Distal femoral replacement for selective periprosthetic fractures above a total knee arthroplasty.
The management of distal femur periprosthetic fractures in the elderly remains a challenge. The aim of this study was to evaluate the results of distal segmental femur replacement as an alternative to fixation in complex distal femoral periprosthetic fractures in elderly patients. ⋯ WOMAC scores improved from the pre-injury state with a mean of 49.62 to 72.54 post-surgery (p-value of 0.0001). The Knee Society scores, possible only following surgery, had a mean value of 72. The mean VAS pain score was 1.75 (0 = no pain to 10 = worst pain ever felt). The average range of knee flexion was from 4° to 89° (range -5° to 110°). The mean SF-36 physical functioning score was 45.64 [range 40.70-48.90; standard deviation (SD) -2.62] and the mean SF-36 mental functioning score was 52.94 (range 45.8-57.70; SD -3.38).

The definition and use of the term "polytrauma" is inconsistent and lacks validation. This article describes the historical evolution of the term and geographical differences in its meaning, examines the challenges faced in defining it adequately in the current context, and summarizes where the international consensus process is heading, in order to provide the trauma community with a validated and universally agreed upon definition of polytrauma. ⋯ A lack of consensus in the definition of "polytrauma" was apparent. According to the international consensus opinion, both anatomical and physiological parameters should be included in the definition of polytrauma. An Abbreviated Injury Scale (AIS) based anatomical definition is the most practical and feasible given the ubiquitous use of the system. Convincing preliminary data show that two body regions with AIS >2 is a good marker of polytrauma-better than other ISS cutoffs, which could also indicate monotrauma. The selection of the most accurate physiological parameters is still underway, but they will most likely be descriptors of tissue hypoxia and coagulopathy.
