Surgical complications and implant survival of the Osseointegrated Prostheses for the Rehabilitation of Amputees system in patients with combat-related limb loss: a retrospective cohort study.
Article in International orthopaedics, 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
purposeTo assess implant survival, postoperative complications, and infection-related risk factors in veteran amputees treated with a bone-anchored prosthetic system.
methodsThis retrospective study analysed clinical data from 49 veterans of the Russo-Ukrainian war who underwent implantation of the Osseointegrated Prostheses for the Rehabilitation of Amputees (OPRA) system for upper or lower limb amputation in 2023-2024. Implant survival and complication rates were analysed at one-year follow-up after the second surgical stage (S2).
resultsThe first stage of OPRA was performed in 49 patients (51 implants): 21 transfemoral, 27 transhumeral, and transtibial. Three patients declined S2, and one humeral implant was explanted after S1. The S2 was completed in 45 patients (47 implants). At one-year follow-up after S2, implant survival was 97.9% with one of 47 implants explanted because of septic loosening. Infectious complications occurred in 18% of patients, including Grade 4 infection in 2%. Beyond one year (median follow-up, 18.7 months), two additional implants were explanted (periprosthetic fracture, n = 1; septic loosening, n = 1).
conclusionOPRA implantation in veteran amputees demonstrated favourable short-term implant survival (97.9% at one-year follow-up after S2), although longer-term follow-up is required.
