Abstract
This retrospective study aimed to determine if a transverse plane forefoot relationship
exists in patients with Jones fractures. Anteroposterior radiographs of 30 acute Jones
fractures were compared with radiographs of 30 asymptomatic control subjects. Radiographic
metatarsus adductus angle measurements were analyzed with a digital software program.
The reliability of the measurements was evaluated with an intra-rater study. An independent
t test was used to compare the metatarsus adductus angle between the Jones fracture
group and the control group. Radiographic analysis revealed the mean metatarsus adductus
angle for the Jones fracture group to be 20.22° (± 6.79°) compared with a mean of
14.27° (± 4.60°) for the control group. This difference between the groups was found
to be statistically significant (p < .005). The intraclass reliability coefficient (ICC = 0.9396) confirmed there was
no bias in the radiographic measurements. The metatarsus adductus angle in this group
of patients with Jones fractures was increased compared with the nonpathologic control
group. The Jones fracture mechanism of injury and resultant lateral column overload
may be intensified with an increased metatarsus adductus. This relationship should
be considered a risk factor for Jones fractures and taken into consideration with
respect to bone healing, treatment, and prevention.
