Tenosynovitis

Tenosynovitis is an inflammatory disease that affects the tendon sheaths, which are structures that wrap around tendons and allow them to glide during movement. This condition can occur either in isolation or in combination with other pathologies, such as arthritis. Tenosynovitis is characterized by pain, swelling, and limited mobility in the affected area, which can significantly reduce the patient's quality of life. Most often, the disease affects the tendons of the upper and lower extremities, but can also occur in other parts of the body. Early recognition and adequate treatment of tenosynovitis are important, since non-intervention leads to chronicity of the process and the formation of cicatricial changes.

History of the disease and interesting historical facts

Tenosynovitis has been described in medical literature for centuries. The first mentions of the condition can be found in the writings of ancient physicians such as Hippocrates. Important studies were conducted in the 19th century, when it became clear that tenosynovitis could be associated with trauma, manual labor, and even diseases such as gout. In the 20th century, the scientific community's attention to tenosynovitis increased with the development of surgery and medical imaging, which allowed for a more in-depth analysis of the disease dynamics. As a result, many forms and causes of the disease became known, including idiopathic, traumatic, and infectious factors. Scientists also noted that tenosynovitis could be a prominent manifestation of systemic diseases such as rheumatoid arthritis, which opened up a new aspect in understanding the pathology and its significance for human health.

Epidemiology

Tenosynovitis can occur in people of all ages, but there are a number of factors that contribute to its development. According to epidemiological studies, the prevalence of tenosynovitis is approximately 1-5% of the general population. It is noted that the disease is more common in women, especially between the ages of 30 and 50, which may be due to hormonal imbalances and increased susceptibility to injury. In particular, work associated with constant repetitive hand movements significantly increases the risk of tenosynovitis. Statistics also show that among athletes and people engaged in active activities, the incidence of the disease can reach 20%.

Genetic predisposition to this disease

Current research suggests that genetic predisposition to tenosynovitis may play a significant role in the development of the disease. Certain mutations and polymorphisms in genes involved in inflammatory responses and collagen metabolism may contribute to the chronicity of the inflammatory process. In particular, genes belonging to the cytokine gene family, such as IL-1 and IL-6, have been associated with an increased likelihood of developing tenosynovitis in susceptible individuals. However, it should be noted that genetic predisposition is more associated with the development of tenosynovitis as a secondary reaction to systemic diseases, such as rheumatoid arthritis, than with the primary form of the disease.

Risk factors for the development of this disease

There are several factors that can contribute to the development of tenosynovitis. The main ones include:

• Frequent physical activity and repetitive movements, especially at work;
• Joint diseases such as osteoarthritis or rheumatoid arthritis;
• Age - in older patients the risk increases significantly;
• Diabetes mellitus, which can affect connective tissue metabolism;
• Certain infectious diseases, including infections caused by viruses or bacteria;
• Occupational hazards such as increased stress on the hands and wrists;
• Lack of physical activity.

Diagnosis of this disease

Tenosynovitis is diagnosed based on clinical examination, anamnestic data and additional research results. The main symptoms are as follows:

• Pain in the tendon area, increasing with movement;
• Swelling and redness of the skin in the area of the inflamed tendon;
• Limitation of mobility of the affected limb;
• Clicking or crunching sounds when moving the joint.

Laboratory tests may include a complete blood count, which may reveal signs of inflammation (increased C-reactive protein, white blood cells, etc.). Radiological tests, such as ultrasound or MRI, can help visualize inflammatory changes in the tendons and surrounding tissues.

Differential diagnosis is important to exclude other possible causes of pain syndrome, such as carpal tunnel syndrome, bursitis, tendinitis.

Treatment

Treatment for tenosynovitis involves several approaches, which may vary depending on the severity of the condition. General treatment involves:

• Rest and avoidance of movements that aggravate symptoms;
• Physiotherapy treatments such as ultrasound and electrical stimulation;
• Using ice packs to reduce swelling.

Pharmacological treatment may include nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. In more severe cases, corticosteroids may be used, either as injections or systemic medications. Surgical treatment may be required in situations where conservative treatments fail. In such cases, removal of the affected tendon or partial resection may be considered.

List of medications used to treat this disease

Medications used to treat tenosynovitis include:

• Ibuprofen;
• Naproxen;
• Diclofenac;
• Hydrocortisone;
• Dexamethasone;
• Colchicine in the presence of concomitant gout.

Disease monitoring

Monitoring of patients with tenosynovitis is based on regular assessment of symptoms and functional status. Control stages may include:

• Regular visits to the doctor to assess the effectiveness of treatment;
• Repeated laboratory tests to monitor inflammatory markers;
• Physical rehabilitation to restore full range of motion.

The prognosis with adequate treatment is usually favorable, however complications are possible, such as chronicity of the process or the development of cicatricial changes in the tendons.

Age-related features of the disease

Tenosynovitis can manifest itself in different ways depending on the age group. Children are more likely to have traumatic forms associated with physical activity and sports overloads. In older people, the disease may be more chronic in nature with the participation of systemic diseases. Older patients may have concomitant pathologies, which complicates diagnosis and treatment.
