Abstract
Fracture of neck of talus is a rare one affecting mainly young active people. Most serious fractures of the talus are high-energy injuries. Fractures of the talar neck are commonly the result of a hyperdorsiflexion-type injury. It has a devastating effect on economical and psychological aspects of the patients. This study aimed at evaluating the efficacy of percutaneous cannulated screw fixation of acute talar neck fracture using both techniques posterior to anterior and anterior to posterior and to determine the rate of AVN and overall outcome in these patients. Twenty patients with less than 5 days old fractures were fixed percutaneously by cannulated screws either from anterior to posterior or from posterior to anterior and followed up for a minimum 15 months (average 24 months). Patients were 15 males and 5 females with an average age 35 years. According to Hawkins classification, 5 fractures were classified as type I and 15 fractures as type II. All the 20 patients were evaluated for clinical and radiological results. This study proved that closed reduction and percutaneous fixation of acute talar neck fractures resulted in predictable satisfactory union rate and functional outcome. Also, it proved that insertion of cannulated screws preserves soft tissue around talus and thereby lowered the incidence of avascular necrosis. Lastly, preservation of initial fracture hematoma which is one of the major advantages of minimal invasive trauma surgery explained the absence of non united cases and low incidence of delayed union and AVN.
