Radiological Evaluation of a High Ankle Sprain

Lengthening z-Osteotomy of the Fibula to Correct Persistent Talar Shift Following Open Reduction Internal Fixation of Ankle Fractures

“…However, partial syndesmotic injuries and those that do not cause diastasis may not be recognized by conventional plain radiographs and magnetic resonance imaging should therefore be considered for complete evaluation of the ankle. 6 We have described our experience with the technique of suprasyndesmotic lengthening z-osteotomy to correct malunited ankle fractures. In all cases, a dynamic compression plate and syndesmosis screws were used, and we believe that these 2 adjuncts to conventional fixation were pivotal in the satisfactory outcome seen in all cases.…”

Sonography of the ankle: The lateral ankle and ankle sprains

“…This type of injury is often missed without the presence of an associated fracture or frank diastasis. Syndesmotic injuries often have a relatively rapid resolution of external swelling and bruising; therefore, the athlete can often walk almost immediately with little pain . Delayed or missed diagnosis can result in instability, with a decreased response to surgery.…”

“…Delayed or missed diagnosis can result in instability, with a decreased response to surgery. Bone scans and computer tomography are relatively reliable, and MRI is generally the modality of choice for diagnosing syndesmotic injuries . Ultrasound has inherent advantages in diagnosis, having real time and dynamic modes.…”

Syndesmotic Ankle Sprain

“…In Types 1 and 2 injuries, the patient is symptomatic for ankle sprain, yet fi ndings from plain x-ray fi lms may be read as negative. In Type 2, diastasis of the syndesmosis is seen on plain fi lms (Evans & Schucany, 2006). Type 3 ankle traumas show signifi cant diastasis on plain x-ray fi lm; the patient generally presents with concomitant fi bular fracture and an unstable ankle (Kirchner, Musgrave, & Musgrave, 2005).…”
