Cemented femoral component design including its mechanical behavior in total hip arthroplasty (THA) has influenced the occurrence of postoperative periprosthetic femoral fracture (PPFF). The main aim of this study was to investigate the influence of the calcar collar and surface finish in the cemented femoral component on the risk of PPFF. ⋯ This study demonstrated that the calcar collar in the cemented femoral component could play an important role to reduce the incidence of PPFF. The surface finish in the cemented femoral components influenced the incidence of femoral component revision for aseptic loosening over 5-12 years. Surgeons should consider not only the geometry and the mechanical function of the femoral components based on different design philosophies, but also potential complications associated with different designs that may require revision arthroplasty.

The fixation of small intraarticular bone fragments is clinically challenging and an obvious first orthopaedic indication for an effective bone adhesive. In the present study the feasibility of bonding freshly harvested human trabecular bone with OsSticR, a novel phosphoserine modified cement, was evaluated using a bone cylinder model pull-out test and compared with a commercial fibrin tissue adhesive. ⋯ The bone adhesive successfully glued wet and fatty tissue of osteoporotic human bone cores. The mean ultimate pull-out force of 123 N at 24 hours corresponds to ∼ 300 kPa shear stress acting on the bone core. These first ex-vivo results in human bone are a promising step toward potential clinical application in osteochondral fragment fixation.

Injury is a major health problem worldwide and a leading cause of death and disability. Disability caused by traumatic injury is often severe and long-lasting. Injuries place a large burden on societies and individuals in the community, both in cost and lost quality of life. Progress in developing effective injury prevention programs in developing countries is hindered by the lack of basic epidemiological injury data regarding the prevalence of traumatic injuries. The aim of this research was to describe the epidemiological characteristics of injury in all hospitals in Georgia. ⋯ Injuries are prevalent throughout the life course and cause substantial hospitalization time. This research can help focus prevention efforts can focus on the demographic and injury causes that are most prevalent.

Australia is one of the largest surfing nations with over 10% of the population participating; yet there is a paucity of literature analysing the injuries from surfing participation, particularly injuries requiring orthopaedic care. This study retrospectively analyses surfing injuries presenting to a tertiary hospital Emergency Department over a ten-year period with aims of quantifying surfing injuries and investigating injury characteristics requiring orthopaedic input. ⋯ Over half (56.4%) of surfing injuries were orthopaedic in nature; requiring orthopaedic advice or management. Lacerations, ligament injury, fractures and dislocations were the most commonly managed injuries. This emphasises the importance of understanding the prevalence and characteristics of surfing injuries for an orthopaedic service.

This study describes the characteristics of hand trauma treated in community-based emergency centers (CBECs) in Israel. It was hypothesized that the rate of hand trauma, as well as patient and injury characteristics, would differ from a recent study of patients treated in hospital emergency departments (EDs) in Jerusalem. ⋯ A higher rate of hand trauma was found in the CBECs in comparison to the hospital ED report (35% vs. 20% of all trauma patients, respectively). Patients treated at the CBECs, in comparison to the ED, were less often male, less often young adults, and differed in terms of type of injury. In the CBECs there were more contusions, as well as fewer lacerations and open wound injuries. In contrast, dog bites in children were found to be much more prevalent than previously reported. Hospital referral indications, the use of immobilization and pain management were found to vary according to age, gender and treatment center. Due to the high rate of hand trauma in CBECs, specific protocols are needed for these patients. The use of opioids should be specifically addressed, considering recent changes in treatment protocols. Thus, the prevalence and characteristics of hand trauma may be biased in studies based on hospital records.
