Free Osteocutaneous Fibular Flap for Hand Reconstruction Related to Clear Cell Sarcoma Resection: A Case Report.
Article in Cureus, 2026. 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
We present a 25-year-old female with a two-year history of clear cell sarcoma (CCS) of the hand. The patient presented with a painless left hypothenar tumor without neurological or functional compromise. MRI was compatible with sarcoma (4.8x3.4x4.9cm) and incisional biopsy confirmed CCS by immunohistochemistry (MITF1 and EWSR1 rearrangement both positive). The patient received preoperative radiotherapy for tumor reduction (approximately 80%). A wide resection was performed with negative margins of 2 cm, including third-fifth metacarpals, partial carpectomy and amputation of the fifth finger due to intraoperative ischemia. The lesion was reconstructed with a free fibula flap whose survival and postoperative short-term evolution were favorable. Six months after surgery, the patient presented partial mobility under rehabilitation with no evidence of recurrence or metastasis. Disabilities of the Arm, Shoulder and Hand (DASH), Musculoskeletal Tumor Society (MSTS) score, grip and pressure strength could not be determined. Our case is very particular due to the hypothenar involvement with central multistructural involvement and an atypical slow evolution. The aggressive therapeutic approach with microsurgical resection, reconstruction and functional preservation using a multisegmented fibula free osteocutaneous flap was favorable for the patient's outcome.
