Summary

Most Galeazzi fractures can be treated adequately with open reduction and internal fixation (ORIF) of the radius alone, but some will remain unstable at the DRUJ and require repair of the TFCC.The purpose of this anatomical and biomechanical study was to define and measure DRUJ dislocation, displacement and instability associated with the sequential sectioning of the different bands in the interosseous membrane (IOM) and TFCC in the simulation of a Galeazzi fracture.

Detailed description

Instability of the DRUJ is a common clinical problem associated with Galeazzi fracture. Stability of the DRUJ is primarily provided by both the bony anatomy of the sigmoid notch of the radius and ulnar head and the soft tissues surrounding the joint. The interosseous membrane plays an important role in DRUJ stability but the TFCC is the major soft tissue stabilizer of the DRUJ. The Central Band works as a restraint on the radius from proximal migration in cooperation with the radial head and the TFCC and also works as a load transmitter between the radius and ulnar to redistribute load. Some investigators suggested that the distal membranous portion and DOB stabilizes the DRUJ when TFCC is disrupted. Watanabe et al. (2005) insisted on the importance of DOB, which constrained volar and dorsal instability of the radius at the DRUJ in all forearm rotation positions. The purpose of this anatomical and biomechanical study was to define and measure DRUJ dislocation in the simulation of a Galeazzi fracture.
