Knott's disease (stenosing ligamentitis) is one of the most common diseases of the hand, which is the reason for visiting an orthopedist. The essence of the disease lies in the difficult extension of the fingers, which is a consequence of the pathological state of the ligamentous apparatus of the hand.

results of ultrasonography or ultrasound examination
If attempts to straighten one or more fingers of the hand do not lead to the desired result, it is necessary to consult an orthopedic surgeon for a thorough diagnosis of this pathology. During special testing, you need to unbend your finger on your own, without the help of a second hand. If the attempt is unsuccessful, and when unbending with assistance, pain in the finger occurs, accompanied by a characteristic click, Nott's disease (clicking finger) is diagnosed. In addition, with this ailment, a dense rounded formation is observed at the base of the finger.
The disease is caused by infringement of the extensor and flexor tendons of the fingers due to narrowing of the annular ligament of an inflammatory nature. With advanced stages of the disease, extension becomes impossible.
When choosing the optimal method for treating Knott's disease, it is very important to determine at what stage in the development of the pathological process the patient turned to a specialist. At the first stage of the disease, the mobility of the finger is limited and a click appears when extending, at the second, the extension is carried out with the use of certain efforts. In the third degree, the finger takes a fixed position and does not bend. The fourth stage usually develops without treatment. Secondary deformation of the joint occurs, which makes the limitation of mobility irreversible.
When choosing a conservative treatment, the doctor should make sure that the extension of the finger is difficult, but still possible. This method consists of applying special compresses to the affected area and applying physiotherapy. The course of such treatment usually lasts for several months, and if there is no effect, surgery is performed.
To prevent possible complications during surgical treatment, the patient must undergo a thorough medical examination. In most cases, the operation is performed under local anesthesia. The postoperative period usually lasts about two weeks, after which the doctor must prescribe therapeutic exercises and physiotherapy aimed at the complete restoration of the functions of the hand.
