10 Common FAQ about PLLA/HA and Bone Regeneration
Post written by : Wong Yuen Lam 1. What is the expected rate of degradation with PLLA/HA materials? For degradation time , According to Fig. 1, PLLA loses 90–93% of its inherent viscosity by week 52 in vivo. However, this molecular breakdown is distinct from complete resorption. High-molecular-weight PLLA typically requires 2 to 5.5 years for complete structural clearance and resorption. Fig 1. displays the degradation profiles of bioabsorbable PLLA spinal fusion cages measured by changes in...
