Distance of the posterior interosseous nerve from the radial head during elbow arthroscopy : an anatomical study

Purpose The aims of this study were to measure the distance of the posterior interosseous nerve (PIN) from the radial head (RH) and its variations with forearm movements. Methods Five fresh frozen cadaver specimens were dissected under arthroscopy. An anterior capsulectomy extended to the entire lateral compartment was performed. The need of soft tissue dissection to isolate the nerve in the extracapsular space was recorded. The distance between the nerve and the anterior part of the RH was t...

The posterior interosseous nerve crosses the radial head midline and increases its distance from bony structures with supination of the forearm

Background: This study investigated whether forearm movements change the relative position of the pos- terior interosseous nerve (PIN) with respect to the midline of the radial head (Rh) under direct arthroscopic observation.Methods: The PIN was identified in 10 fresh frozen cadaveric specimens dissected under arthroscopy. The forearm was moved first in full pronation and then in full supination, and the displacement of the PIN from medial to lateral with respect to the midline of the Rh was ...

Translation, cross-cultural adaptation, and validation of the Italian version of the Oxford Shoulder Instability Score

Purpose The Oxford Shoulder Instability Score (OSIS) is self-reported outcome measurement developed to evaluate shoulder instability taking into account also adaptive strategies. Valid, reliable, reproducible, and user-friendly translations of outcome measure instruments are needed to allow comparisons of international study results.Methods The Italian translation and cultural adaptation of the OSIS were completed using a Btranslation–back translation^ method and the final version was adminis...
