The use of intraoperative cell salvage in total hip arthroplasty with subtrochanteric shortening osteotomy for the treatment of high hip dislocation: a retrospective cohort study.
Article in BMC musculoskeletal disorders, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIntraoperative cell salvage (ICS) is an important component of blood management in patients undergoing orthopedic surgery. However, the role of ICS is less well defined in total hip arthroplasty (THA) with subtrochanteric shortening osteotomy (SSO) which is a common surgical technique to manage high hip dislocation. This study aimed to determine the effect of ICS during THA with SSO and to identify factors associated with the ability to salvage sufficient collection for reinfusion in patients with high hip dislocation.
methodsWe identified 178 patients who underwent THA with SSO for high hip dislocation between November 2010 and April 2021. The consecutive cohort was analyzed by logistic regression to determine the effect of ICS on postoperative allogeneic blood transfusion (ABT) and to explore the associations between patient demographics, clinical and radiographic characteristics, preoperative laboratory examination, and surgical variables with the ability to generate adequate blood salvage to reinfuse.
resultsIn the consecutive cohort of 178 patients, cell salvage was reinfused in 107 patients (60.1%) and postoperative allogeneic red blood cell (RBC) transfusion within 3 days of implantation was administrated in 40 patients (22.5%). In multivariate analysis, the reinfusion of ICS (OR (95%CI) 0.17 (0.07-0.47)), center of rotation (COR) height ≥ 60 mm (OR (95%CI) 3.30 (1.21-9.01)), the length of SSO ≥ 30 mm (OR (95%CI) 2.75 (1.05-7.22)) and the use of drainage (OR (95%CI) 2.28 (1.04-5.03)) were identified as independent factors of postoperative allogeneic RBC transfusion. In addition, the following variables were identified as independent factors associated with the ability to generate sufficient blood salvage volume for reinfusion: COR height ≥ 60 mm (OR (95%CI) 3.47 (1.58-7.61)), limb-length discrepancy (LLD) ≥ 25 mm (OR (95%CI) 2.55 (1.15-5.65)) and length of SSO ≥ 30 mm (OR (95%CI) 2.75 (1.33-5.69)).
conclusionsICS was efficacious in reducing the exposure rate of postoperative RBC transfusion for high hip dislocation during THA with SSO. In addition, patients with greater COR height, larger LLD, and longer length of SSO were predisposed to generate sufficient collection for reinfusion in THA with SSO.
