将生物可吸收骨折固定板加热到其玻璃化转变温度以上，使它们暂时具有延展性，从而促进它们适应下面的骨骼几何形状，尽管加热的后果尚不清楚。在不同条件下加热聚（L-丙交酯-共-乙交酯）共聚物样品，并评估对样品力学的影响。加热暂时增加了韧性，同时略微降低了弯曲模量。没有发现对体外材料降解的持久影响。
Heating bioabsorbable fracture fixation plates to above their glass transition temperature renders them temporarily malleable, thus facilitating their adaptation to the underlying bone geometry, although the consequence of heating is not well understood. Poly (L-lactide-co-glycolide) copolymer specimens were heated under various conditions, and the effects on specimen mechanics were assessed. Heating temporarily increased toughness while slight reducing flexural modulus. No lasting effects on in vitro material degradation were seen.
