Shoulder function after helical long PHILOS plate

In order to minimize the risk of damaging the radial nerve while using a long PHILOS plate for proximal humerus fractures, recent studies have proposed twisting the plate in a helical form. This implies a modified surgical approach being yet unclear whether it leads to different middle to long-term shoulder function. This study compares the one-year shoulder functional outcomes of both techniques (helical vs. control).

In this retrospective comparative study, we analyzed 30 patients that fit the inclusion criteria, being 14 treated with a helical plate and 16 with a conventional straight long PHILOS plate. The primary endpoint was the normalized constant score after a minimum follow up of one year.

Both groups had a good one-year shoulder function, and no significant difference between the normalized constant scores was seen. There was no significant difference in the surgical complications as well.

Opting for a helical long PHILOS plate in order to avoid radial nerve damage provided a safe treatment with similarly good one-year shoulder function compared to straight PHILOS plates.
