Giant Morel-Lavallée lesion complicated with open pelvic fracture: a rare case report.
Article in Frontiers in surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: Morel-Lavallée lesion (MLL) is a rare closed degloving injury from high-energy shear/crush trauma, often linked to pelvic/acetabular fractures. Due to limited clinical awareness, it is highly prone to misdiagnosis, potentially causing severe complications like infection and skin necrosis. Existing literature rarely documents giant MLL with open pelvic fractures. This article reports such a case in an obese patient after heavy-object impact, aiming to enhance understanding and improve management of complex injuries. Case presentation: A 27-year-old male sustained lumbosacral giant MLL and open pelvic fracture from workplace heavy-object crush. The MLL was unrecognized for two weeks at another hospital. Upon transfer, he had hemorrhagic shock, fluctuating lumbosacral swelling, and localized skin necrosis. Imaging showed comminuted left iliac fracture with extensive soft tissue edema and gas. Management: A three-stage surgery was used. Stage 1: muscle debridement, fracture fixation, and vacuum-assisted closure (VAC) to address acute injury and control infection. Stage 2: debridement, antibiotic-loaded bone cement implantation, and continued VAC for osteomyelitis treatment and bone healing. Stage 3: flap reconstruction and skin grafting to restore soft tissue integrity. Outcome: The patient was discharged one month postoperatively with viable skin grafts. At 3-month follow-up, fracture and wound healed well, confirming the staged approach's effectiveness. Conclusion: MLL is often overlooked in high-energy trauma, emphasizing early comprehensive exams plus imaging to avoid misdiagnosis. For MLL with fractures, staged treatment is advisable: early radical debridement and VAC to control infection, followed by fixation and soft tissue reconstruction when stable. VAC reduces infection risk by minimizing exudation and promoting granulation. Obese patients, with loose adipose compartments, face higher MLL risk and need special attention. Future research should explore minimally invasive techniques to optimize outcomes.
