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 .
Short stem shoulder replacement
Context : It is agreed that it is important to anatomically reproduce the proximal humeral anatomy when performing a prosthetic shoulder replacement . This can be difficult with a long stemmed prosthesis , in particular if there is little relationship of the metaphysis to the humeral shaft . The ‘ short stem ’ prosthesis can deal with this problem . Aims : A prospect i ve study assessed the results of total shoulder arthroplasty using a short stem humeral prosthesis , a ceramic humeral head , and a pegged cemented polyethylene glenoid . Material s and methods : Patients with primary shoulder osteoarthritis were recruited into this prospect i ve trial and pre-operatively had the ASES , Constant , SPADI , and DASH scores recorded . The patients were clinical ly review ed at the two weeks , eight weeks , one year , and two year mark with completion of a data form . Radiological evaluation was at the eight week , one year and two year follow-up . At the one and two year follow-up the satisfaction rating , the range of passive and active motion , Constant , ASES , SPADI , DASH and pain results were recorded and analysed with SPPS 20 . Results : During the study period 97 short stem , ceramic head total shoulder replacements were carried out . At the time of follow-up 12 were two years from operation and 38 one year from operation . Active elevation was overall mean 160 degrees . Constant scores were 76 at 1 year , and 86 at 2 years , ASES 88 and 93 , and satisfaction 96 % and 98 % respectively at one and 2 year follow up . There were no problems during insertion of the humeral prosthesis , or any radiolucent lines or movement of the prosthesis on later radiographs . Conclusion : The short stem prosthesis had no complications , and on follow up radiographs good bone fixation . These fairly short term clinical results were overall good
