Displaced acetabular fractures in the elderly present significant treatment challenges. The 'fix and replace' concept involves open reduction and internal fixation of the acetabulum, providing bony stability to accept the press-fit of an acetabular cup, with a cemented femoral stem. This allows early mobilisation and the advantages this confers. This study of 57 patients treated with fix and replace describes our technique, outcomes, and survival analysis. ⋯ While fix and replace is conceptually attractive, this medically complex patient group requires considerable support peri‑ and post-operatively. Further studies are required to provide clinicians with more information to decide on how best to provide a holistic management strategy for such injuries in this frail patient cohort.

We have proposed a novel intramedullary nail (Ni-Nail) by incorporating a sustentaculum tali screw to improve the fixation stability of minimally invasive treatment for calcaneal fractures. This study aimed to evaluate the biomechanical characters of the Ni-Nail system and compare it with traditional C-Nail system. ⋯ Our static simulation analysis showed that both Ni-Nail and C-Nail demonstrated similar biomechanical stability for calcaneal fixation. The Ni-Nail features a simple structure that is easier to operate and less traumatizing. Future studies may consider to further evaluate the clinical effectiveness by clinical trials and follow-ups.

There are several options available for conservative treatment of partial-thickness burns, however, reliable, affordable, and easily obtainable animal testing models are hard to find for the comparison of the different treatment methods. We aimed at developing a preclinical testing model and at comparing four treatment methods for superficial partial-thickness burns. ⋯ We designed and histologically confirmed a reproducible method for induction of superficial partial-thickness burns in rats for preclinical testing. In our model, the combination of zinc-hyaluronan gel with silver foam dressing was more effective than either of its components alone or than silver-sulfadiazine cream.

The number of older adults hospitalised for injury is growing rapidly. The population-adjusted incidence of isolated thoracic injuries in older adults is also growing. While some older adults are at high risk of post-traumatic complications, not all older adults will need treatment in a major trauma service (MTS). The aim of this study was to characterise older patients with isolated chest injuries, determine the rates of post-traumatic complications, including respiratory failure and pneumonia, and the factors associated with the risk of developing these complications. ⋯ Our findings suggest that rates of complications in older patients with isolated chest trauma in this study were low, and that there is a large group of patients with isolated, uncomplicated rib fractures, who may not need to be treated in a major trauma centre. Further work should be undertaken to appropriately risk stratify and manage older adults with isolated chest trauma.
