A simplified guide ruler from numeric table method in doing rotational osteotomy

BACKGROUND Cobeljić et al. recently reported a numeric table method to provide precise rotational osteotomy which is a well established orthopaedic procedure. The numeric table requires four pages in length that is rather inconvenient during performing an osteotomy operation. METHODS We thus develop our own method by summarizing the data of the four-page table into a small ruler, which is eas...

A guide to numeric measures

Computer programs are increasingly capable of grouping together expressions of a discourse that denote the same entity. We regard the evaluation of this capacity as the comparison between a system’s response and the one expected by the evaluators. We outline a theoretical framework for reference (§ 1) and another one for evaluation (§ 2), then analyze three existing quality measures (§ 3.2– 3.4...

Rotational Acetabular Osteotomy

Hip dysplasia is the most common cause of secondary osteoarthritis (OA). To prevent the early onset of secondary OA, Nishio's transposition osteotomy, Steel's triple osteotomy, Eppright's dial osteotomy, Wagner's spherical acetabular osteotomy, Tagawa's rotational acetabular osteotomy (RAO), and Ganz' periacetabular osteotomy (PAO) have been proposed. PAO and RAO are now commonly used in surgic...
