The use of dynamic radiographs in trapeziometacarpal joint arthrodesis for accurate range of motion evaluation

These findings on the amount of hypermobility of MP joint after TM joint arthrodesis are valuable information for optimal postoperative rehabilitation protocol. To achieve good range of motion of thumb abduction and adduction following TM joint arthrodesis, emphasis must be placed in obtaining maximum potential motion of STT joint rather than hypermobility of MP joint.
