Abstract

[Indexed for MEDLINE] 19. Clin Podiatr Med Surg. 1988 Apr;5(2):393-420. Fractures of the neck of the talus and the Blair fusion: a review of the literature and case report. Simin RM(1), O'Neill CJ Jr, Karlin JM, Silvani SH, Scurran BL. Author information: (1)Department of Podiatric Medicine and Surgery, Kaiser Permanente Medical Center, Sacramento, California. Historically, fractures of the neck of the talus have been serious injuries with sometimes devastating results. Several mechanisms have been reviewed to explain the types of injuries most commonly seen. Hawkin's classification of the types of talar neck fractures has been explained and used as a guideline in a review of treatment and results of talar neck fractures. Hawkin's group I fractures generally require only immobilization and are frequently without serious sequelae. Hawkin's group II fractures are more serious injuries, which may frequently be treated with closed reduction. Open reduction is occasionally necessary. Hawkin's group III fractures have the most potentially devastating results. These generally require open reduction with internal fixation or occasionally primary salvage procedures. Secondary salvage procedures are also sometimes necessary. Avascular necrosis of the talar body is reviewed in detail, including correlation with the type of fracture as well as diagnostic techniques and treatment. Other complications, including soft-tissue damage, osteomyelitis, malunion, and posttraumatic arthrosis, are discussed. The Blair tibiotalar arthrodiesis is reviewed in detail, with the consideration that it may be used as a primary or secondary salvage procedure with good results. Finally, a case in which the Blair fusion was used successfully is reported with 1-year follow-up.
