Variation in practitioner-measured x-ray angles in hallux abducto valgus evaluation

Area of Science:

• Orthopedic surgery
• Radiographic analysis
• Podiatry

Background:

• Preoperative hallux abducto valgus (HAV) X-rays are crucial for surgical planning.
• Angular measurements guide deformity assessment and procedure selection.
• Inter-physician reliability of these measurements is largely untested.

Purpose of the Study:

• To evaluate the variability of five key angular measurements in preoperative hallux abducto valgus (HAV) X-rays.
• To assess the consistency of these measurements among podiatrists with diverse experience levels.
• To determine if preoperative radiographic measurements accurately reflect the degree of first metatarsophalangeal joint pathology.

Main Methods:

• A group of podiatrists with varying experience measured five standard angles on preoperative hallux abducto valgus (HAV) X-rays.
• Data was collected to analyze the variations in measurements between different practitioners.
• Statistical analysis was performed to quantify inter-observer reliability.

Main Results:

• Significant variations in the measured angles were observed among the participating podiatrists.
• The degree of variability suggests inconsistency in interpreting preoperative radiographic measurements.
• These findings indicate potential inaccuracies in assessing the severity of the deformity.

Conclusions:

• Preoperative radiographic measurements for hallux abducto valgus (HAV) may not provide a reliable or accurate assessment of the first metatarsophalangeal joint pathology.
• Variability in measurements highlights challenges in standardizing surgical planning based on current radiographic techniques.
• Further research is needed to improve the reliability of radiographic assessments in diagnosing and planning treatment for HAV.
