The study was to evaluate the complete absorption time of bioabsorbable plates in surgery and adverse tissue reactions of the type of plates. The results show that time of full absorption of PLLA is 4.57 years, time of full absorption of P(D/L) LA is 2.41 years, time of full absorption of PGLA is 1.26 years. Adverse tissue reactions of PGLA is the lowest (0.087 percent). In conclusion, PGLA bioabsorbale plates has appropriate absorption time and has the lowest adverse tissue reactions, which can be widely used.
