title: [A preliminary clinical study on absorbable screws].
abstract: To evaluate the application of self-reinforced ploy-DL-lactide (SR-PDLLA) absorbable screws in the treatment of spongy bone and intra-articular fractures, the internal fixation with SR-PDLLA absorbable screw was performed on 58 cases,of which 25 were medial malleolus fractures, 14 condyle of humerus fractures, 9 tibial plateau fractures, 7 ulnar olecranon fractures, and 3 lateral malleolus fractures. Observations were made on the orthopaedic operation sites and overall conditions frequently and radiography was performed for periodic analysis. The results showed that SR-PDLLA absorbable screws were particularly effective and reliable, they had good biocompatibility in the treatment of spongy bone and intra-articular fractures and could be used safely in clinical practice.
