Impact of femoral stem alignment on periprosthetic bone density in THA: a study of the Avenir Complete stem.
Article in Archives of orthopaedic and trauma surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThigh pain, aseptic loosening, and failure after total hip arthroplasty has been reported. Therefore, this study examines the impact of femoral stem alignment on periprosthetic bone mineral density (BMD) in THA using the Avenir Complete cementless stem, focusing on the role of precise stem alignment in maintaining proximal femoral BMD. MATERIALS AND
methodsConsecutive patients who received the Avenir Complete stem via mini anterolateral approach in the supine position between March 2019 and March 2022 were included. Dual-energy X-ray absorptiometry was used to assess BMD changes, and computed tomography scans were used to evaluate stem alignment.
resultsBMD was maintained in the distal femur, but showed a slight decrease in the proximal femur. A negative correlation was observed among varus malalignment, anteversion errors, and changes in BMD in the proximal femur.
conclusionsThe findings underscore the importance of accurate stem positioning in THA, particularly in avoiding varus malalignment and anteversion errors, as misalignment can adversely affect proximal femoral BMD and potentially lead to early stem loosening. This study enhances the understanding of the influence of the Avenir Complete stem on postoperative BMD, highlighting the need for precise alignment to optimize outcomes.
