Treatment of reduced femoral antetorsion by subtrochanteric rotational osteotomy


Huber, H; Haefeli, M; Dierauer, S; Ramseier, L E (2009). Treatment of reduced femoral antetorsion by subtrochanteric rotational osteotomy. Acta Orthopaedica Belgica, 75(4):490-496.

Abstract

The purpose of this study was to assess bone healing and complication rate following subtrochanteric rotational osteotomy fixed with a 4.5/5.0 Locking Compression Plate (LCP, Synthes) for reduced femoral antetorsion with early full weight bearing. The effects of the osteotomy on the range of internal rotation of the hip and complaints due to reduced antetorsion were also recorded. Between July 2004 and October 2007, 25 children (39 hips) with a mean age of 13 years (range, 9-18 years) were treated for reduced internal rotation of the hip by a subtrochanteric rotational osteotomy. Four patients (six hips) were excluded from this study due to concomitant surgeries prohibiting full weight bearing. Of the 21 patients who were allowed full weight bearing, nine had a unilateral and twelve a single-stage bilateral correction. We investigated time to union, implant failure, and complication rate as well as improvement in the range of internal rotation. All osteotomies healed without secondary displacement or angulation. Internal rotation improved from a mean of 8.6 degrees (-5 degrees to 20 degrees) preoperatively to 37.3 degrees (25 degrees to 60 degrees) postoperatively. We noted no complication related with the femoral osteotomy. Subtrochanteric rotational osteotomy appeared as a reliable procedure to improve internal rotation of the hip. Fixation with 4.5/5.0 LCP allows simultaneous bilateral correction and immediate full weightbearing with crutches, with a minimal risk of implant failure.

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.
