ABSTRACT
BACKGROUND:
Glenoid bone loss and severe retroversion can pose difficulties when implanting a glenoid component for total shoulder arthroplasty for primary osteoarthritis. Mini-glenoid implants may be useful in the setting of severe glenoid wear in which a standard pegged glenoid component cannot be placed. MATERIALS ANDMETHODS:
This study is a retrospective review, performed over a 3-year period, of patients who received a total shoulder arthroplasty using an inset mini-glenoid in the setting of severe glenoid dysplasia and/or medial glenoid bone loss. We identified patients with a minimum of 2 years' follow-up and evaluated preoperative and postoperative range of motion, visual analog scale scores, Single Assessment Numeric Evaluation scores, complications, and patient satisfaction.RESULTS:
Seven patients (4 female and 3 male patients; 9 shoulders) with a mean age of 66 years were treated with the described procedure and had a mean follow-up of 34 months. There were 6 primary arthroplasties and 3 revision cases. Four shoulders were classified as Walch type A2 glenoids, 2 were classified as Walch type C, and 3 were unable to be classified. There was a statistically significant increase in range of motion (forward elevation, 48°; external rotation, 14°), decrease in pain scores (8 points to 1 point), and improvement in Single Assessment Numeric Evaluation scores (31.7% to 89.4%). The mean patient satisfaction score was 8.6 points on a 10-point scale.CONCLUSION:
At 2-year follow-up, total shoulder arthroplasty with a mini-glenoid component can offer adequate pain relief and functional results in the setting of glenoid bone loss or severe retroversion.Palabras clave
