The Mechanical Strength Of A Biphasic Polycaprolactone Bone Scaffold For Medial Open Wedge High Tibia Osteotomy Implantation
Mechanical strength is a requirement of the bone scaffold for osteoarthritis treatment by the medial open wedge high tibia osteotomy (MOWHTO). The mechanical compression of the scaffold which depends on material concentration and structure must be concerned in MOWHTO substitution due to help to prevent the delayed bone healing process from scaffold collapse. This study was divided into two sections: (i) the influence of varying concentrations between DBM-HA mixed PCL scaffold (20/80, 30/70, and 40/60 % wt./wt. DBM-HA/PCL) on compressive strength, and (ii) the compressive strength of the 0°-90° orientations DBM-HA/PCL scaffold (20/80% wt./wt.) constructed with 300-500 μm pore dimension…
Toughening 3D-printed Sr–HT–Gahnite caffold through natural and synthetic polymer coating
Bone scaffold for aiding bone regeneration in large bone defects should have following ideal characteristics; biocompatibility, biodegradability, bio-activity, high porous and interconnected-pore architecture, as well as, mechanical characteristics similar to the cortical bone for supporting loads. 3D printed Sr–HT (Sr–Ca2ZnSi2O7)–gahnite scaffold with hexagonal pore structure is an interesting bone scaffold meeting most of these ideal features. To explain, biocompatible, osteoinductive, and osteoconductive properties as well as unique high compressive strength are obtained from Sr–HT–gahnite, glass-ceramic, material. With hexagonal pore structure, the scaffold has compressive strength comparable to cortical bone balancing with high porosity and large pore size. Nonetheless, the scaffold…
