title: [Neurosurgical position causes peripheral nerve injuries?]
abstract: BACKGROUND
  Positioning during neurosurgical procedures is a challenge for surgical teams even if precautions are taken, the mechanisms underlying peripheral nerve injury (elongation, compression or ischaemia) are latent and it is important to know the frequency of occurrence in our environment.
  
  
  OBJECTIVE
  To analyze the frequency of peripheral nerve injury secondary to surgical positioning.
  
  
  METHODS
  Prospective study including 163 patients scheduled for neurosurgical procedures. Four groups: supine, lateral, ventral and park bench were analyzed by neurological exploration in order to detect injury and relate with risk factors already described.
  
  
  RESULTS
  In this study 112 patients were included, two patients who were under park bench position experienced paresthesias in ulnar region of less than 24 hours' duration; statistically significant correlation with body weight greater than 85kg.
  
  
  CONCLUSIONS
  The incidence of peripheral nerve injury is low, understanding the mechanisms that may originate it helps towards prevention and early detection of complications.
