The ideal glenohumeral radial mismatch following anatomic total shoulder arthroplasty TSA remains ill defined, with biomechanical and clinical studies recommending a range between 4 and 10 mm.
This study evaluates the effect of radial mismatch on the formation of radiolucent lines after TSA. We evaluated TSAs at a mean follow-up of 5. All TSAs were performed using a single implant system that allows radial mismatch between 3.
Shoulders were retrospectively evaluated for radiographic glenoid loosening according to the Lazarus score. Shoulders were evaluated according to radial mismatch: 3. At similar follow-up times, all groups demonstrated a similar incidence of glenoid radiolucencies and similar mean Lazarus scores.
Shoulders in female patients were more commonly treated with implant combinations resulting in 4. Variation in mismatch between 3.
This finding suggests that optimal radial mismatch may extend below 5. Keywords: Mismatch, glenoid loosening, loosening, outcomes, patient-reported outcomes, shoulder arthroplasty. Anatomic shoulder arthroplasty designs continue to exhibit variations in radial mismatch between 1 and 38 mm. Clinical work by Walch et al 33 documented lower rates of radiolucent lines with radial mismatch between 6 and 10 mm.
