Fratura espontânea do colo do fêmur após retirada de PFN

Abstract: Femoral neck fracture without associated trauma following consolidation of a transtrochanteric fracture is a rare event. The authors report a case of transtrochanteric fracture that was treated with PFN and which

“…Yang et al, in a similar biomechanical study using 15 cadaveric femurs, also failed to demonstrate a significant difference in the maximum energy required for proximal femoral fractures after PFN and DHS removal. 6,9 Other studies have tested femoral reinforcement with bone cement as a technique to protect osteoporotic proximal femurs from fractures after synthesis material removal. One of these studies used synthetic femurs divided into two groups, with or without bone cement reinforcement after DHS removal, and performed biomechanical tests to determine the maximum energy required for fracture.…”

“…Yang e Cols, através de um estudo biomecânico similar utilizando 15 fêmures cadavéricos, também não conseguiram demonstrar diferença significativa nos valores de energia máxima para ocorrência de fratura no fêmur proximal após retirada de implantes do tipo PFN e DHS. 6,9 Outros estudos testaram o uso do reforço femoral com cimento ósseo como técnica de proteção à fratura do fêmur proximal em ossos osteoporóticos após retirada de material de síntese. Num desses estudos, utilizando fêmures sintéticos divididos em 2 grupos, um com e outro sem reforço de cimento ósseo após retirada do implante (DHS), realizaram testes biomecânicos com intuito de testar parâmetros de energia máxima até ocorrência de fratura.…”
