Design outcomes

Primary

Measure	Time frame
stable and unstable hallux valgus It will be investigated, whether there are differences in x-rays or mris between persons with stable and unstable hallux valgus. In the x-rays some angles (HV-angle, intermetatarsal-angle, meary-angle) and the length of the first metatarsal bone (also compared to the second one) will be examined. In the mris the volumes and some cross sectional areas of abductor hallucis muscle and flexor hallucis brevis muscle will be measured.	—
