title: [Applied researches on polylactide internal fixation devices].
abstract: Nowadays, more and more basic and clinical researches on polylactide internal fixators were carried out in China. In this paper are reviewed the researches of polylactide acid(PLA), including its physical and chemical characters, biodegradation, absorption and mechanical properties, effects on fracture healing, and clinical application. Some problems that have not been solved are high-lighted and discussed. Also dealt with are some researches of PLA in future.
