The surgical treatment of osteitis or fracture-related infections (FRI) is often associated with large bone defects. The treatment of these defects remains a major challenge in trauma surgery. Within the concept of tissue engineering, the development of various hybrid bone graft substitutes, such as calcium hydroxyapatite with added antibiotics, is continuously progressing. ⋯ Taking the clinical and experimental results into consideration, a stricter evaluation of the indications for the use of Cerament® G is necessary to achieve the best possible outcome for patients.

The 3D printing technology is a relatively new procedure with a high potential, especially in the field of shoulder surgery. The 3D printing procedures are increasingly being developed and also gaining new users. Principally, 3D printing procedures can be applied preoperatively in planning the surgical procedure, patient clarification and in teaching; however, the technology is increasing being used intraoperatively. ⋯ Other aspects that raise questions are the time of planning, the production time and the additional cost that the use of 3D printing entails. Nonetheless, 3D printing represents a meaningful enhancement of the portfolio of surgeons, which becomes highly beneficial and useful in complex situations. Furthermore, this procedure enables a certain amount of flexibility when reacting to certain circumstances.

The importance of 3D printing applications in the surgery of musculoskeletal tumors has increased in recent years. Even prior to the era of 3D printing, computer-assisted techniques, such as navigation, have proved their utility. Due to the variable appearance of bone tumors, there is a need for individual solutions. ⋯ For these three applications, different regulatory hurdles exist. Especially for the resection of pelvic tumors, 3D printing technologies seem to provide advantages due to the complicated anatomy and the proximity to relevant neurovascular structures. With the introduction of titanium printing, construction of individualized implants that fit exactly into the defect became feasible.

The use of 3D printing in orthopedic trauma is supported by clinical evidence. Existing computed tomography (CT) data are exploited for better stereotactic identification of morphological features of the fracture and enhanced surgical planning. Due to complex logistic, technical and resource constraints, deployment of 3D printing is not straightforward from the hospital management perspective. ⋯ The installation of industrial grade machines and dedicated software as well as the use of trained personnel can enhance the capacity and reliability of fracture treatment. Setting up interdisciplinary jointly used 3d printing departments with sound financial and management structures may improve sustainability. The sometimes substantial logistic and technical barriers which impede the rapid delivery of 3D printed models are discussed.

The centerpiece of a private accident insurer is the benefit promise in cases of disability, which must be determined by a doctor in due time. The insurer specifies the rates of the compensation scheme for loss or inability to function and the medical expert must then fall back on generally recognized, revised or updated assessment recommendations in order to be able to apply the given framework to the specific, individual situation of the insured person. In four steps (basics, upper and lower extremities [disability within the compensation scheme] and disability outside the compensation scheme) interdisciplinary consensus benchmarks for disability assessment are presented, which should form the basis of a uniform medical assessment of accident-related functional disorders in private accident insurance compensation.
