Background To review the current clinical evidence on advantages and risks of early weight bearing (EWB) after internal fixation for tibial plateau fracture. Methods Data source: PubMed and Google Scholar from inception of database to 20 August 2021, using PRISMA guidelines. The included studies were randomized controlled trials, prospective and retrospective observational studies, case reports. Data extraction was performed independently by 2 reviewers. Collected data were compared to verify agreement. Statistical analysis was not performed in this study. Results The literature search produced 174 papers from PubMed and 186 from Google Scholar, with a total amount of 360 papers. The two reviewers excluded 301 papers by title or duplicates. Of the 59 remaining, 33 were excluded after reading the abstract, and 17 by reading the full text. Thus, 9 papers were finally included in the review. Conclusions EWB can be considered safe and effective in selected cases after internal fixation for tibial plateau fractures. Level of evidence Therapeutic Level III.

Introduction Sciatic nerve injury is an uncommon but potentially devastating complication in hip and pelvis surgery. Intraoperative nerve monitoring (IONM) was applied since the seventies in neurosurgery and spine surgery. Nowadays, IONM has gained popularity in other surgical specialities including orthopaedic and trauma surgery. Aim of this systematic review is to resume the literature evidences about the effectiveness of intraoperative monitoring of sciatic nerve during pelvic and hip surgery. Methods Two reviewers (GC and MD) independently identified studies by a systematic search of PubMed and Google Scholar from inception of database to 10 January 2021. Inclusion criteria were: (a) English written papers, (b) use of any type of intraoperative nerve monitoring during traumatic or elective pelvic and hip surgery, (c) comparison of the outcomes between patients who underwent nerve monitoring and patient who underwent standard procedures, (d) all study types including case reports. The present review was conducted in accordance with the 2009 PRISMA statement. Results The literature search produced 224 papers from PubMed and 594 from Google Scholar, with a total amount of 818 papers. The two reviewer excluded 683 papers by title or duplicates. Of the 135 remaining, 72 were excluded after reading the abstract, and 31 by reading the full text. Thus, 32 papers were finally included in the review. Conclusions The use of IONM during hip and pelvis surgery is debated. The review results are insufficient to support the routine use of IONM in hip and pelvis surgery. The different IONM techniques have peculiar advantages and disadvantages and differences in sensitivity and specificity without clear evidence of superiority for any. Results from different studies and different interventions are often in contrast. However, there is general agreement in recognizing a role for IONM to define the critical maneuvers, positions or pathologies that could lead to sciatic nerve intraoperative damage. Level of evidence Level 2.
