Extensor tendon rupture after internal fixation of a distal radius fracture using a dorsally placed AO/ASIF titanium pi plate. Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation.

Extensor tenosynovitis has been reported as a complication of the Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation (AO/ASIF) pi plate. The authors present a case of extensor tendon rupture after internal fixation with a pi plate after one of the screws in the distal limb loosened. This mechanism of extensor tendon rupture has not been reported previously. With appropriate prevention, monitoring, and intervention this complication could have been avoided. Schnur DP, Chang B.
