Case Report: A case of functional reconstruction of second metacarpal following complex trauma with free fibula flap and silicone arthroplasty.
Article in Frontiers in surgery, 2025. 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
Complex metacarpal fractures with segmental bone loss and joint involvement pose significant challenges for the hand trauma surgeon. When traditional techniques are inadequate, microsurgical reconstruction and joint arthroplasty may offer a viable alternative. We report the case of a 32-year-old male who sustained a high-energy injury to the right hand, resulting in a comminuted fracture of the second metacarpal head and extensive dorsal soft tissue loss. After initial management, reconstruction of the second metacarpal was performed using a free osteocutaneous fibula flap. Although the vascularized bone graft was sculpted to settle in the metacarpophalangeal joint, mobility was not preserved. A staged silicone MCP arthroplasty then was later performed to improve joint mobility. At 18 months follow-up, the patient showed good soft tissue coverage, restored grip strength and proximal interphalangeal joint motion, but improvement in MCP range of motion remained partial despite arthroplasty. This article highlights the potential and limitations of combining vascularized bone transfer with prosthetic joint replacement in high-demand patients following trauma.
