Clinical and radiological results from the of a self-locking intramedullary expanding nailing system (SLINS) fixion 'trade mark' for treating failures in long bone fractures

Abstract

Apresentamos um sistema de haste intramedular inflável auto blocante (Fixion ®)) para o tratamento de fratura dos ossos longos e falhas de fixação óssea. As características e as suas vantagens técnicas incluem: fixação ao longo de toda a haste, ausência de parafusos de bloqueio proximal e distal e a fresagem é opcional. O objetivo é avaliar se as fraturas (grupo A) e as falhas de fixação óssea (grupo B) se consolidam bem sem bloqueios proximais e distais. Obtivemos 98 % de consolidação óssea para o grupo A , e 82 % para o grupo B. Conforme o índice Karlstron Olerud modificado obtivemos excelentes e bons resultados em 85% dos casos no grupo A , e 75% no grupo B. Comparamos os resultados com os da literatura mundial atual. Concluímos que as fraturas e falhas de fixação óssea se consolidam bem com este método de fixação.We present a self-locking intramedullary nailing system (Fixion®) for treatment of long bones fractures and failed fixation systems. The features of this system and the advantages of the technique include: fixation along the entire length of the nail, lack of proximal and distal interlocking screws, optional reaming, reduced exposure of the surgeon X-Ray and reduced operating room time. The purpose of this study is assessement if the fractures (group A) and failed fixation systems (group B) healed well without locking screws. Was obtained 98 % of fractures healing in group A , and 82 % in group B. According to the Karlstron Olerud Modified Score we get 85 % of excellent and good results to group A and 75% to group B. We compared to the update literature. We conclude that fractures and failed fixation systems healed well by this method
