Clinical and Radiologic Outcomes of NOVOSIS (rhBMP-2 With Hydroxyapatite Carrier) Grafting for Scaphoid Waist Nonunion: A Preliminary Clinical Study.
Article in Orthopaedic surgery, 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
objectiveScaphoid nonunion remains a challenging problem due to limited vascularity and carpal malalignment. Although autologous bone grafting remains the standard of care, donor-site morbidity and technical demands can be substantial. NOVOSIS, a composite of recombinant human bone morphogenetic protein-2 (rhBMP-2) and a hydroxyapatite (HA) carrier, has shown osteoinductive and osteoconductive potential in other orthopedic applications, but its clinical efficacy in scaphoid nonunion has not been established.
methodsSeven consecutive patients with scaphoid waist nonunion underwent fixation using two 2.3-mm headless compression screws and NOVOSIS application between August 2023 and December 2024. All patients were followed for a minimum of 12 months (mean 12.4 months; range 12-14). Clinical outcomes were assessed using visual analogue scale (VAS), range of motion (ROM), and Mayo Wrist Score (MWS). Radiographic parameters included lateral intrascaphoid angle (LISA) and scapholunate angle (SLA). Paired t-tests compared pre- and postoperative values.
resultsAll patients achieved radiographic union at final follow-up. VAS scores improved from 4.9 ± 1.2 to 0.4 ± 0.8 (p < 0.001), and MWS from 59.3 ± 7.3 to 94.3 ± 5.4 (p < 0.001). LISA improved from 51.7° ± 13.6° to 31.5° ± 5.1° (p = 0.007), and SLA from 65.7° ± 6.8° to 52.2° ± 8.8° (p = 0.006). No procedure-related complications, such as infection, ectopic bone formation, or donor-site morbidity, were observed.
conclusionThis preliminary clinical series demonstrated that NOVOSIS provided reliable union, functional recovery, and radiographic correction in scaphoid nonunion without donor-site morbidity. It may serve as a feasible alternative to autologous bone grafting and warrants further validation in larger studies.
