[Does excessive stress play a role in the development of osteochondrosis dissecans tali?]

At the follow-up examination of 61 patients with Osteochondrosis dissecans tali (OD) we found at 48 of them one or more injuries in the anamnesia. More than 70 percent of them had as an injury mechanism a supination trauma. In case of medial OD the possible cause of an OD is given by the ratio 34 to 12 of trauma and non-trauma. The ratio in case of a lateral OD is 14 to 1 and it almost definitely points to overstress being a cause of it. Primary reasons may be here sports, especially football.
