摘　　要：BACKGROUND Arthrodesis is the surgical fusion of a diseased joint for the purposes of obtaining pain relief and stability.There have been numerous fixation devices described in literature for foot and ankle arthrodesis,each with their own benefits and drawbacks.AIM To review the use of intraosseous devices in foot and ankle surgery.METHODS There were 9 papers included in the review(6 clinical and 3 experimental studies)all evaluating arthrodesis in the foot and ankle using the IOFIX device(Extremity Medical™,Parsippany,NJ,United States).Outcome scores,union rates,as well as complications were analysed.RESULTS IOFIX appears to be safe and effective in achieving arthrodesis of the 1st metatarsophalangeal,and talonavicular joints with early rehabilitation.In comparison to plate/screw constructs there were fewer soft tissue complications and issues of metalwork prominence.Cadaveric and biomechanical studies on the use of intramedullary fixation for fusion of the tarsometatarsal and ankle joint showed decreased load to failure,cycles to failure and stiffness in comparison to traditional fusion methods using plates and screws,however IOFIX devices produced higher compressive forces at the joint.CONCLUSION We describe the reasons for which this biomechanical behavior of the intraosseous fixation may be favorable,until prospective and comparative studies with largersample size and longer follow-up confirm the effectiveness and limitations of the method.
