Nine osteotomies of the neck of the mandibular condylar process in sheep were fixed with self-reinforced poly-L-lactide screws and nine with metallic screws; two osteotomies were left unfixed. Radiographic examination was carried out at 3 weeks. The animals were killed at 6, 12, and 24 weeks. Malalignment was detected at 3 and 12 weeks in both unfixed condyles. The consolidation of the fixed osteotomies seemed to be faster in the polylactide group than in the metallic group. There were no complications in the healing of the fixed osteotomies.
在绵羊的下颌髁突颈部进行了9处截骨术，其中9处用自增强聚-L-乳酸螺钉固定，9处用金属螺钉固定；2处截骨术未进行固定。在3周时进行了影像学检查。在6周、12周和24周时处死动物。在3周和12周时，未固定的髁突均检测到排列不齐。聚乳酸组固定截骨术的愈合似乎比金属组更快。固定截骨术愈合过程中未出现并发症。
