Arthroplasty for post-traumatic carpometacarpal joint (CMC) V osteoarthritis with minced cartilage: a case report.
Article in Innovative surgical sciences, 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
Objectives: Fractures and dislocations of the bases of the fourth and fifth metacarpal bones are rare, accounting for <1 % of all hand injuries. If left untreated or inadequately fixed, there is a risk of persistent pain, functional impairment, and post-traumatic osteoarthritis. While common surgical approaches such as arthrodesis or suspension arthroplasty have been described, data on alternative treatment options remain limited. Case presentation: This case report presents the first documented use of minced cartilage for treating post-traumatic CMC V osteoarthritis. A 17-year-old patient experienced persistent pain following fracture fixation with K-wires. After debriding arthrotomy, cartilage was harvested from the hamate bone, minced, and combined with platelet rich plasma before implantation. One year postoperatively, the patient showed improved joint space, complete pain relief, and restored hand function. Conclusions: Preliminary results suggest that minced cartilage may offer a promising alternative, but further studies are needed to confirm its long-term efficacy.
