Tumor resection at the pelvis using three-dimensional planning and Patient-specific templates: a case series


Jentzsch, Thorsten; Vlachopoulos, Lazaros; Fürnstahl, Philipp; Müller, Daniel A; Fuchs, Bruno (2016). Tumor resection at the pelvis using three-dimensional planning and Patient-specific templates: a case series. World Journal of Surgical Oncology, 14(1):249.

Abstract

Even experiences surgeon may not accurately reach wide Tumor resection margins at all times(1).Thus, Navigation syytem have been used intraoperative guidance. This has led to a reduction in intra-lesional resection rates. Recently,patient-specific templates (PST) have been introduces. Originally designed for total knee arthroplasties, the use of PST has been expanded to many other body parts (9) including the pelvis. Theoretcally, it offers greater precision for the resection of bone Tumors than conventional methods, potentially leadingto fewer recurrences due to inadequate margins (2). A recent well- contucted study by Gouin et al. (3) reported that Location accuracy averaged 2.5 mm in 11 cases of pelvic bone tumorstrated with PST. Our case series of four patients furtherillustrates the learning curve in three-dimensional planning andintraoperative techniques in more Detail. The ultimate Goal is toimprove the precision of osteomies for more accurate Tumor margins to reduce local recurrences. Clinicians may use this Information as practical avice to improve surgical accuracy.

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.
