Advanced Three-Dimensional Assessment and Planning for Hallux Valgus.

Area of Science:

• Orthopedics
• Radiology
• Biomechanical Engineering

Background:

• Conventional 2D radiographs have limitations in fully characterizing complex hallux valgus deformities.
• Understanding foot and ankle biomechanics in a weightbearing state is crucial for accurate diagnosis.

Purpose of the Study:

• To explore the utility of advanced three-dimensional (3D) evaluation of hallux valgus using weightbearing computed tomography (WBCT).
• To highlight the role of WBCT in assessing bone alignment and joint stability in hallux valgus.
• To discuss the impact of emerging technologies on hallux valgus management.

Main Methods:

• Utilizing weightbearing computed tomography (WBCT) for advanced 3D imaging of hallux valgus.
• Analyzing bone alignment, joint stability, and foot biomechanics under physiological load.
• Integrating semiautomatic and artificial intelligence (AI) tools for enhanced deformity assessment.

Main Results:

• WBCT provides superior, detailed insights into hallux valgus compared to conventional radiography.
• First ray hypermobility and intrinsic metatarsal rotation are significant factors in hallux valgus, identifiable with WBCT.
• AI-assisted WBCT enhances precision in deformity assessment.

Conclusions:

• Weightbearing computed tomography represents a significant advancement in evaluating hallux valgus.
• Precise 3D assessment using WBCT facilitates personalized surgical planning and improves patient outcomes.
• The integration of AI promises more effective and tailored hallux valgus management strategies.
