Talar neck fracture: prevalence of Hawkins sign in patients submitted to surgical treatment

Abstract

Objective: To evaluate the prevalence of Hawkins sign in patients with talar neck fracture and characteristics of individuals admitted for surgical treatment of this injury. Methods: We analyzed medical records of 18 patients with talar neck fracture admitted between October 1, 2010 and October 3, 2015 to the Hospital Universitário Ciências Médicas in Belo Horizonte/MG. Analyzed variables were sex, age, mechanism of trauma, time between date of fracture and date of the surgery, Hawkins classification, Hawkins sign, presence of osteonecrosis and AOFAS score. Results: We found a prevalence of 55.6% of Hawkins sign in surgically treated patients. Of these, all evolved without osteonecrosis of the talar body. Conclusion: Talar neck fractures are more common in young men. Patients who hadpositive Hawkins sign did not evolvewith osteonecrosis. However, those with negative Hawkinssign, 50% of them evolved with this complication.
