Yen S Chiang, Shih H Chen, Keng C Liu, Chang C Yang, Jui Teng Chien

Background: Implant loosening and periprosthetic fracture nonunion is the most challenging complications of total elbow arthroplasty. There is limited literature on how to treat these conditions. This study describes the surgical technique used in an innovative nail-stem construct and evaluates patient outcomes following this salvaging method.

Case presentation: We present four cases in this study between 2018 and 2019. All four patients (average age 78.7 years) achieved an optimal range of motion and secure stability with a painless elbow at the final follow-up.

Conclusion: Our innovative, low cost nail-stem construct procedure is a feasible alternative for revision total elbow arthroplasty in patients with implant loosening, periprosthetic humeral fractures, and recalcitrant nonunion.
