Traumatic trapeziometacarpal joint dislocation of the thumb accounts for less than 1% of all hand injuries. This injury is even less common in children. Optimal treatment strategies for this injury are still the subject of debate for both children and adults. We report a case of recurrent posttraumatic trapeziometacarpal joint dislocation in an eight-year-old girl. We believe our case is the fi...

BACKGROUND Arthritis at the trapeziometacarpal joint of the thumb is common. Several surgical options exist showing favorable results. We report the outcomes after interposition of allograft knee meniscus for thumb trapeziometacarpal arthritis. METHODS Twenty-three patients (25 thumbs) had surgery for thumb trapeziometacarpal arthritis using knee meniscal allograft tissue. Eleven thumbs had a...

To measure the motions of the trapeziometacarpal joint of the thumb quantitatively, a roentgenographic method was developed and tested using T-shaped metal markers, a special cassette-holder, and biplane roentgenograms. Two experiments were performed. In the first one, the metal markers were fixed to the trapezium and third metacarpal in ten cadaver specimens, and a fixed spatial relationship b...
