Optimal thromboprophylaxis in orthopaedic procedures is crucial in an attempt to lower the risk of venous thromboembolism, including deep vein thrombosis and pulmonary embolism. We aim to: 1) identify clinical practice guidelines (CPGs) and recommendations (CPRs) on thromboprophylaxis in adult patients undergoing orthopaedic procedures, and 2) assess the methodological quality and reporting clarity of these guidelines. ⋯ Optimal thromboprophylaxis in orthopaedic procedures is crucial. The available guidelines were found to be mostly of high methodological quality and inter-rater agreement was very good, according to our study.

Recent studies report the overall incidence of distal femur fractures as 8.7/100,000/year. This incidence is expected to rise with high energy motor vehicle collisions and elderly osteoporotic fractures in native and prosthetic knees keep increasing. These fractures are more common in males in the younger age spectrum while females predominate for elderly osteoporotic fractures. ⋯ Early results with these combination constructs have shown promise in high risk situations such as fractures with extensive metaphyseal fragmentation, osteoporosis and periprosthetic fractures. These constructs however, run the risk of being over stiff and can inhibit healing if not kept balanced. The ideal stiffness that is needed for fracture healing is not clearly known and current research in this domain has lead to the development of smart implants which are expected to evolve and may help improve clinical results in future.

Although the Head Injury Criteria (HIC) has been widely applied to assess head impact injuries, it faces two outstanding problems: 1) HIC is affected strongly by the cut-off frequency when processing acceleration signals. And these cut-off frequencies are experiential and lack unified guidelines; 2) If the head was impacted on a different part, should the corresponding HIC threshold be the same? If these problems are not resolved, it could potentially lead to a critical misinterpretation of the safety assessment. ⋯ The rational filtering class like CFC 800 and CFC 700 were given for rigid body HIC and centroid node HIC, respectively. The rigid body HIC had a significant discrepancy from the centroid node HIC. Linear relations between the rigid body HIC and centroid node HIC were found, and their slopes changed with impact directions. From these relations, we can adjust the injury thresholds reasonably if the head receives different impacts. These findings can effectively enhance the applicability of HIC.

Comparative Study
Biomechanical comparisons of plate placement for medial tibial plateau fractures (Schatzker type IV): A biomechanical study using porcine tibias.
Biomechanical studies on medial tibial plateau fractures (MTPFs) (Schatzker classification type IV) are currently few, while studies using locking plates (LPs) placed on medial proximal tibias are unavailable. Hence, we compared the biomechanical properties of plate osteosynthesis at the medial and anteromedial placements using large- and small-fragment LPs in porcine bones. ⋯ Medial LP placement for MTPFs in porcine bones resulted in significantly lower posterior step-offs after cyclic loading than anteromedial placement, and large-fragment LPs for MTPFs caused significantly lower fracture gaps in the central articular after cyclic loading than small-fragment LPs.

There remains a paucity of evidence on the early predictors of long-term Health-Related Quality of Life (HRQoL) outcomes post-burn in hospitalised adults. The overall aim of this study was to identify the factors (personal, environmental, burn injury and burn treatment factors) that may predict long-term HRQoL outcomes among adult survivors of hospitalised burn injuries at 12 months post-burn. A total of 274 participants, aged 18 years or over, admitted to a single state-wide burn centre with a burn injury were recruited. ⋯ However, for participants with poor HRQoL outcomes at 12-months post-burn, Univariable predictors included longer hospital length of stay, unemployment at the time of injury, a diagnosed pre-injury mental health condition, inadequate pre-burn social support, intentional injury, recreational drug use pre-injury and female gender. The early multivariable predictors of insufficient HRQoL outcomes were female gender, a previously diagnosed mental health condition, unemployment, inadequate social support, intentional injury, and prolonged hospital length of stay. These results suggest potential factors that could be used to screen and burns patients for psychosocial intervention and long-term follow up.
