Treatment results were analyzed for 78 patients (2001-2008) with pyo-inflammatory complications after hip joint replacement. Implants were preserved in 7 patients. In the rest of patients implants were removed followed by sequestrnecrectomy of articular ends and neoarthrosis formation. Treatment tactics and principles of surgical intervention were described. Good and satisfactory results were achieved in 75.44% and 24.56% of cases, respectively. Presented methods enabled to achieve weight bearing ability of the extremity and contributed to the adequate rehabilitation of patients.
Treatment outcome for 60 patients (1992-2007) with consequences of gunshot fractures of extremity bones (74 segments) have been analyzed. Expediency of use of biomechanical classification and biomechanical conception of fragments fixation for creation of stable osteosynthesis in gunshot fractures has been substantiated. Dynamics of microflora changes in stable osteosynthesis has been presented. An advantage of application of Pichkhadze apparatuses of 1st and 3rd models in gunshot fractures has been noted. Treatment of gunshot fractures with regard for biomechanical conception of fragments fixation enabled to achieve excellent and good results in 93.3% of cases.
Biomechanical classification of long bone factures, biomechanical concepts of stable fixation of fragments, devices for treatment of long bone fractures as well as computer system ORTO for choice of the most optimal treatment method and individual selection of external fixation device are suggested.
Basing on the results of theoretical analysis and experimental studies, biomechanical characteristics (resistance to displacement) of clavicle fragments of various length were determined. With regard for obtained data the requirements and indications to the application of various osteosynthesis techniques (transosseous, epiosseous, intramedullar) in different types of fractures were formulated. Treatment of clavicular fractures and their sequelae in accordance with biomecha-nical conception of fragments fixation was performed in 223 patients. Long term results were evaluated in 178 patients. Excellent results were achieved in 135 (75.9%) cases, good - in 26 (14.6%), satisfactory - in 10 (5.6%) and unsatisfactory - in 7 (3.9%) of cases. The results of the study showed that at observance of all biomechanical principles of bone fragments fixation it was possible to improve the outcomes of clavicular fractures treatment and to reduce the rate of complications considerably.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
