ABSTRACT
One of the difficulties that a surgeon faces is the need to visually precept the impact that his surgery plan will have on the patient. In the case of orthopedic surgery, this is even more important, since the analysis of implant’s placement (when necessary) is only possible in realtime (surgery). However, it is important to annotate the location/actual position of a pre-surgical implant, thereby reducing the risk inherent to any surgical intervention. Allowing the patient situation to be previously analyzed in detail and with greater time interval, the task of the orthopedic surgeon is facilitated, because the pressure of the decision making during surgery is reduced (Mabrey, Reinig, & Cannon 2010, The, Verdonschot, van Horn, van Ooijen, & Diercks 2007).
