“…Contrary to what we found in this study, two studies conducted by Heineman et al (11,12) demonstrated a good correlation between HVA measurements from MRI and those from radiography during weight bearing. Despite the differences, both studies established that the objective HVA measurement can be incorporated into clinical practice for the diagnosis of hallux valgus.…”

Objective: To assess the accuracy of magnetic resonance imaging (MRI) for the diagnosis of hallux valgus using radiography during weight bearing as the gold standard. Materials and Methods: This was a retrospective analysis of all patients undergoing MRI of the foot and radiography of the foot during weight bearing at our institution between January and June of 2015. The hallux valgus angle (HVA) was measured on MRI and radiography. The Wilcoxon signed-rank test and simple linear regression were used in order to compare measurements. Patients were divided into two groups according to the HVA determined on radiography: > 15° (hallux valgus) and ≤ 15° (control). Qualitative and quantitative assessments of MRI scans were performed. For quantitative assessment, receiver operating characteristic curves were used in order to determine the HVA cutoff with the highest accuracy. Results: A total of 66 MRI scans were included, 22 in the hallux valgus group and 44 in the control group. Wilcoxon signed-rank tests indicated a significant difference between the radiography and MRI measurements. Simple linear regression showed a nonlinear relationship between the measurements and values did not present a strong correlation. In comparison with the radiography measurements, MRI with an HVA cutoff of 16.4° exhibited the highest accuracy (86%). The accuracy of the subjective (qualitative) assessment was inferior to the objective assessment (measurement of the HVA). Conclusion: Hallux valgus can be diagnosed by measuring the HVA on MRI, satisfactory accuracy being achieved with an HVA cutoff of 16.4°.

“…The data presented by Helito et al (9) support the findings of Heineman et al (1) who demonstrated excellent interobserver agreement for the HVA and for the IMA on radiographs obtained during weight bearing and on MRI. Over the range of values that they tested, MRI was considered a viable imaging modality for diagnosing and assessing the severity of hallux valgus.…”

“…Hallux valgus is a common foot deformity, affecting approximately 36% of adults over the age of 65, mainly occurring among women (1,2) . This condition is defined as medial deviation of the first metatarsal bone, lateral deviation of the hallux, and a prominent first metatarsal head.…”

“…This condition is defined as medial deviation of the first metatarsal bone, lateral deviation of the hallux, and a prominent first metatarsal head. Hallux valgus can be caused by instability and insufficiency from the distal phalanx to the talonavicular joint, anywhere along the first ray (1,3) . The most important static stabilizers on the medial side of the hallux are the articular capsule, collateral ligaments, and medial sesamoid ligament.…”

“…The point method had been shown by one author to be more reliable than the traditional midline method (17). However, recent studies have shown that traditional and point methods for HVA and IMA measurements are equally reliable on both radiographs and MRI with higher overall reliability for HVA (32,33).

Hallux valgus is a common condition estimated to affect as many as 23% of adults. The condition is associated with a variety of debilitating symptoms leading to significant morbidity and quality of life issues. Proper evaluation of this deformity and the timely management of its symptoms can improve hallux valgus-related symptomatology and quality of life. The most commonly used and readily reproduced measurements for assessing hallux valgus are the inter-metatarsal angle and the hallux valgus angle. These angles are helpful for choosing and planning surgical intervention for patients who fail initial conservative measures with distal osteotomies reserved for mild or moderate hallux valgus and proximal osteotomies indicated for more moderate to severe deformities. After reading this review article, readers will gain knowledge of the etiopathogenesis of hallux valgus, measurement parameters, and treatment strategies with representative case examples.
