1 · What the graph read from 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.

2 · The registry

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

purposeLong stems with diaphyseal fixation are widely used in revision total hip arthroplasty (RTHA) but may increase surgical complexity and compromise femoral bone stock. Primary femoral stems, used as a de-escalation strategy, could simplify RTHA in selected patients as a bone preserving strategy. This study aimed to evaluate the clinical and radiographic outcomes of this technique using a cementless rectangular-taper shortened stem during both components RTHA.

methodsBetween January 2019 and January 2025, 301 both components RTHA were prospectively included in our institutional total joint registry. Among them, 23 RTHA (20 patients, 14 men, mean age at revision = 63 years [54-71]) with femoral de-escalation with the use of a cementless rectangular-taper shortened stem and a dual mobility cup construct were identified and retrospectively reviewed at latest follow-up, focusing on complications related to this reconstruction technique. Clinical outcome was evaluated with the Harris Hip Score (HHS).

resultsAt a mean follow-up of 48 months (23-75), no postoperative periprosthetic fracture, mechanical failure or early loosening of the femoral reconstruction occurred. One early dislocation occurred at 41 days, managed by closed reduction without recurrence at latest follow-up. The mean HHS significantly improved from 70 (59-83) preoperatively to 94 (64-100) postoperatively, with 96% of patients achieving HHS ≥ 80 at latest follow-up.

conclusionsIn selected patients undergoing RTHA with limited femoral bone loss, femoral de-escalation with a cementless rectangular-taper shortened stem demonstrated reliability for femoral reconstruction with no component-related complication and significant functional improvement at short-term follow-up.
