Background The trapeziometacarpal joint (TMCJ) is inherently unstable, relying on ligament restraint to prevent subluxation. Subluxation of the thumb in a dorsoradial direction is often observed in clinical practice, either after acute ligament injury or more commonly with osteoarthritis (OA). This subluxation follows loss of function of trapeziometacarpal ligaments that stabilise this joint, r...

Trapeziometacarpal joint is important concerning thumb function. However, this deep joint is clinically difficult to assess. The purpose of our study is to evaluate the range-of-motion of trapeziometacarpal joint with an in vivo kinematics protocol. One hundred and fifteen hands have been studied in 73 healthy subjects, (twenty-two females and fifty-one males). The mean age was 23.1 years old. ...

Adverse reactions to metal-on-metal (MoM) prostheses are well known from total hip joint resurfacing arthroplasty with elevated serum chrome or cobalt, pain and pseudo tumor formation. It may, however, also be seen after total joint replacement of the trapeziometacarpal joint using MoM articulation, and we present two cases of failure of MoM prostheses due to elevated metal-serum levels in one ...

We present the case of a 71-year-old, left-handed woman with left thumb carpometacarpal (CMC) joint arthritis. The patient had no pain and could use the hand actively in daily life with a new option of surgical treatment, a vascularized pedicled third CMC joint transfer to the thumb CMC joint.
