[Peculiarities of preparing a patient with a cochlear implant for a magnetic resonance imaging]. / Osobennosti podgotovki patsienta s kokhlearnym implantatom k provedeniyu magnitno-rezonansnoi tomografii.

OBJECTIVE: To develop an algorithm of actions aimed at preparing a patient with a cochlear implant for magnetic resonance imaging (MRI). MATERIAL AND METHODS: A deaf patient after bilateral cochlear implantation (CI) came to St. Vladimir Children's City Clinical Hospital (Moscow) with symptoms of the demyelinating disease for MRI of the brain and spinal cord. Magnet were removed for MRI, then new magnets were installed. CONCLUSION: The temporary removing magnet for MRI of the brain and spinal cord allows to significantly reduce artifacts of MRI images.

[The surgeon's procedure in dystrophic bone cysts in children]. / Taktika khirurga pri distroficheskikh kistakh kostei u detei.

The authors set apart childhood dystrophic cyst as a separate nosological unit. The underlying factor of the development of a bone cyst is dysplasia of vessels filling the bone-marrow canal and a concomitant dystrophic process in the surrounding bone tissue. The nonneoplastic nature of the cysts led to the search for sparing methods of treatment, namely, the puncture method. The administration of demineralized bone shavings during therapeutic puncture (after osteoperforation of the wall, scraping off the fibrous membrane) produces good results. The clinical material consists of 46 cases. There were 8 cases of aneurysmal bone cyst, 23 with active and 15 with passive bone cysts. In 44 cases treatment by two or three punctures led to recovery in 2-4 months. In 2 patients with aneurysmal bone cysts three punctures proved ineffective and an operative intervention was undertaken. It is concluded that treatment by puncture is indicated in dystrophic bone cysts. Operation is indicated in poor outcomes of puncture treatment in patients with aneurysmal bone cysts.

[Treatment of fractures of long tubular bones in children using a compression-distraction rod device]. / Lechenie perelomov dlinnykh trubchatykh kostei u detei s pomoshch'iu kompressionno-distraktsionnykh sterzhnevykh apparatov.

The article deals with the treatment of fractures of the long tubular bones in children by means of a rod device produced by the M. I. Sitenko Kharkov Research Institute of Traumatology and Orthopedics. It analyses some experience in the use of a compression-distraction rod device in 40 children (25 with fracture of the femur, 10 with fractures of the leg bones, 5 with fracture of the humerus). The advantages of rod devices over the other methods of treatment (pin apparatus, skeletal traction, intramedullary osteosynthesis) are shown, in the management of femoral fractures in particular. The authors consider the simplicity and easiness of the design and the possibility of rapid and bloodless installation and subsequent activation of the patient to be the main advantages of the rod device. The indications for application of the rod device were as follows: fractures which were difficult for reduction, open fractures, neglected fractures with the callus forming in improper position of the fragments, the need to perform an emergency operation on the viscera in polytrauma, delayed consolidation. Examples are given of successful treatment of patients 3 to 14 years of age. The method for applying the rod device is described as well as the possibility of expanding the volume of the reduction by using a reducing unit from the Volkov-Oganesyan apparatus together with a reducing unit from the apparatus. The possible complications which may occur in application of the apparatus and the means for overcoming them are discussed.
