Study Notes
Extra-Articular Distal Radial Fracture
- 20-year-old male patient with dorsal displacement extra-articular distal radial fracture
- CT images indicate extra-articular fracture with dorsal Comminution
Surgical Approach
- Approach: Volar Henry approach through the flexor carpi radialis
- Flexor sheath opened
- Pronator quadratus dissected and reflected to expose fracture
Reduction Techniques
- Manual reduction and preliminary fixation with K-wires
- Reduction with plate
Manual Reduction and K-wire Fixation
- Plate applied to bone - distal end ending at the watershed zone of the distal radius
- Screw inserted through oblong hole in the proximal radial fragment
- Intraoperative imaging used to check plate position before fully tightening screw
Plate Reduction
- Plate applied to distal fragment - distal end ending at the watershed zone of the distal radius
- K-wire inserted through screw hole parallel to the articular surface as close to the subchondral bone as possible
- Plate angle to radial shaft should equal the angle of displacement
- Image intensification used to confirm position
- Initial screw inserted in most ulnar screw hole
- Screw position confirmed with lateral view under image intensification at 20° to the true lateral to visualize the joint surface.
- At least 2 other distal locking head screws inserted
- Plate brought onto the shaft and held with a clamp
- Check radiographs obtained and distal fragment position adjusted if necessary by moving plate

Description
This quiz covers the surgical management of a dorsal displacement extra-articular distal radial fracture, including techniques such as the Volar Henry approach, manual reduction, and K-wire fixation. It also discusses intraoperative imaging for verifying plate position and reduction strategies. Test your knowledge of orthopedic surgical procedures and their implementation.
