Patients who want to avoid the potential risks and limitations of a prosthetic glenoid can opt for the ream-and-run procedure (RnR).
This is an example of postoperative function for a 57-year-old man five years after he had his operation.
One of the most important centers for the advancement of the ream & run procedure is Warren Alpert Medical School of Brown University. Last year these surgeons published Early outcome of humeral head replacement with glenoid reaming arthroplasty (Ream and Run) for treatment of advanced glenohumeral osteoarthritis evaluating their short- and midterm outcomes for this procedure in 49 shoulders (mean age 60 years, 43 males) with minimum 2-year follow-up (mean 4.6 years). Thirteen (26.5%) had previously undergone non-arthroplasty shoulder surgery. Most of the shoulders (61%) had type B glenoids.
To preserve as much subchondral bone, the glenoid was ground to a radius of curvature that was between 4-6 mm and that of the selected component of the humeral.
Assisted motion began immediately, active-assisted mobility started after six weeks, and strengthening started at 12 weeks following surgery.
