    Purpose: To verify the prevalence of types of metatarsal formula (FM) in patients with primary metatarsalgia, through x-rays. Assess the association between shortening of the first metatarsal and metatarsalgia in comparison to a control group (CG). Analyze the intra and interobserver reproducibility by methods of transverse lines (MLT) of Morton and arcs (MA) of Hardy & Clapham. Methods: a cross-sectional observational study was conducted in 112 radiographs of the feet, being 56 of GM and 56 of GC evaluated in the period between december 2012 and june 2013. The measurements were made by three third-year residents in orthopaedics, with previous training methods, using a template to decrease the chance of error and disagreement. Results: there was no agreement on any of the two methods by Bland-Altman graphs, but through the intraclass correlation coefficient was verified a greater intra and interobserver reproducibility by MLT (0,78 and 0,85) in relation to the MA (0,73 and 0,60). When comparing both groups, it was observed statistical difference (p ≤ 0,05) with a shortening of the first metatarsal (3,39mm) higher in GC in relation to GM (2,14mm). In patients with primary metatarsalgia, FM type index minus was more prevalent by MLT (62,5%) and the type zero plus by MA (71,4%). Conclusions: In this study, it was observed that the prevalence of FM depends on the method of measurement. When comparing both groups, there was association of the shortening of the first metatarsal with the GC. There were no intra and interobserver agreement in any of the proposed methods.
