Why the study?
Does computed tomography improve the assessment of loosening of pegged glenoid components compared to fluoroscopically guided conventional radiography in patients with total shoulder replacement?
Does computed tomography improve the assessment of loosening of pegged glenoid components compared to fluoroscopically guided conventional radiography in patients with total shoulder replacement?
Computed tomography is more sensitive and reproducible than conventional radiography for detecting glenoid component loosening in total shoulder replacement.
CT may warrant consideration for glenoid loosening assessment after shoulder arthroplasty; leaves open effects on management or outcomes.
Computed tomography provided a more sensitive and reproducible tool for the assessment of loosening of pegged glenoid components than did fluoroscopically guided conventional radiography. Further improvement in implant design and fixation technique appears to be necessary for long-term success of cemented glenoid components.
