The belt of the lower extremities is called the bone ring - massive and dense - which is formed by three pelvic bones that connect to the sacrum. In an adult, they, fusing into one, form a fairly strong structure. The ischium, pubic and ilium of the pelvic bone only up to sixteen to eighteen years old exist separately. Upon reaching an older age, they are tightly fused. From this moment, one adult pelvic bone begins to exist in an adult.
An acetabulum is formed at the junction, which also has the figurative name “vinegar”. It is the receptacle of the femoral head. Due to the small size of the cavity, along the edge it is supplemented by an articular lip formed from cartilaginous tissue. The pelvic bone and sacrum are connected using articular surfaces located on the sacral bone and ilium. Despite the fact that such a joint structure is mobile, movement in it is impossible. This is due to reliable fixation with the help of the ligamentous apparatus of bone structures in relation to each other. One of the iliac structures is the wing. Its edge, speaking above the waist, is a site for puncture with a needle when receiving material from the red brain.
Each pelvic bone has branches. They are interconnected and form a locking hole. Through it, important vessels, nerves, and also muscles come out of the pelvic cavity.
Right and left pubic components are connected using connective tissue. Thus, the so-called symphysis is formed, characterized by the lack of mobility. The sciatic bones in the lower part are represented by the sciatic tubercles.
The structure of the pelvis varies, depending on the gender of the person.
In women, it is wider and lower than in men. This is due to reproductive function. In addition, the iliac wings and sciatic tubercles in women are more deployed to the sides.
Chronic pelvic pain syndrome is often diagnosed in practice. It should be noted that both women and men are susceptible to the condition.
Pelvic pain is a frequently diagnosed form of chronic prostatitis. At the same time, a number of characteristic features are noted. This form of the disease is accompanied by pain in the area of the external genitalia or perineum, as well as the pelvis for more than three months.
Given the current data on the development of the syndrome, infections are especially important, including those transmitted through sexual contact (chlamydia, mycoplasmas, gonococci, trichomonads; in rare cases, fungi, herpes virus).
The causes that cause a state of pain in women include the following:
- adhesions formed as a result of inflammation of the genital organs or in the postoperative period ;
- endometriosis;
- various ailments of a chronic nature with a long course;
- uterine fibroids;
- intrauterine contraception (spiral);
- Anomalies in the development of the genital organs, accompanied by a violation of the rejection of the uterine mucosa;
- tuberculosis in the genitals;
- soreness during menstrual cycles;
These factors are gynecological in nature. However, pain syndrome can also occur against the background of pathology of the musculoskeletal system. Such pathologies include osteochondrosis (usually lumbosacral), disc herniation, arthrosis of the sacrococcygeal joint, bone tumors, metastases, damage to the pubic joint and others.
The onset and development of a painful syndrome can be triggered by pathologies of the gastrointestinal tract, nervous system (peripheral), urinary system, as well as the formation of neoplasms in the retroperitoneal space.
