HP: hemiprosthesis; ATP: anatomic total prosthesis; RP: resurfacing prosthesis; RTP: reversed total prosthesis.
a
Percentage of HPs, TPs, RFs, and RTPs that were cemented, uncemented, or hybrid/inverse hybrid.
b
In the period 1994–1999, only Scan resurfacing prostheses were used and they were all cemented. After this, the Scan prostheses were not used and the new resurfacing prostheses were mainly uncemented.
c
Almost exclusively cemented humeral component and uncemented glenoid component.
