The choice of implant in an infection of the spine depends on what type of infection it is: discitis, spondylodiscitis, early infection after spinal surgery, or a late infection. The appropriate treatment strategies vary. ⋯ In implant-associated early infections, surgical sanitization is often sufficient without changing the implant. In late infections, implant exchange is necessary because of biofilm.

[Periprosthetic fractures of the acetabulum and femur : Causes-classification-treatment algorithms].
Both increasing implantation numbers of total hip replacements and demographic change with higher populations of older people, indicate that there will be an increase in periprosthetic fractures in the future. ⋯ In the classification of periprosthetic fractures of the femur, the Vancouver classification has prevailed in recent years, which in addition to a description of the localization of the fracture also considers the stability of the prosthesis and bone quality. Based on this, therapeutic algorithms have been developed that can vary from the conservative approach via osteosynthetic options to a replacement of the prosthesis. In order to allow the description of periprosthetic fractures on all joints, the Vancouver classification has been extended to the UCS classification by including the AO/OTA bone and joint coding system. In the selection of the treatment method, the consideration of individual patient factors such as activity level and secondary diagnoses is essential. Based on the established classifications, the importance of the different therapeutic methods is presented.

The introduction of biologics has led to a great improvement in the treatment options for inflammatory rheumatic diseases. Nevertheless, surgical interventions are still necessary in many patients but a change in surgical indications could be observed. The previously predominant synovectomy of inflamed rheumatic joints is now reduced to a few so-called rebellious joints with persistent inflammation. ⋯ In patients with rheumatic diseases the mechanical stability of joint replacements, revision options, potential risk of joint infections and periprosthetic fractures vary sometimes considerably from patients with degenerative osteoarthritis. Missing clinical signs of joint infection despite a life-threatening, possibly multilocular dissemination of the disease due to immunosuppressants represents a particular challenge with respect to the diagnostics and treatment. The confusion of this with a rheumatic exacerbation might lead to general septicemia with a high mortality.

The discharge letter currently represents the gold standard of the information and transfer document in the field of inpatient orthopedic and trauma patient care. In the age of digitization, the smartphone is penetrating more and more areas of life as an omnipresent internet access medium and is thus fundamentally influencing the awareness of our society. Whereas the use of applications on smartphones is already well established today, the range of medical apps is rudimentary. The potential of apps on smartphones as an innovative digital communication medium is undeniable, but the currently available medical apps in orthopedics and trauma surgery are available to a small patient clientele only. ⋯ Currently, the use of medical apps is not an adequate alternative to the discharge letter. However, it is only a matter of time before the innovative potential of applications is used as a communication tool in outpatient and inpatient care. It is, therefore, essential to start creating the legal, ethical and medical framework and to establish a relevant regulatory body.

The movement of the forearm follows a complex interplay of three main components: the proximal and distal radioulnar joint and the interosseous membrane. Injuries to one or even all components have a huge impact on the integrity of this system. The Essex-Lopresti lesion presented a high challenge in clinical diagnostics as well as therapy. ⋯ If a reconstruction of the radial head by osteosynthesis is not possible, a radial head prosthesis should be implanted in the case of longitudinal instability - avoiding overlapping and/or oversizing. The reconstruction of the interosseous membrane should be considered, as well as the assessment of the distal radioulnar joint and/or the triangular fibrocartilage complex. Various reconstruction options are available in this regard.
