Medial malleolar window approach for varus-type tibial pilon fractures: a retrospective study.
Article in BMC musculoskeletal disorders, 2023. 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
purposeChoosing a suitable surgical approach is crucial and challenging for type C pilon fractures. This article aims to explore the clinical efficacy of the medial malleolar window approach for varus-type tibial pilon fractures.
methodsA retrospective analysis was conducted on 38 patients with type C varus-type pilon fractures treated between May 2018 and June 2021. In total, 16 cases underwent surgical treatment through the medial malleolar window approach and 22 cases were treated with the traditional anteromedial approach combined with a posterior approach. The operation time, hospitalization time, fracture healing time, the American Orthopedic Foot and Ankle score, Visual Analogue Scale, and complications were recorded to comprehensively evaluate the clinical efficacy of the technique. Fracture reduction quality was evaluated using the criteria proposed by Burwell and Charnley.
resultsAll patients were followed up. No patients presented delayed union or nonunion. Compared with the conventional approach, the medial malleolar window approach had the advantage of better clinical effect recovery and better fracture reduction (P < 0.05). Meanwhile, the medial malleolar window approach had a shorter operation time, although the statistics suggest no significant difference with the control group. No implant exposure or infection occurred. There was good wound healing at two weeks after surgery in all but two cases. Local wound edge necrosis developed in one case in the medial malleolar window approach group, and the wound could not be closed at one stage in another case in the conventional group because of excessive tension, requiring secondary closure.
conclusionThe medial malleolar window approach provides excellent exposure to type C pilon fractures, allowing for satisfactory fracture reduction and functional rehabilitation. The medial window approach is recommended for varus-type pilon fractures, which can effectively avoid a posterior incision and reduce the operation time.
