Extra-articular distal radius fracture malunion correction
Fracture Management
- Cases often involve distal radius fractures and complications post-conservative treatment.
- Frequent challenges: infection, incongruency in the distal radius, especially on the ulnar side.
X-Ray Analysis
- Important for assessing total angulation and inclination of the radial articular surface.
- Example: a total angulation of degrees.
Surgical Approach Historical Context
- Discussion on dorsal angulation correction methods (i.e., loading the dorsal aspect).
- Use of K-wires and small fixators for stabilization.
- Palmar approach advocated for correcting malangulation with predetermined angles (e.g., fixing a plate at degrees for a degree dorsal angulation).
Common Techniques and Tools
- Use of specific plates (Klas Martin’s design) has been standard in numerous cases.
- Importance of correct osteotomy level to avoid complications (sigmoid notch considerations).
3D Planning and Surgical Precision
- Optimal for accurately addressing axial, rotational, and longitudinal deformities.
- Patient-specific implants can assist in precise corrections.
Case Study Analysis
- Examples of individualized cases.
- Importance of assessing previous fracture sites and correcting deformities with direct bone contact rather than grafting when stable.
Complex Joint Relationships
- Importance of assessing congruency across all joints involved in motion and stability (i.e., proximal, shaft, and distal regions).
Planning for Growth
- Considerations for surgical planning in younger patients due to ongoing growth.
Conclusion on Techniques
- While freehand techniques are viable, 3D planning is recommended for complicated cases to ensure accuracy of corrections.
- Experience is key when opting for freehand approaches.
- 3D techniques yield predictable results, particularly in addressing cortical deformities.
