Aims

Our objective was to conduct a systematic review and meta-analysis, to establish whether differences arise in clinical outcomes between autologous and synthetic bone grafts in the operative management of tibial plateau fractures.

Purpose. Tibia plateau fractures are severe knee injuries which have a great impact on the patients' lives, but in what extend is not clear yet in the literature. The purpose of this study was to investigate the gait alternations after treatment of patients who had severe tibia plateau fractures which were treated with circular ilizarov frame. Materials & Methods. We have evaluated the gait pattern of patients who were treated with circular Ilizarov frame after severe tibia plateau fractures (Schatzker IV-VI) in our department. The gait was tested by using a force plate in a walking platform. Ground Reaction Forces (GRF) data were collected during level walking at self-selected speeds. The patients performed two walking tasks for each limb and the collected data were averaged for each limb. Demographic, clinical, radiological and quality of life questionnaire (SF-12) data were also collected. Results. We have analysed the gait through the GRF of fifteen patients (aged 50.8 ±17.3 years), who had undergone treatment with circular Ilizarov frame following severe tibia plateau fractures (Schatzker IV-VI). Nine were male and six were female. The tests were performed at an average of 13.2 months after the initial treatment. SF-12 Mental scores have returned to normal (mean 54.6 ±12.3) but physical scores remained impaired (mean 40.6 ±10.8). A one-way repeated measures ANOVA was conducted to compare the GRFs and gait timing data of the affected limb with the normal one. Single limb support interval was significantly reduced to the affected limb (p=0.001) and terminal stance phase was prolonged for the normal limb (p=0.035). During this phase of the gait circle the knee is on its maximum flexion and the quadriceps contracts to bring the femur above the tibia. It seems that these patients during the gait circle reduce the flexion of their affected knee to make their single stance shorter. To the normal limb the patients manage to reduce more the GRFs during the mid-stance phase (F2 force), this difference do not reach significance, but illuminates the tendency of reduced knee flexion in that phase. The rest of the GRF and gait timing data did not had significant differences. Conclusions. One year after severe tibia plateau fracture treated with circular ilizarov frame the patients manage to return to almost normal gait pattern. Reduce single limb stance and terminal stance phase to the affected knee can be explained by the tendency of not flexing their deficient knee as much during that gait phase

Aims

It is imperative to understand the risks of operating on urgent cases during the COVID-19 (SARS-Cov-2 virus) pandemic for clinical decision-making and medical resource planning. The primary aim was to determine the mortality risk and associated variables when operating on urgent cases during the COVID-19 pandemic. The secondary objective was to assess differences in the outcome of patients treated between sites treating COVID-19 and a separate surgical site.
