BACKGROUND: Shoulder arthroplasty surgery has undergone remarkable progress. New concepts like reverse and stemless shoulder prostheses have been widely used. The Total Evolutive Shoulder System (TESS) is a new innovative system that provides the surgeon with different prosthetic versions. The purpose of the present study was to evaluate our short-term results and complications of the TESS. PATIENTS AND METHODS: 56 consecutive patients were operated with one of the two versions of TESS (anatomical or reverse) between October 2007 and December 2009. Preoperative and postoperative evaluation of the function and life quality was achieved by the Quick Disability of the Arm, Shoulder and Hand (DASH) index and EQ-5D self-report questionnaire, respectively. Radiographic follow-up by anteroposterior, axillary and lateral views was done. The anterosuperior approach was used in all cases. We compared the outcome in fracture patients with other categories. RESULTS: 49 patients were available for 9-24 months (mean 14) clinical and radiographic postoperative follow-up. The mean of quick DASH improved from 56 preoperatively to 34 postoperatively (p < 0.001) and EQ-5D from 0.36 preoperatively to 0.73 postoperatively (p < 0.001). The complications were few and we had no radiolucencies or scapular notching during the study period. Fracture patients did worse compared to other categories. CONCLUSIONS: TESS prosthesis showed promising short-term results with few complications. The reverse version could be implanted without stem if initial stability was adequate. Long-term follow-up is required to confirm the results of this innovative system in the long run.
