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.

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

purposeDespite modern operative techniques and a considerable number of studies in the literature, the best treatment for calcaneal fractures remains an enigma for orthopaedic surgeons. The purpose of the study was to compare clinical and radiographic outcomes between anatomic calcaneal plate (ACP) fixation and crossed Schanz pin (CSP) fixation in the treatment of Sanders type II and III displaced intra-articular calcaneus fractures (DICFs).

methodsConsecutive 65 patients (49 males, 16 females) who underwent surgery for DCIFs between January 2009 and February 2013 were retrospectively evaluated. The patients were divided into two groups as ACP and CSP according to the operative technique. The groups were compared in terms of demographic features, injury mechanism, operation time, fluoroscopy exposure, complications, full weight-bearing time, functional, and radiological outcomes.

resultsVAS-rest score did not differ significantly between the groups while the VAS-activity score was significantly higher in the CSP group (p = 0.001 and p = 0.645, respectively). Foot Function Index (FFI) was significantly lower, Maryland Foot Score (MFS) and the American Orthopaedic Foot and Ankle Society-hindfoot score (AOFAS) were significantly higher in the ACP group (p = 0.047, p = 0.016, and p < 0.001, respectively). While no difference was observed between the preoperative and the early post-operative (1st day) Böhler angle and Gissane angle, both were significantly higher in the ACP group at the post-operative last control (p < 0.001 and p < 0.001, respectively).

conclusionAlthough crossed Schanz pin fixation shortens the operation time in displaced intra-articular calcaneus fractures compared to anatomic calcaneal plate, increased fluoroscopy exposure rates and low functional and radiological outcomes are disadvantageous of crossed Schanz pin. Anatomic calcaneal plate is still a better technique for preserving the alignment and elevating the displaced intra-articular segment for good to excellent mid-term results.
