Ultra-short stem intercalary prosthetic reconstruction for joint preservation in metaphyseal tumor management: a retrospective review of twenty-five cases.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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
purposeThis study evaluates the outcomes, survival, and ASL incidence of ultra-short stem intercalary prosthetic reconstruction for tumors involving the metaphysis of bone.
methodsA retrospective analysis of 25 patients treated at two centers with wide resection for primary or metastatic bone tumors (femur, tibia, humerus) followed by reconstruction using ultra-short stem intercalary prostheses combined extracortical plates. Clinical outcomes were assessed using the Visual Analogue Scale (VAS) and Musculoskeletal Tumor Society (MSTS) score. Survival rates were calculated using the Kaplan-Meier method, and complications were classified according to the Henderson system.
resultsThe mean follow-up was 20.2 months (range, 3-101 months). The average length of the ultra-short stems was 41.3 ± 9.6 mm. Mean operative time was 164 ± 61.3 min, blood loss averaged 646.4 ± 375.5 ml and the mean defect size was 122 ± 52.1 mm. Postoperative VAS scores were significantly lower than preoperative levels (P < 0.05). The mean MSTS score was 24.2 ± 3.5 (range, 15-29). Kaplan-Meier analysis revealed prosthesis survival rates at 1, 2, 3, and 5 years of 91.7%, compared to patient survival rates of 74.5%, 52.7%, 52.7%, and 52.7%. Postoperative complications occurred in 12% of patients (3/25), including one case of aseptic loosening (ASL), and two patients required reoperation.
conclusionsUltra-short stem intercalary prostheses with extracortical plates provide a viable, effective option for reconstruction of short bone stumps after tumor resection, offering improved functional outcomes and acceptable prosthesis failure rates.
