Computer-Assisted Hip Resurfacing Using Individualized Drill Templates

Immobilization and catheter guidance for breast brachytherapy

“…The printed cast also contains pre-planned catheter insertion holes. The concept of patient-specific templates has been investigated in orthopedic surgery [8][9][10][11][12][13][14] and neurosurgery [15]. To our best knowledge, there has been no research into adapting this concept for a soft tissue, such as the breast.…”

“…Magics contains a variety of modeling tools for 3D model creation, optimization, parts analysis, and repair. We choose these tools because they have been used extensively in the field of patient-specific guide design [8][9][10][11]14]. To evaluate the validity of a patient-specific template on soft tissue, multiple experiments are needed to show significance, with inserting a very large number of brachytherapy catheters.…”

Patient-Specific Modelling in Orthopedics: From Image to Surgery

“…One can now find patient-specific guides for various surgical procedures such as total knee replacement (Hafez et al 2006, Lombardi et al 2008, total hip replacement (Hananouchi et al 2009), hip surface replacement , Raaijmaakers et a. 2010, Kunz et al 2010, intra-and extraarticular radius malunions (Leong et al 2010, Oka et al 2008, and distal femur osteotomy (Victor et al 2011), Fig. 6.…”

“…For each application, a guide can provide different types of guidance. It can mechanically guide surgical gestures, such as drilling or cutting , Raaijmaakers et al 2010, Kunz et al 2010, Leong et al 2010, Oka et al 2008, Victor et al 2011 or indicate anatomical landmarks for positioning standard instruments (Blanz et al 2004). It can guide the placement of a plate by providing the drilling positions and orientations of plate fixations on preoperative bone (Leong et al 2010, Victor et al 2011.…”

Computer-assisted hip resurfacing planning using Lie group shape models

“…Computer-assisted planning can replicate this process but, preferably, uses a 3D preoperative model to provide a full spatial plan and ensure that the version angle of the implant also respects the highly variable anatomy of the femoral neck. Because these anatomical and biomechanical constraints are common to all implants, they are largely replicated in computer-assisted systems; in the Methods section, we describe the method of Kunz et al [30] as an example, but very similar methods are used in other systems that have been reported.…”
