ObjectiveThere have been concerns about the potential increases in operating time associated with the use of individually wrapped presterilized small orthopaedic implants compared with our traditional method of screw banks. We set out to quantify this theory.DesignProspective experimental study.SettingTheatre.ParticipantsOrthopaedic Surgical Trainees and Theatre Scrub team.Main outcome measureThe time taken to complete the operation.ResultsThe use of prepacked and sterilized implants added 2 min 56 s to the use of a bank with a full complement of normal screws that required tapping and 3 min 58 s if self-tapping screws were used (P < 0.001).ConclusionUsing individually wrapped presterilized small orthopaedic implants increases operating time.
