Biomechanical Effects of a Cross Connector in Sacral Fractures – A Finite Element Analysis

Abstract: Background: Spinopelvic fractures and approaches of operative stabilization have been a source of controversial discussion. Biomechanical data support the benefit of a spinopelvic stabilization and minimally invasive procedures help to reduce the dissatisfying complication rate. The role of a cross connector within spinopelvic devices remains inconclusive. We aimed to analyze the effect of a cross connector in a finite element model (FE model).Study Design: A FE model of the L1-L5 spine segment with pelvis and… Show more

“…Yet, this procedure is known to increase trauma (19). In the FEM study, exceeding the capacity of the material properties would be deemed as failure of fracture fixation (20)(21)(22). In clinical reality, it is widely assumed that-if internal fixation of a tibial plateau fracture is deemed suboptimal-the patient must be instructed to perform severely limited weight bearing and/or limited range of knee motion.…”

“…Im Fall einer beidseitigen lumbopelvinen Abstützung kann durch das Einbringen eines Querträgers die Stabilität des Konstrukts nochmals verbessert werden. Finite-Elemente-Analysen konnten zeigen, dass mit dem Querverbinder die Beweglichkeit im Frakturbereich nochmals deutlich reduziert wurde [26].…”
