Arthroscopically Assisted Eaton-Littler Trapeziometacarpal Ligamentoplasty.

 Eaton-Littler ligamentoplasty has proven its efficacy in the treatment of trapeziometacarpal (TMC) instability.  In this article, we describe the arthroscopically assisted Eaton-Littler ligamentoplasty through two clinical cases.  Arthroscopy is used to accurately place the metacarpal bone tunnel and pass the slip of flexor carpi radialis tendon in the latter.

Joint contact areas after radial head arthroplasty: a comparative study of 3 prostheses.

Background: Contact stresses of radial head prostheses remain a concern, potentially leading to early capitellar cartilage wear and erosion. In particular, point contact or edge loading could have a detrimental effect. The purpose of this study was to compare 3 different types of radial head prostheses in terms of joint contact areas with each other and with the native situation.
