Talar neck fractures represent a serious injury, and a review of the literature
reveales the incidence of poor results is disappointingly high. Between June 1985 and April 1993, 35 cases were admitted to our hospital with fracture of talar neck. Seven patients were lost to follow-up and were thus excluded from this study. Of the remaining 28 fractures of talar neck, 8 were Hawkins' Type I injury, 11 were Type II injury, and 9 were type III injury. Type I fractures were treated with the closed method, while the Type II and III fracture- islocation were treated operatively. The rate of avascular necrosis (AVN) of Type I injury was 12.5%, Type II injury was 54%, and Type III injury was 100%. The average follow-up was 53 months. The results were evaluated with Hawkins' criteria. For Type I injury, all patients achieved good or execllent results. For displaced talar neck fractures (Type II and III), 50% of the patients achieved good or excellent result. Prompt open reduction and internal fixation are recommended for displaced fracturedislocations of the talar neck. Anatomic reduction, bony union and early rehabilitation are the goals of the treatment, even though A VN is inevitable. There is no direct relationship between the development of A VN and permanently disabling symptoms. |
