Three-dimensional analysis of the proximal radial shaft and its intramedullary canal: a cadaver imaging study.

ABSTRACT:

Background

The proximal radius (PR) spans from the radial head (RH) to the bicipital tuberosity. Numerous studies have described this morphology. However, much of the existing work oversimplifies the morphology; for example, modeling the radial neck and/or tuberosity as cylinders, excluding the intramedullary canal (IC) from analysis, and basing models on two-dimensional imaging. The IC is important for radial arthroplasty implant stem selection. The purpose of this study is to quantify the morphology of the PR with a focus on the IC, utilizing the analysis of 3-dimensional models. We stratify the study population into age, sex, and height groups to capture the variance expected in the general population. We hypothesize that IC morphology differs significantly between age, sex, and
