Trapeziometacarpal instability treated with modified Brunelli ligamentoplasty

Seventeen cases of instability of the trapeziometacarpal joint were treated surgically using either the original Brunelli technique or one of two modifications. Six patients achieved very good, nine achieved good and two achieved poor results. The results of the three surgical techniques were similar and we recommend the use of the palmaris longus tendon for the ligament reconstruction, as it is the easiest to perform.
