Stemless anatomic TSA result ed in similar functional outcomes and complication rates to stemmed TSA with decreased operative time and lower blood loss .
BACKGROUND Stemless anatomic total shoulder arthroplasty ( TSA ) is used in the treatment of osteoarthritis of the shoulder joint and other degenerative shoulder diseases .
It has several proposed advantages over stemmed TSA including increased bone preservation , decreased operative time , and easier removal at revision .
Impact of prosthetic design on clinical and radiologic outcomes of total shoulder arthroplasty: a prospective study.
BACKGROUND This prospect i ve longitudinal study compared clinical and radiologic outcomes of  total shoulder arthroplasty ( TSA )  using 3 different prosthetic design s , the Neer II system , the Bigliani-Flatow ( BF ) , and a stemless prosthesis , the Total Evolutive Shoulder System ( TESS ) . MATERIAL S AND METHODS Patients with advanced osteoarthritis of the glenohumeral joint who underwent TSA  were followed up for 2 years . Four patient-oriented disability outcomes were used . The clinical data collected before surgery and at follow-up assessment s during a 2-year period included active range of motion ( ROM ) in 6 directions and strength . Radiographic signs of glenoid and humeral component loosening were recorded . The incidence of humeral head subluxation was documented . RESULTS Seventy-four patients completed the study . There was a significant improvement in the 4 disability measures , ROM , and strength at 2 years in all 3 groups ( P < .0001 ) . Active external rotation at 90 ° abduction was statistically significantly lower in the Neer II group ( P = .001 ) . The incidence of lucent lines around the glenoid component was higher in the Neer II group ( P = .0002 ) . No statistically significant relationship was seen between type of prosthesis and patient satisfaction ( P > 0.05 ) . CONCLUSIONS The 3 types of TSA prostheses used in this study all provided significant improvement in pain and function and were associated with high patient satisfaction . The Neer II was associated with less active external rotation and more lucent lines
