The purpose of this study was to analyze and report functional and radiological results obtained with the Durom™ Shoulder Cup. From 2004 to 2009, 42 consecutive shoulder resurfacing prostheses were implanted in a cohort of forty patients with morphologically and functionally healthy rotator cuff. Those cases were evaluated preoperatively and postoperatively after an average of 33.5months on the basis of Constant score, ASES score, and X-rays. The Constant score increased from 29.88 points preoperatively to 82.34 after a mean follow-up period of 33.5months. The ASES score went from 30.55 points preoperatively to 76.61. Radiologically we noticed neither radiolucent lines nor any aseptic loosening of the prosthetic cup. In the post-operative X-rays evaluation we found no significant central migration of the humeral head from the first postoperative X-ray. The good functional results observed with a mean follow-up of approximately 3years doubtless resulted from the reduction in implant-placement error, as a result of the resurfacing procedure, and from the normal rotator cuff function. This technique facilitates surgical reconstruction of the anatomical and biomechanical conditions required for physiological function of the shoulder.
