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

backgroundMalignant tumors originating in the talus are rare and present significant challenges in reconstruction. Traditional treatments, such as below-knee amputation or tbiocalcaneal fusion, often result in significant loss of ankle function. After tumor resection, reconstruction of the talus and calcaneus is necessary to preserve ankle function. However, the intricate anatomical structure and unique location of the talus and calcaneus present significant challenges for prosthetic reconstruction. CASE PRESENTATION: Here, we present the case of an 11-year-old adolescent patient diagnosed with Ewing's sarcoma of the talus, accompanied by suspected involvement of the calcaneus. Following a comprehensive evaluation, a 3D-printed talus-calcaneus prosthesis, which is composed of a ultrahigh-molecular weight polyethylene (UHMWPE) part and a titanium alloy part, was designed for talus and calcaneus reconstruction. In addition, a porous structure was designed to promote the integration of bone-prosthesis interface. The lesion was completely resected and the prosthesis was precisely installed. After 12 months follow-up, patients demonstrated favorable function results with the Musculoskeletal Tumor Society (MSTS) score was 27/30, and the American Orthopedic Foot and Ankle Society (AOFAS) score was 92/100. The range of motion for dorsiflexion, plantarflexion, inversion, and eversion of the right ankle joint was measured as 10° and 35°, 15°, and 10°, respectively. The postoperative radiograph showed a good position of the prosthesis. No narrowed joint space was observed. Tomosynthesis shimadzu metal artifact reduction technology (T-SMART) revealed that integration between bone and prosthesis was good.

conclusionIn this case, we present a case of 3D-printed talus-calcaneal prosthesis reconstructing talus and calcaneus. Favorable postoperative function outcome and good integration of the interface were observed. Therefore, this case provides an alternative therapeutic option for the treatment invasive talus tumor accompanied by suspicious contamination of the calcaneus. Nevertheless, a larger cohort study and with longer follow-up is needed to evaluate the effectiveness and potential complications of this novel prosthesis.
