Abstract

Chronic posterolateral rotatory instability (PLRI) of the elbow is the result of an insufficiency of the lateral collateral ligament (LCL). Lateral ulnar collateral ligament (LUCL) reconstruction represents a well-established treatment method for PLRI. However, recurrent instability remains a problem. The goal of this in-vitro study was to evaluate the posterolateral rotatory stability of the intact elbow, after sectioning of the LCL and after LUCL reconstruction with a triceps tendon autograft and double BicepsButton(TM) fixation. Posterolateral rotatory stability of 6 fresh-frozen elbow specimens at a torque of 3 Nm was analyzed at 0, 45, 90 and 120A degrees of flexion for the intact LCL, after sectioning of the LCL and after LUCL reconstruction. Moreover, cyclic loading (1000 cycles) of the intact specimens and after LUCL reconstruction was performed. The intact LCL and the LUCL reconstruction provided equal primary stability (0.250 aecurrency sign p aecurrency sign 0.888). Sectioning of the LCL significantly increased PLRI (p < 0.001). The stability of the intact specimens and after LUCL reconstruction did not differ after cyclic loading (p = 0.218). During cyclic loading, posterolateral rotation increased significantly more after LUCL reconstruction (3.2 +/- 0.8A degrees) when compared to the native LCL (2.0 +/- 0.7A degrees, p = 0.020). LUCL reconstruction with BicepsButton(TM) fixation provides comparable stability to the native LCL. Further clinical results are necessary to evaluate whether this technique can decrease the complication rate.
