Proximal Row Carpectomy for Established Post-Traumatic Radiocarpal Arthritis Following Distal Radius Volar Rim and Scaphoid Fractures: A Case Report.
Article in Journal of orthopaedic case reports, 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
Introduction: Post-traumatic radiocarpal arthritis can occur as a result of complex wrist injuries. Distal radius volar rim fractures associated with scaphoid fractures can result in progressive cartilage degeneration, pain, loss of motion, and functional impairment. Malunited distal radius volar rim fractures, where optimal stabilization is not done, can lead to radiocarpal incongruity and early post-traumatic radiocarpal arthritis. Proximal row carpectomy (PRC) remains a valuable motion-preserving salvage procedure for selected patients with advanced radiocarpal arthritis. Case Report: A 32-year-old male presented 4 months after a motorcycle-related injury with persistent right wrist pain, reduced grip strength, difficulty performing fine motor tasks, and limitations in lifting heavy objects. He had sustained a distal radius volar rim fracture and scaphoid fracture and developed radiocarpal arthritis. Clinical examination demonstrated pain aggravated by wrist motion and reduced grip strength. Arthroscopic evaluation confirmed significant post-traumatic chondral degeneration of the radiocarpal joint. The patient underwent wrist arthroscopy, PRC, posterior interosseous nerve neurectomy, capsular interposition arthroplasty, and radiocapitate K-wire stabilization. He subsequently developed early post-traumatic radiocarpal arthritis due to inadequate fixation of the volar rim fragment. Conclusion: This case highlights the critical importance of recognizing and adequately fixing the distal radius volar rim (volar lunate facet) fragment during the initial management of wrist trauma. Failure to restore the volar buttress resulted in persistent radiocarpal incongruity and rapid progression to symptomatic post-traumatic radiocarpal arthritis within 4 months in a young patient. It demonstrates the role of PRC as a biomechanically sound salvage option for radiocarpal arthritis secondary to a missed or malunited volar rim fracture.
