[Radiation exposure of the eye lens in orthopedics and trauma surgery : A pilot study]. / Strahlenbelastung der Augenlinse in O&U : Eine Pilotstudie.

BACKGROUND: On 27 June 2017 the Act on new regulation of the law for the protection against the harmful effects of ionizing radiation was passed. One of the main innovations in daily surgical practice in the now legally stipulated provisions is the lowering of the eye lens dose to 20 mSv/year (§§ 78, 212 Radiation Protection Act, StrlSchG). MATERIAL AND METHODS: To estimate the level of exposure of the eye lens to ionizing radiation that is to be expected in the course of surgical interventions, the dose that surgeons receive during surgery was determined. For this, the radiation exposure adjacent to the eye lens was measured using a forehead dosimeter while performing surgical interventions over a period of 8 weeks in 2 different operating rooms. RESULTS: As a result, a mean estimated eye lens radiation dose Hp (3) of 190 µSv could be determined during the 2­month study period. Thus, the estimated cumulative radiation dose in 1 year of approximately 1.2 mSv was significantly below the threshold of 20 mSv/year. CONCLUSION: By complying with the common radiation protection measures in the context of operative interventions in orthopedics and trauma surgery, the legal limit value of 20 mSv/year is generally not expected to be exceeded.

[Single-port VATS-assisted internal fixation of serial rib fractures]. / "Single-port-VATS"-assistierte Osteosynthese von Rippenserienfrakturen.

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.
