Paper Abstract

We present a human-computer interface that enables the operator to plan a surgical procedure on the musculoskeletal (MS) model of the patient's lower limbs, send the modified model to the bio-mechanical analysis module, and export the scenario parameters to the surgical navigation system. The interface provides the operator with tools for: importing customized MS model of the patient, cutting bones and manipulating/removal of bony fragments, repositioning muscle insertion points, muscle removal and placing implants. After planning the operator exports the modified MS model for bio-mechanical analysis of the functional outcome. If the simulation result is satisfactory the exported scenario data may be directly used during the actual surgery. The advantages of the developed interface are the possibility of installing it in various hardware configurations and coherent operation regardless of the devices used. The hardware configurations proposed to be used with the interface are: (a) a standard computer keyboard and mouse, and a 2-D display, (b) a touch screen as a single device for both input and output, or (c) a 3-D display and a haptic device for natural manipulation of 3-D objects. The interface may be utilized in two main fields. Experienced surgeons may use it to simulate their intervention plans and prepare input data for a surgical navigation system while student or novice surgeons can use it for simulating results of their hypothetical procedure. The interface has been developed in the TLEMsafe project (www.tlemsafe.eu) funded by the European Commission FP7 program.
