2. The treatment protocol of distal radius fractures relies on a decision scheme developped by Fernandez and Wolfe (21). We favored percutaneous stabilisation over open reduction and internal fixation. No significant clinical difference was noted between those two techniques in unstable fractures (22). The surgical procedure is conducted under brachial plexus anesthesia.For type I and III (4), the fracture is reduced manually with image intensifier control. One or two Kirshner wires (1.5mm) are directed from the tip of the radial styloid dorsally to the first extensor compartment at an angle of approximately 45 degrees to cross the fracture and enter the dorsoulnar cortex of the radius proximally to the fracture. These wires are placed using a power drill. An additional wire is placed into the fracture fragment, inserted into the dorsoulnar corner of the radius between the fourth and fifth extensor compartments and directed from dorsoulnarly towards palmar radially in a distal to proximal direction.6 The tips of the wires are bent and left just outside the skin, if necessary resorbable sutures (Vicryl 3/0) are used. For type III fractures (4), an external fixator bridging the joint completes usually the procedure. The criteria for reduction3 are an ulnar inclination of 22°, a palmar inclination of 11°, neutral ulnar variance and radial width (distance from the most lateral tip of the radial styloid process to the longitudinal axis through the center of the radius on an AP film). A radioscopic image of the contralateral wrist is taken in the operating room to serve as control, in the same prosupination conditions, to be standardized in the radiology department(19,20). The angles are measured preoperatively with an appropriate software (OEC radioscopy ) and controlled postoperatively with the same radioscopy software.
