Tenosynovitis of the fingers is also known as popping finger and trigger finger. This disease is mostly seen in women, any finger can develop, but the thumb and middle finger are the most common. 1.Diagnosis 1.1 Clinical manifestations 1.1.1 Symptoms: localized pain and weakness of the affected finger, the pain is more acute in the morning, but improves with a little activity. Extension and flexion of the affected finger is limited, with popping and “trigger-like” phenomenon. In severe cases, the finger is often locked in the flexed or extended position. 1.1.2 Physical signs 1.1.2.1 Pressure pain: localized obvious pressure pain, and can be touched nodular changes. 1.1.2.2 Local subcutaneous hard nodules, the nodules can be slightly moved when the fingers are flexed and extended, and there is a sense of elasticity. 1.1.2.3 Localized swelling of different degrees. 1.2 Diagnostic criteria 1.2.1 Obvious localized pressure pain and palpable nodular changes. 1.2.2 Local subcutaneous hard nodules, which can be slightly moved when the finger is flexed and extended, with a bouncing sensation. 2.Discrimination Due to the long-term and rapid activities of the fingers or the long-term forceful activities of the fingers, such as knitting, scribbling, etc., the tendons and tendon sheaths are repeatedly rubbed, so that the tendons and tendon sheaths are damaged and edema and hyperplasia occur. The local tendon sheath gradually thickens, forming a ring-like narrowing, compressing the edematous tendon, forming a gourd-shaped enlargement, hindering the sliding of the tendon. When the enlarged tendon passes through the stenosis of the sheath, trigger-like action and popping sound are produced. When the enlarged tendon can not pass through, the finger can not be flexed and extended, and atresia occurs. 3. Treatment 3.1 Therapeutic principle: Soothe the tendon, activate blood circulation and remove blood stasis. 3.2 Manipulation: One-finger Zen pushing method, twisting method, kneading, pointing, pressing, holding, rubbing, and plucking tendon method. 3.3 Acupuncture points: local proximity is the main point. 3.4 Operation Apply the One-Finger Zen Pushing Method and Twisting Method around the metacarpophalangeal joint of the affected finger for about 3-5 minutes. Extraction and stretching of the metacarpophalangeal joint of the affected finger: the thumb and forefinger of one hand pinch the distal phalanx of the affected finger, while the other hand pinches the proximal end of the metacarpophalangeal joint of the affected finger for antagonistic extraction and stretching. Take the thumb as an example. The doctor holds the first metacarpal bone of the affected hand with the thumb and index finger of the left hand, and places the thumb on the ulnar side of the distal phalanx of the affected thumb and the index finger on the radial side of the distal metacarpal bone of the thumb. The doctor holds the distal end of the proximal section of the thumb with the palm surface of the right thumb and the middle section of the index finger flexed, and does antagonistic traction with both hands, flexing the metacarpophalangeal joints of the affected finger while traction is being performed, and at the same time, using the end of the middle finger to hold the palmar side of the distal end of the thumb metacarpal bone of the affected finger (i.e., the stenosis of the tendon sheath), and exerting force to the ulnar side to push and squeeze the stenosis of its tendon sheath, which tends to have a tearing sensation. Finally, gently shake the metacarpophalangeal joint of the affected finger. 3.5 Other therapies 3.5.1 External application of drugs: external application of blood-activating powder. 3.5.2 Drug patch: commonly used are dog skin plaster, Qizheng pain-eliminating patch, Doc’s self-heating patch, and blood-activating bone-setting patch. 3.5.3 Acupuncture and moxibustion therapy: it has good curative effect, and the effect is better with tuina. 3.5.4 Closed therapy: fast effect, easy to relapse.
