Anterior tibial striations.

Radiolucent horizontal striations of the anterior cortex of the tibia were seen in 10 athletes who were evaluated for "shin-splints." There were seven basketball players, two professional dancers, and one hurdler. Each patient's history included vigorous leaping in performance of athletic feats. All the lesions were similar in location and appearance and were accompanied by thickening of the anterior tibial cortex. These striations are considered stress fractures and were not observed in a group of runners who were evaluated for shin-splints.
