Randomized Controlled Trial Comparative Study
Minimally invasive plate osteosynthesis has equal safety to reamed intramedullary nails in treating Gustilo-Anderson type I, II and III-A open tibial shaft fractures.
The best fixation method for open tibial fractures has long been a matter of debate, many studies have recommended the use of intramedullary nails over external fixation for treating such fractures, recent studies also showed favorable results for the use of plates in managing open tibial fractures. However, there are very few (if any) reports in the literature comparing the use of minimally invasive plate osteosynthesis to reamed intramedullary nails in the fixation of open tibial fractures. The aim of this study was to compare the safety & efficiency of minimally invasive plate osteosynthesis to reamed intramedullary nails in treating open tibial shaft fractures. ⋯ Level II, Therapeutic study.

Blood loss estimation after trauma (i.e. physical injury) and early identification of potential sources of bleeding are important for planning of investigation and management of trauma. Long bone fractures have been reported to be associated with substantial volumes of blood loss requiring blood transfusion. The aim of this study was to assess rates and amounts of blood transfusion in the setting of isolated extra capsular femur fractures and to determine variables associated with the need for transfusion within the first 48 h of admission. ⋯ Volume of blood transfused to patients with extra-capsular femoral fractures was low and usually in the post-operative period. FSF, compared to femoral extremity fractures, were not more likely to receive blood transfusion within the first 48 h of admission, and did not receive a higher volume of blood overall. In the setting of major trauma with haemorrhagic shock, alternate sources of bleeding should be sought.

It has been previously suggested that the use of regenerative promoters, which include bone marrow-derived mesenchymal stem cells (MSCs) or natural growth factors supplement such as platelet-rich concentrate (PRC) could promote cartilage regeneration. However, the notion that the concurrent use of both promoters may provide a synergistic effect that improves the repair outcome of focal cartilage injury has not been previously demonstrated. This study was thus conducted to determine whether the concomitant use of PRC could further enhance the reparative potential of MSCs encapsulated in alginate transplanted into focal cartilage injury in rabbits. ⋯ PRC enhances the reparative effects of MSC in treating focal articular cartilage injuries.

Value of PCR in sonication fluid for the diagnosis of orthopedic hardware-associated infections: Has the molecular era arrived?
Bone healing disturbance following fracture fixation represents a continuing challenge. We evaluated a novel fully automated polymerase chain reaction (PCR) assay using sonication fluid from retrieved orthopedic hardware to diagnose infection. ⋯ The performance of sonication fluid PCR for diagnosis of orthopedic hardware-associated infection was comparable to culture tests. The additional advantage of PCR was short processing time (<5 h) and fully automated procedure. With further improvement of the performance, PCR has the potential to complement conventional cultures.

Radiographic fracture classification helps with research on prognosis and treatment. AO/OTA classification into fracture type has shown to be reliable, but further classification of fractures into subgroups reduces the interobserver agreement and takes a considerable amount of practice and experience in order to master. ⋯ This study adds to a growing body of evidence that relatively simple distinctions are more reliable and that this is independent of surgeon experience.
