Supports CT for glenoid assessment after shoulder arthroplasty; leaves open effects on revision decisions or outcomes.
Observational (n=43)
Absolute Event Rate: 76.6% vs 44.7%
Computed tomography is more sensitive and reproducible than conventional radiography for assessing loosening of pegged glenoid components in total shoulder replacement.
Yian et al. (2005) conducted an observational in Total shoulder replacement (n=43). Computed tomography vs. Fluoroscopically guided conventional radiography was evaluated on Detection of lucencies around the glenoid component. Computed tomography detected glenoid lucencies in 76.6% (36/47) of shoulders compared to 44.7% (21/47) with conventional radiography at an average of 40 months after total shoulder replacement.
