Trigger thumb, also known as de Quervain's tenosynovitis, is a pathological condition associated with inflammation of the tendons surrounding the thumb. This disease is characterized by pain, swelling, and limitation of function of the thumb, which significantly complicates the performance of everyday activities. Inflammation occurs in the area of the wrist where the tendons pass through the synovial membrane and can be caused by both chronic overuse and traumatic factors. The condition is often diagnosed in people engaged in repetitive work or sports, where the movements of the wrist and thumb are repeated many times.
History of the disease and interesting historical facts
The term "de Quervain's tenosynovitis" was proposed by the Swiss surgeon Friedrich de Quervain in 1936, who was the first to describe this disease as an inflammatory process affecting the first extensor tendons of the thumb. Interestingly, the disease initially did not have a clear clinical nomenclature, and its individual manifestations were known under various names. The first mentions of such a pathological condition were noted in the works of ancient Greek and Roman doctors, however, a clear understanding of the mechanism of its occurrence came with the development of anatomy and surgery in the 19th and 20th centuries.
Epidemiology
Epidemiological studies show that the incidence of de Quervain's tenosynovitis varies by age group and occupation. According to statistics, the disease is more common in women than in men, with a ratio of approximately 3:1. The highest incidence is recorded in the 30-50 age group. According to one national study, the prevalence of this condition in the population is about 1-2%, while among professional athletes and people working with computer equipment, this figure can reach 15%.
Genetic predisposition to this disease
Currently, studies on genetic predisposition to de Quervain's tenosynovitis are being conducted in different countries, but clearly established genes and mutations that directly link genetic predisposition to this disease have not yet been identified. However, some scientists suggest that disturbances in the transmission of nerve impulses and collagen metabolism may be hereditary. Genetic studies have shown that families with similar diseases may have similar traits, although specific molecules or genetic markers have not been identified.
Risk factors for the development of this disease
There are many risk factors that contribute to the development of de Quervain's tenosynovitis. The main ones include the following:
- Playing sports, especially those that require frequent and intense movements of the thumb: tennis, golf.
- Work that involves prolonged use of a computer or other tools that require repetitive wrist and finger movements.
- Chronic strain on the wrist and thumbs.
- Previous injuries to the wrist area that may have caused inflammation.
- Hormonal changes, especially in women during pregnancy and after childbirth.
Diagnosis of this disease
Diagnosis of de Quervain's tenosynovitis is based on clinical findings and may include the following steps:
- The main symptoms are pain in the wrist area, swelling, limited movement of the thumb, especially when gripping.
- Laboratory tests are generally non-specific but may include a complete blood count to rule out other conditions.
- Radiological examinations (X-ray, ultrasound, MRI) help to visualize the inflammatory process and exclude other diseases.
- Other diagnostic tests include pain testing during movement and monitoring changes in the functionality of the thumb.
- Differential diagnosis includes osteoarthritis, rheumatoid arthritis and other forms of tendinitis.
Treatment
Treatment of de Quervain's tenosynovitis can be either conservative or surgical. The main methods include:
- General treatment: rest and avoid putting strain on the wrist.
- Pharmacological treatment: non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids to reduce inflammation.
- Surgical treatment: If conservative methods are ineffective, surgery may be performed to release the compressed tendons.
- Other treatments include physical therapy, massage, and applying heat or cold to relieve symptoms.
List of medications used to treat this disease
Some of the most commonly used medications for the treatment of de Quervain's tenosynovitis include:
- Ibuprofen (Advil, Nurofen)
- Naproxen (Aleve)
- Diclofenac (Voltaren)
- Ketorolac (Toridol)
- Injectable corticosteroids (eg, prednisolone)
Disease monitoring
Monitoring a patient with de Quervain's tenosynovitis involves regular follow-up examinations to assess treatment progress and leave room for intervention if needed. Important aspects of monitoring include:
- Follow-up: Regular consultations with your doctor to assess symptoms and treatment effectiveness.
- Prognosis: With timely treatment, there is usually good restoration of thumb function.
- Complications: Lack of treatment can lead to chronic pain and limited mobility, which negatively impacts quality of life.
Age-related features of the disease
De Quervain's tenosynovitis can occur in different age groups, but the nature and severity of the disease can vary significantly. In young patients involved in active sports, the disease will most often be caused by traumatic factors, while in women of reproductive age, there is a high probability of hormonal predisposition. In older people, the disease is more often associated with degenerative changes in the joints and structural components. It is noteworthy that in children, a condition similar to tenosynovitis is extremely rare and may be associated with an incorrect diagnosis.
Questions and Answers
- What are the main symptoms of de Quervain's tenosynovitis? The main symptoms include pain and swelling in the wrist area, limited movement of the thumb, and a crunching sensation when trying to move it.
- Is surgery necessary for de Quervain's tenosynovitis? Surgery is usually only required in cases where conservative treatment does not produce results within several weeks or months.
- How is de Quervain's tenosynovitis treated? Treatment includes rest, NSAIDs, corticosteroid injections, and, if necessary, surgery.
- How long does treatment for tenosynovitis last? The length of treatment depends on the severity of the condition, but generally, with the right approach, symptoms begin to subside within 2-6 weeks.
- Can the disease return after treatment? Yes, there is a risk of relapse, especially if exercise is not adjusted or if there is no adequate recovery.
