Ninety-four conservatively treated patients with Lauge Hansen Stage II supination-eversion fractures of the ankle were interviewed after 16-25 years. Patients with pain were examined clinically and radiographically. Eighty-nine patients had good and five medium results. Our observations compare well with published reports of open treatment. We conclude that this particular fracture type is so benign that it can be treated closed without reduction.

The intra-osseous pressure, P02, and PCO2 were measured in 32 hips (21 patients) which were painful but showed no severe degenerative changes. Pre-operative scintigraphy and radiography was performed in all patients. Thirteen hips showed early osteoarthritis, eight had early osteonecrosis, and 11 had no changes. Core biopsies were performed and the bone was examined histologically and graded for necrosis.
