“…Lee et al [14] demonstrated that fibular overgrowth is present in achondroplastic children between 8 and 11 years of age, which leads to limitation of eversion of the hindfoot. Furthermore, the mean values of tibiotalar angle and talocalcaneal angle in our patients were less than those in the literature [4] (p \ 0.001). That the mean tibiotalar angle value was negative indicated the varus alignment of the ankle.…”

“…We therefore investigated the inter-and intraobserver reliabilities of radiographic measurements and compared mean values of our results with age-matched literature-based normative values to determine which measurement should be considered preferentially in analysis of foot and ankle alignment in children with ACH. As a result, eight of 10 radiographic measurements had excellent both inter-and intraobserver reliabilities; all 10 values had significant differences from age-matched normative values [4].…”

“…During the consensus-building session, measurement techniques and radiographic landmarks were reviewed and clarified with five pediatric orthopaedic surgeons (HRS, QLK, KWP, YJJ, JX) with orthopaedic experience of 33, 22, 10, 4, and 3 years, respectively [4]. We accessed the interobserver reliability by comparing the measurements of the 10 angles or ratios for 40 feet among three examiners (KWP, YJJ, JX).…”

Background Radiographic measurements are typically used in achondroplasia (ACH) during correction of lower limb alignment. However, reliabilities for the measurements on weightbearing radiographs of the foot and ankle in patients with ACH have not been described, and the differences between the ACH population and subjects without ACH likewise have not been well characterized; these issues limit the use of studies on this subject. Questions/purposes We proposed (1) to measure the inter-and intraobserver reliability of a number of radiographic measures of ankle and foot alignment in an achondroplastic cohort of patients; and (2) to compare our radiographic measurement values with age-matched literature-based normative values. Methods Ten radiographic measurements were applied to foot and ankle radiographs of 20 children (40 feet) with ACH (mean age, 10 years; range, 8-16 years). Interobserver and intraobserver reliabilities of these radiographic measurement methods were obtained and expressed by intraclass correlation coefficients (ICCs). The mean values were calculated and compared with the literature-based values. Results The interobserver reliability was excellent for eight measurements with ICCs ranging from 0.801 to 0.962, except for lateral talo-first metatarsal angle and mediolateral column ratio, which were much lower. The intraobserver reliability was excellent for all 10 radiographic measurements with ICCs ranging from 0.812 to 0.998. Compared with existing literature-based values, all 10 measurements had a significant difference (p \ 0.01). Conclusions We suggest tibiotalar angle, calcaneal pitch angle, tibiocalcaneal angle, talocalcaneal angle, naviculocuboid overlap, talonavicular coverage angle, metatarsal stacking angle, and AP talo-first metatarsal angle with excellent interobserver and intraobserver reliabilities should be considered preferentially in analysis of foot and ankle alignment in children with ACH.

Effect of natural full weight‐bearing during standing on the rotation of the first metatarsal bone

et al. 2019

To evaluate the rotational change in the first metatarsal bone (1MT) of the foot during natural standing using an upright computed tomography (CT) scanner with 320‐detector rows. A total of 52 feet of 28 asymptomatic subjects (aged 23–39 years) were evaluated in the natural standing position with or without weight‐bearing. A foot pressure plate was used to determine the non‐weight‐bearing (NWB) or single leg full‐weight‐bearing (s‐FWB) conditions. CT examinations were performed using a noise index of 15 for a slice thickness of 5 mm, rotation speed of 0.5 sec, and slice thickness of 0.5 mm. The rotation of the 1MT was measured on the coronal CT image, which cut the sesamoids' bellies in the frontal slide of the first metatarsal and sesamoids perpendicular to the longitudinal bisection of the third metatarsal, and compared between the weight‐bearing conditions. Intra‐ and inter‐observer reliabilities of the rotation angle were also evaluated. The intra‐ and inter‐observer correlation coefficients were 0.961 and 0.934, respectively. The 1MT pronation angle was significantly greater in the s‐FWB condition than in the NWB condition (15.2° ± 5.4° vs. 12.5° ± 5.3°, P < 0.01). No sex difference was found in the magnitude of the 1MT pronation angle as a result of weight‐bearing. This study first demonstrated that pronation of 1MT occurs due to natural full‐weight‐bearing in asymptomatic feet. The 1MT's rotational movement under weight‐bearing conditions may relate to the onset and pathogenesis of the hallux valgus. Clin. Anat. 32:715–721, 2019. © 2019 Wiley Periodicals, Inc.
