Bone Grafting in Scaphoid Avascular Necrosis: A Systematic Review Comparing Distal Radius and Iliac Crest Donor Sites.
Review in Cureus, 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
Scaphoid nonunion with proximal pole avascular necrosis (AVN) presents a significant surgical challenge due to compromised vascularity and limited healing potential. Bone grafting has emerged as an effective strategy, with donor site selection, distal radius versus iliac crest, being crucial to clinical outcomes. This systematic review evaluated five studies, including 262 patients (distal radius vascularized bone grafting (DR-VBG): 53; iliac crest grafts: 209), comparing DR-VBG and iliac crest grafts in scaphoid nonunion with AVN. DR-VBG consistently demonstrated faster union (7.9-8.6 months), superior anatomical restoration, and lower donor-site morbidity compared with iliac crest grafts, which, despite providing robust structural support, were associated with higher pain, gait disturbances, nerve injury, and scarring. Functional outcomes were comparable when union was achieved; however, DR-VBG showed subtle advantages in carpal alignment and long-term wrist biomechanics. These findings support DR-VBG as the preferred donor site in AVN-complicated scaphoid nonunion, while iliac crest grafts remain a viable option when greater structural volume is required.
