[Connection between Böhler's angle and subtalar arthrodesis after calcaneal fracture (author's transl)].

Subtalar arthrodesis is a common intervention after comminuted fractures of the calcaneum. To clarify the connection between fracture of the calcaneum and the negative late results, all 81 subtalar arthrodeses following calcaneal fracture which had been carried out from 1959-1980 in the Munich Orthopedic Hospital were classified according to type of treatment of calcaneal fracture, radiological signs of arthrosis, Böhler's angle and the interval between fracture and arthrodesis. It can be shown that subtalar arthrodesis after comminuted fractures of the calcaneum may be necessary, irrespective of the Böhler's angle and the signs of arthrosis visible in the röntgen picture. Consequently the interval between the fracture and the arthrodesis is of subordinate significance. The most important parameter is the patient's pains.
