Arthroscopically Assisted Eaton–Littler Trapeziometacarpal Ligamentoplasty

Background  Eaton-Littler ligamentoplasty has proven its efficacy in the treatment of trapeziometacarpal (TMC) instability. Description of Technique  In this article, we describe the arthroscopically assisted Eaton-Littler ligamentoplasty through two clinical cases. Patients and Methods  Arthroscopy is used to accurately place the metacarpal bone tunnel and pass the slip of flexor carpi radialis tendon in the latter. This procedure avoids soft-tissue dissection and could improve the outcome of this well-known surgery. Results  The two clinical cases showed good short-term outcome with a decrease of pain and good function. Conclusions  Arthroscopy to assist Eaton-Littler TMC ligamentoplasty is technically feasible, allowing a less invasive surgery. A larger prospective controlled study with a longer term outcome is mandatory to assess the real advantages of this modified procedure.
