Aseptic loosening, polyethylene wear, and mechanical failure have limited the use of total elbow arthroplasty (TEA) in physically demanding patients. Newer implant designs been introduced to improve performance. The purpose this study was report results obtained after implantation Nexel TEA.Over a 3-year period, 2 surgeons implanted 35 consecutive primary TEAs. average patient age 65 years, standard TEA indications were utilized. Elbows evaluated for pain, motion, Mayo Elbow Performance Score, complications, reoperations.Twelve elbows underwent revision surgery with removal either part or all components at an 2.2 years. All surgeries performed our institution revealed gross loosening component(s). Metallic debris periprosthetic fractures present 45% 50% cases, respectively. Radiographic evaluation existing humeral component 4 elbows, Overall, 17 (50%) reoperation, 20 (60%) sustained least 1 postoperative complication.Primary associated unacceptably high rate early fracture, reoperation. We hypothesize that unexpected could be explained by both utilization titanium-on-polyethylene bearing surface more posterior center rotation causing premature anterior impingement flexion leading bonding interface, secondary titanium particle shedding, osteolysis.
