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

objectiveTo investigate the factors, surgical treatment methods and clinical effect of internal fixation failure of intertrochanteric and subtrochanteric fractures.

methodsFrom June 2015 to May 2019, arthroplasty and internal fixation revision were used to treat 18 cases of internal fixation failure of intertrochanteric and subtrochanteric fractures. There were 10 males and eight females, with an average age of 67.3 years (38-92 years). The 16 cases of initial intertrochanteric fractures were classified according to AO/OTA:13 cases of A2 and 3 cases of A3, the other 2 cases were subtrochanteric fractures (Seinsheimer type IV). The internal fixation failure was treated with total hip arthroplasty (6 cases), bipolar hemiarthroplasty (4 cases), revision with proximal femoral lockingplate (4 cases) and extend intramedullary nail (4 cases).

resultsAll patients were followed up for an average of 24.7 months (range, 12 to 36 months). The average operative time was 111.4 min (range, 72 to 146 min) and the average intraoperative blood loss was 403.6 mL (range, 200 to 650 mL). The average time of fracture union was 6.9 months (range, 5 to 9 months) for cases of internal fixation revision. The operative time of the arthroplasty group was shorter than the revision group (P < 0.001), and the intraoperative blood loss of the arthroplasty group was less than the revision group (P = 0.001). The affected limb shortening of postoperative (0.21 ± 0.19 cm) was better than preoperative (2.01 ± 0.60 cm) (P < 0.001), while the limb shortening of the arthroplasty group (0.11 ± 0.21 cm) was less than the revision group (0.33 ± 0.09 cm) (P = 0.015). At the last follow-up, all injured limbs regained walking function, and the Harris hip score was 81.3 ± 9.4 points. The Harris score of postoperative was better than preoperative (33.4 ± 5.9 points) (P < 0.001), while there were no significant differences between the arthroplasty group and the revision group at 3 months (76.5 ± 8.5 vs 71.1 ± 10.6, P = 0.249), 6 months (80.9 ± 7.9 vs 78.9 ± 12.9,P = 0.687) postoperative and the last follow-up (80.5 ± 8.3 vs 82.3 ± 11.7, P = 0.716) respectively.

conclusionFor internal fixation failure of peritrochanteric fractures, young patients could accept internal fixation revision to restore normal anatomical structure, correct varus deformity and autograft; while elderly patients and patients with damaged femoral head could be treated with arthroplasty to restore walking function.
