Cellular Bone Matrix for the Treatment of Considerable Bone Loss in Two Metacarpal Fractures.
Article in Journal of hand surgery global online, 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
High-energy mechanisms that lead to hand fractures can create substantial bony defects that are not amenable to traditional treatments. Management options include autograft, allograft, and bone graft substitutes such as calcium sulfate/phosphate cements, which provide good results when used appropriately however each strategy has limitations. Cellular bone matrices (CBMs) are newer graft substitutes designed to supply osteogenic cells along with scaffold and inductive factors. We present a case series of metacarpal fractures with considerable ballistic-related defects treated with CBM augmentation. Two male patients (mean age 32 years) sustained second metacarpal fractures from high-caliber ballistic injury and were followed for 19 months. One required later tenolysis and dorsal capsulotomy for stiffness. Both demonstrated full radiographic union and CBM incorporation on computed tomography. This series shows excellent radiographic outcomes using CBM for metacarpal defects. Although further study is needed, to our knowledge, this is the first published evidence supporting CBM as an effective option for these injuries.
