Tibiotalar arthrodesis for injuries of the talus.
BACKGROUND
Fracture-dislocation of the talus is one of the most severe injuries of the ankle. Opinion varies widely as to the proper treatment of this injury. Since Blair's original description of the tibiotalar fusion in 1943, there is little mention in the literature of his method. The present study reports the results of tibiotalar arthrodesis with modification in Blair's technique.


METHODS
Eleven cases of modified Blair's tibiotalar arthrodesis were retrospectively studied. The average age was 32.4 years (range, 26-51 years). Six patients had posttraumatic avascular necrosis; five had neglected fracture-dislocation of the talus.


RESULTS
The mean followup is 8 years (range 3-12 years). Tibiotalar fusion was achieved in all the ankles at an average of 20.5 weeks (range 16-28 weeks). Nine cases having 15 degrees -20 degrees tibiopedal motion had excellent results and two ankles having 10 degrees -15 degrees of tibiopedal motion had good result.


CONCLUSIONS
We achieved good long term results with tibiotalar arthrodesis with modification in Blair technique. The principal modification in the present study is retention of the talar body while performing arthrodesis with anterior sliding graft. The retention of the talar body provides intraoperative stability and in the long term, the retained talar body shares the load transmitted to the anterior and middle subtalar joints thus resulting in improved hind foot function and gait.
