1 · What the graph read from it

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.

2 · The registry

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

purposeLoss of independence is a major issue for quadriplegic patients. Restoring active wrist extension is essential to improving their autonomy. We aim to evaluate the feasibility of neurotization of the brachialis muscle nerve on branches destined to the extensor carpi radialis muscles.

methods30 upper limbs were dissected to analyze the anatomy and morphometry of the radial nerve, the musculocutaneous nerve, and the distance between the brachial nerve and the nerve branches of the radial extensor muscles of the carpus.

resultsThere was a variability in the positioning and number of nerve branches in the muscles studied. Neurotization requires an interposed nerve graft, with an estimated average length of 83 mm for the Extensor Carpi Radialis longus and 121.5 mm for the Extensor Carpi Radialis Brevis.

conclusionrestoring wrist extension through a neurotization of the Extensor Carpi Radialis Brevis is feasible. This non-mutilating technique could restore wrist extension. It is indicated for patients with high or moderate tetraplegia, where elbow flexion and extension are preserved. However, further clinical studies are needed to evaluate the efficacy and long-term results of this technique. LEVEL OF EVIDENCE: Level IV.
