Abstract
PURPOSE: Total shoulder (TSA) is commonly used to treat arthritic shoulders with intact rotator cuffs; however, some patients choose a ream and run (RnR) to avoid the potential risks and limitations of a prosthetic glenoid component. Little is known about how patients selecting each of these two procedures compare and contrast. METHODS: We analyzed the patient characteristics, shoulder characteristics, and two year clinical outcomes of 544 patients having RnR or TSA at the same institution during the same six year period. RESULTS: Patients selecting the RnR were more likely to be male (92.0% vs. 47.0%), younger (58 ± 9 vs. 67 ± 10 years), married (83.2% vs. 66.8%), from outside of our state (51.7% vs. 21.7%), commercially insured (59.1% vs. 25.2%), and to have type B2 glenoids (46.0% vs. 27.8%) as well as greater glenoid retroversion (19 ± 11 vs. 15 ± 11 degrees) (p < .001). The average two year SST score for the RnRs was 10.0 ± 2.6 vs. 9.5 ± 2.7 for the TSAs. The percent of maximum possible improvement (%MPI) for the RnRs averaged 72 ± 39% vs. 73 ± 29% for the TSAs. Patients with work-related shoulder problems had lower two year SSTs and lower %MPIs. Younger patients having TSAs did less well than older patients. Female patients having RnRs did less well than those having TSAs (p < 0.001). CONCLUSIONS: This investigation highlights important characteristics of patients selecting the RnR and the TSA for glenohumeral arthritis. Excellent outcomes can be achieved for appropriately selected patients having either procedure.
