A comparison of absorbable screws and metallic plates in treating calcaneal fractures: a prospective randomized trial.

Background: Intra-articular calcaneal fractures are more likely to suffer consequences in terms of pain and disability. Many studies have suggested that operative treatment for these fractures may result in better outcomes than nonoperative treatment. The metallic screws and plates are among the most common alternatives to stabilize calcaneal fractures.
