Compression Therapy for Swelling Management Following Ankle Injury

Overview

After an injury or undergoing foot/ankle surgery, patients often experience swelling in the injured area. Under current standard of care, plaster casts are removed at six weeks and patients are put in a walking boot. At this point in time of their recovery, patients are permitted to weight bear and move in their walking boot without other help, like crutches. This has shown to cause a significant amount of swelling in the ankle and foot between week six and twenty-six post-injury/surgery. There is not much research that has looked at the effects of compression on reducing swelling in post-operative and non-operative ankle fracture, mid-foot, hindfoot, or ankle arthrodesis. This research is important because post-injury swelling can lead to wound complications and limit functionality. Therefore, finding new ways to reduce swelling could help prevent future complications. The purpose of this study is to see if the Bauerfeind ankle compression sleeve is a safe post-operative/injury foot and ankle swelling management tool. Use of a compression sleeve will be compared to just using a walking boot, which is current standard of care, to determine if the compression sleeve reduces post-operative/injury foot and ankle swelling. The study will follow patients improvement in swelling and pain. The compression sleeve will also be assessed for product safety. Safety is determined by watching the frequency, severity and seriousness of any side effects or complications, known as adverse events, that may be experienced while in the study. The Bauerfeind ankle compression sleeve has been and is currently used in humans as a swelling reducing devise in the foot and ankle but has not been studied in a randomized control trial.

This research study aims to assess swelling at 6, 12 and 26 weeks post non-operative and operative ankle fracture, mid-foot, hind-foot or ankle arthrodesis. Under current management, plaster casts are removed at six weeks and patients continue care in a walking boot. At this point in time of their recovery patients are permitted to weight bare and move in their walking boot without other aids. This has shown to cause a significant amount of swelling in the ankle and foot between week 6 and twenty-six post-injury/surgery. To minimize swelling this study proposes the use of an ankle compression sleeve to wear during management once the plaster cast has been removed at 6 weeks. There is limited literature examining the effects of compression on reducing swelling in post-operative and non-operative ankle fracture, mid-foot, hindfoot, or ankle arthrodesis. This research is important as post ankle injury swelling can lead to wound complications and limit functionality. Thus, identifying management tools that reduce swelling may limit future complications. Patients at the Queen Elizabeth II Health Sciences Centre that are undergoing non-operative ankle fracture management, ankle fracture surgery, or hind-foot, mid-foot, or ankle arthrodesis that meet the inclusion and exclusion criteria and willingly consent to the study will be included in the study's participant pool. Participants will be randomly assigned to control and intervention groups. Both groups will undergo a volume displacement swelling measurement of each foot at 6 weeks post operation/injury. Patients in intervention group will be given a Bauerfeind ankle compression sleeve to wear under the walking boot for the rest of their management protocol. Patients will undergo volume displacement and compliance/ accessibility questionnaires during their twelve week and 6-month post operation/injury clinic visits. Data will be summarized and compared between groups and within groups at at 6, 12 and 26 weeks post operation/injury for change in swelling.
