Trochanteric osteotomy in primary and revision total hip arthroplasty: risk factors for non-union


Wieser, Karl; Zingg, Patrick; Dora, Claudio (2012). Trochanteric osteotomy in primary and revision total hip arthroplasty: risk factors for non-union. Archives of Orthopaedic and Trauma Surgery, 132(5):711-717.

Abstract

BACKGROUND: Trochanteric osteotomies (TO) facilitate exposure and "true hip reconstruction" in complex primary and revision total hip arthroplasty (THA). However, non-union represents a clinically relevant complication. The purpose of the present study was to identify risk factors for trochanteric non-union. METHODS: All cases of THA approached by TO during the past 10 years were analyzed with respect to potential risk factors for non-union. RESULTS: In 298 cases complete data were available for analysis. Trochanteric union occurred in 80.5%, fibrous union in 5.4% and non-union 14.1%. Risk factor analysis revealed a four times higher risk for non-union in anterior trochanteric slide osteotomies compared to extended trochanteric osteotomies and a three times higher risk in cemented versus non-cemented stems. Multiple logistic regression analysis revealed patient's age and use of cement to be independent risk factors for non-union. CONCLUSIONS: Femoral cementation and increasing age negatively influence the union of trochanteric osteotomies.

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.
