[Long-term results of the total trapezio-metacarpal prosthesis in osteoarthritis of the thumb].
The author reviewed 13 of 14 trapeziometacarpal prostheses inserted more than twelve years ago. All operated patients had non traumatic arthrosis. The long time results seem to be good in spite of a high level of loosening. Combined metacarpophalangeal arthrodesis dived to a fast loosening of the metacarpal device then shortening of the whole column of the thumb. The posture in hyperextension of the metacarpophalangeal joint was the main consequence and phalangeal joint was the main consequence and finally led to the loosening of the trapezial cup. The author considers that the modification of the metacarpal device will protect the metacarpophalangeal stability then the trapezial cup against the loosening.
