A Comparison of Three Different Surgical Treatments in Late Stage Kienböck's Disease.

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
Objective: Different treatment options exist for the late-stage Kienböck disease (KD). The functional outcomes of patients undergoing scaphocapitate fusion (SCF), tendon ball arthroplasty (TBA), and radius metaphyseal core decompression in stages 3 to 4 KD were investigated. Materials and Methods: This is a retrospective study spanning ∼11 years, conducted at our clinic, involving the operated patient KD. The study included 51 patients with an average follow-up duration of 68 months (range: 16-130 months). Patients who underwent SCF, TBA, and radius metaphyseal core decompression were divided into three groups based on the surgical approach. The range of motion of the wrist joint and grip strength of the operated wrists were assessed alongside the unaffected wrist during follow-up evaluations. Satisfaction levels among patients were measured by comparing groups internally and based on disease stages. Functional outcomes were evaluated using quick disabilities of the arm, shoulder, and hand (Q-DASH) and Mayo wrist scoring scales. Results: Of the patients, 28 were female (54.9%) and 23 were male (45.1%). The mean age was 34 years (range: 19-62 years). There were 12 patients (23.53%) in the radial decompression group, 10 patients (19.61%) in the SCF group, and 29 patients (56.86%) in the TBA group. When the wrist joint Range of motion (ROM)s are analyzed, the losses in both stages 3A and 3B disease are significant compared with the intact wrist in all three surgical methods. When the groups were compared, a higher loss of wrist joint ROM was observed in the TBA group, especially in Kienböck stage 3B patients ( Conclusion: KD is surgically treated with various operations identified. In terms of functional outcomes, all three surgeries are considered satisfactory. However, in young and active patients, even in advanced stages of the disease, metaphyseal core decompression should be attempted as an initial treatment due to its easier approach and the avoidance of direct manipulation of the carpus.
