Effect of CAM boot immobilization on weightbearing stability in syndesmotic injuries: a cadaveric study

摘要

Category:TraumaIntroduction/Purpose:Ankle injuries are one of the most frequent traumas of the lower limb. They typically involve the lower lateral ligaments of the ankle, but the syndesmosis is also affected in up to 18% of cases. The degree of instability of syndesmotic joint depends on which ligaments are affected. Adequate management of syndesmotic injuries is crucial to avoid long term complications. The primary goal of our study was to evaluate the effect of simulated weightbearing on syndesmotic instability resulting from isolated AiTFL injury and from combined AiTFL/IOL injuries. The secondary goal was to evaluate the effect of a controlled ankle motion walking boot on syndesmosis stability following injury. We hypothesized that the CAM boot would prevent significant instability even in two ligaments injuries.Methods:Ten cadaveric specimens were dissected to expose the syndesmosis to create progressive iatrogenic syndesmosis ruptures. Uninjured syndesmoses were compared to isolated AiTFL and combi...
