SummarySummary
Reconstruction of the distal humerus with a cemented Reconstruction of the distal humerus with a cemented modular segmental distal humerus / constrained total elbow modular segmental distal humerus / constrained total elbow prosthesis is a safe and reliable method for reconstruction prosthesis is a safe and reliable method for reconstruction following radical resection of selected tumors for palliation orfollowing radical resection of selected tumors for palliation orcurecureFunction is optimized with soft tissue reconstruction and Function is optimized with soft tissue reconstruction and multiple muscle rotation flapsmultiple muscle rotation flapsIt is an acceptable alternative to an above elbow amputation It is an acceptable alternative to an above elbow amputation or shoulder disarticulation or shoulder disarticulation Pain relief is reliable and a functional hand and elbow can be Pain relief is reliable and a functional hand and elbow can be restoredrestoredComplications can be minimized with careful attention to Complications can be minimized with careful attention to neurovascular dissection and soft tissue reconstructionneurovascular dissection and soft tissue reconstructionThe survival of the prosthesis awaits long term resultsThe survival of the prosthesis awaits long term results
