Due to their excellent osteoinductive, osteogenetic, and osteoconductive properties, autologous bone grafts possess biomechanical advantages over synthetic bone substitutes. Furthermore, unlike cadaveric allografts and xenografts, they carry no risk of immunogenic response or transmission of infectious diseases. However, the limited availability of autologous bone grafts requires the use of the above-mentioned bone substitutes for management of large bone defects. ⋯ We report on intramedullary reaming by the RIA technique to obtain autologous bone graft for a nonunion of the proximal femur. The contralateral femur was reamed and the bone graft was applied to the nonunion. The patient showed clinical and radiological healing of the nonunion without donor site complications.

Evaluation of a reduction is currently a static procedure. The purpose of this study was to evaluate a model for analyzing the whole dynamic component of the reduction path up to the final result: the optimal reduction. The entire reduction procedure should be able to be retrospectively analyzed, both qualitatively and quantitatively. ⋯ Using the presented model the paths in a reduction process can be achieved as data in a simple manner. These data are supplied in a second work procedure of an automated evaluation. Thus, multiple possibilities result for retrospective analysis of the data regarding the dynamic process of a reduction.

Bacterial infections with local inflammation or hematogenous spreading may occur after joint punctures and intra- or periarticular injections. The risk of severe infections increases in patients with diseases accompanied by low immunity, e.g., gout, alcoholism, rheumatoid arthritis, and diabetes mellitus. Cases of septic omarthritis after intra-articular injection with fatal outcome after delayed onset of therapy are known. ⋯ Because the clinical picture was recognized early, we were able to prevent severe progression with organ failure. Another female patient developed a postinjection bacterial acromioclavicular arthritis followed by septic inflammatory response syndrome (SIRS) and eventually multiple organ failure (MOF). With inconspicuous clinical findings in the initial shoulder examination the bacterial arthritis was detected as the cause of sepsis only after intensive investigations.
