چکیده
Background: The purpose of this study was to examine the mid-term functional outcomes, radiographic results,and revision rates of patients treated with the Delta Xtend Reverse Shoulder System for both primary and revisionarthroplasty indications.Methods: A retrospective review was conducted of records for all individuals who underwent a reverse shoulderarthroplasty using the Delta Xtend Reverse Shoulder Prosthesis at a single institution. Radiographic analysis as well aspain and functional measures using the ASES, Quick DASH, SST, SF-12, Penn, SANE, EQ-5D and VAS, and VR-12scores. Patients were evaluated for five-year outcomes.Results: Fifty patients were available for 5-year outcomes. Thirty-three cases were primary arthroplasty cases and17 were revision arthroplasty cases. Postoperative radiographs at five years out from surgery were available for 46patients. The mean AGT overall was 32.6mm: 31.7mm the primary cases and 34.8mm for revision cases. Sirveauxscapular notching was: 65.2% (30/46) at Grade 0, 23.9% (11/46) at Grade 1, and 10.9% (5/46) at Grade 2. Overall,32/46 of stems were in neutral position, 10/46 were in valgus position, and 4/46 were in varus position. There was nosignificant correlation between stem position and scapular notching. The mean outcome scores for all patients at fiveyears were good to excellent. Two revision patients demonstrated loosening of the humeral stem on radiographs. Ninepatients demonstrated calcification of the long head of the triceps tendon.Conclusion: In conclusion, the Delta Xtend Reverse Shoulder System has shown to be a reliable arthroplastysystem for patients with CTA or failed prior arthroplasty. Patients are generally quite functional at five years out fromtheir reverse shoulder arthroplasty using this implant. Radiographic measures used to interpret the status of theimplant demonstrate that AGT is well maintained and scapular notching is minimal for the majority of cases.Level of evidence: IVکلیدواژه ها
