Distal radius fractures are a major part of my practice, and they are not simple injuries. These fractures involve the wrist joint itself, and small technical details during surgery can have a meaningful impact on long-term wrist function, strength, and pain. Treating these injuries well requires a deep understanding of wrist biomechanics and careful attention to surgical construct design.
A recent study published in The Journal of Hand Surgery highlights why surgical technique-specifically screw placement relative to the joint surface-matters so much for patients undergoing operative fixation of complex distal radius fractures.
Why Distal Radius Fractures Require Technical Precision
Distal radius fractures account for a large percentage of adult fractures treated in emergency departments. While many wrist fractures can be managed nonoperatively, others-particularly comminuted intra-articular fractures-require surgical fixation to restore joint alignment and stability.
For these more complex injuries, the goal of surgery is not simply to put the bone back together, but to create a construct that resists collapse as the fracture heals. Loss of alignment after surgery, even by a few millimeters, can alter wrist mechanics and negatively affect long-term outcomes.
What This Study Examined
This study focused on patients with severely comminuted intra-articular distal radius fractures treated with volar locking plates. The researchers analyzed how close the distal screws were placed to the subchondral bone-the strong bone just beneath the joint surface.
They measured the distance from the distal row of screws to the joint surface and tracked whether fractures lost alignment during the early healing period.
The Key Finding Patients Should Understand
The most important takeaway from this research is straightforward.
When the distal screws were placed more than 3 millimeters away from the subchondral bone, patients had nearly four times the odds of losing wrist alignment during healing.
In contrast, when screws were placed close to the joint surface-within 3 millimeters-fractures were significantly more likely to maintain their reduction.
Notably, patient age, baseline bone density, fracture instability, and plate position alone were not associated with loss of alignment. The critical variable was distal screw placement relative to the joint surface.
Why Subchondral Screw Placement Matters
From a biomechanical standpoint, the distal screws act as a raft supporting the joint surface. If those screws are placed too far from the subchondral bone, the articular surface can settle or collapse during healing, even when the plate appears well positioned.
This study reinforces what experienced hand surgeons already understand: precise screw placement is essential to maintaining joint alignment, particularly in high-energy or highly comminuted fractures.
In my practice, I am deliberate about placing distal screws subchondrally to provide a stable construct while still respecting tendon anatomy and minimizing complication risk. Achieving that balance requires experience, training, and attention to detail.
What This Means for Patients in Dawsonville, Braselton, and Duluth
For patients across North Georgia-including Dawsonville, Braselton, and Duluth-this research highlights why surgeon expertise matters when treating wrist fractures that require surgery. Two operations may look similar on the surface, but subtle technical differences can determine whether a fracture holds its alignment during healing.

Distal Radius Fractures Deserve Specialized Care
Not all distal radius fractures need surgery, and not all surgeons approach these injuries the same way. For fractures that do require operative fixation, meticulous technique and thoughtful construct design are essential to achieving the best possible outcome.
This study provides strong clinical evidence supporting careful subchondral screw placement and reinforces the importance of having a hand surgeon who understands the biomechanics behind these decisions.
