Complications and long-term results of ankle arthrodeses following trauma.
A review of sixty patients who had undergone ankle fusion for post-traumatic arthritis revealed that thirty-five (58 per cent) had the procedure performed within the first year after injury. A total of forty-eight complications occurred in twenty-nine (48 per cent) of the patients. Frequent complication were infection (23 per cent), non-union (23 per cent), inadequate surgical alignment or early loss of position (15 per cent), malunion (12 per cent), and delayed union (7 per cent). The lateral transfibular approach had the highest incidence of complications, and a two-incision approach using the Charnley compression apparatus was the procedure with the fewest complications. Forty-one patients were followed for an average of 7.5 years after operation. Of these, thirty-four (83 per cent) were satisfied with the procedure. Examination of thirty of the forty-one patients at an average of 7.3 years after surgery revealed virtually no subtalar motion but motion of 13 degrees at Chopart's joint. With shoes, patients had a near-normal gait. The roentgenograms revealed a minimum amount of degenerative arthritis at Chopart's joint, which may worsen with time. Varus or valgus angulation of the hind part of the foot was associated with a greater degree of symptoms in the subtalar area as well as the middle of the foot. The neutral position in varus-valgus angulation as well as dorsiflexion-plantar flexion was the optimum position for both men and women. The results of the procedure did not deteriorate with time.
