Stenosing tenosynovitis is a common tendon sheath disease that occurs in middle-aged and elderly women and handymen who use their fingers and wrists rapidly and forcefully for long periods of time. It is also known as popping finger, which is characterized by local pain, limited extension and flexion of the affected finger, a popping sound when barely straightened, pressure pain and large nodules on the palmar side of the metacarpophalangeal joint; radial stenosis tenosynovitis, which occurs in the radial stenosis, is characterized by severe local pain and weakness when clenching and abducting the fist, and large nodules of beans can be palpated in the radial stenosis, with pressure pain. The pain is obvious. Congenital stenosing tenosynovitis refers to the inability to straighten the thumb due to stenosis of the tendon sheath at birth, or the inability to straighten the thumb after birth due to end-joint flexion. Clinical manifestations 1, the onset of the disease is slow, early only for the affected finger morning stiffness, pain, slow activity will disappear. 2, with the prolongation of the disease gradually appear each finger popping with obvious pain, serious affected finger flexion dare not move, the frequency of each finger in the order of the most middle, ring finger, show, thumb next, little finger least. 3, pain is often in the proximal interphalangeal joint, may be accompanied by joint swelling, physical examination can be found in the distal transverse palmar line at the painful nodules of soybean, with flexor tendons up and down when moving, and can occur popping. 4, radial stenosis tenosynovitis, manifested in the radial side of the wrist joint pain, lifting weakness, local pressure pain, sometimes painful nodules can be found, clenched fist ulnar deviation of the wrist joint, the radial stenosis pain. Treatment 1, local braking and tendon sheath local seal has a good effect. However, it is generally recommended to close the treatment 1-2 times, if the effect is not obvious, that should be transferred to outpatient surgical treatment. 2.If non-surgical treatment is not effective, tenosynovectomy of the stenosis can be considered. 3.Pediatric congenital stenosing tenosynovitis is generally ineffective with conservative treatment and should be treated surgically. After years of clinical observation, it is found that about 40% of patients (generally early patients and patients with mild symptoms) can be effectively relieved and cured by conservative treatment, but conservative treatment should be carried out under the guidance of an experienced specialist, not blindly. There are often patients who come to the clinic with “acupuncture treatment” or “small acupuncture knife” treatment, but not only the effect is not obvious, and even some people in the process of treatment due to some unexpected factors that lead to peripheral nerve damage, resulting in greater dysfunction. Therefore, it is recommended that patients with tenosynovitis go to a regular hospital. Usually, it can be cured by medication or simple surgery.
