A methodology for the evaluation of guiding systems. Application to total hip arthroplasty
No standard methodology exists for validating computer-aided surgery; therefore system evaluation is difficult especially when no ideal clinical goal can be specified. Thus, we have developed an approach enabling the evaluation of both an intrinsic system accuracy and an error resulting from the clinical application. Such a method has been applied to the evaluation of an image-less computer-aided guidance for total hip arthroplasty. Two parallel studies of cup orientation on SawbonesTM and patients have pointed out some critical stages of the system when clinically applied. This will allow the improvement of the system clinical usability.
