TI  - Pedicle Screw Surgery in the UK and Ireland: A Questionnaire Study.

AB  - Pedicle screw (PS) malpositioning rates are high in spine surgery. This has 
      resulted in the use of computed navigational aids to reduce the rate of 
      malposition; but these are often expensive and limited in availability. A simple 
      mechanical device to aid PS insertion might overcome some of these disadvantages. 
      The purpose of this study was to determine the demand and design criteria for a 
      simple device to aid PS placement, as well as to collect opinions and experiences 
      on PS surgery in the UK and Ireland. A postal questionnaire was sent to 422 
      spinal surgeons in the UK and Ireland. 101 questionnaires were received; 67 of 
      these (16% of total sent) contained useful information. 78% of surgeons 
      experienced problems with PS placement. The need for a simple mechanical device 
      to aid PS placement was expressed by 59% of respondent surgeons. The proportion 
      of respondents that inserted PSs in the cervical spine was 14%; PSs are mainly 
      inserted in the thoracic, lumbar and sacral spine, but potential exists for a PS 
      placement aid for the cervical and thoracic spine. From the experiences of these 
      67 surgeons, there is evidence to suggest that surgeons would prefer a pedicle 
      aid that is multiple use, one-piece, hand-held, radiolucent, unilateral and uses 
      the line of sight principle in traditional open surgery. Based on the experiences 
      of 67 surgeons, there is evidence to suggest that computed navigational aids are 
      not readily used in PS surgery and that a simple mechanical device could be a 
      better option. This paper provides useful data for improving the outcomes of 
      spinal surgery.
