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

purposeThis study aims to investigate the suitable surgical strategies for applying TaBw01 porous tantalum rod across different stages of osteonecrosis of the femoral head (ONFH).

methodsTaBw01 tantalum rods were fabricated using type FTaY-1 tantalum powder via the foam impregnation-sintering method. Mechanical testing with the Instron 8801 universal testing machine and finite element analysis (FEA) assessed single tantalum rod implantation and impaction bone grafting combined with rod implantation. A total of 86 osteonecrosis of the femoral head (ONFH) patients (94 hips) were treated: the experimental group (45 patients, 50 hips) underwent surgical hip dislocation (SHD) with impaction bone grafting and tantalum rod implantation, while the control group (41 patients, 44 hips) received single rod implantation. Primary failure criteria included femoral head collapse (≥ 2 mm) or total hip arthroplasty. Patient-reported outcomes (PROs), including Harris Hip Score (HHS), Visual Analog Score (VAS), Hip Outcome Score Activities of Daily Living Subscale (HOS-ADL), and Hip Outcome Score Sport-Specific Subscale (HOS-SSS), were analyzed based on Minimum Clinically Important Difference (MCID).

resultsFEA confirmed stresses below the material's yield and compressive strength. At 3 years, survival rates for ARCO (Association Research Circulation Osseous) stage IIb and IIc were higher in the experimental group (100%, 80.38%) than the control group, while stage IIa survival was 100% in the control group. The experimental group also had higher MCID attainment for HHS, HOS-ADL, and HOS-SSS.

conclusionsCompared with single TaBw01 implantation, impaction bone grafting combined with TaBw01 implantation via SHD demonstrated superior outcomes for ARCO stage IIb and IIc, with a minimum 2-year follow-up. while single TaBw01 implantation may be more suitable for stage IIa. This study emphasizes the importance of combining biological and biomechanical reconstruction in ONFH treatment.
