Shoulder Replacement Improves Function and ComfortThis study reports the results of 71 shoulder joint replacements. All were done by one surgeon. The goal was to find factors present before the operation that are linked with positive results after the operation. If such factors can be found, then surgeons can help patients make better decisions about surgery.
The surgeon used a humeral head implant in all the shoulder replacements. A stem was also inserted into the upper arm bone. The patient's socket (glenoid) wasn't changed. This operation is called a hemiarthroplasty. The same surgery was used for each shoulder. Follow-up rehab was also the same for each patient.
Comfort and function were the two main measures of success. Here's what the researchers found:
The authors conclude that it is possible to use patient information about before shoulder hemiarthroplasty to help ensure a good outcome.
