Extra-axial chordoma in the distal fibula and the importance of ankle reconstruction.

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
introductionExtra-axial chordomas are extremely rare tumours that are characterised by slow growth and local aggressiveness and can potentially metastasise during follow-up. MATERIALS AND
methodsThis is the case of a 37-year-old woman with a bone lesion in the distal third of her fibula, with mild symptoms at that site consisting of a mass and mild pain. After local and distant staging, a percutaneous core needle biopsy was performed and a diagnosis of malignant bone tumour with cartilage differentiation was made, although the diagnosis and lesion grade could not be specified.
resultsAfter evaluation by the sarcoma committee, and given the biopsy diagnosis and negative distant extension, wide resection and reconstruction of the tibio-fibular reconstruction complex were performed. The definitive diagnosis was a well-differentiated extra-axial chondroid bone chordoma in the cortex of the fibula. Four years after the procedure, the patient is disease free, with good ankle function and independent in her activities of daily living. An AOFAS score of 62 points, an MSTS-ISOLS score of 18 points (60%) and SF-12 scores of 35.56 on the PCS and 24.58 on the MCS were recorded.
conclusionBone and soft tissue neoplasms require local and distant staging prior to biopsy. For a suspected diagnosis, clinical, anatomical and radiological correlation must be maintained. Treatment can proceed after the case has been reviewed by a multidisciplinary sarcoma committee. In chordoma cases, extra-axial locations are extremely rare. Reconstruction of the ankle presents major anatomical difficulties, with multiple techniques having been described. In such cases, a careful pre-surgical anatomical study must be performed to obtain wide margins and plan the reconstruction based on the type of patient, anatomical structures after resection and the multiple techniques described for the lateral ankle region, in order to maintain maximum function without limiting the patient's quality of life.
