Distal Humerus Fractures in Maintenance Hemodialysis Patients with Forearm Arteriovenous Shunts: Two Case Reports.

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
BACKGROUND Surgical management of distal humerus fractures in hemodialysis patients with an ipsilateral arteriovenous shunt is challenging due to shunt injury and bleeding risks. Treatment selection requires careful patient evaluation and arteriovenous fistula (AVF) preservation. This report describes 2 such cases managed with open reduction and internal fixation using locking plates. CASE REPORT Case 1: A 62-year-old man with chronic renal failure sustained an AO type C1 distal humerus fracture in the shunt-bearing limb. Surgery was performed in the supine position without a tourniquet, using medial and lateral approaches with double locking plates. At final follow-up, elbow motion was 120° flexion, 0° extension, 90° pronation, and 90° supination. Grip strength was 77.3% of the contralateral side. The visual analog scale (VAS), Quick Disabilities of the Arm, Shoulder, and Hand (Q-DASH) score, and Mayo Elbow Performance Score (MEPS) were 0, 0, and 100, respectively. Radiographs confirmed bone union. Case 2: A 64-year-old woman with chronic renal failure sustained an AO type A2 fracture in the shunt-bearing limb. The same surgical approach was used. At final follow-up, elbow motion was 135° flexion, -5° extension, 85° pronation, and 85° supination. Grip strength was 100% of the contralateral side. The VAS, Q-DASH, and MEPS were 1, 9.09, and 85, respectively. Radiographs confirmed bone union. CONCLUSIONS Locking plate fixation via medial and lateral approaches in the supine position, without tourniquet use, produced favorable outcomes in both cases. This technique may help to preserve AVF function while ensuring stable fixation and satisfactory functional recovery.
