Complex osteotomies of tibial plateau mal-unions using computer-assisted planning and patient-specific surgical guides: Preliminary report of three cases


Fürnstahl, Philipp; Vlachopoulos, Lazaros; Schweizer, Andreas; Fucentese, Sandro F; Koch, Peter P (2015). Complex osteotomies of tibial plateau mal-unions using computer-assisted planning and patient-specific surgical guides: Preliminary report of three cases. Journal of Orthopaedic Trauma, 29(8):e270-e276.

Abstract

The accurate reduction of tibial plateau malunions can be challenging without guidance. In this work, we report on a novel technique that combines 3D computer-assisted planning with patient-specific surgical guides for improving reliability and accuracy of complex intra-articular corrective osteotomies. Preoperative planning based on 3D bone models was performed to simulate fragment mobilization and reduction in three cases. Surgical implementation of the preoperative plan using patient-specific cutting and reduction guides were evaluated, benefits and limitations of the approach were identified and discussed. The preliminary results are encouraging and show that complex intra-articular corrective osteotomies can be accurately performed with this technique. For selective patients with complex mal-unions around the tibia plateau this method might be an attractive option, with the potential to facilitate the most accurate correction possible.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
