INTRODUCTION Acetabular component position can be an important determinant of joint stability and bearing surface wear after THA. Nonetheless, the incidence of malpositioning is high. Patient obesity, low surgeon volume, and minimally invasive approaches are known risk factors for malposition. As the incidence of obesity continues to increase, it is important to recognise its effect on intraope...

The use of nasogastric tube is desirable for the short-term administration of calories when oral feeding is not possible. Although the insertion of nasogastric tubes has been described as being easy this is not without risks. An unusual case of malpositioning of a fine bore nasogastric tube into both main bronchi in a patient that was awake is reported. Respiratory complications of misplaced na...

The reported incidence of lumbar pedicle screw malpositioning is between 5 and 40%. Post-operative neural deficits related to screw misplacement have been reported at rates between 3 and 11%. Radiography alone is an unreliable tool for determining pedicle wall violation due to malpositioned screws, whether by intra-operative fluoroscopy, plain X-ray, imageguided surgery systems based on radiogr...

We report a rare case of a postoperative bilateral laryngeal and pharyngeal lesion of the extracranial vagal nerve following a routine general anaesthesia in prone position. It documents a possible way of a serious complication depending to the positioning of the patient in prone position. Etiological factors and measures to avoid this rare but critical complication are discussed. For the clini...
