姿势因素 用腕过度劳动者,如计算机操作人员、扶拐杖走路的残疾人,手指及腕关节反复屈伸。Gellman等人对77例截瘫患者调查发现,其中有38例(占49%)患有腕管综合征。

但需指出的是,有一部分患腕管综合征的患者病因不清楚。

预防方法

1.手及腕劳动强度大时应注意劳动间期休息,防止腕部正中神经持续性受压。中年女性在劳动中更要注意这一点。另外,在劳动前和劳动后放松腕部,充分活动腕关节,有助于防止腕管综合征的发生。

2.注意避免劳作中洗冷水,避免寒冷刺激和过度伸屈用力。注意局部保暖。

3.对于已经患该病的病人经过治疗后如症状缓解,要注意防止复发。要避免长时间手、腕强度较大的活动

4.因外伤所致的骨折、脱位病人如有手指麻木、疼痛,要及时到医院检查,及时治疗,可获得良好疗效。


Reading guide

  in the daily life many people have, the finger without any signs on the premise of a fever like burning sensation, when such a situation, will make the patient feel very difficult, affect the patient’s daily life. In general, when such symptoms appear to be a sensory nerve dysfunction at the fingertip, the symptoms will be relieved after a few activities or after a few hours.

(1) cause of the disease

The carpal tunnel is a bone in the carpal part. The fiber tube, the flexor pollicis longus, the 4 flexor digitorum superficialis, the 4 flexor digitorum and the median nerve enter the hand through this tube. Carpal tunnel is composed of carpal bones and transverse carpal ligaments on the palmar radial side of the wrist. The transverse carpal ligament is tenacious and the thickening of the proximal border is the main factor of compression of the median nerve. The median nerve is superficial in the carpal tunnel, and is easily compressed by the transverse carpal ligament, resulting in injury.

The incidence of carpal tunnel syndrome is associated with chronic injury. Hand and wrist labor intensity is easy to attack.

There are many reasons for carpal tunnel syndrome, which can be roughly divided into three categories:

1. local factors

(1) factors causing reduced wrist carpal volume: Colles fracture, Smith fracture, scaphoid fracture, malunion after dislocation of the lunate bone, acromegaly, etc.

(2) the factors that increase the contents of the carpal canal, such as lipoma, fibroma, tendon sheath cyst, abnormal position of muscle in the carpal tunnel (the low flexor muscle of the flexor muscle, the excessively high abdominal lumbromusculus abdominal muscle), nonspecific synovitis and hematoma.

2. systemic factors

After sleeping, the numbness or burning pain of the fingers causes waking up (1) factors causing nerve degeneration: diabetes, alcoholism, infection and gout.

(2) changing the factors of body fluid balance: pregnancy, oral contraceptives, long-term hemodialysis, hypothyroidism.

3. posture factors are excessive wrist workers, such as computer operators, walking disabled with crutches, fingers and wrist joints repeatedly flexion and extension. Gellman et al. Found 77 cases of paraplegia patients, of whom 38 cases (49%) had carpal tunnel syndrome.

However, it should be noted that some patients with carpal tunnel syndrome are not well known.

Prevention method

1. we should pay attention to the interval between work and hand to prevent the continuous compression of the median nerve of wrist. Middle aged women should pay more attention to this in their work. In addition, to relax the wrist before labor and after labor, full wrist activities can help prevent the occurrence of carpal tunnel syndrome.

2. be careful not to wash cold water during labor, avoid cold stimulation and excessive stretching. Pay attention to local warmth.

3. for patients who have already suffered from the disease, attention should be paid to preventing recurrence if symptoms are relieved after treatment. We should avoid prolonged activities with larger wrist and wrist strength.

4. due to numbness and pain in the fingers of patients with fracture and dislocation caused by trauma, timely examination should be made in time, and good results can be obtained.
