Anatomical analysis of different helical plate designs for proximal humeral shaft fracture fixation.

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
objectivesHelical plates are preferably used for proximal humeral shaft fracture fixation and potentially avoid radial nerve irritation.
aimsSafety of applying four different long plate designs (straight, 45°-, 90°-helical and ALPS) with MIPO technique as well as assessment and comparison of their distances to adjacent anatomical structures.
methodsMIPO was performed in 16 human cadaveric humeri using either a straight (group 1), a 45°-helical (group 2), a 90°-helical (group 3) plate, or an ALPS (group 4). Applying CT angiography, distances between brachial arteries and plates were evaluated. All specimens were dissected and distances to the axillary, radial and musculocutaneous nerve were evaluated.
resultsNo specimens demonstrated injuries of the anatomical structures at risk after MIPO with all investigated plate designs. Closest overall distance (mean (range); mm) between each plate and the radial nerve was 1 (1-3) in group 1, 7 (2-11) in group 2, 14 (7-25) in group 3 and 6 (3-8) in group 4. It was significantly bigger in group 3 and significantly smaller in group 1 compared to all other groups, p < 0.001. Closest overall distance between each plate and the musculocutaneous nerve was 16 (8-28) in group 1, 11 (7-18) in group 2, 3 (2-4) in group 3 and 6 (3-8) in group 4. It was significantly bigger in group 1 and significantly smaller in group 3 compared to all other groups, p < 0.001.
conclusionsMIPO with 45°- and 90°-helical plates as well as with ALPS is safely feasible and demonstrates significantly bigger distances to the radial nerve compared to straight plates. However, the distances remain small and attention must be paid to the musculocutaneous nerve and the brachial artery when MIPO is applied using ALPS, 45°- and 90°-helical implants.
