[Distal radius fracture. Correlation between radiological and functional results]

Area of Science:

• Orthopedic surgery
• Radiology
• Biomechanics

Background:

• Distal radius fractures are common injuries.
• Assessing functional outcomes is crucial for patient recovery.
• Radiological parameters may influence treatment success.

Purpose of the Study:

• To determine the impact of radiological parameters on functional outcomes in distal radius fractures.
• To quantify the tolerance for deformity after distal radius fracture.

Main Methods:

• 344 patients with isolated distal radius fractures were analyzed.
• 211 patients underwent functional assessment using modified Gartland and Werley score.
• A custom score evaluated radiological parameters' influence on outcomes.

Main Results:

• Articular step-off >1 mm (13% of patients) correlated with a 24% reduction in range of motion.
• Radial shortening >3 mm (n=12) led to a 21% reduction in pronation/supination.
• Radial tilt and palmar inclination showed no direct influence on function; however, K-wire pinning with initial palmar inclination < -15° resulted in significant secondary loss.

Conclusions:

• Radial shortening and articular step-off are key radiological factors affecting functional outcomes.
• These findings aid in predicting recovery and guiding treatment for distal radius fractures.
