Management of unstable injuries was revolutionized by the Internal Joint Stabilizer (IJS). When compared to long-term immobilization, transarticular pinning, and hinge external fixation, the IJS results in decreased complications and improved clinical outcomes. Historically, the IJS was applied via a lateral approach; however, this limited intraoperative visualization and, in some cases, resulted in increased operative times. This technical report describes a posterior approach, for IJS application. The posterior approach involves an 8- to 10-cm incision over the posterior elbow through the deep fascia before identifying the olecranon and lateral capitellum, then proceeding with IJS application through manufacturer instructions. The ulnar and radial nerves must be identified as they could be damaged in this approach. Using the posterior approach at our institution, we have noticed a possible decrease in operative times and an increase in intraoperative visualization of the elbow without a subsequent increase in complications.
