Recently published results showed advantages, such as fewer complications, when a convertible-platform humeral stem was used during conversion of a total shoulder arthroplasty to a reverse total shoulder arthroplasty.

Lynn A. Crosby, MD, and colleagues categorized 102 patients who underwent revision of an anatomic shoulder arthroplasty to a reverse total shoulder arthroplasty into patients who needed exchange of the humeral stem (n=73; exchange group) and patients who retained a convertible-platform humeral component (n=29; retention group). Researchers compared patient demographics, operative time, blood management, range of motion, complications and patient-reported outcomes between the two groups.

Results showed patients in the retention group had significantly shorter operative times, as well as significantly less estimated blood loss. However, researchers did not find a significantly smaller percentage of patients who received blood transfusions or significantly less decreases in hemoglobin and hematocrit levels.

At 2 years follow-up, both groups had improvements in ASES and Constant scores, according to results. Although patients in the retention group had a significantly lower prevalence of intraoperative complications, researchers noted no differences in the rate of reoperation between the retention and exchange groups. – by Casey Tingle
