Nonunion and large bone defects present a therapeutic challenge to the surgeon and are often associated with significant morbidity. These defects are expensive to both the health care system and society. However, several surgical procedures have been developed to maximise patient satisfaction and minimise health-care-associated and socioeconomic costs. Integrating recent evidence into the diamond concept leads to one simple conclusion that not only provides us with answers to the "open questions" but also simplifies our entire understanding of bone healing. It has been shown that a combination of neo-osteogenesis and neovascularisation will restore tissue deficits, and that the optimal approach includes a biomaterial scaffold, cell biology techniques, a growth factor and optimisation of the mechanical environment. Further prospective, controlled, randomised clinical studies will determine the effectiveness and economic benefits of treatment with mesenchymal stem cells, not in comparison to other conventional surgical approaches but in direct conjunction with them.

BackgroundWith greater technological developments in the care of musculoskeletal patients, we are entering an era of rapid change in our understanding of the pathophysiology of traumatic injury; assessment and treatment of polytrauma and related disorders; and treatment outcomes. In developed countries, it is very likely that we will have algorithms for the approach to many musculoskeletal disorders as we strive for the best approach with which to evaluate treatment success. This debate article is founded on predictions of future health care needs that are solely based on the subjective inputs and opinions of the world's leading orthopedic surgeons.Hence, it functions more as a forum-based rather than a scientific-based presentation. This exposé was designed to stimulate debate about the emerging patients' needs in the future predicted by leading orthopedic surgeons that provide some hint as to the right direction for orthopedic care and outlines the important topics in this area.DiscussionThe authors aim to provide a general overview of orthopedic care in a typical developed country setting. However, the regional diversity of the United States and every other industrialized nation should be considered as a cofactor that may vary to some extent from our vision of improved orthopedic and trauma care of the musculoskeletal patient on an interregional level.In this forum, we will define the current and future barriers in developed countries related to musculoskeletal trauma, total joint arthroplasty, patient safety and injuries related to military conflicts, all problems that will only increase as populations age, become more mobile, and deal with political crisis.SummaryIt is very likely that the future will bring a more biological approach to fracture care with less invasive surgical procedures, flexible implants, and more rapid rehabilitation methods. This international consortium challenges the trauma and implants community to develop outcome registries that are managed through health care offices and to prepare effectively for the many future challenges that lie in store for those who treat musculoskeletal conditions.

The international orthopaedic community aims to achieve the best possible outcome for patient care by constantly modifying surgical techniques and expanding the surgeon's knowledge. These efforts require proper reflection within a setting that necessitates a higher quality standard for global orthopaedic publication. Furthermore, these techniques demand that surgeons acquire information at a rapid rate while enforcing higher standards in research performance. An international consensus exists on how to perform research and what rules should be considered when publishing a scientific paper. Despite this global agreement, in today's "Cross Check Era", too many authors do not give attention to the current (2013( ) 37:1205( -1212( DOI 10.1007( /s00264-013-1897 standards of systematic research. Thus, the purpose of this paper is to describe these performance standards, the available choices for orthopaedic surgeons and the current learning curve for seasoned teams of researchers and orthopaedic surgeons with more than three decades of experience. These lead to provide an accessible overview of all important aspects of the topics that will significantly influence the research development as we arrive at an important globalisation era in orthopaedics and trauma-related research.

Ankle arthrodesis is performed for the treatment of unstable, arthritic, painful, and deformed ankle joints. A wide variety of surgical options and approaches exist to treat the difficult problem of an ankle arthrodesis. In patients with only minor ankle deformity and minor bone loss arthroscopically assisted fusion is the treatment of choice. The risk for the development of a pseudarthrosis depends on clinical factors like corticoid medication, nicotine, incorrect alignment and improper mobilization. With adequate shoes the patients can remain asymptomatic for long time. Adjacent joints may show radiological degenerative changes in the long-term follow-up; however, they do not need to be clinically symptomatic. Nowadays total ankle replacement is a valid alternative. The surgical technique is demanding. Implants of the 1st and 2nd generation did not show satisfying results. The newer 3rd generation total ankle arthroplasties show promising medium-term and long-term results.

The ICR of the pyrocarbon implant most closely matched that of the intact MCP joint. The pyrocarbon implant provides suitable stability to radio-ulnar deviation and rotational stresses as a resurfacing implant and it simulates the kinematics of the intact MCP joint. By using new materials and taking the anatomical and biomechanical requirements into consideration, the endoprosthesis of the finger joints has created an option to achieve good long-term results. The inadequate results of earlier and current prostheses are a consequence of their mechanical construction and their materials. The success of the new implants could be proven by preferably long-term, controlled studies.
