Bone graft substitutes, especially from biocompatible materials, can be used as a solution for filling up those defects. However, these cavitary bone defects differ in size and location. It would, therefore, be convenient to utilize an implant that can change its shape according to its surrounding 3D environment, meaning there is no need to customize the implant for every patient case. In the last decade, additive manufacturing (AM) techniques have been the driving force behind the fabrication of complex three-dimensional objects. The various assets of these procedures enable the production of very complex designs with appropriate material properties. These materials that are engineered to exhibit certain properties are referred to as meta-materials. Functionalizing these materials on a nano-scale, to have certain biological or mass transport properties ...

The restoration of centre of rotation (CoR) of the hips and leg length (LL) are key factors in achieving good clinical outcome. Pelvic imaging is the gold standard for planning and assessment of LL. We aimed to better understand if 3D planning is effective at equalising LL when large acetabular defects are present. Materials and methods This was a prospective case study of 25 patients. We report the analysis of pre-operative LL status and planned LL restoration measured on CT, in relation to the achieved LL measured post-operatively in functional, weight bearing position. Our primary objective was the assessment of restoration of CoR as well as the anatomical and functional LL using biplanar full-length standing low-dose radiographs; our secondary objective was to evaluate the clinical outcome. Results Pre-operative intra-pelvic discrepancy between right and left leg was a mean of 28 mm (SD 17.99,...

Three-dimensional (3D) pre-operative planning in total hip arthroplasty (THA) is being recognized... more Three-dimensional (3D) pre-operative planning in total hip arthroplasty (THA) is being recognized as a useful tool in planning elective surgery, and as crucial to define the optimal component size, position and orientation. The aim of this study was to systematically review the existing literature for the use of 3D pre-operative planning in primary THA. A systematic literature search was performed using keywords, through PubMed, Scopus and Google Scholar, to retrieve all publications documenting the use of 3D planning in primary THA. We focussed on (1) the accuracy of implant sizing, restoration of hip biomechanics and component orientation; (2) the benefits and barriers of this tool; and (3) current gaps in literature and clinical practice. Clinical studies have highlighted the accuracy of 3D pre-operative planning in predicting the optimal component size and orientation in primary THAs. Component size planning accuracy ranged between 34–100% and 41–100% for the stem and cup respec...
