Sacroiliac joint disease (SIJD) is a group of pathologies characterized by inflammation and/or degenerative changes in the sacroiliac joint. This joint, located between the sacrum and the ilium, plays a key role in the stability of the lower body and in the transfer of loads between the upper and lower body during movement. SIJ pathologies can cause pain, limited mobility, and dysfunction, which significantly reduces the quality of life of patients.
History of the disease and interesting historical facts
Sacroiliac joint diseases have been described in medical literature since the late 19th century. The first mentions of inflammatory processes in this area date back to the works of such famous doctors as Pierre Renaud and Gustav A. Ruesch. They distinguished this pathology from more general diseases of the musculoskeletal system and raised questions about the mechanisms of its occurrence. Over time, scientists began to divide pathological conditions into acute and chronic forms, and also identified a link between sacroiliac joint diseases and systemic diseases such as ankylosing spondylitis. In the 20th century, attention to the SIJ increased, which contributed to the improvement of diagnostics and treatment methods. An important step in understanding the pathogenesis of sacroiliac joint diseases was the study of the role of autoimmune processes and genetic factors. Research continued in the 21st century, opening new horizons in understanding the relationship between this pathology and other disorders.
Epidemiology
The epidemiology of sacroiliac joint disease varies by geographic region and population. According to various studies, the prevalence of SIJ ranges from 0.5% to 5% in the adult population, with 80% cases occurring in people aged 30 to 50 years. About 50% of patients with ankylosing spondylitis also have this joint affected. In addition, the incidence of the disease increases among weakened populations, such as military personnel or people engaged in physical labor. It is important to note that the disease is less common among women than men, which may be due to differences in pathogenesis and hormonal background. Studies show that sacroiliac joint diseases tend to increase in prevalence due to changes in lifestyle and physical activity of the population.
Genetic predisposition to this disease
Genetic predisposition to sacroiliac joint diseases is established based on family history and genetic studies. One of the key factors is the presence of the HLA-B27 gene, which is found in 60-90% patients with ankylosing spondylitis and related diseases. Data on the relationship between this gene and sacroiliac joint diseases indicate that its presence may increase the risk of developing inflammatory processes in this area. However, not all HLA-B27 carriers develop pathology, which indicates the presence of multigenic mechanisms and the influence of external factors. Other disease-associated genes include genes responsible for the immune response and regulation of inflammatory processes, such as IL-1, IL-6 and TNF-α. In the future, additional genes and mutations may be identified that will help more accurately predict the risk of developing SIJ diseases.
Risk factors for the development of this disease
There are several risk factors that contribute to the development of sacroiliac joint diseases, which can be divided into physical and chemical. Physical risk factors include:
- Regular heavy physical activity that places excessive stress on the joints.
- Insufficient physical activity, which contributes to the development of atrophy of the muscles that support the joint.
- Injuries to the pelvic and lower back area, including falls and sports injuries.
- Age - Higher risks are seen in middle-aged people, especially men.
Chemical risk factors include:
- Smoking, which is associated with impaired blood supply and deterioration of tissue regeneration processes.
- Alcohol abuse, which contributes to liver pathologies and metabolic processes.
Additionally, genetic predisposition and co-morbidities such as psoriatic arthritis and reactive arthritis also increase the risk of developing sacroiliac joint disease.
Diagnosis of this disease
Diagnosis of sacroiliac joint disease involves several key steps, starting with clinical evaluation and ending with specialized research methods. The main symptoms of the disease may include:
- Pain in the sacrum and hips, often radiating to the leg.
- Limited mobility in the lower back and lumbar region.
- Morning stiffness that decreases after physical activity.
Laboratory tests may include:
- A general blood test to rule out inflammatory processes.
- Determination of the level of C-reactive protein and anti-CCE (average hemoglobin level, antibodies to HLA-B27).
Radiological examinations often become a major part of the diagnosis. Radiological examinations and MRI allow visualization of changes in the sacroiliac joint, such as:
- Lesions of articular cartilage and bone.
- Signs of inflammation and swelling of soft tissues.
Other diagnostics may include ultrasound of the joint and scintigraphy. An important step is differential diagnosis, which is necessary to exclude other diseases, such as osteoarthritis, inflammatory bowel disease or infectious processes in the joint area.
Treatment
Treatment of sacroiliac joint diseases involves a wide range of approaches depending on the type and severity of the pathology. General treatment usually includes:
- Physical therapy aimed at strengthening muscles and improving joint mobility.
- Lifestyle changes with an emphasis on adequate physical activity and correct posture.
Pharmacological treatment may include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
- Corticosteroids to control acute inflammatory processes.
- Biological therapy including TNF-α inhibitors for the treatment of ankylosing spondylitis.
In cases where conservative methods are ineffective, surgical treatment may be indicated. This may include:
- Arterio- or endoprosthetics of the joint.
- Mobilization and mobilization of joints.
Additional treatments may include:
- Physiotherapy procedures such as ultrasound or magnetic therapy.
- Acupuncture for pain relief.
List of medications used to treat this disease
Medications used to treat sacroiliac joint disease include:
- Ibuprofen (NSAID) - to relieve pain and inflammation.
- Diclofenac (NSAID) - similarly has an anti-inflammatory effect.
- Methotrexate (immunosuppressant) - used for systemic diseases.
- Etanercept (TNF-α blocker) - for severe inflammation.
- Glucocorticosteroids - for controlled relief of inflammation.
Disease monitoring
Monitoring the condition of a patient with sacroiliac joint disease requires regular control steps. These steps include:
- Periodic assessment of symptoms and their dynamics.
- Laboratory tests to monitor inflammatory markers.
- Radiological examination to assess changes in the joint.
The prognosis for ankylosing spondylitis can vary: in most cases, early diagnosis and adequate treatment can result in significant symptom relief. However, complications such as chronic pain, limited mobility, and joint deformity may develop. According to research, 30-50% patients with ankylosing spondylitis experience a time lag between diagnosis and treatment, which can negatively affect the long-term prognosis.
Age-related features of the disease
Sacroiliac joint diseases have different manifestations depending on the age group. In young patients (under 30 years old), the disease can manifest itself with acute pain syndromes and quickly become chronic. Age from 30 to 50 years is often associated with progressive deformities and a combination with other forms of spondylitis. In older patients, the disease may proceed with less pronounced symptoms, but with a high risk of complications such as osteoporosis and injuries. General health and concomitant chronic diseases also play an important role in the nature of the disease and the choice of treatment.
