Analysis of healthy glenohumeral arthrokinematics using four-dimensional computed tomography throughout internal rotation and forward elevation.

ABSTRACT:

Background

The glenohumeral (GH) joint is the most mobile joint in the human body and can translate, as well as rotate in its socket. Currently, it is not well established in literature how much the healthy humeral head translates, and how that changes overtime as people age. The objective of this study is to quantify GH joint proximity and translation in healthy participants and determine if there are any age-related, position-related, or direction-related differences.

Methods

Thirty-one participants were recruited for this study and split into 2 cohorts: young (aged ≤ 37 years) and old (aged ≥ 45 years). Four-dimensional computed tomography scans were taken as these participants completed internal rotation (IR) to the back and forward elevation. Three-dimensional bone mode
