Литература:
Magnetic Resonance Imaging (Magneton Simphoni Siemens) was performed with postprocessing on multimode station of expert class 'Leonardo' in 32 patients with intraarticular fractures of a knee joint before treatment, directly after frame removal and in a longterm period after trauma. Visualized capacities of MRI enabled to reveal a number of significant changes of mineralized and nonmineralized components of a distal end of a femoral and proximal part of a tibial bone after trauma (trabecular edema, cysts, bone cavities, state like vascular fascicle, metallosis). Consolidated fractures are characterized by hypointensive signals on T1-weighted images and Т2-weighted images from sclerotic parts of bone marrow, planes of former fractures, posttraumatic bone cavities, enlargement of scar tissue, nonhomogenous periosteal callus that are revealed during MRI until 4 and more years after termination of a course of treatment, especially in incomplete reduction of fracture. Precise reduction considerably reduces period of reconstruction of bone structure and medullary canal at the zone of fracture (up to 1-2 years).
