Three-dimensional dynamic external fixation of distal radial fractures. A prospective study.
This prospective study describes the experience with a new dynamic external fixator which provides three degrees of freedom, while the centre of rotation of all these movements is located in the wrist. 44 patients with unstable fractures of the distal radius were included. During the period of dynamisation, with a median flexion of 30 degrees, extension of 18 degrees, radial deviation of 0 degree and ulnar deviation of 20 degrees the range of motion needed to perform activities of daily living was approached. In spite of early mobilisation reduction was maintained. The radiological result was excellent or good in 82% of the patients and the functional result was excellent or good in 92% of the cases. Pin track infections were noted rather frequently, possibly related to the interaction between the soft tissues and the fixator pins. Based on the experiences of the study the device needs further improvement.
