Psot - inflammation of the iliopsoas muscles. Most frequently occurs a second time due to a shift of the inflammatory process from the surrounding tissue (see Parametric) bodies of the kidneys, pancreas, retroperitoneal located vermiform process or spine. Infection can also penetrate lymphogenous and hematogenous route from neighbouring or distant organs and purulent foci. The cause of primary Paita can be a trauma (injury, wound) with education in thicker muscle hematomas, giving reactive inflammation. Psot is serous and purulent. When the last melting muscles or education in it abscess (see). Purulent clusters can give leakages (see) the pelvis, under the groin ligament in inner thighs.
For purulent Paita characterized by pain in the depth of the lumbar region with dedication during the muscles down to the appropriate thigh, chills, fever, leucocytosis with a shift leukocyte left, inflammatory contracture hips on the affected side - flexing it in the hip joint with turning outwards (psoas-symptom)that appear early and gradually progressing. The attempt to straighten the leg accompanied with sharp pain. When serous Paice moderate pain, low-grade temperature. Treatment of Paita in the initial period of conservative - cold on the lumbar region, rest, antibiotics. In the presence of ulcer-opening and draining its cavity.

Pait (psoitis; from the Greek. psoa - psoas muscle) - inflammation of the iliopsoas muscles.
Infection is more distributed lymphogenous by, aided by a rich network of lymph vessels and lymph nodes on the front surface of the muscle and in its column, which is the header of the lymph, which is flowing from the lower legs and pelvic organs. In introducing the hearth in the legs or pelvis infection with lymph reaches the iliopsoas muscle, causing its inflammation, often exudative (sero) and parenchymatous less purulent.
Hematogenous route of infection is usually observed in osteomielite bones, obstetric complications, thrombophlebitis, in some cases, when osteomyelitis lower thoracic or lumbar vertebrae, sacrum. In advanced cases of suppurative appendicitis when retrocasino the location of the process of the emergence of Paita allows you to make a correct diagnosis. Occasionally psot occurs on the basis of hematoma, which developed in the thick muscles after a failed sharp jump in hemophilia, etc.,
When Paice, as a rule, in the inflammatory process involves an enveloping lumbar muscle abundant loose cellulose. The infection penetrates into the thickness of lumbar muscles, causes excessive wetting her effusion, often with the formation of multiple small pustules. In some cases, when high virulence of infection in the thick muscles formed a single hearth - the so-called psoas-abscess (synonym of ileopsoas-abscess) is the most severe
form of Paita. Such abscesses may reach significant values down to melting all the muscles, but thanks predlagay dense fascia they rarely break into the abdominal cavity, often allowing leakages down the pelvis, under pobertova ligament on the inner thighs and other
Clinical presentation and course. Serous form of Paita may occur without symptoms, there is only a small tenderness in the course of lumbar muscles, minor bringing hip and rotation outwards. Much heavier flows purulent psot, especially with the development of psoas-abscess. You experience a high fever with morning remission, chills, then high leukocytosis, constant dull pain in face pit, a little later - pain with pressure on the lumbar area of the triangle. Against this background, extremely characteristic significant contracture hip - bring it to the stomach with rotation outwards (psoas-symptom).
Any attempt to straighten the leg accompanied by a sharp pain along the muscles. Very typical early (in the first days of the disease), the emergence of the above symptoms. Objectively observed early appearance plotnostei swelling in face pit respectively the affected side, later receiving spherical or spindle-shaped form. At the same time a severe pain occurs when pressed on the area of small spit. Later revealed swelling in the same area. Here in the future with the development of streaks appear fluctuation.
Very hard place psoty when the spread of infection to the retroperitoneal fat - picture develops extensive retroperitoneal phlegmon. Possible arrozivnym bleeding from the iliac vessels.
To differentiate psot should MaxicoM (see), parametrical (see), osteomyelitis of Ilium, the transverse processes and bodies of the lumbar and lower thoracic vertebrae, with wandering abscess tuberculosis of the spine (see Matecznik), with severe destructive appendicitis (see). Especially difficult diagnosed in advanced cases, when the main symptoms proceeds from fully developed satekov.
Antibiotic treatment can be successful (abortive)if it started in the beginning of the disease. In introducing the form of Paita the only method of treatment is surgery. The cut in 10-12 cm is conducted on two fingers above the front of the upper spine of the Ilium parallel to the summit and the outer half of papatowai ligaments. Dissect the aponeurosis of the external oblique muscle, stupidly sever fiber internal oblique transverse muscles without opening the peritoneum. At this point, from the depth of the wound under pressure starts to pus with chunks of dead muscle tissue. After finger survey cavity produce the packing. If there satekov in lumbar triangle on the inner thigh, respectively, small spit in the femoral triangle necessary to reveal them.
