Masquelet technique is a two-stage surgical procedure used in the treatment of critical-size bone defects (CSD). Adding antibiotics to polymethylmethacrylate (PMMA) is still questionable to create higher quality induced membrane (IM). The aim of the study was to evaluate the effects of three antibiotic-supplemented cement, fusidic acid, teicoplanin, and gentamicin, on osteogenesis and IM progression applied to rat femur CSD model by comparing histopathological, biochemical, and immunohistochemical findings. ⋯ The bone cement impregnated with thermostable and safe antibiotics, gentamicin, fusidic acid, and teicoplanin can increase osteogenesis and support IM progression by increasing the expressions of TGF-β and VEGF. Anabolic effects of induced membranes used in the treatment of critical-size bone defects can be enhanced by antibiotic-supplemented PMMAs applied by altering the original technique.

Early patient assessment is relevant for surgical decision making in severely injured patients and early definitive surgery is known to be beneficial in stable patients. The aim of this systematic review is to extract parameters indicative of risk factors for adverse outcome. Moreover, we aim to improve decision making and separate patients who would benefit from early versus staged definitive surgical fixation. ⋯ In this systematic literature review, we summarize publications by focusing on different pathways that stimulate pathophysiological cascades and remote organ damage. We propose that these parameters can be used for clinical decision making within the concept of safe definitive surgery (SDS) in the treatment of severely injured patients.

Distal femoral fractures in elderly or osteoporotic patients constitute a challenging injury, especially in the settings of fracture comminution or periprosthetic fractures. A recent trend in the treatment of these difficult injuries is the double fixation with a nail and a plate, a strategy that comes with advantages including faster weight-bearing and lower risk for non-union. Although biomechanical studies have demonstrated the superiority of nail-plate constructs, there is a paucity in the literature regarding the indications and results of treatment. A review of the literature to date was carried out to identify which group of patients would benefit the most from this type of reconstruction and to evaluate the clinical outcomes.

Injuries are predicted to become a greater cause of mortality than communicable diseases in sub-Saharan Africa by 2030, signaling a public health dilemma for governments and citizens in each country. This article uses epidemiological estimates of injuries in Zambia, considers the socio-economic impact of injuries, examines current policies for prevention, and provides a rapid situation analysis to help develop an action and research agenda for injury prevention in the country. It calls for better epidemiological data, capacity building for human resources, and adoption of evidence-based targets and interventions. For Zambia to reduce its burden of injuries, funding for research and training should be integral to the future of its national health agenda.
