The invention relates to medicine, namely to orthopedics, and can be used in the treatment of avascular necrosis of the femoral head and of Perthes disease.

Various methods of conservative treatment of aseptic necrosis of the femoral head and of Perthes disease including: standard pharmacotherapy aimed at improving microcirculation [1, 4], improving the tone of veins [4, 5], stimulation of regeneration [6].

In turn, all of the above methods have several disadvantages:

1) low efficiency of pharmacological preparations;

2) these funds only increase congestion of venous character in stage I and II disease;

3) a large percentage of disability.

Closest to the present invention is a method of infusion of the use of antiplatelet agents (pentoxifylline, perturbat) in patients with Perthes disease [2, 3]

However, this method also has several disadvantages:

1) the level of drug in the blood after intravenous injection, mainly depends on the speed of infusion and cardiac output;

2) selectively acts only on platelets without affecting other parts of hemostasis;

3) causes thrombocytopenia;

4) does not affect the muscles in the walls of blood vessels.

The objective of the proposed method is to increase the effectiveness of treatment aseptic is about necrosis of the femoral head and of Perthes disease.

The task reach due to the fact that the patient collect 300 ml of blood from a vein with subsequent separation of RBC mass and plasma obtained aricultural mass is diluted with 200 ml of 0.9% saline and returned to the patient intravenously and plasma in the amount of 100 ml are incubated in an incubator for 20 minutes at t°=37°C, followed by adding 20 mg of the drug "Vanaprastha", the resulting mixture was injected intravenously, drip in the interval of 1.5-2 hours once a day for 10 days.

The method is as follows:

1) the patient carry out blood collection from a vein in the amount of 250-300 ml;

2) vials eksponirovannoi and heparinised blood centrifuged 15 minutes at a speed of 2000 rpm, after which the plasma exposium;

3) RBC mass is diluted with 0.9% saline solution in quantity (200 ml) and returned to the patient intravenously;

4) the plasma of the patient in the amount of 100 ml in Gamache put in a thermostat and incubated exposure 20 min at 37°C for activation of the protein in the blood plasma;

5) after incubation in the blood plasma is added 20 mg of the drug "Vazaprostan";

6) the resulting mixture was injected intravenously to the patient within 1.5-2 hours, once a day for 10 days;

7) for 15 and 60 days and 90 days after treatment dopplered epicheskoe study in the medial circumflex artery and vein of the thigh.

Comparison of treatment results was performed in 24 patients aged first and second childhood. The follow-up period was 15; 60; 90 day. To assess the effectiveness of the treatment was studied data dopplerography in the control group and study group. In the course of treatment established (table 1)that the proposed method can improve the speed parameters of arterial blood flow relative to the control group. By day 15 in the medial circumflex artery, the maximum flow velocity (Vmax) decreased by 5.8%, the minimum blood flow velocity (Vmin) increased 37.7%, eographically index (RI) decreased by 7.6% when increasing the diameter of the artery in 1,28 time. In the medial circumflex Vienna increased performance: Vmax increased by 25.6%, Vmin 19.4%, RI 29.1%, while the reduction of the diameter of the vein in 1.3 times, indicating a normalization of arterial and venous blood flow in the test group relative to the control. 60 days in the study group showed more pronounced reliable change indices, characterized by a moderate strengthening of the arterial and venous blood flow in age limits: in the artery Vmax decreased by 4.9%, Vmin increased by 8.2%, RI decreased by 2.1%, the artery diameter increased with 1.18. In venous blood flow: Vmax increased by 21.7%, Vmin 12.2%, RI by 13.7%, while the reduction of the diameter of the vein to 1.27 times relative to the control group. 90 the ducks in the artery Vmax decreased by 2.4%, Vmin increased by 15.1%, RI decreased by 6.7%, the artery diameter increased to 1.11 times. Also increased the performance of venous blood flow Vmax 16.5%, Vmin 7.2%, RI 13.3%, while the reduction of the diameter of the vein 1.13 times compared to the control group (table 1).

In the control group, the recovery time of organ blood flow were long and were $ 98.4±4.7 days, while in the studied group of children the restoration of hemodynamics in GBq was already registered on the 15th day from the start of treatment (table 2).

Thus the proposed method prolongs the clinical effect of the drug by binding with proteins (albumin) of plasma and more prolonged circulation in the blood. This leads to improved blood flow, blocking venous stasis in the area of avascular necrosis and contributes to a significant acceleration of the regeneration of the femoral head, which helped to reduce the duration of treatment in 2,8 times, greatly improve the efficiency of the treatment.

Clinical example 1. Patient Andrew K., age 11, he entered TOO GKB №20 15.01.06 diagnosed with Legg-Ka is live-Perthes disease (BP) to the left, Stage III (fragmentation).

The child for 18.5 months complained of severe pains in the left hip joint (TBS)that occurred after exercise and walk. Was sent to the clinic for examination and decision of a question on operative treatment.

