摘要：
The invention relates to medical engineering and can be used in orthopedics for the treatment of avascular necrosis of the femoral head and other diseases associated with the destruction of the upper pole of the femoral head. Device for rotary osteotomy femoral head (1) comprises a support 1, with the attached through biaxial hinge 2, with the possibility of axial movement, bone screws 3 and 4 of the rotary tube assembly 5 (Figure 2). The rotary unit 5 comprises a coaxially mounted tube 4, a sleeve 6, nuts 7 and 8 and the threaded rod 9. In this case the tube 4 is formed with an outer threading 10 and the helical groove 11. Cutting Step helical grooves 11 over the step 10 of the male threading. The sleeve 6 (Figure 3) is formed, on the one hand, with a radially directed tenon 12 in contact with the surface of the helical groove 11, on the other - with the end opening with flats 13 in contact with the flats 14 provided on the threaded rod 9. The end of the sleeve 6 by the radially directed shi na 12 abuts against the nut 7, installed on the tube 4, and a threaded rod 9 is fixed bolts 8, one of which abuts the tube end 4 and a second opposite end of the sleeve 6. In addition to the slots 15, the threaded rod 9 installed spokes 16. The technical result is to provide smooth dosage closed and rotation of the femoral head during compression osteosynthesis of bone fragments, with the installation of bone screws at an arbitrary angle to the support. 3 yl.Полезная модель относится к медицинской технике и может быть использована в ортопедии при лечении асептического некроза головки бедренной кости и других заболеваний, связанных с деструкцией верхнего полюса головки бедра. Устройство для ротационной остеотомии головки бедра (Фиг.1) содержит опору 1, с установленными на ней посредством двухосевых шарниров 2, с возможностью осевого перемещения, костными винтами 3 и трубкой 4 ротационного узла 5 (Фиг.2). Ротационный узел 5 содержит соосно установленные трубку 4, втулку 6, гайки
