Ski fractures of the femur.

There have been few reports of femoral ski injuries. Twenty-four cases of femoral ski fractures (as well as one dislocation), collected over 8 years, are presented. Two-thirds of the patients were under 30 years of age. The largest single cause of injury (one-third of the cases) involved collision. High speed skiing with loss of control and falling on icy surfaces were other frequent causes of injury. Internal fixation methods were usually chosen for skeletally mature patients, with traction and casting used in children. Femoral injuries have occurred in recent years despite improvements in ski equipment, snowmaking, and trail-grooming. It is felt that these improvements have led to faster skiing with increased kinetic forces of injury, and more severe consequences of a fall or collision.

Osteochondral fractures of the dome of the talus.

Fractures of the talor dome are uncommon and may elude diagnosis despite routine roentgenograms of injured ankles. Tomograms are helpful in localizing this lesion. Surgical removal of the osteochondral fragment is often indicated. Medial lesions may be inaccessible except by osteotomy of the medial malleolus which is then fixed with a bone screw. Lateral fragments are approached through anterolateral or posterolateral ankle incisions. Of 9 symptomatic ankles, 6 had satisfactory results following surgery. The other 3 were treated conservatively, one improved; two did not. One additional asymptomatic ankle remained so with no treatment. In one case the talus also contained an unusual cystic lesion; in another there was tarsal coalition.
