[The radio-lunate sagittal index]

Area of Science:

• Orthopedic Surgery
• Radiology
• Anatomy

Background:

• Colles' fractures often involve significant displacement.
• Posterior subluxation of the carpus is a common complication.

Purpose of the Study:

• To introduce a novel radiographic measurement for assessing posterior displacement in Colles' fractures.
• To provide a tool for guiding fracture reduction.

Main Methods:

• Development of a radio-lunate sagittal index.
• Measurement of posterior displacement using the index.

Main Results:

• The radio-lunate sagittal index quantifies posterior carpal displacement.
• The index is applicable to displaced Colles' fractures.

Conclusions:

• The radio-lunate sagittal index is a valuable tool for evaluating displaced Colles' fractures.
• This index should be utilized during fracture reduction to ensure accurate alignment.
