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.

Abstract

purposeTreating acetabular fractures with open reduction and internal fixation (ORIF) may lead to poorer outcomes in older patients. As data for osteoporotic acetabular fractures are limited, we compared primary total hip replacement (THR) with ORIF for treating osteoporotic acetabular fractures, including those with posterior column instability.

methodsAll patients with osteoporotic acetabular fractures, treated with ORIF or primary THR from 2005 to 2015, were assessed retrospectively for clinical and radiologic outcomes. Indication criteria for selecting primary THR were evaluated.

resultsTwenty-three patients were treated with ORIF and nine with primary THR (performed with an anti-protrusion cage). If the posterior column was unstable, THR was combined with posterior column bridge plating. Indications for THR were the presence of a comminuted fracture pattern, approach-related risk factors for ORIF, and mobilization issues. Biomechanical reconstruction was acceptable with THR. Acetabular component loosening was observed only once. Secondary THR was indicated in 45 % of the ORIF cases. DISCUSSION: ORIF for acetabular fracture in older patients is unsatisfactory and may be even worse for osteoporotic fractures. Immobilization for long-term restricted weight bearing after ORIF is hazardous. Primary THR may enable early post-operative full weight-bearing. Various techniques, affording fixation of the unstable acetabular columns, are described. In THR with an anti-protrusion cage, only dorsal column instability needs to be addressed.

conclusionThe described technique achieved sufficient acetabular component stability. Primary THR with an anti-protrusion cage is an advantageous option to ORIF and should be strongly considered for osteoporotic acetabular fractures.
