Concept
The Dynamic Distal Radius External Fixator applies the distraction force perpendicular to distal radius articular surface, enhancing ligamentotaxis results.
The Dynamic Distal Radius External Fixator features adjustable joints, enabling the surgeon to adjust the traction force axis perpendicular to the articular surface.
A key feature of dynamic distal radius external fixators is their capacity for "gradual distraction" facilitated by a distractor nut. Additionally, these fixators offer the advantage of inserting Schanz pins at any desired distance or direction, owing to the independent clamp system located in the proximal or distal portion of the fixator.
Ligamentotaxis serves as the primary mechanism for achieving closed reduction of distal radius fractures, with optimal reduction attained when the traction axis is ulnarly and volarly deviated perpendicular to the distal radius articular surface. Volar tilt and radial inclination constitute two critical radiological parameters governing the alignment of the distal radius articular surface
Distal radius fractures represent the most prevalent fracture type encountered in emergency settings. External fixation stands out as one of the optimal treatment modalities for managing distal radius fractures, particularly beneficial in cases involving articular or metaphyseal comminution.
Adjustment of the articular components of the external fixator is conducted in accordance with radiological parameters of the unaffected side.
