Volar Cortical Integrity in Non-Operatively Treated Adult Distal Radius Fractures

Area of Science:

• Orthopedic Surgery
• Traumatology
• Radiology

Background:

• Distal radius fractures are common injuries.
• Non-surgical management is often preferred for certain fracture types.
• Predictors of reduction stability are crucial for treatment success.

Purpose of the Study:

• To validate volar cortical integrity (VCI) as a predictor of reduction maintenance in non-surgically treated distal radius fractures.
• To identify other predictors of instability.
• To test the hypothesis that VCI does not affect reduction maintenance.

Main Methods:

• Retrospective review of 112 distal radius fractures treated non-surgically.
• Classification into maintenance of reduction (MOR) or loss of reduction (LOR) groups.
• Bivariate analysis and stepwise logistic regression for predictor identification.

Main Results:

• VCI was significantly different between MOR (80.6%) and LOR (59.2%) groups.
• Post-reduction radial height and VCI were significant predictors in logistic regression.
• Combined VCI and radial height ≥ ulnar neutral predicted 67.8% MOR.

Conclusions:

• Volar cortical integrity is a key predictor for successful non-operative management of distal radius fractures.
• The combination of VCI and adequate radial height enhances prediction of reduction stability.
• These findings support the use of VCI assessment in treatment planning.
