Correction of acquired glenoid bone loss in osteoarthritis with a standard versus an augmented glenoid component.

摘要: Background The magnitude and anatomic consequences of pathologic acquired glenoid retroversion posterior bone loss that can be surgically corrected with a standard versus an augmented component have not been studied extensively in surgical patient population. Materials methods Twenty-nine patients glenohumeral osteoarthritis, loss, increased were by use three-dimensional computer simulation. For each case, amount medialization was measured as the linear distance from lateral aspect vault model to center articular implant surface. Simulation placement at 0° or 6° performed having uniform thickness asymmetric component. Results An seen glenoid, 8.3 ± 4.1 mm, compared 3.8 3.3 mm ( P R 2 = 0.825) −0.68) implant. There ability correct greater amounts version less step anchor peg glenoid. Discussion Correction moderate severe reaming cannot always done component, if it is done, will result joint line. Use allow complete correction minimize effect medialization.
