Modification of External Fixator in Cross-Leg Flap: A Stabilizing Solution for an Optimal Outcome.
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
backgroundLower limb defects with single-vessel supply and with monophasic flow are difficult to reconstruct due to paucity of coverage options. The cross-leg flap remains a reliable salvage option in these settings. But maintaining the position for three weeks is cumbersome for both the patient and the flap. Any movement of the lower limb generates a shearing force at the flap inset, predisposing to partial flap necrosis and dehiscence. An external fixator helps both the stable fixation of the lower limbs and the prevention of stretch in the flap. We aim to describe a modification in the conventional external fixator to prevent maceration of the lower limbs and the flap, and also facilitate ease of dressing. MATERIALS AND
methodsWe assessed eight patients retrospectively who underwent cross-leg flap for post-traumatic leg defects, where an external fixator was applied for better flap stabilisation.
resultsAll patients were male with post-traumatic soft tissue defects in various regions of the leg and foot, with variable underlying vital structures exposed. The average age of the patients was 41 years, with a range of 16-55 years. An external fixator was applied in all cases, with a modification of an additional tubular rod used at the base to prevent the legs from contacting the bed, thus preventing maceration and difficulty in dressing. All flaps survived well, but with partial necrosis of the distal margin in two patients, which was managed with debridement and advancement of the flap. The donor site was skin grafted.
conclusionExternal fixator is a reliable option for stabilising lower limbs in cases of cross-leg flap reconstruction. With the modification, it not only stabilises the lower limbs but also helps in preventing maceration and increasing airflow.
