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 .
Midterm results of stemless shoulder arthroplasty: a prospective study.
BACKGROUND This study evaluated the functional and radiologic results of shoulder arthroplasty using a single type of stemless humeral head implant  with a minimum follow-up of 5 years . METHODS  Stemless shoulder arthroplasties in 78 patients at a mean age of 58 years were prospect ively evaluated at a mean clinical and radiologic follow-up of 72 months . Functional results were documented using the age- and sex-adjusted Constant score with st and ardized radiographic examination . RESULTS The Constant score improved significantly from 38.1 % to 75.3 % ( P < .0001 ) . Active range of motion improved significantly for flexion ( from 114 ° to 141 ° ) , abduction ( from 74 ° to 130 ° ) , and external rotation ( from 25 ° to 44 ° ; P < .0001 ) . Bone mineral density was reduced in 34.9 % of the older population , without an influence on shoulder function ( Constant score without lowering of bone density ; 73 % ; Constant score with lowering of bone density 80 % ; P = .404 ) . The overall complication rate was 12.8 % , with an overall revision rate of 9 % . None of the stemless implants were revised for loosening . CONCLUSION The functional and radiologic results of the stemless shoulder arthroplasty are comparable to the third and fourth generation of st and ard stem arthroplasty
