OSTEAL PLASTY METHOD OF TIBIAL BONE DEFECTS

摘要

FIELD: medicine; orthopedics.;SUBSTANCE: it is used for replacement of tibial bone defects, which occur after the sustained hematogenic osteomyelitis or trauma, or after its segmentary resection in case of tumour, dysplastic process. T-shaped cuts of fibular bone are done along the internal lateral edge whose cross-sections go at the levels of 2 prospective cross-section osteotomies considering that the distance between them should be 1 sm more than tibial bone defect. Longitudinal sections are done opposite to each other, from cross-sections on the internal lateral bone edge in metadiaphyseal zones. The length of periosteum longitudinal section is similar to the length of fibular bone moving, and the length of cross-section does not exceed half of its diameter. The periosteum is peeled off with preservation of integrity of its external lateral units. The cross-section osteotomy of fibular bone is done at 2 levels, keeping integrity of the peeled off periosteums. The fibular bone fragment is moved to tibial bone defect, with the subsequent bracing by Ilizarov apparatus.;EFFECT: restoration of tibial bone anatomic integrity and shin support ability anticnemions with biomechanics preservation in the knee and talocrural joints, acceleration of osteal regenerate formation, stable fixation of limbs, reduction of treatment terms.;6 dwg, 1 ex
