BACKGROUND: The objective of our study is to evaluate the functional and subjective results following subtalar dislocations without any associated bone injuries and to examine whether the direction of dislocation has any effect on the post-traumatic results. METHODS: Over the period from February 1998 to May 2006, 56 patients with a subtalar dislocation were enrolled in the study. A subtalar dislocation without any associated bone injuries was only present in 13 patients. Follow-up examination after an average of 39.8 months was performed using the AOFAS Ankle-Hindfoot scale. The adapted classification developed by Altman was used to assess the post-traumatic degree of arthrosis radiologically. RESULTS: The average AOFAS score was 81, with good results in 11 patients and satisfactory results in 2 patients. The range of motion (ROM) for the ankle-hindfoot joint was 39.2 degrees . CONCLUSION: Despite the severity of the injury, the functional and subjective results of subtalar dislocations without any bone injuries are good. Generally, no early post-traumatic arthrosis occurs if there are no associated bone injuries. No differences were established between medial and lateral subtalar dislocations.
