Various Diagnostic and Treatment Pitfalls of Combined Fracture Dislocations of Trapezoid and Multiple Carpometacarpal Joints.

We report a rare case of combined fracture dislocations of the trapezoid and multiple carpometacarpal joints that became chronic due to inappropriate treatments. Although an acceptable clinical result was obtained with limited intercarpal fusion, correct diagnosis and initial treatments including anatomical reduction and fixation for obtaining a good clinical result, are important for complex trapezoid injury.
