Brief Summary

Patients often seek advice from their treating doctor if they are able to drive with a foot orthosis after a first metatarsal osteotomy for symptomatic hallux valgus and/or after an additional forefoot surgery. This challenging question is of obvious importance for the patient and other road users. Previous studies already issued driving ability after different orthopedic procedures and with knee and ankle devices on the brake reaction time but missed to address the same for foot orthoses after hallux valgus or forefoot surgery. This missing evidence made us evaluate the influence of wearing a foot orthosis after a first metatarsal osteotomy or forefoot surgery on driving ability (brake response time; BRT). The overall time frame is about nine weeks; each appointment for BRT measurement takes about fifteen to twenty minutes. The first BRT measurement is one day before the foot surgery without a foot orthosis (normal shoe)and with the orthoses (control run) (1) at two days (2), two weeks (3), four weeks (4) and six weeks (5) after the operation with a HVS and a FRS and eight weeks postoperative without a foot orthoses (6).
