PROGNOSTIC-SIGNIFICANCE OF POSTERIOR SUBTALAR JOINT ARTHROGRAPHY FOLLOWING FRACTURES OF THE CALCANEUS

Nineteen patients with 22 intra-articular fractures of the calcaneus w ere investigated by posterior subtalar joint arthrography after 6 (2-1 5) months following injury, and their clinical symptoms were compared with the arthrographic findings. The arthrograms were classified into four types based on the findings of the joint space of the posterior s ubtalar joint in Anthonsen's view, The classification correlated signi ficantly (P = 0.03) with the clinical results which were assessed afte r 23 (9-41) months following injury. We conclude that posterior subtal ar joint arthrography has prognostic value in assessing patients with fractures of the calcaneus.
