Elbow posterolateral rotatory instability (PLRI) was first described by O'Driscoll et al., in 1991 [1]. The condition is defined as an insufficiency of the lateral collateral ligamentous complex and is reported as the most frequent type of chronic elbow instability [2]. Recalcitrant cases of elbow posterolateral rotatory instability (PLRI) can be challenging. The treatment consists of reconstructing the lateral ulnar collateral ligament (LUCL) as a primary stabilizer and is technically demanding [3,4]. However, the most frequently reported complication after LUCL reconstruction is recurrent instability – up to 25 % [3,5,6]. This puts primary LUCL reconstruction into question, it was thus hypothesized that enhancing the secondary stabilizers will provide successful results with a lower rate of recurrent instability in comparison to techniques with primary reconstruction only.

This study aimed to demonstrate a novel surgical technique for LUCL reconstruction in patients with chronic PLRI.
