Distal Radius Fracture Subsidence after Nonoperative Treatment.

Area of Science:

• Orthopedics
• Traumatology
• Radiology

Background:

• Distal radius fractures (DRFs) are common injuries.
• Understanding subsidence development in nonoperatively treated DRFs is crucial for patient outcomes.
• Identifying risk factors can guide treatment decisions.

Purpose of the Study:

• To identify risk factors for subsidence development in nonoperatively treated distal radius fractures (DRFs).
• To compare subsidence progression over time with respect to radiographic parameters.

Main Methods:

• Retrospective cohort study of 70 patients with nonoperatively treated DRFs.
• Minimum follow-up of 12 weeks.
• Radiographic measurements included radial height (RH), ulnar variance (UV), volar tilt (VT), and radial inclination (RI).

Main Results:

• Nearly 95% of DRF subsidence occurred within the first 6 weeks.
• Closed reduction was associated with increased subsidence (p=0.0009).
• Comminution and AO fracture type C were significant predictors of subsidence.

Conclusions:

• Most distal radius fracture subsidence manifests within 6 weeks of nonoperative management.
• Closed reduction, fracture comminution, and AO fracture type are key predictors of subsidence.
• Subsidence progression varies based on specific radiographic parameters.
