Bi-trimalleolar Fracture and APOS System Treatment

APOS System Effects in Post-operation Bi-trimalleolar Fracture of Ankle Prospective, Comparative Randomize Trial Study

The purpose of this study is to evaluate of functional tests and clinical findings with APOS System treatment in patient after bi-trimalleolar fracture of ankle. These functional changes will be evaluated AOFS, FAOS, SF36 and WOMAC scores, walking laboratory GAITRite and clinical examination.

Trial design Prospective, comparative, randomize trial. The patients after surgery due to bi or trimalleolar fracture of ankle, that were referred to the physiotherapy treatment, 3 weeks cast and 6 weeks from surgery with full weight bearing indicated by orthopedic

• The population will randomized separated in trail and control group/ Both receive APOS shoes The trial group will receive APOS walking system

• The control group will receive the same walking protocol as the trial group without biomechanics units.
