Short-term results of the reverse Total Evolutive Shoulder System (TESS) in cuff tear arthropathy and Revision Arthroplasty cases
Archives of Orthopaedic and Trauma Surgery, 2015Co-Authors: Lars Victor Von Engelhardt, Michael Manzke, Timm J. Filler, Joerg JeroschAbstract:IntroductionThe aim of this study was to evaluate the clinical and radiological outcome of the Total Evolutive Shoulder System (TESS) in patients with cuff tear arthropathy and patients in need of a Revision Arthroplasty.MethodsIn this sequential study, 67 patients (56 non-stemmed, 11 stemmed) were evaluated after a mean follow-up of 17.5 months. The relative Constant and DASH scores, radiological joint geometry changes, complications and postoperative problems, which are not likely to affect the outcome, were evaluated.ResultsA significant increase was noticed for the relative Constant (11.3 vs. 78.8 %) and DASH scores (73.7 vs. 31.8) without significant differences between both etiology groups. Complication rates were similar to previous studies. An aseptic loosening of the non-stemmed humeral component was not noticed in the cuff tear arthropathy group, whereas one case with a loosening was noticed in the Revision Arthroplasty group. With nine cases (13.4 %), scapular notching rates were very low. On average, the acromiohumeral distance increased by 17 mm and the humeral offset by 13.9 mm; the height of the center of rotation decreased by 4.6 mm and the lateral glenohumeral offset by 6.1 mm, p

Primary cementless hip Arthroplasty as a potential risk factor for non-union after long-stem Revision Arthroplasty in periprosthetic femoral fractures
International Orthopaedics, 2015Co-Authors: Sandra Boesmueller, Marc Michel, Marcus Hofbauer, Patrick PlatzerAbstract:PurposeIn case of stem loosening in periprosthetic femoral fractures (PPFF), Revision Arthroplasty should be performed. The first hypothesis of this study was that advanced patient age and female gender shows higher non-union rates. The second hypothesis was that primary cementless Arthroplasty is associated with a higher non-union rate compared to cemented primary hip Arthroplasty.MethodsAll PPFF occurring between January 2000 and June 2010 treated by Revision Arthroplasty were included. Multiple regression analysis was performed to identify independent variables leading to fracture non-union.ResultsEighty one patients (78 % female) met the inclusion criteria. In 20/81 patients (24.7 %) no adequate fracture healing could be determined on radiographs 12 months after Revision surgery. Although age and female gender showed a positive correlation with bony non-union after PPFF as expected, the p-values were not statistically significant. Multiple regression analysis revealed primary cementless prosthesis ( p = 0.001) to be the only independent variable associated with non-union.ConclusionNon-cemented primary prosthesis might be a negative predicting factor for the development of non-union after long-stem Revision Arthroplasty in PPFF. We therefore recommend the thorough debridement of pannus tissue thus inducing bone healing before the implantation of Revision prostheses.

neer award 2005 the grammont reverse shoulder prosthesis results in cuff tear arthritis fracture sequelae and Revision Arthroplasty
Journal of Shoulder and Elbow Surgery, 2006Co-Authors: Pascal Boileau, Duncan Watkinson, Armodios M Hatzidakis, Istvan HovorkaAbstract:This clinical study was performed to analyze the midterm results and potential complications of the reverse prosthesis in different diagonosis. Forty-five consecutive patients with Grammont prosthesis were evaluated clinically and radiographically with a mean follow-up of 40 months (range, 24-72 months). The indication was a massive and irreparable cuff tear associated with arthrosis (CTA) in 21 cases, fracture sequelae (FS) with arthritis in 5 cases, and failure of a Revision Arthroplasty (Revision) in 19 cases. Fourteen complications occurred in 11 patients. 3 dislocations, 3 deep infections (all 3 in the Revision group), 1 case of aseptic humeral loosening, 2 periprosthetic humeral fractures, 1 intraoperative glenoid fracture, 1 wound hematoma, 2 late acromial fractures, and 1 axillary nerve palsy. Of the patients, 10 (22%) required further surgery: 4 reoperations, 4 prosthesis Revisions, and 2 prosthesis removals. Complications were higher in Revision than in CTA (47% vs. 5%). All 3 groups showed a significant increase in active elevation (from 55° preoperatively to 121° postoperatively) and Constant score (from 17 to 58 points) but no significant change in active external rotation (from 7° to 11°) or internal rotation (S1 preoperatively and postoperatively). Of the patients, 78% were satisfied or very satisfied with the result and 67% had no or slight pain. However, the postoperative Constant score, adjusted Constant score, and American Shoulder and Elbow Surgeons shoulder score were all significantly higher in the CTA group with as compared with the Revision group ( P = .01, .004, and .002, respectively). Scapular notching was seen in 24 cases (68%). No glenoid loosening was observed at current follow-up, even when the notch extended beyond the inferior screw (28% of cases). Atrophy of severe fatty infiltration of the teres minor was associated with lower external rotation (15° vs 0°, P = .02) and lower functional results (Constant score of 46 points vs 66 points, P
