Epidemiology study, level III.

The zones for safe screw positioning are very narrow, making percutaneous screw fixation of the acetabulum a challenging procedure. The predefined angles for the most frequently positioned percutaneous screws may aid in preoperative planning, decrease operative and radiation times and help to increase safe insertion of screws.

This report describes the case of a young athlete, who presented with a painful foot and was eventually diagnosed with early-stage Mueller-Weiss syndrome (spontaneous osteonecrosis of the navicular) by MRI. As non-operative management was unsuccessful, a percutaneous decompression of the navicular was performed. The patient made a full recovery and was able to return to her previous level of sporting activity. Subsequent imaging showed complete remodelling of the bony architecture of the affected navicular.

Implementation of MTP resulted in earlier balanced transfusion. The difference between the FFP/PRBC ratios of the two types of resuscitations levelled by 24 h. The efficacy of component therapy delivery should be measured earlier than 24 h.

This study identified a large number of preventable errors for ICC insertion in trauma patients. Standardized institutional credentialing systems may be required to ensure adequate proficiency of trainees performing this procedure.
