|- Brief summary||Rationale: |
Angular measurement is an important tool for the choice of treatment of hallux valgus deformity. Literature has suggested treatment flow charts for treatment depending of the intermetatarsal (IMA), hallux valgus (HVA) and distal metatarsal articular angles (DMAA). In orthopedic surgery both weightbearing and non-weightbearing foot radiographs are used for measurement of these angles. Little is known about the influence of weightbearing on these specific angles.
Patient outcome and satisfaction questionnaires are increasingly popular in modern medical and surgical follow up. Unfortunately, for forefoot problems no Dutch validated questionnaires is available.
Part one: To quantify the influence of weightbearing on the IMA, HVA and DMAA in patients with a hallux valgus deformity, measured according the actual gold standard of measurement.
Part two: Validation of the Dutch version of the Foot Ankle Outcome Score (FAOS) and the Dutch version of the Manchester-Oxford Foot Questionnaire (MOXFQ) for patients with first ray deformity.
The study will comprise two parts. Patients will be included according to the GCP principle. For part one, patients will undergo a physical examination and 4 radiographs will be made of each foot. (Antero-Posterior (AP) weightbearing and non-weightbearing & Lateral (LAT) weightbearing and non-weightbearing). Angular measurements will be performed according to the gold standard. For part two, patients with first ray deformity will be asked to complete a set of questionnaires, including the Dutch version of the FAOS, MOXFQ, SF-36 and VAS pain and limitation. Two weeks later patients will receive a new set of questionnaires to be completed at home and have to be returned to the orthopedic department.
Patient referred to the orthopedic outpatient clinic for a foot problem are eligible for inclusion in this study. Primary study population will be patients with a hallux valgus deformity. For part two of the study, patients with first ray deformity in general will be asked to complete two sets of questionnaires.
The intervention is referring the patient for an extra set of two radiographs (AP non-weightbearing and LAT non-weightbearing) per included foot.
Main study parameters/endpoints:
For part one: Influence of weightbearing on IMA, HVA and DMAA in patients with hallux valgus deformity.
For part two: Validation of the Dutch version of the FAOS and MOXFQ for first ray deformity.
Nature and extent of the burden and risks associated with participation benefit and group relatedness:
Each extremity radiograph (e.g. foot) exposes the patient to <0.01mSv. This means that included patients will receive <0.02mSv extra per included foot. This amount is negligible compared to the yearly background radiation at sea level (2-3 mSv). According to the guidelines of the ICRP occasional diagnostic radiography of the extremity is highly unlikely to cause malignancy.
