The dynamic vacuum orthosis: a functional and economical benefit?

In a prospective, randomised study, 27 patients with internally fixed ankle fractures were treated post-operatively for a period of six weeks by application of either a new dynamic vacuum orthosis with permitted mobilisation to 10 degrees -0 degrees -10 degrees at the ankle joint or a synthetic cast. Full weight bearing was allowed in both groups after two weeks. The cast group was prescribed four weeks of physiotherapy following six weeks of immobilisation. After ten weeks, the Olerud and Molander score showed a significant difference in favour of the orthosis. Early functional outcomes were significantly better for this group after six weeks and ten weeks. Patients in the orthosis group who were in formal employment returned to work 24 days earlier than those in the control group. Treatment of the orthosis patients took up three to four times less working time for the medical personnel. A saving of 38 euros on directly ascertainable costs could be evaluated. Rehabilitation of ankle fractures with a dynamic vacuum orthosis leads to better early functional results and greater patient satisfaction. The orthosis fulfils the conditions for early return to work. Treatment with an orthosis not only reduces working time for medical personnel but economises on expenditure for treatment and rehabilitation.
