Due to the exposure of the hands in the daily routine, defect wounds of the hand are common. The injury severity varies and ranges from small fingertip defects to large soft tissue lesions with exposed tendons, nerves and vessels. ⋯ A considerable variety of techniques for defect coverage are available to the surgeon but the actual challenge is to select the most appropriate procedure which will result in the smallest possible residual defect. This review article presents the diagnostic approaches to soft tissue defects of the hand and current treatment options.

Review
[Interactive augmented reality systems : Aid for personalized patient education and rehabilitation].
During patient education, information exchange plays a critical role both for patient compliance during medical or rehabilitative treatment and for obtaining an informed consent for an operative procedure. ⋯ Novel technologies, such as augmented reality are a door opener for many innovations in medicine. In the future, patient-specific systems, such as the Magic Mirror will be used increasingly more in areas such as patient education and rehabilitation. In order to maximize the benefits of such systems, further evaluation studies are necessary to find out about the best use cases and to start an iterative optimization process of these systems.

Review Case Reports
[Single-port VATS-assisted internal fixation of serial rib fractures].
This article describes the operative stabilization of a flail chest due to traumatic serial rib fractures with extensive chest wall deformation and respiratory insufficiency. Initial conservative treatment including systemic and regional pain management and non-invasive positive pressure ventilation did not improve the pain or ventilation. Therefore, a single-port video-assisted thoracoscopic surgery (VATS) assisted internal fixation of the ribs was performed. The thoracoscopy enabled easy repositioning of the ribs and additionally an estimation of intrathoracic injuries.

Despite great advances in the development of hardware and software components, surgical navigation systems have only seen limited use in current clinical settings due to their reported complexity, difficulty of integration into clinical workflows and questionable advantages over traditional imaging modalities. ⋯ Our AR navigation using RGBD cameras offers a flexible and intuitive visualization of the operating field for the navigated osteosynthesis without IR tracking markers, enabling surgeons to complete operations quicker and with a lower radiation exposure to the patient and surgical staff.

Surgical simulators are being increasingly used as an attractive alternative to clinical training in addition to conventional animal models and human specimens. Typically, surgical simulation technology is designed for the purpose of teaching technical surgical skills (so-called task trainers). Simulator training in surgery is therefore in general limited to the individual training of the surgeon and disregards the participation of the rest of the surgical team. ⋯ In the current research, assessment measurements for technical and non-technical skills are developed and evaluated. The aim is to observe multidisciplinary surgical teams in the simulated operating room during minimally invasive spinal surgery and objectively assess the performance of the individual team members and the entire team. Moreover, the effectiveness of training methods and surgical techniques or success critical factors, e. g. management of crisis situations, can be captured and objectively assessed in the controlled environment.
