A Fresh Look at High Ankle Sprain Treatment in the Absence of a Fracture
High ankle sprains are a common injury, specifically amongst collegiate athletes participating in high impact sports such as football, wrestling, and hockey. In the event of a high ankle sprain, the anterior inferior tibiofibular ligament, otherwise known as the AITFL, is partially or completely torn, separating the tibia from the fibula, and leaving the athlete with a long and strenuous recovery. Treatment of the injury depends on the severity, specifically related to whether the fibula fractures and the type of tear. The new designs and techniques being developed will aim to effectively address concerns with current treatment options by providing a comprehensive surgical care kit. The use of surgical tools will further aid in stabilization and healing of the ligaments in situations where more noninvasive treatment options prove unsuccessful. From the information gathered through research, modeling, and testing, the best and most optimal design for treating a high ankle sprain injury with a torn AITFL was determined to consist of using Orthocord suture along with a winged screw to fixate the torn ligament into the posterior end of the bone. An injection of PRP from the patient’s own blood to the site of injury would help expedite the recovery process and prevent chances of chronic ankle instability and post-operative osteoarthritis.
