Long-term retrospective review of the GSB III semiconstrained 'sloppy hinge' total elbow prosthesis. It reports pain, motion, survivorship, and complications at a mean 13.5 years in rheumatoid and post-traumatic patients. The goal was to define durability of a linked elbow implant followed beyond ten years.
When you counsel a rheumatoid patient facing total elbow arthroplasty, this paper gives you the durability numbers: roughly 88% survivorship at 13.5 years with reliable pain relief in over 90%.
Understand the design logic. The GSB III is a linked 'sloppy hinge' that allows ~5° of varus/valgus and rotation. That play unloads the bone-cement interface, which is why its 4.6% loosening rate undercut the 17.2% seen elsewhere. The condylar flanges matter clinically: they distribute stress across the distal humerus, so preserve or reconstruct both condyles when you can.
Know the complication pattern. Disassembly (13.8%) came from malposition off the center of rotation and triceps insufficiency, and every deep infection followed a revision. Reserve caution for the young, active post-traumatic patient, who loads the implant hardest and fares worst.