On physical examination, a state of moderate severity, internal organs and clinical analyses without pathology. Locally were identified by restriction of external rotation of the right hip up to 20°, the limitation of internal rotation to 10°. Data dopplerography before treatment: medial circumflex artery Vmax (59,2 cm / sec), Vmin (11.1 cm / sec), RI (0,80%), d (1.4 mm), medial circumflex Vienna Vmax (15.9 cm / sec), Vmin (11.5 cm / sec), RI (0,23%), d (2,73 mm)

The radiological examination confirmed the diagnosis of Perthes disease (BP) on the left, the stage of fragmentation (figure 1). X-ray examination found that the left hip joint (TBS) corresponded to group III clinical and radiographic changes.

15.01.06 the child had a surgical intervention (tuplesize of the femoral neck with subsequent osteoperforative neck and femoral head pin Ilizarov) on the left TBS. After surgery, the sick child, the course of in vitro pharmacotherapy. Patient collect 300 ml of blood from a vein with subsequent separation of RBC mass and plasma, the scientists aricultural mass is diluted with 200 ml of 0.9% saline and returned to the patient intravenously, and the plasma in the amount of 100 ml are incubated in an incubator for 20 minutes at t°=37°C, followed by adding 20 mg of the drug "Vanaprastha", the resulting mixture was injected intravenously, drip in the interval of 1.5-2 hours once a day for 10 days. Data dopplerography on 30.01.06, in the medial circumflex artery Vmax (55,2 cm / sec), Vmin (16,3 cm / sec), RI (0,70%), d (1,85 mm), medial circumflex veins Vmax (20.5 cm / sec), Vmin (14,4 cm / sec), RI (0,32%), d (2.1 mm). 30.01.06 on the radiograph positive dynamics of the recovery patterns of the femoral head. After the child received medical rehabilitation, performed the prescribed orthopedic mode. Through 4.8 months. after the first operation the radiological examination, he was diagnosed with stage V BP (Exodus) (figure 2).

When ray study has shown a significant improvement in clinical and radiological condition TBS compared with the preoperative period.

Thus, the use of extracorporeal infusion of vanaprastha in BP treatment was effective for the patient. During treatment was able to restore clinical and radiological condition of the affected TBS from III to I clinical-radiological group, to fully restore the anatomical parameters of the femoral head (HBR), which allowed to reduce the treatment time in 2.8 times.

The wedge is ical example 2. Patient Dima W., age 7, entered TOO GKB №20 17.10.05 diagnosed with Legg-calve-Perthes disease right, stage III (fragmentation).

The child within 27 months complained of fatigue, severe pains in the TBS that occurred after exercise and walk. Was sent CRH clinic for examination and decision of a question on conservative and surgical treatment.

On physical examination, a state of moderate severity, internal organs and clinical analyses - without a pathology. Locally - was identified on the right positive symptom Trendelenburg and limitation of external rotation of the right hip up to 20°. Data dopplerography before treatment: medial circumflex artery Vmax (59,3 cm / sec), Vmin (11.2 cm / sec), RI (0,80%), d (1,41 mm), medial circumflex veins Vmax (15.8 cm / sec), Vmin (11.6 cm / sec), RI (0,24%), d (2,71 mm).

The radiological examination confirmed the diagnosis of BP to the right, the stage of fragmentation (figure 3). The radiological examination established that the right-TBS corresponded to group III clinical and radiographic changes.

20.10.05 child day treatment (tuplesize of the femoral neck with subsequent osteoperforative neck and femoral head pin Ilizarov) and applying the standard conservative therapy with antiplatelet agents. Data dopplerography on 22.01.06, medial envelope artery the Vmax (55,7 cm / sec), Vmin (15.9 cm / sec), RI (0,73%), d (1,73 mm), medial circumflex Vienna Vmax (19.5 cm / sec), Vmin (13,9 cm / sec), RI (0,31%), d (2,49 mm).

With 22.01.06 after registration on the radiograph positive dynamics of recovery patterns GBq, the child received medical rehabilitation, performed the prescribed orthopedic mode. Through 14.2 months. after the first surgery and conservative therapy for x-ray examination, he was diagnosed with stage V BP (Exodus) (figure 4).

Chest x-ray is set to improve clinical and radiological condition TBS compared with the preoperative period. Right TBS corresponded II clinical-radiological group.

Thus, the use of surgical treatment and the standard conservative therapy was not effective in the patient. During treatment was able to improve clinical and radiological condition of the affected TBS from III to II clinical-radiological group, however, full recovery of anatomical parameters GBq corresponding to group I, could not be reached.

Compared with the prototype of the proposed method has the following advantages: resistant removing venous stasis in the proximal femur, normalization of arterial blood flow leading to improved revascularization of the affected epiphysis and a significant acceleration of regeneration of the femoral head, reducing the duration of treatment in 2.8 times.
