Open Volar STT Ligament Reconstruction to Augment the Mathoulin's Arthroscopic Dorsal Capsuloligamentous Reconstruction: Technique Description and Case Reports.

 The results of Mathoulin's arthroscopic dorsal capsuloligamentous reconstruction (ADCLR) are excellent in many patients with scapholunate instability, though less consistently good in higher grade instabilities. The purpose of this article is to describe a novel technique of volar scaphotrapeziotrapezoid (STT) reconstruction which may be used to augment rotational control of the scaphoid, in conjunction with the ADCLR, for use in European Wrist Arthroscopy Society (EWAS) grade IV/V instabilities.  Following completion of ADCLR, the STT joint is approached through the flexor carpi radialis sheath.
