Clinical usage and influence of radiographs in the assessment of hallux valgus.

It has been assumed that radiographs are consistently used in the preoperative evaluation of hallux valgus; however, little information is available to support this assumption. To investigate the frequency of use and clinical utility of radiographs in the assessment of hallux valgus, an online survey was completed by 28 podiatrists in UK departments of podiatric surgery. Radiographs were used in the assessment of hallux valgus in all departments.

Examining the validity of selected measures of foot type: a preliminary study.

The rationale that subtalar joint position, reflected by calcaneal alignment, determines foot morphology was used to formulate an approach to examination of the validity of three measures of "foot type": the Staheli Arch Index, the Chippaux-Smirak Index, and navicular height. Each measure was calculated in five positions, progressively inverting from a reference position of maximal comfortable eversion. Pearson product moment correlations (Staheli Arch Index: r = 0.
