Ankle Mortise Instability-A Case Study

The deltoid ligament represents a strong link in providing stability to the ankle foot complex and is usually injured/sprained following high impact activities. Conditions like osteoid osteoma near the lower end of tibia may produce pathological weakness in the ankle foot complex thus rendering structures as strong as MCL more susceptible to sprains leading to ankle foot instabilities and pain.

The following case depicts the importance of sound examination and clinical assessment in a patient with recurrent ankle foot complex pain after recovering from deltoid ligament injuries.
