The excellent primary fixation of these screwed implants in reverse arthroplasty has led us to extend our indications to anatomical replacements, in order to see whether with this kind of design we are able to decrease the frequency of RLL observed with the cemented glenoids.
These new uncemented implants in anatomical shoulder replacement have been greatly criticised, accused to be responsible of loosening, dissociation, and early PE wear.
A frequent complication after total shoulder arthroplasty is postoperative tearing of the rotator cuff, which may also result in revision of the anatomical total shoulder replacement and the implantation of a reversed shoulder arthroplasty [16].
The most important questions regard the potential role of modern imaging modalities, which may (also) give a functional rather than anatomical response assessment, the replacement of unidimensional by volumetric tumour measurements, application of RECIST in non-cytotoxic drugs, the optimal number of lesions to be measured and assessment of lymph nodes.
Hence, we suggest that the central part of the tibial canal, accessed through an entry hole at the knee center by a longer intramedullary rod, can be accepted as the best anatomical reference for knee replacements.
The gold standard technique for glenoid replacement in total anatomical shoulder prosthesis is still the use of full polyethylene cemented implant like Neer concept 40 years ago [ 1].
Stelarc explores alternate anatomical architectures.
The learning from early development process in the embryo and fetus promises faster, and facile replacements with accurate anatomical complexity.
3 patients had 2 joint replacements performed in different anatomical locations as a 1-stage procedure and 1 patient had 3 such joint replacements.
For resurfacing hip arthroplasty a porous coated anatomical system was used (Articular Surface Replacement System-ASRTM, DePuy, Warsaw, IN).
