Intrawound navigation for custom-made acetabular component in revision total hip arthroplasty: Does it improve implant positioning?

Background: The number of hip revisions makes up over 12 % of all hip arthroplasty cases. For large acetabular defects custom-made acetabular component (CMAC) are required. Rates of malposition of CMACs are highly variable.

Standard Versus Custom-Made Acetabular Implants in Revision Total Hip Arthroplasty.

Background: Today, various options are used for the reconstruction of acetabular bone loss in revision total hip arthroplasty (RTHA). The aim of the study was to compare the outcomes of using standard acetabular implants (SAIs) and custom-made acetabular implants (CMAIs) in RTHA in cases with extensive acetabular bone loss.

Methods: This was a comparative analysis of the results of 106 operations of RTHA performed during the period from January 2013 to December 2019.

Fibrin Glue Implants Seeded with Dental Pulp and Periodontal Ligament Stem Cells for the Repair of Periodontal Bone Defects: A Preclinical Study.

A technology to create a cell-seeded fibrin-based implant matching the size and shape of bone defect is required to create an anatomical implant. The aim of the study was to develop a technology of cell-seeded fibrin gel implant creation that has the same shape and size as the bone defect at the site of implantation. Using computed tomography (CT) images, molds representing bone defects were created by 3D printing.
