Excerpt
Morphologic features in primary glenohumeral osteoarthritis do not appear in the same ways in all patients. Neer et al. [
21] noted that posterior glenoid wear and posterior humeral head subluxation commonly occur in primary glenohumeral arthritis. Using linear measurements with CT, Friedman et al. [
7] reported their observations of excessive glenoid retroversion. Despite acknowledgment of the various glenoid morphologic features and glenohumeral relationships that are associated with glenohumeral arthritis [
7,
21], it was only in 1999 that Walch et al. [
29] classified these commonly observed features. In an effort to clarify etiology, progression, and treatment, Denard and Walch [
4] and Walch et al. [
29] used CT to classify morphologic features of the glenoid in primary glenohumeral osteoarthritis based on the concepts of glenoid version and the glenohumeral subluxation index. …
