Preoperative Templating Prior to Total Hip Arthroplasty: A Closed-Loop Audit.
Article in Cureus, 2025. 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
backgroundPreoperative templating is an essential process in total hip arthroplasty (THA), aiding surgical planning and implant selection to optimize patient outcomes. Despite its significance, templating is inconsistently practiced, influenced by factors such as surgeon experience and institutional protocols. In light of increasing THA rates, this study aimed to assess adherence to templating guidelines within our institution and evaluate the impact of a new protocol on compliance.
methodsWe conducted a closed-loop audit with an initial review of 50 THA cases, assessing the frequency and timing of preoperative templating. Following the first audit cycle, a departmental protocol was introduced, mandating templating radiographs 7-180 days before surgery, supported by a departmental rota. In the subsequent audit cycle, another 50 patients were reviewed. Templating was performed using TraumaCad software (Orthocrat Ltd, Petach Tikva, Israel) on anteroposterior pelvic radiographs with a calibration sphere. Statistical analysis was conducted using Welch's unpaired t-test. Leg length changes were evaluated in all patients based on their two most recent radiographs during the second audit cycle to determine if leg lengths had changed over time.
resultsIn the pre-intervention cycle, only 20% of patients had templating radiographs within the recommended timeframe, with an average of 140 days between the most recent radiograph and surgery. Post-intervention, compliance improved significantly, with 70% of patients receiving templating radiographs within the specified period (p < 0.0001), and the average time between the most recent radiograph and surgery reduced to 33 days. A mean leg length change of 2.26 mm was observed, with changes ranging from 0 to 17 mm between radiographs. The mean interval between radiographs was 386 days.
conclusionThis closed-loop audit found that implementing booking preoperative templating radiographs prior to THA and integrating them as part of the preoperative assessment process had a significant impact on the number of patients having appropriate imaging performed preoperatively. Simple interventions, such as the introduction of a roster, helped ensure compliance in the booking of departmental radiographs. This study has shown how patient parameters can change over time and emphasizes the importance of ensuring up-to-date imaging to allow accurate surgical planning.
