Analysis of Trapeziometacarpal Joint Mechanics During Spanning and Nonspanning Fixation for Thumb Metacarpal Distraction Lengthening
The TMj spanning fixation during metacarpal distraction decreased joint space narrowing and TMj subluxation. Despite finding reduced contact area and fewer overloaded sensels in group 1, these parameters did not reach statistical significance. Spanning TMj fixation may mitigate TMj instability during metacarpal distraction osteogenesis.
