Background Surgery has greatly benefited from various technologic advancements over the past decades. Surgery remains, however, mostly manual labor performed by welltrained surgeons. Little research has focused on improving osseous drilling techniques. The objective of this study was to compare the accuracy and precision of different orthopaedic drilling techniques involving the use of both index fingers. Questions/purposes (1) Does the shooting grip technique and aiming at the contralateral index finger improve accuracy and precision in drilling? (2) Is the effect of drilling technique on accuracy and precision affected by the experience level of the performer? Methods This study included 36 participants from two Dutch training hospitals who were subdivided into three groups (N = 12 per group) based on their surgical Each author certifies that neither he or she, nor any member of his or her immediate family, has funding or commercial associations (consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article.
